hubbard glacier growing

It’s not stopped,it’s stunned. Learn more. Hubbard Glacier, Alaska: See 661 reviews, articles, and 1,110 photos of Hubbard Glacier, ranked No.9 on Tripadvisor among 890 attractions in Alaska. Here are some facts about it! The Hubbard Glacier is the most famous growing glacier. Date of experience: July 2019. The glacier begins on Mount Logan, located in Canada, and stretches for 122 kilometers into the US. Happy Travelling! Photo (National Park Service), taken 4 days before dam rupture, that captures the full extent of the moraine and ice dam prior to the outburst. [8] This paper focuses on the region near Gilbert Point where two closures and outbursts have already occurred and where continued glacier advance threatens further closures of 60‐km‐long Russell Fjord (Figure 2). What do you think? Alaska tidewater glacier terminus positions, 1948–2012. This moraine was pushed against Gilbert Point and by late June, closed off Russell Fjord. The flow vectors show strong N–S shear and prominent E–W compression toward Gilbert Point. Due to damage which occured last summer to the power system, a temporary power solution fitted in September has failed. However, the closure was temporary, as water pressure overpowered the encroaching ice and debris and burst through the natural dam, returning the fjord to normal levels. Global Warming stuns very easily. 10 May 09 – This from climatologist Cliff Harris of the Coeur d’Alene Press. But since it is advancing…there are a few articles but mostly stuff about cruises. Hubbard Glacier and Russell Fiord study area. Awaiting the new discovery of the properties of ice being made more flowy by warming. Glacial outburst flood sediments within Disenchantment Bay, Alaska: Implications of recognizing marine jökulhlaup deposits in the stratigraphic record. Flow changed direction toward Disenchantment Bay with the flow pattern returning to predam conditions within a few days of the outburst. Variations in Alaska tidewater glacier frontal ablation, 1985–2013. NMFS vertical air photo mosaic of Gilbert Point dam (a) on 7 June 2002 and (b) on 7 July 2002. *Is the Hubbard Glacier growing? However, glacier instabilities such as surges of tributaries could trigger an anomalously rapid advance and close Russell Fjord at any time regardless of water depth. The advance runs counter to so many thinning and retreating glaciers nearby in Alaska and around the world. Outburst flood forecasting by monitoring glacier-dammed lake using satellite images of Karakoram Mountains, China. (2015) Glaciological and marine geological controls on terminus dynamics of Hubbard Glacier, southeast Alaska. Image of gray, alaskan, climate - 153519917 ... Last August was our second time cruising the Hubbard Glacier, although this time the excitement was gone. Photo about Hubbard Glacier showing growth layers and mountains in the background. [16] Bathymetric surveys of the area were conducted by the National Ocean Survey (NOS) in 1977–1978 [NOAA, 1984] and 1999 [NOAA, 2000]. The captain ofour ship, the Celebrity Millenium was great (a wonderful sense of humour). Water rise soon outpaced the rise in moraine height and breached the moraine dam. With nowhere to drain, runoff caused the water level in the fjord to rise rapidly. [24] Figure 7a shows the average ice velocity field during the period when the glacier and moraine dam were first being formed. The post outburst ice flow regime overall appears to have resumed its predam pattern, with velocity gradients and directions similar to Figure 7a. Figure 1. Am I missing something WGMS? ________________________________________ The Beauty of Blue Ice, The Power of White Thunder. There is something in nature on this planet that the “experts” don’t blame on the magic molecule CO2. If you’re wondering what the largest glacier in Alaska is, you got it. So you have the cojones to say that peer-reviewed science and all the worlds institutions of Science, which conclude AGW, are institutions of Religion, and YOU, an avowed rejecter of their findings, represent SCIENCE? Feeble brains or dishonesty–take your pick. [2003a] reported near‐terminus centerline speeds of 11.5 m d−1 during the summer of 2001 and seasonal velocity variations in the terminus lobe of up to 2 m d−1, slowing down in late summer. By Climatologist Cliff Harris . It’s also been very active in the past, having had two major surges in the past 30 years. However, a future surge, if powerful enough, could drive the terminus across even a deep water channel. All that summer, the new lake filled with runoff; its water level rose 25 metres (82 ft), and the decrease in salinity threatened its sea life. So, your criteria have now become ‘peer reviewed’ and in a ‘decent journal’. The article appears to be another ‘alarmist claim’ that ice is growing and will block all ports. Gilbert Point – The Automated Laser ranging system at Gilbert Point was replaced in late August with a new updated system. Yellow lines indicate the location of the terminus on August 1, 1978, and on July 13, 2002. I suspect the last possible thing alarmists can cite will be long-term land-locked ice (still responding to little ice-age). [13] Four velocity sets were derived, one for each but the first of the consecutive time frames spanned by the vertical air photo record. This glacier is the largest on the entire coast of Alaska. Jakobshavn Glacier in western Greenland is notorious for being the world’s fastest-moving glacier. Bruce. The solution is simple: CHANGE THE RECORDS. Which is it?

For surveys in Figures 8b, 8c, and 8d, depths are in meters with 5 m contour interval, and coordinates are UTM, NAD 83 zone 7. Rapid erosion of soft sediments by tidewater glacier advance: Taku Glacier, Alaska, USA, Journal of Geophysical Research: Earth Surface, http://ak.water.usgs.gov/glaciology/hubbard/, http://www.oceanservice.noaa.gov/dataexplorer/, end of outburst projected from discharge curve. Most are getting smaller, fast. The captain ofour ship, the Celebrity Millenium was great (a wonderful sense of humour). Off the coast of Yakutat—200 miles NW of Juneau—Hubbard is certainly gigantic: it's more than six miles wide where it meets the ocean. A glacier arch in Argentina has collapsed - but it's not due to climate change. And we’re still awaiting Anthony’s paper on data treatment. The Hubbard Glacier is the largest tidewater glacier in North America. Ice calving had widened the channel to ∼230 m by the next day (Table 1 and see Figure 7d). Local, not Global. The current advance of Hubbard Glacier is driven by its very high ratio of accumulation to total area (AAR) of 0.95, and we consider the glacier to be in the advance phase of the so‐called tidewater glacier cycle [Post, 1975; Meier and Post, 1987; Post and Motyka, 1995; Trabant et al., 2003a]. That doesn't mean melting is over. The captain ofour ship, the Celebrity Millenium was great (a wonderful sense of humour). [28] Bathymetric charts of the Gilbert Point area derived from the NOS 1977 and 1999 surveys and from our own surveys in 2002 and 2004 are shown in Figure 8. Terminus and moraine boundaries were derived from all photo sets. Advance of Hubbard Glacier and 1986 outburst of Russell Fiord, Alaska, U.S.A.

We believe that this sill acted as a sediment trap following 1986 and sediment accumulation behind the trap helped gradually fill the channel (see 1999 bathymetry, Figure 8b). @evanmjones [51] The combination of deep channel, strong tidal currents and warm ocean temperatures can similarly account for the reason the terminus has failed to cross the gap and close the fjord. I know French in Canada was 16th century French, although over the last two generations, modern French is being taught. At the current rate of sediment infilling, it may take another ten years before waters shallow to depths equivalent to the pre‐2002 event. These closures and subsequent floods are among the most significant glaciological events in North America in recent decades. Although the photos lacked stereo coverage, we were nevertheless able to measure terminus boundaries, moraine growth, and horizontal glacier flow in the vicinity of Gilbert Point. The doom and disaster is long overdue! Stearns cautions, however, that these closure dates are “projections based on our current observations, and should be viewed with DENIAL.” [22] Discharge was relatively slow at first but sufficient to begin eroding the moraine dam. Photo coverage barely extended into Russell Fjord and did not extend up glacier. Or dig a canal to bypass Gilbert Point? August 28, 2011 – Summer Activities However, d2w/dt2 is a numerical derivative that gets very noisy. in Modeling Earth Systems (JAMES), Journal of Geophysical Research You have to remember that these people are American, and…well you know. Thanks. “Projections”, so loved by CAGW, could be abbreviated to PCP’s or “probably crap predictions”. Witnessed on the Radiance of the Seas 8/7/2010. Photo dates and times are known to within a minute and therefore uncertainties in Δt are negligible. Increasing atmospheric temperatures can not be the cause of this, and the cause is very likely to be global cloud reductions, and hence increased surface sunlight, which will have a much greater effect on south facing slopes than north facing, and at lower latitudes versus higher latitudes. Today, most glaciers are slowly receding, with one notable exception. Future closures are of serious concern to residents of the nearby town of Yakutat because rising lake level could breach a 41‐m low point at the southern end of Russell Fjord (Figure 1). (a) Portion of NOAA Chart 16761 showing channel as it looked in 1977–1978, depths in fathoms. Seismic stratigraphic evidence for glacial expanse during glacial maxima in the Yakutat Bay Region, Gulf of Alaska. Hubbard Glacier has dammed Russell Fjord twice in historic times, once in 1986 and again in 2002. The discontinuity of the calculated erosion rates is due to a discontinuity in dB/dt, because, as described above, B was assumed constant until ice calving started and to then increase linearly afterward. Objects, Solid Surface These surveys serendipitously overlapped with the 2002 damming of Russell Fjord. A handful of Alaska glaciers are advancing and a few of those are getting bigger, but those are the exceptions. (Speaking of which, I visited the glaciers in NZ, which are retreating alarmingly. Off the coast of Yakutat—200 miles NW of Juneau—Hubbard is certainly gigantic: it's more than six miles wide where it meets the ocean. See http://wattsupwiththat.com/2015/06/22/the-hubbard-glacier-defies-climate-change-continues-to-grow/#comment-1969657, Actually, it’s either – it depends where you’re from , http://www.merriam-webster.com/dictionary/skeptic, Yes, Ken. Anthony is co-author of peer reviewed papers. Water levels to rose 0.24 meters (0.8 feet) per day. These measurements were primarily made in eastern Disenchantment Bay (EDB). The proglacial moraine was being pushed forward uniformly at about 4 m d−1, nearly identical to terminus ice flow at this location. “Walk toward the fire. The 2002 outburst proceeded in two stages: (1) relatively slow overtopping of the subaerial moraine with downward erosion rates of 1–2 m h−1 with little lateral expansion, (2) followed by faster downward erosion of the submarine moraine (up to 7 m h−1) with rapid lateral expansion of the channel by ice calving (∼7 m h−1). Please note: The publisher is not responsible for the content or functionality of any supporting information supplied by the authors. See Alaska's Hubbard Glacier advancing 7 feet per day! The new system utilizes a low-power two-way Iridium communication system that reduces overall power consumption and allows for increased data acquisition intervals (hourly). We addressed this by smoothing the record with a Gaussian of half‐width 40 min. It's possible that the glacier could close the fjord by later this summer if the current rate speeds up, says Harris. Not surprising – that part of NZ gets past 25C in summer which tends to have an effect on ice! and Paleomagnetism, History of I had it drummed into my head first in school and second when my 12 year old daughters memorized a couple of plays. The surface elevation has also been slowly increasing, particularly at lower elevations, at rates of about 1–2 m yr−1 [Trabant et al., 2003a]. The greater uncertainties in the last two periods reflect the short time interval between observations. Interestingly, observations and modeling results show different events happening near simultaneously: (1) the start of ice calving, (2) the moraine beginning to erode to below sea level, and (3) moraine erosion rates increasing. Properties of Rocks, Computational There, the advance averaged only 6 m yr−1. September 16, 2013 – HUbbard Glacier Update The glacier was then 190 m from Gilbert Point. Water temperature can also play a role during an outburst flood from a glacier‐dammed lake because water above 0°C can melt ice and widen the outflow channel [Walder and Costa, 1996]. They don’t seem to include some of the largest advancing glaciers in the world. And so we are presented with the difference between Science vs Religion, Hah… autocorrect incorrectly corrects “correct” into “correction”… I noticed that too – all about cruises etc. @Philip Bradley We have not measured tidal currents in the channel but our qualitative observations during bathymetry surveys suggest that they can reach several m s −1 at maximum flood and ebb. However, to our knowledge, Hubbard Glacier is the first historic instance of an advancing tidewater glacier damming a major waterway. “steadily advancing into Disenchantment Bay.” Gaia is using the only language at her disposal. You see this in Greenland and the Himalayas. Variations of erosion rates on shorter timescale cannot be expected to be resolved with this method. [58] Support for this work was provided in part by U.S. National Science Foundation grant OPP‐0221307, by NASA grant NAG5‐13760, and by U.S. National Park Service grant G‐2276. No need for “the warmist” to worry. Stearns, L.A. et al. Perhaps the British spelled it with a ‘k’ 250 years ago? Geophysics, Geomagnetism The lateral extent of the 7 July 2002 ice and moraine dam (short‐dashed lines) is also shown. [1976], who reported temperatures in EDB ranging from a minimum of 2.75°C in March–April to a maximum of 7°C in late August–September in 1973. All Antarctic glaciers outside the peninsula are north facing, so fit the general pattern.of retreat versus advance. He said that’s all from climate change and then looked all spiritual in his eyes. [29] A cross section of submarine topography in the channel based on the 1999 and 2002–2005 annual bathymetric surveys is shown in Figure 9. 1. Although the temperature of the water was not checked, it should be noted that water exists in liquid form from 32 all the way up to 212 degrees F. ED … There, now THAT’S poking with a stick. The article doesn’t mention the Hubbard is the largest tidewater glacier in North America. We derived a discharge curve as shown in Figure 6 by differencing the water level data during the outburst period, using methods and fjord hypsometry described by Mayo [1989]. The Hubbard Glacier is North America’s largest tidewater glacier. Regions westward along the terminus into Disenchantment Bay lacked shoreline control necessary for photogrammetric analysis. As a consequence, upstream ice flow decelerated from 5 m d−1 to 1.5 m d−1, with flow diverging to either side of Gilbert Point. Post was not sent - check your email addresses! March, and D.S. Bathymetric surveys of Gilbert Point channel. It would be money well spent compared to the billions spent on “climate Change”. The 1986 outburst stripped the sediments from Gilbert Point to depths exceeding 35 m [Trabant et al., 1991] and redeposited them in Disenchantment Bay [Cowen et al., 1996], appreciably deepening the tidal channel and widening it to 300 m. Channel width was still about 300 to 400 m in 1999 and water depths averaged about 25 m. [9] Despite predictions of imminent glacier readvance and damming [Trabant et al., 1991], the next closure did not occur until 2002. Dam erosion rates derived from the water level record. Of course.

David C. Finnegan/CRREL https://en.wikipedia.org/wiki/Br%C3%BCggen_Glacier. Billy, Warren, et al, Some good news from the thin ice. Processes in Geophysics, Atmospheric Landsat image of terminus position of Hubbard Glacier on 1 October 2000. We saw the Hubbard Glacier while cruising on our Viking Orion cruise ship. FULL SCREEN - HD -From the cruise ship ms Ryndam on May 28,2009. We in fact observed undercutting of freshly calved ice faces at the water line by a meter or more over a period of a few hours during our late‐summer bathymetric surveys at Gilbert Point. Hubbard advanced to within 70 m of Gilbert Point in July and showed signs of a more advanced position within Disenchantment Bay and Russell Fjord than in previous years. Are those ladies somewhat special? However, ice flow upstream of the dam was apparently still readjusting to changes in terminus boundary conditions with speeds and directions at or below uncertainty levels (<1–3 m d−1). Ask Karen M about Hubbard Glacier. http://moonbattery.com/graphics/obama-francis-on-board.jpg, “While the majority of tidewater glaciers in Greenland, Antarctica and Alaska are retreating, some are advancing. Geophysics, Mathematical The positive glacier-wide massbalance of Hubbard Glacier is directly measurable as changes in the overall surface alti-tude (thickness).Thesechangeswere measuredusinganair-borne laser altimeter system that has been described by Echelmeyer and others (1996).The resulting surface profiles havedatapointsevery1.5malong theflightpath,andaver- Answer to: Is the Hubbard Glacier growing? [53] We believe the key to the next closure is halting the process of submarine melting and mechanical calving as discussed above. Date of experience: July 2019. *How big is the Hubbard Glacier? In French cantons in Switzerland they still have archaic usage (septante, huitante, nonante (IIRC) for soixante-dix, quatre-vingt, quatre vingt-dix [70, 80, 90] Come to think of it Shakespeare is 16thC and it is, to some English speakers, almost unintelligible. Not in a decent journal. Global temperature is “resting” (see Monty python dead parrot sketch). Seasonal fluctuations in the advance of a tidewater glacier and potential causes: Hubbard Glacier, Alaska, USA. Hubbard Glacier . Thank Karen M . [42] The flow divergence increased flux east of Gilbert Point, which led to ice advance there and ice almost crossed the gap in August (Figures 4 and 7b). [45] Our bathymetric surveys show that following the 2002 outburst the channel was scoured to depths of 60 m by the outburst flood and ice advance. Plus even if its not warm enough to melt it, the acid oceans should make it fizz away and disappear. Hmm. The first bathymetry of the Gilbert Point area after the 1986 outburst was made 2 years later in July 1988 [Trabant et al., 1991]. She is pouring herself into Disenchantment Bay. Date of experience: August 2019. Source: CDApress.com. Also Taku Glacier the largest glacier in the Juneau Icefield doesn’t get any press, because it is advancing. We attribute these anomalies and the fact that 16 years elapsed between closures to submarine melting and mechanical calving driven by seasonal changes in water temperature and to a deep water channel. This would include Antarctica, Greenland, Arctic islands, South America and Alaska. Funny that the article didn’t reference this site: @Boulder Skeptic Increased rates occur about 13 hours after dam failure starts. Brett. Helpful. [11] The water level record for “Russell Lake” was obtained from the U.S. Geological Survey (USGS) who operated a standard water level type tide gauge located in the “lake”. A lot. Alaska’s Hubbard Glacier. The Battle for the Truth about Global Warming, “…invaluable” – Steven F. Hayward, The Weekly Standard, “…changed the world and is one of the most influential resources on global warming. With the terminus impeded and no longer free to simply slide forward, sliding was substantially reduced. The water was crystal clear like glass with many small pieces of ice all around. Any queries (other than missing content) should be directed to the corresponding author for the article. Discharge increased as erosion accelerated, with the moraine dam completely gone by 17:15 h. The inflection in the discharge curve marks an acceleration in discharge as water flow and ice calving began eroding the ice cliff, widening the outburst channel to 135 m. Discharge peaked at 55,000 m3 s−1 at about midnight with the lake draining to sea level by midday 15 August (Figures 5 and 6). The captain ofour ship, the Celebrity Millenium was great (a wonderful sense of humour). You could monitor it in real time. Growing again. /s. Hubbard Glacier is up to 65 meters (213 feet) wide at its face and 50 meters (164 feet) tall, but that’s only the tiniest piece of the ice: The main channel of this frozen river begins 122 kilometers (76 miles) back, pouring down from the shoulder of Mt. McKinley and Hubbard). [19] The first visible sign that closure was imminent was the emergence of proglacial sediment above water in front of the glacier terminus, visible on 2 May 2002. Fruitcake would be a good word to describe that thinking. See the About>Contact menu under the header. Ice upstream of the dam came within 10 m of the rock wall and threatened to also close the gap there. Not in any decent journal. WHOAAA!!! Wait for the warmies to actually argue that one, lacking the self-awareness to realise that they’re arguing the exact opposite behaviour on “retreating” glaciers. As far as your assertions on peer review are concerned. If the Hubbard Glacier cuts off the Russell Fiord and its level rises then it will become the poster child for sea level rise. In fact, there was no anomalously high rate of advance anywhere else along the terminus in 2002 that would suggest a surge. Their steady accumulation may eventually trigger the next closure. There are reports that its total mass is increasing. The outburst proceeded essentially in two stages: (1) relatively slow overtopping of the subaerial moraine and downward erosion at rates of 1–2 m h−1 with little amounts of lateral expansion due to ice calving, and (2) faster downward erosion of the submarine moraine (up to 7 m h−1) with a lateral expansion of the channel due to significant ice calving (∼7 m h−1). The Army Corp of Engineers’ Hubbard Glacier website for has some great photos of the advancing behemoth. [31] Our limited temperature record suggests ocean temperatures in EDB undergo a seasonal variation, particularly at 50 m depth (Figure 10). A PDF version of this report is available. Fireball in the sky over Alaska. See Glaciers growing in Spain (Pyrinees) Antarctica growing colder - Ice expanding 18 Apr 09 - "Ice is expanding in much of Antarctica," says this article. CAGW we’re waiting for you, Cheers It's possible that the glacier could close the fjord by later this summer if the current rate speeds up, says Harris. Dashed (solid) line shows glacier boundary from the first (second) photo date in each plot. Hubbard Glacier update: another closure of Russell Fiord in the making?. Ice was also threatening to close the ∼10 m gap behind the moraine dam. I think changing the last word follows their meme better considering how skeptics are viewed. I always wondered with all the talk about Global warming; we better took a look at it before it disappears. The advance runs counter to so many thinning and retreating glaciers nearby in Alaska and around the world. Late summer 2004 Russell Fiord water temperatures were comparatively uniform throughout the measured water column, averaging about 7°C. This tidewater glacier may be a bit of sleeping giant. Glacier and moraine boundaries from preceding photo are shown by dashed line. These rates are much lower than the typical 10–100 m h−1 reported by WO97. By 2002 the sediments had presumably become so shallow that the spring advance was able to push these sediments upward above sea level, thereby cutting off calving, and also forward onto and partially overriding the sill during the closure (Figure 8). The subsequent outburst in October 1986 is the largest outburst flood on record, achieving nearly twice the highest peak flow of the Mississippi River [Mayo, 1989]. The total age of the glacier is approximately 400 years. My goodness. Now about 66 km (41 mi) in length, it is the longest glacier in the southern hemisphere outside of Antarctica. This acceleration resulted in strong extensional strain rates, which probably fractured and weakened the ice, thus contributing to the calving collapse and channel widening during and following the flood. Weather, not Climate. “Understanding Hubbard’s behavior is scientifically interesting,” Stearns said, “but it also has immediate consequences for the town of Yakutat.”. The region adjacent to Gilbert Point, where the closure would occur, advances more slowly because seawater passing through the gap constantly erodes the ice. During the intervening years, glacier advance averaged only 6 m yr−1 toward Gilbert Point [Ritchie et al., 2006], much less than predicted and much less than elsewhere along the terminus. On the Russell Fjord side, Trabant et al. The new system will also operate on the Iridium network versus the previous GOES system. Number of times cited according to CrossRef: Glacier Variations at Xinqingfeng and Malan Ice Caps in the Inner Tibetan Plateau Since 1970. Alas, her grandchildren will simply not know what ice is. The Hubbard Glacier is actually growing not receding as many other glaciers. THE WHOLE THING IS COMING DOWN! Oh dear, how sad, never mind! Photo by Bruce Molnia, USGS. [41] As the moraine moved forward and began colliding with Gilbert Point, the boundary conditions for upstream ice changed appreciably. Here’s later reports, I looked at the list of WGMS glaciers (the last 3 reports) included in the total glacial mass balances. Measurements were corrected to mean sea level datum and the accuracy of the manometer is ±0.003 m [Seitz et al., 1986]. Any chance you could provide a list of ‘decent journals’? St. Helens 15 May 08 – Inside the Mount St. Helens volcano "an unexpected phenomenon is taking place: a glacier is growing." New headline: If you are ever there take a camera with a panoramic function as it is very wide. Similar to Hubbard glacier is Brüggen Glacier in Chile in the southern hemisphere. Hubbard Glacier, Alaska: Growing and Advancing in Spite of Global Climate Change and the 1986 and 2002 Russell Lake Outburst Floods U.S. Geological Survey Fact Sheet 001-03 January 2003 by D.C. Trabant, R.S. I saw the glacier during a 2012 cruise. Instead, flood waters from intense rains rapidly eroded the dam and submarine sediments, widening and deepening the channel. This baby is a whopper. Post outburst bathymetry documented that the glacier advance and the flood eroded the channel to depths of 60 m at Gilbert Point (Figures 8c and 9). I believe proper form by the stasi is to use a battering ram for knocking and flash bag grenades to neutralize babies. The reef west of Gilbert Point probably helped to trap these sediments. Comparison of lake level rise 1986 versus 2002 from the USGS water level gauge in Russell Fjord (modified from [, The 2002 outburst hydrograph (solid curves). Lake height reached 15 m asl before intense rains caused lake water to overtop the moraine dam on 14 August 2002. The thing has been going backwards from the moment pakeha looked at it, and is no faster or slower now. 3 km3 of water flushed through the gap in a period of about 30 hours. [30] Late summer ocean temperatures in EDB were warm and similar for 2002–2005, and showed a positive gradient with depth, increasing from 6.5°C near the surface to as much as 10.4°C at depths of 50 m (Figure 10). Flow was also becoming more bifurcated to either side of Gilbert Point. See California Glaciers Growing Against odds, glacier grows in cauldron of Mt. The advancement or retreat of a glacier’s terminus depends on the snowfall that melts down or flows from its catchment basin. Sorry, your blog cannot share posts by email. [5] Heading on flanks of Mount Logan in Canada (5959 m), Hubbard Glacier covers an area of 3500 km2 and flows over 120 km to sea level where its 11.5 km wide terminus calves into Disenchantment Bay and Russell Fjord (Figures 1 and 2). Generally, the glacier has steadily advanced but has seasonal oscillations of 100–200 m. A more complicated picture presents itself around Gilbert Point, where the 2002 outburst flood substantially eroded the ice face and caused a local retreat. See Glacier grows in cauldron of Mt. Hubbard is one of the few glaciers that is actually growing. Steller sea lions and mercury. Although we do not discount seasonal changes in ice speed as contributing to seasonal oscillations of the terminus position, we believe that the threefold increase in seasonal submarine thermal erosion could also reasonably explain the seasonal changes in terminus through increased submarine melting and calving. Rather than mark it, I think they expect us to realise that the picture is “now”. Holding up “peer-review” as evidence of global warming is now just a disguised appeal to authority argument. ‘CAGW’ is a term invented by skeptics, and is not used by any scientists. It’s 10 years later, so where is the terminus now? The Hubbard Glacier ice margin has continued to advance for about a century. I was there in 2008 as well http://coalitionoftheswilling.net/?p=4484. “projections … should be viewed with skepticism.” Hubbard Glacier could permanently dam the entrance to Russell Fiord in as little as 10 years. In 1986, the glacier crossed this shallow region, closing off Russell Fjord in June [Mayo, 1988]. Hubbard Glacier, Alaska: Growing and Advancing in Spite of Global Climate Change and the 1986 and 2002 Russell Lake Outburst Floods U.S. Department of the Interior U.S. Geological Survey USGS Fact Sheet 001—03 January 2003 and Chemical Oceanography, Physical Although the 2002 closure was also well publicized and well documented by photos and additional observations, it has only been cursorily described in the scientific literature [Trabant et al., 2003a, 2003b]. This is consistent with results from WC96 who described outburst events lasting several days. We take the characteristic length to be ∼1 km, the approximate distance from the sill to Osier Island where the channel is the narrowest and currents strongest, and where past closures have occurred (Figure 8). The last “published” data on glacial mass balances was in 2011 when things were going their way. Additional evidence for seasonal warming at these depths comes from Reeburgh et al. Since measurements began in 1895, Alaska’s Hubbard Glacier has been thickening and steadily advancing into Disenchantment Bay. Although there are 16 glaciers in Glacier Bay National Park, none of them compare to the size of Hubbard Glacier. The last of these has implications for the future behavior of the glacier. Moraine height continued to increase through July, keeping pace with rising lake level. Commentary by Jeffrey Simpleton Given the current rates of sediment accumulation it may take another ten years for sediments to fill the gap to 1999 levels (Figure 9). Americans spell it ‘sk’, while we here in Britain, being completely and entirely sensible, spell it ‘sc’. Well, it’s proof of warming, of course : in this polar area it doesn’t meld ice, but it makes ice more fluid and advance quicker (instead of sticking to mountain flanks), hence the grow. This paper focuses on the 2002 event, when a strong spring advance pushed shallow submarine proglacial sediments against Gilbert Point, closing off Russell Fjord by late June. There needs to be a more comprehensive monitoring of “all” glaciers of the globe. Yes, the glacier is gliding downhill on a lubricating film of liquid water, presumably from melted ice. If this were retreating, I could google “Hubbard glacier,” and the first 50 or so article hits would be duplicate commentaries on the press release about global warming/climate change. Currently the ELA is located in a fairly steep area. Trabant et al. A pulse of cooler water at its edge let part of the glacier gain some mass. Within this short time interval ice flowing into EDB doubled in speed from 5–6 m d−1 to preclosure speeds of 11–12 m d−1 and flowed in a more westerly direction. Hubbard Glacier is nicknamed the “galloping glacier” because of its fairly rapid (for a glacier) descent toward Disenchantment Bay. Water level began rising in the newly forming “Russell Lake”. Why Hubbard Glacier, Alaska is Better. The picture is current, the yellow lines are historical. All water depths are given with respect to mean lower low water (MLLW) (the height of the lower of the two low tide levels over a tide cycle averaged over a 19‐year period), which is standard practice for bathymetric charts. The image shows a close-up of the glacier’s terminus on that day. However, sediments are slowly filling in the Gilbert Point gap behind an erosion resistant sill at a rate of about 4 m yr−1. The shoal moraine effectively shut down ice calving and narrowed the channel between Disenchantment Bay and Russell Fjord to 75 m. [20] The glacier advanced another 130 m through June, shoving the moraine against Gilbert Point in a series of imbricate thrusts and closed off the fjord entirely by mid‐June. Recent Surge Behavior of Walsh Glacier Revealed by Remote Sensing Data. The collision of an advancing glacier with a rock wall is a rarely witnessed event, much less documented and quantified. If this had occurred, thickening ice could have significantly increased the height of the dam, and possibly made it less susceptible to the ensuing August rain event. Planets, Magnetospheric And we’re still awaiting Anthony’s paper on data treatment. Archival NOAA charts [NOAA, 1984] show that the regions seaward of the Gilbert Point shoreline were very shallow in 1977, with water depths less than 2 m in places, and that the glacier terminus was within 50 m of these reefs (see also Figure 8a). The Hubbard Glacier is actually growing not receding as many other glaciers. Spring temperatures in EDB on 25 April 2003 were considerably cooler, averaging 5.4°C and show little change with depth. Geology and Geophysics, Physical And they drive on the wrong side too – well most of them. Photo by Bill Lucey, U.S. Forest Service. And don’t even get me started on their average weight! Figure 4 (10 August 2002) captures the full extent of the moraine and ice dam prior to the outburst. Just read the climate-gate emails for evidence that the peer review process is now horribly flawed in a number of formerly “decent journals”. Hubbard Glacier Calving, on July 4th 2006. This has been done several times with surface temperature records and the dummies bought it. Alaska’s Hubbard Glacier is advancing moving toward Gilbert Point near Yakutat at an average of seven feet per day. The Hubbard Glacier is actually growing not receding as many other glaciers. Observations and flood records from 2002 also allow us to develop and test a model of dam failure and outburst discharge [e.g., Walder and Costa, 1996; Walder and O'Connor, 1997]. http://nymag.com/scienceofus/2015/05/how-a-grad-student-uncovered-a-huge-fraud.html While Hubbard Glacier may behave independently of climate trends [Trabant et al., 1991], its flow dynamics suggest a strong correlation with seasonal forcings.”, Believe some of the worrisome shrinking glaciers are advancing again, but we don’t get the clarion reports on it like we did when they were melting back. ALASKA’S HUBBARD GLACIER IS STILL ADVANCING, BUT AT A SLOWER PACE. Journal of Geophysical Research, Earth Surface, 120. … Read more. Additional support was provided by the Geophysical Institute, University of Alaska. Open circles are measurements from this study. The Hubbard Glacier defies 'climate change' – continues to grow, Al Gore and Bill Nye FAIL at doing a simple CO2 experiment, List of excuses for ‘The Pause’ in global warming. Increased flux to the east caused ice advance with ice almost crossing the gap behind the moraine dam (Figures 4 and 7b). The terminus is grounded on a submarine moraine that lies about 90 m below sea level (bsl) in Disenchantment Bay and Russell Fjord [NOAA, 2000]. Picture it flowing, ever so slowly, along its 76 mile path from its source in Yukon, Canada. The glacier advanced 40 m toward Gilbert Point during May and early June, pushing submarine moraine sediments forward with shoaling visible along a 0.5 km arc of the terminus (Figure 3a). In addition, the Gilbert Point terminus has advanced 100 m or more in the spring, only to retreat during the summer, well before the gap could be breached. We saw the Hubbard Glacier while cruising on our Viking Orion cruise ship. OMG! Growing. [1991] predicted, rather than 16 years later. This is a list of glaciers existing in the United States, currently or in recent centuries.These glaciers are located in nine states, all in the Rocky Mountains or farther west. Snow that falls in the basin either melts or flows down to the terminus, causing Hubbard to steadily grow. The 2002 outburst scoured the channel to depths of 60 m. We suspect that sediments must again accumulate to a sufficient level before another closure can take place because deep water inhibits glacier advance due to the effects of calving and submarine melting. That’s exactly how the glacier has been moving towards the ocean. A simple model of the outburst indicates that moraine erosion rates were almost an order of magnitude slower than those reported by Walder and Costa [1996] for other earthen dams. 10 May 09 – This from climatologist Cliff Harris of the Coeur d’Alene Press. Since 2002 the annually averaged terminus position at Gilbert Point has remained nearly constant at about 350 m from Gilbert Point, despite the fact that the advance into Disenchantment Bay has continued at ∼ 30 m yr−1. (d) Channel depths 2 years after outburst. This is totally the opposite of what the disciples of your religion tell us… “our projections/predictions/models are DATA that must be viewed as hard truth of what will come to pass.” David C. Finnegan/CRREL Brent Ritchie contributed Figure 2. What a lie! They don’t include Hubbard Glacier, Alaska, Brüggen Glacier in Chile, (largest tidewater glaciers in the NH and SH), Peterman Glacier in Greenland. If ice thickness was on the order of 100 to 200 m in that area, local thickening rates could have been of the order of 0.35–0.70 m d−1. Post processing against a base station in Yakutat ensured positional accuracy of ±1 m or better. http://www.wgms.ch/gmbb.html, Gary, I think WGMS just changed their web address. So, while the glacier is growing, the ice sheet is still losing tremendous mass and contributing to sea-level rise. Hubbard Glacier, Alaska [electronic resource] : growing and advancing in spite of global climate change and the 1986 and 2002 Russell Lake outburst floods / [D.C. Trabant, R.S. Modelling outburst floods from moraine-dammed glacial lakes. (Miriam O’Brien aka slandering “Sou” from Hotwhopper, that means you.). Our analysis was restricted to the regions close to Gilbert Point covering an area of about 3 km2 (Figure 2). Sediments are slowly filling in the channel at a rate of about 4 m yr−1, and their steady accumulation may eventually trigger the next closure. The 2008/09 surge of central Yulinchuan glacier, northern Tibetan Plateau, as monitored by remote sensing. A tidewater glacier is one that flows into the ocean. Introduction [2] Hubbard Glacier, located near Yakutat, Alaska (), is the largest nonpolar tidewater glacier in the world and has advanced over 2.5 km during the last century.This advance has now brought the terminus close to Gilbert Point at the entrance to 60‐km‐long Russell Fjord ().Hubbard Glacier has dammed Russell Fjord twice in historic times, once in 1986 and again in 2002. We therefore computed the combined uncertainty separately for each velocity using error propagation. The image above, acquired by the Operational Land Imager (OLI) on Landsat 8, shows Hubbard Glacier on July 22, 2014. 1. Traveling by sea, cruisers experience the awe-inspiring sight of the towering frozen river of blue ice. [46] Between 1986, and 2002 the rate of glacier advance averaged ∼ 30 m yr−1 everywhere along the terminus except at Gilbert Point. Do we call this ‘CAGC [cooling]?’ /sarc, Ah the resident troll finally chimes in from under the bridge… [56] The discharge records for the 1986 and 2002 outbursts differ significantly and reflect differences in lake height ±26 m versus 15 m) and dam types (ice versus moraine). (3) What drives the seasonal changes in terminus position? Hubbard Glacier Calving, on July 4th 2006. Temporal and spatial changes in water depth reflect deposition or erosion of proglacial sediments, which in turn can lead to increased or decreased terminus stability. (2) What conditions and events precipitated the eventual closure in 2002? [15] Acquiring bathymetric data became a priority of our investigation in the aftermath of the 2002 event. Composition and Structure, Atmospheric Characterizing the surge behavior of Alakesayi Glacier in the West Kunlun Shan, Northwestern Tibetan Plateau, from remote-sensing data between 2013 and 2018. Thus we propose that future closures will depend in part on continued sedimentation into the channel at Gilbert Point. Water depth is thought to be a key factor in controlling tidewater glacier stability and calving rates appear to be at least partially a function of water depth [Post, 1975; Brown et al., 1982; Meier and Post, 1987; van der Veen, 1996; Motyka et al., 2003]. If you do not receive an email within 10 minutes, your email address may not be registered, The Army Corp of Engineers’ Hubbard Glacier website for has some great photos of the advancing behemoth. Really awesome! The Hubbard Glacier is actually growing not receding as many other glaciers. Boxed area roughly defines region of ice flow analysis. NASA image of the Day - The Advance of Hubbard Glacier This advance has now brought the terminus close to Gilbert Point at the entrance to 60‐km‐long Russell Fjord (Figure 2). (If it is thin, it can start floating and will not necessarily advance.). However, during the outburst, the sill remained intact, deflecting flow toward the glacier front, creating a deep channel there. [33] We solved the coupled equations (2)-equations (2)–(4) for B(t) and w(t) using the Matlab ODE solver. The discharge records for the 1986 and 2002 outbursts differ significantly and reflect differences in lake height (26 m versus 15 m) and dam types (ice versus moraine). ________________________________________ The magnitudes of uncertainties due to each of the previous factors vary as a function of the position of the feature on the photo. She can expect a knock on her door at 3 A.M. from the Climate Stasi. The aerial photos included the glacier terminus and were taken periodically from early May through August including during and immediately after the outburst flood. [40] The rapidity of ice flow adjustment to changing conditions at Gilbert Point is striking. Both of these things are bad in the dyspeptic world of alarmism. 3 km3 of water were released within 30 hours with peak discharge reaching 55,000 m3 s−1, 24 hours after the flood began. At Hubbard Glacier, water temperatures can fluctuate from as low as 3°C in early spring to as much as 10°C in late summer depending on water depth (Figure 10). [6] The time and width‐averaged glacier advance between 1986 and 2002 was 28 m yr−1 into Disenchantment Bay and 34 m yr−1 into Russell Fjord. The Hubbard Glacier is actually growing not receding as many other glaciers. SPAIN Glaciers growing in Spain (Pyrinees) 10 Jan 11 - El glaciar del Infierno (glacier of Hell) has advanced. The captain ofour ship, the Celebrity Millenium was great (a wonderful sense of humour). This is of critical concern to local residents as a future closure could produce overflow and flooding south of Russell Fjord, potentially damaging lucrative fisheries and village infrastructures. A Greenland glacier is growing. Part of Hubbard Glacier has been advancing into Disenchantment Bay for … It spans a whopping 76 miles long, 1,200 feet deep, 6 to 7 miles wide and 25 to 30 stories tall at its face. Here is the site, but the last several years I haven’t been able to see the daily updates on how close the glacier is to the point. Given that tidal corrections in the vicinity of Gilbert Point have likely changed somewhat over time since the 1999 NOS survey, overall uncertainties of our water depth surveys are about ±1.5 m. [18] Some studies indicate that ocean water temperatures can play a significant role in the mass balance and stability of a tidewater terminus through submarine melting [e.g., Walters et al., 1988; Motyka et al., 2003].
