hubbard glacier growing

I was there in 2008 as well http://coalitionoftheswilling.net/?p=4484. Isn’t that how climate-science-by-press-release works? Hubbard Glacier, glacierresearch.org. If you condemn peer review in general, you reject the modern day findings of all science, not just AGW. The seal who gave birth on a small chunk of ice right before our eyes did not seem too surprised that the glacier had not melted away. Here. Rather than mark it, I think they expect us to realise that the picture is “now”. Everyone else is… This happened roughly 13 hours after the start of the outburst. Hubbard Glacier and Russell Fiord study area. Please note: The publisher is not responsible for the content or functionality of any supporting information supplied by the authors. – Fred Pearce The Climate Files: Where glaciers meet water: Subaqueous melt and its relevance to glaciers in various settings. SPAIN Glaciers growing in Spain (Pyrinees) 10 Jan 11 - El glaciar del Infierno (glacier of Hell) has advanced. Physics, Solar This glacier is also advancing – Ref: Morainal bank progradation and sediment accumulation in Disenchantment Bay, Alaska: Response to advancing Hubbard Glacier. The image shows a close-up of the glacier’s terminus on that day. The previous system was dependent on a high-powered radio link to Haenke Island, which required significant power to operate. Ask Karen M about Hubbard Glacier. Ice upstream of the dam came within 10 m of the rock wall and threatened to also close the gap there. The Hubbard Glacier is actually growing not receding as many other glaciers. ‘CAGW’ is a term invented by skeptics, and is not used by any scientists. Thank Karen M . and Paleomagnetism, History of Growing again. “Walk toward the fire. Hubbard Glacier is the largest of eight calving glaciers in Alaska that are currently increasing in total mass and advancing. Helpful. Alaska tidewater glacier terminus positions, 1948–2012. Instead we use an approximation to the observed widening of the channel, i.e., an initial blowout to a 60 m width and then a linear increase in B at the rate of 7 m h−1. With the barrier to basal sliding removed, the terminus ice immediately responded to these new conditions and quickly accelerated. November 06, 2020 . I believe proper form by the stasi is to use a battering ram for knocking and flash bag grenades to neutralize babies. 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]. [39] The calculation of k was done with a smoothed water level record to avoid too much noise in dw/dt and particularly in d2w/dt2. November 13, 2020 . Ice thickness increases to 800 m and bed depth drops to 400 m bsl at 3 km. Knowledge of water depths is also essential for assessing stability of ice dams because ice flotation can trigger subglacial release of jökulhlaups [Björnsson, 1992, 2002; Roberts, 2005]. Figure 7c thus captures the major reorganization that ice flow underwent during this 2‐day period in response to the rapidly changing conditions at Gilbert Point. Alaska’s Hubbard Glacier is advancing moving toward Gilbert Point near Yakutat at an average of seven feet per day. The moraine has been squeezed up against Gilbert Point, increasing in elevation to 14 m asl. [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. ‘Peer-reviewed’ distinguishes scientists from those that aren’t but think they are. And isn’t Antarctica itself a giant glacier? 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. Our analysis was restricted to the regions close to Gilbert Point covering an area of about 3 km2 (Figure 2). Regions westward along the terminus into Disenchantment Bay lacked shoreline control necessary for photogrammetric analysis. Ha Ha, not Peculiar. Some material from contributors may contain additional copyrights of their respective company or organization. Journal of Geophysical Research: Earth Surface. Figure 4 (10 August 2002) captures the full extent of the moraine and ice dam prior to the outburst. The lateral extent of the 7 July 2002 ice and moraine dam (short‐dashed lines) is also shown. Anthony is co-author of peer reviewed papers. But Hubbard’s terminus is nearly 14 kilometers (9 miles) wide, and does not advance at the same rate across its entire width. Hubbard Glacier, located in southeast Alaska, has an intriguing history; it retreated during the Little Ice Age when neighboring glaciers advanced and is currently advancing while neighboring glaciers recede [Barclay et al., 2001; Trabant et al., 2003; McNabb and Hock, 2014]. [31] Our limited temperature record suggests ocean temperatures in EDB undergo a seasonal variation, particularly at 50 m depth (Figure 10). [25] By July, speeds decelerated by a factor of two or more throughout the study area: 5–6 m d−1 into EDB and 1.5 m d−1 toward Gilbert Point (Figure 7b). Perhaps I shouldn’t rush through an article on the way out the door. Upstream ice flow rapidly decelerated from 5 m d−1 to 1.5 m d−1 and flow diverged to either side of Gilbert Point. Solid circles are from, Schematic geometry of the outburst dam with (a) the moraine above sea level and (b) the moraine below sea level. Yellow lines indicate the location of the terminus on August 1, 1978, and on July 13, 2002. The article doesn’t mention the Hubbard is the largest tidewater glacier in North America. ↑National Park Service: Hubbard Glacier: Geology in Action! With CO2 rising weve seen a general greening of the planet and record harvests. David C. Finnegan/CRREL Landsat image of terminus position of Hubbard Glacier on 1 October 2000. 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. I’ll throw in just one example of broken science peer review and how it manifests itself as well to support my comment further, for good measure… Hubbard Glacier remains an ongoing study of calving glacier dynamics for the scientific community. Three questions arise from these observations: (1) What conditions prevent the glacier at Gilbert Point from advancing as rapidly as elsewhere? Stearns cautions, however, that these closure dates are “projections based on our current observations, and should be viewed with skepticism.” Antarctica has approximately 95% of all the freshwater ice in the entire globe…. The ‘formal’ excuse is that melting surface water reaches the base of the glacier through moulins and lubricates the flow causing the glacier to advance and thin. In May 1986, the Hubbard Glacier advanced into the sea, blocked the entrance to the Russell Fjord and hence formed Lake Russell. CAGW we’re waiting for you, Lake level rose at a relatively steady rate of about 0.2 m d−1 during water impoundment but three days of intense rain beginning on 12 August accelerated lake level rise to ∼1 m d−1 (Figure 5). If you’re wondering what the largest glacier in Alaska is, you got it. Part of Hubbard Glacier has been advancing into Disenchantment Bay for … Dashed (solid) line shows glacier boundary from the first (second) photo date in each plot. And would it be better if gays were reinforced instead? The image below, acquired on July 13, 2002 by the Enhanced Thematic Mapper Plus on Landsat 7, shows the glacier the last time that it sealed the fjord. Awaiting the new discovery of the properties of ice being made more flowy by warming. 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]. Thick line (A–B) near midchannel on Figures 8b, 8c, and 8d marks cross‐section location for, Bed profiles taken along the channel of maximum depth west of Gilbert Point where all surveys had adequate data (line A–B in, Water temperatures in Disenchantment Bay and Russell Fjord. Can’t they just blow up Gilbert point and save the fishing industry? Photo by Bruce Molnia, USGS. U.S. Geological Survey (2002, June 18) Advancing Glacier Coming Close to Blocking Fiord Near Yakutat, Alaska. It’s also been very active in the past, having had two major surges in the past 30 years. The moraine was 5 m (asl) high and formed a 50 m wide dam at Gilbert Point by 7 July 2002 (Figure 3b). Brent Ritchie contributed Figure 2. A smaller ship, we could get quite close and see and hear ice calving. Objects, Solid Surface Working off-campus? Hubbard Glacier, one of the few growing glaciers in Alaska, advances toward Gilbert Point north of Yakutat in summer 2009. However, during the outburst, the sill remained intact, deflecting flow toward the glacier front, creating a deep channel there. It’s not stopped,it’s stunned. I always wondered with all the talk about Global warming; we better took a look at it before it disappears. Bruce. *How big is the Hubbard Glacier? Hubbard Glacier, Alaska: Growing and Advancing in Spite of Global Climate Change and the 1986 and 2002 Russell Lake Outburst Floods. /sarc 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. Seasonal variations of up to 200 m have been also been observed. Hubbard Glacier: Growing not Shrinking - See 659 traveler reviews, 1,105 candid photos, and great deals for Alaska, at Tripadvisor. That’s not what the guy on the cruise said. Obviously, the lateral expansion of the channel was determined by ice calving rather than melting. Snow that falls in the basin either melts or flows down to the terminus, causing Hubbard to steadily grow. 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). The Hubbard Glacier is actually growing not receding as many other glaciers. See Alaska's Hubbard Glacier advancing 7 feet per day! Wildlife at Hubbard Glacier The edges of the iceberg (technically, bergy bits) are a great place for animal sightings. The Hubbard Glacier is the largest tidewater glacier in North America. The depth sounder was calibrated in situ against known water depths. In terms of a closure, the advanced position of the glacier around Gilbert Point indicates that if a closure is to occur in the future the mechanism will be significantly different than previous closures (1986, 2002).” THE HUBBARD GLACIER CONTINUES ITS ALARMING RETREAT – MORE EVIDENCE OF VERY-SCARY GLOBAL WARMING! [14] Uncertainties in our velocity calculations are due to uncertainties in the estimates of feature elevation (±15 m), resolution of position (±0.5 to 3 m), and uncertainties in adjustments for differences in photo scale and orientation between photo sets. Our post 2002 outburst bathymetry showed the existence of a shallow erosion‐resistant sill west of Gilbert Point (Figure 8). 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. It’s a magnificent sight in any case. Not surprising – that part of NZ gets past 25C in summer which tends to have an effect on ice! Such surges or other flow instabilities can temporarily increase ice velocities of the main trunk glacier, and Mayo [1989] suggested that the 1986 closure may have been triggered in part by a weak surge of the Valerie tributary. 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. Gilbert Point – The Automated Laser ranging system at Gilbert Point was replaced in late August with a new updated system. Recent Surge Behavior of Walsh Glacier Revealed by Remote Sensing Data. The proglacial moraine was being pushed forward uniformly at about 4 m d−1, nearly identical to terminus ice flow at this location. These measurements were primarily made in eastern Disenchantment Bay (EDB). Variations of erosion rates on shorter timescale cannot be expected to be resolved with this method. Please check your email for instructions on resetting your password. [43] In the 10 day period following the outburst, upstream ice speeds increased to predam levels and flow generally returned to its predam pattern of flow. [4] In this paper we describe Hubbard Glacier; discuss the formation of the 2002 dam and the subsequent outburst flood; analyze the changes in ice flow patterns caused by this event; show changes in bathymetry in and around the point of dam formation; present a discharge model for the outburst flood; and finally discuss how channel depth and warm ocean temperatures may be preventing the glacier from readvancing and closing Russell Fjord since 2002. A tidewater glacier is one that flows into the ocean. The captain ofour ship, the Celebrity Millenium was great (a wonderful sense of humour). Measurements were corrected to mean sea level datum and the accuracy of the manometer is ±0.003 m [Seitz et al., 1986]. The Hubbard Glacier is actually growing not receding as many other glaciers. The Hubbard Glacier is the most famous growing glacier. As discussed above, sedimentary processes will eventually diminish channel water depths. The advance runs counter to so many thinning and retreating glaciers nearby in Alaska and around the world. 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.

Imaging evidence for Hubbard Glacier advances and retreats since the last glacial maximum in Yakutat and Disenchantment Bays, Alaska. Photo dates and times are known to within a minute and therefore uncertainties in Δt are negligible. A smaller ship, we could get quite close and see and hear ice calving. This long‐term advance has a strong seasonal cycle with advance in winter to spring and retreat in summer to fall with oscillations as large as 100 to 200 m [Trabant et al., 1991; Ritchie et al., 2006]. We also obtained the NOS 1999 survey data (http://www.oceanservice.noaa.gov/dataexplorer/) surrounding Gilbert Point and derived a bathymetric baseline to compare to post‐2002 outburst data. 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). CRAZY BIG AVALANCHE @ 2:03 !! The flood waters rapidly eroded sediments and ice causing the channel to widen to 230 m and deepen to as much as 60 m bsl. Most are getting smaller, fast. A lot. There needs to be a more comprehensive monitoring of “all” glaciers of the globe. These concerns all seem so silly. [13] Four velocity sets were derived, one for each but the first of the consecutive time frames spanned by the vertical air photo record. 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. 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. Given the current rates of sediment accumulation it may take another ten years for sediments to fill the gap to 1999 levels (Figure 9). Any queries (other than missing content) should be directed to the corresponding author for the article. Lake height reached 15 m asl before intense rains caused lake water to overtop the moraine dam on 14 August 2002. Will Trump send the Paris Agreement to the US Senate? Their steady accumulation may eventually trigger the next closure. Also Taku Glacier the largest glacier in the Juneau Icefield doesn’t get any press, because it is advancing. Terminus and moraine boundaries were derived from all photo sets. 3. Source: CDApress.com. (There are also reports that it is loosing mass). Or dig a canal to bypass Gilbert Point? [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”. Oh dear! After 1986, the channel gradually filled in with sediments derived from glacier erosion and remobilization of sediments by glacier advance. Water levels to rose 0.24 meters (0.8 feet) per day. I think changing the last word follows their meme better considering how skeptics are viewed. 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 … 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. For permission, contact us. This divergence was visible at least 1 km upstream from the terminus. Save the Great British Bakeoff. We used a narrow beam (6°) 1 kW depth sounder to measure water depths in the vicinity of Gilbert Point on 23 August 2002, 9 days after the outburst started and then annually in late summer through 2005. From Wikipedia: warrenlb, please try and compose a comment that doesn’t involve the words ‘peer reviewed’. 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. 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. I cannot verify that this was an official growth rate. In fact, there was no anomalously high rate of advance anywhere else along the terminus in 2002 that would suggest a surge. We would also like to thank following individuals for valuable field assistance: Jackie Lott (USNPS), By Valentine, Ned Rozell, and Michael Hekkers. Recent Posts. Increased flux to the east caused ice advance with ice almost crossing the gap behind the moraine dam (Figures 4 and 7b). The water was crystal clear like glass with many small pieces of ice all around. Geophysics, Mathematical This Glacier is actually advancing (growing, the only one that still is by the way) so don't be too mad about the people being excited for the ice falling While Hubbard Glacier is not known to surge, many of its tributaries do. Hubbard Glacier Pros. But – but if its a tidewater then how can it be advancing at the same time as the current terrifying rise in global sea level. @evanmjones just because there are enviro-wackos, that has nothing to do with the hundreds of professional Climate Scientists doing research and publishing. 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. 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. Lastly, understanding the dynamics in this region is important for assessing the factors facilitating another closure, the timing of the next closure, and the stability of any future dams. Post was not sent - check your email addresses! The 1986 event was the subject of several articles [Seitz et al., 1986; Mayo, 1988, 1989; Trabant et al., 1991; Krimmel and Trabant, 1992] and received widespread attention in the press. It must be melting more at the top and running downhill, plus the extra humidity in the super-warm air causes more snow on the glacier. During the initial stages of 2002 dam formation, ice speeds and flow patterns were nearly identical to those reported for flow in this region for summer 2001 [Trabant et al., 2003a; R. M. Krimmel, unpublished data, 1990s]. I was on a cruise to this glacier in 2008 and we were told it was GROWING at 22 feet/day and that future cruises may be shortly banned from entering the bay due to the danger of the gap closing then breaking down, causing dangerous water flows. See Alaska's Hubbard Glacier advancing 7 feet per day! Planets, Magnetospheric 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 problem with your assertion dear Warren is that the scientists here advise the reader to view their projections with “skepticism”, which is the correction way to view projections. Ice calving had widened the channel to ∼230 m by the next day (Table 1 and see Figure 7d). It is the largest glacier on the northwestern edge of North America. (2015) Glaciological and marine geological controls on terminus dynamics of Hubbard Glacier, southeast Alaska. Just read the climate-gate emails for evidence that the peer review process is now horribly flawed in a number of formerly “decent journals”. let’s anticipate the alarmists response to this “dead parrot resting”: 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. 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. However, a 1‐km‐long, 300‐m‐wide submerged sill to the west of Gilbert Point appears on NOS 1999 bathymetry and persists on all of our post‐2002 outburst bathymetry (Figure 8). Enter your email address below and we will send you your username, If the address matches an existing account you will receive an email with instructions to retrieve your username. Hubbard Glacier is nicknamed the “galloping glacier” because of its fairly rapid (for a glacier) descent toward Disenchantment Bay. Surface ice velocities near Gilbert Point determined from vertical aerial photos: (a) 7 June to 7 July, (b) 7 July to 14 August, (c) 14–16 August, and (d) 16–23 August. I mean, come on, they are still using Farenheit! Not in a decent journal. OMG! Properties of Rocks, Computational A glacier arch in Argentina has collapsed - but it's not due to climate change. In May 1986, the Hubbard Glacier surged forward, blocking the outlet of Russell Fjord and creating "Russell Lake". Kind of like spending money to reinforce the dikes in New Orleans. Both of these things are bad in the dyspeptic world of alarmism. Holding up “peer-review” as evidence of global warming is now just a disguised appeal to authority argument. [57] The annual average terminus position at Gilbert Point has remained relatively constant since 2002 despite the fact that the rest of the terminus continues to advance at rates of ∼30 m yr−1. See the About>Contact menu under the header. – Jonathon Moseley, American Thinker, “…flashy (apparently widely distributed)”– Michael E. Mann, Material on this website is copyright © 2006-2019, by Anthony Watts, and may not be stored or archived separately, rebroadcast, or republished without written permission. The Hubbard Glacier is actually growing not receding as many other glaciers. The Hubbard Glacier had better get on board! Thus monitoring of both bathymetry and glacier dynamics is warranted. 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. I’ve known many of them professionally, in part when my Fortune 500 employer consulted with Scientists on Climate Issues, and your claims are wildly off base. Similar to Hubbard glacier is Brüggen Glacier in Chile in the southern hemisphere. (b) Channel depths from 1999 NOAA hydrographic survey. The last of these has implications for the future behavior of the glacier. Trabant et al. The gradient between terminus and up‐glacier velocities shows that the near‐terminus ice was being subjected to strong extensional forces during the outburst. Some good news from the thin ice. Sorry. No trends in severe weather. Furthermore, the glacier has an accumulation area that extends to very high altitudes and there are some indications of recent increased precipitation rates at high altitudes on nearby Variegated Glacier [Eisen et al., 2001]. The jagged curve is derived from lake level measurements, and the smoothed curve is the modeled discharge (. These soundings were sparse but suggest scoured depths exceeded 35 m. In subsequent years, the glacier likely modified submarine topography by remobilizing and excavating glaciomarine sediments, redepositing them in proglacial areas [e.g., Hunter et al., 1996; Motyka et al., 2006]. Alaska’s Hubbard Glacier is advancing moving toward Gilbert Point near Yakutat at an average of seven feet per day. Thus any changes blocking basal sliding would be immediately reflected in the surface velocity. We used the earlier chart as a basis of comparison for later changes. I would like to see a list of the largest tidewater glaciers in the northern and southern hemispheres which have been advancing or retreating and their total mass (length, depth and area). The glacier is approximately 7 miles wide at its foot and 76 miles long. The advance of Perito Moreno Glacier, a lacustrine calving glacier in Argentina, has periodically blocked a large tributary arm of the lake with dam failures there producing outburst floods that are reported to have released 3 to 4 km3 of water [Skvarca and Naruse, 2006; Stueffer et al., 2007]. Growing. Alaska's Hubbard Glacier advancing 7 feet per day! The region adjacent to Gilbert Point, where the closure would occur, advances more slowly because seawater passing through the gap constantly erodes the ice. We addressed this by smoothing the record with a Gaussian of half‐width 40 min. Perhaps the British spelled it with a ‘k’ 250 years ago? and Chemical Oceanography, Physical Currently the ELA is located in a fairly steep area. [1] Hubbard Glacier, the largest temperate tidewater glacier in the world, has been advancing since 1895 AD and has now twice dammed 60‐km‐long Russell Fjord, once in 1986 and more recently in 2002. Estimate of submarine melt rate in meters per day per degree Celsius above melting point as a function of water velocity based on equations from, By continuing to browse this site, you agree to its use of cookies as described in our, Journal of Advances U.S. Geological Survey (2010, December) Hubberd Glacier, Alaska. Hubbard Glacier, located in southeast Alaska, has an intriguing history; it retreated during the Little Ice Age when neighboring glaciers advanced and is currently advancing while neighboring glaciers recede [Barclay et al., 2001; Trabant et al., 2003; McNabb and Hock, 2014]. This moraine was pushed against Gilbert Point and by late June, closed off Russell Fjord. Spring temperatures in EDB on 25 April 2003 were considerably cooler, averaging 5.4°C and show little change with depth. There, the advance averaged only 6 m yr−1. Date of experience: July 2019. Outburst flood forecasting by monitoring glacier-dammed lake using satellite images of Karakoram Mountains, China. Glaciers growing on Glacier Peak, WA 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). Flow into Eastern Disenchantment Bay (EDB) averaged about 11–12 m d−1 and 4–6 m d−1 on the eastern side of the gap. [7] A sparse set of radio echo soundings (RES) in 1986–1988 showed the glacier to be about 360 m thick along the centerline with the bed at 180 m bsl at a distance of 1 km upstream from the terminus [Trabant et al., 1991]. It would be money well spent compared to the billions spent on “climate Change”. Flow was also becoming more bifurcated to either side of Gilbert Point. 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). But there's one image released this week by NASA that shows one Alaskan glacier that might actually be growing. These rates are much lower than the typical 10–100 m h−1 reported by WO97. WHOAAA!!! The loss of buttressing against Gilbert Point caused upstream ice to quickly accelerate (to 5 m d−1). With the terminus impeded and no longer free to simply slide forward, sliding was substantially reduced. NMFS vertical air photo mosaic of Gilbert Point dam (a) on 7 June 2002 and (b) on 7 July 2002. One weeps for humanity. The solution is simple: CHANGE THE RECORDS. The total age of the glacier is approximately 400 years. Global temperature is “resting” (see Monty python dead parrot sketch). [33] We solved the coupled equations (2)-equations (2)–(4) for B(t) and w(t) using the Matlab ODE solver. What a lie! But at least they found their way into the headline for this article. Funny that the article didn’t reference this site: Chinese Lunar Landing Mission Challenges US Space Supremacy, LIVE STREAM: Al Gore on using satellite data to measure climate change, Ottawa's latest climate plan bets on expensive and unproven carbon capture technologies, Robot probes the Red Sea’s carbon storage system, Data Sonification: A New Cosmic Triad of Sound, Roger Pielke Jr.’s 2020 Hurricane Season Recap, Ottawa’s latest climate plan bets on expensive and unproven carbon capture technologies, Polar bear habitat update for late November, Weekly Climate and Energy News Roundup #433, Intergovernmental Panel on Climate Change, National Oceanic and Atmospheric Administration. The general pattern for glaciers is south facing (north facing in the southern hemisphere) glaciers are retreating, while north facing glaciers are advancing. “… presumably from melted ice.” 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). Der Hubbard-Gletscher ist ein Gletscher in der Eliaskette im US-Bundesstaat Alaska und dem Yukon-Territorium Kanadas.. Photo by Bill Lucey, U.S. Forest Service. Our Yukutat, Alaska correspondent Frank "Skip" Ryman has updated his information for our readers concerning the advancing Hubbard Glacier that’s threatening the town where he’s the city manager. I suspect the last possible thing alarmists can cite will be long-term land-locked ice (still responding to little ice-age). [50] Figure 13 plots the results for the above equations and our assumed values and gives the estimated melting rates. Are those ladies somewhat special? Anyhow, for all the warnings about “proof of climate change” you look at where it was in 1850. I know French in Canada was 16th century French, although over the last two generations, modern French is being taught. The first bathymetry of the Gilbert Point area after the 1986 outburst was made 2 years later in July 1988 [Trabant et al., 1991]. March, and D.S. (2) What conditions and events precipitated the eventual closure in 2002? 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. “Understanding Hubbard’s behavior is scientifically interesting,” Stearns said, “but it also has immediate consequences for the town of Yakutat.”. Seismic stratigraphic evidence for glacial expanse during glacial maxima in the Yakutat Bay Region, Gulf of Alaska. A pulse of cooler water at its edge let part of the glacier gain some mass. 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]. As the summer season comes to an end and the Hubbard Glacier terminus has begun its seasonal retreat, we are busy putting the finishing touches on an exciting season of activity. The last “published” data on glacial mass balances was in 2011 when things were going their way. Open circles are measurements from this study. The Hubbard Glacier is actually growing not receding as many other glaciers. Lovely plumage! Variations in Alaska tidewater glacier frontal ablation, 1985–2013. 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 ellipses depict the estimated errors. 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. [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). This would include Antarctica, Greenland, Arctic islands, South America and Alaska. [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). Geology and Geophysics, Physical Who would have thunk it? See Glacier grows in cauldron of Mt. Moraine dam is shown in Figures 7a and 7b. Hubbard Glacier is defying the global paradigm of valley or mountain glacier shrinkage and retreat in response to global climate warming. The article appears to be another ‘alarmist claim’ that ice is growing and will block all ports. And don’t even get me started on their average weight! If you do not receive an email within 10 minutes, your email address may not be registered, Validation of high-resolution GRACE mascon estimates of glacier mass changes in the St Elias Mountains, Alaska, USA, using aircraft laser altimetry. With nowhere to drain, runoff caused the water level in the fjord to rise rapidly. Glaciers are slow-moving rivers of ice that usually grow in winter and shrink in summer. 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. http://nymag.com/scienceofus/2015/05/how-a-grad-student-uncovered-a-huge-fraud.html He said that’s all from climate change and then looked all spiritual in his eyes. St. Helens I believe your position is not intellectually tenable. Hubbard Glacier has dammed Russell Fjord twice in historic times, once in 1986 and again in 2002. Yellow lines indicate the location of the terminus on August 1, 1978, and on July 13, 2002. Feeble brains or dishonesty–take your pick. The findings, recently accepted for publication in the Journal of Geophysical Research, explain how the mechanics at the terminus override the influence of other climate fluctuations. However, d2w/dt2 is a numerical derivative that gets very noisy. [55] In 2002, a spring ice advance near Gilbert Point pushed shallow submarine proglacial sediments above water, isolating a 1‐km‐long section of the terminus from deep ocean water and strong tidal currents. [54] Complicating this prediction are ice flow instabilities. Ice was also threatening to close the ∼10 m gap behind the moraine dam. These speeds were quite high, ranging from 12 to 4 m d−1 in a N – S gradient Given that ice thickness within 1 km of the terminus was likely 200 to 400 m [Trabant et al., 1991], most (≥ 90 %) of the measured surface ice velocity must be attributable to basal sliding. [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. Really awesome! “It may be the only growing glacier in America - or maybe the world. Hubbard Glacier update: another closure of Russell Fiord in the making?. [27] Over the next 8 days following the outburst the strong extensional conditions rapidly diminished as upstream ice increased in speed (Figure 7d). Our examination of the 2002 event builds on these earlier studies and relies heavily on information gathered by a number of government agencies and private individuals as well as our own postoutburst investigations. A handful of Alaska glaciers are advancing and a few of those are getting bigger, but those are the exceptions. Americans spell it ‘sk’, while we here in Britain, being completely and entirely sensible, spell it ‘sc’. Tidal and seasonal variations in calving flux observed with passive seismology. Harbor seals ride the floes, basking in the sun; orca whales prowl just around the ice barrier, waiting for an unwary seal to come out to where the whales' sonar can reach. Haenke Island – The climate station at Haenke Island is damaged beyond repair and is scheduled for replacement. Photo about Hubbard Glacier showing growth layers and mountains in the background. 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. Love the expression ‘defies climate change’. 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. Don’t worry about what they call you.” – Andrew Breitbart | read more, “…the world’s most viewed climate website” From the paragraph immediately below the image: The image above, acquired by the Operational Land Imager (OLI) on Landsat 8, shows Hubbard Glacier on July 22, 2014. Based on the current rate of advance at the gap, Stearns estimated that closure could occur by 2043. The Army Corp of Engineers’ Hubbard Glacier website for has some great photos of the advancing behemoth. The thing has been going backwards from the moment pakeha looked at it, and is no faster or slower now. Roger Stearns, L.A. et al. On another note, when the authors used the phrase “should be viewed with skepticism “, did they use the “sk” word deliberately? Hubbard Glacier, Alaska: See 661 reviews, articles, and 1,110 photos of Hubbard Glacier, ranked No.9 on Tripadvisor among 890 attractions in Alaska. She is going home, to die. Hydraulic modeling of glacial dam‐break floods on the West Branch of the Susquehanna River, Pennsylvania. [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. She is pouring herself into Disenchantment Bay. The derived sediment erosion rates are quite robust with regards to the various parameters in equations (14a) and (14b). It has been growing and advancing over the past hundred years. 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. Water level began rising in the newly forming “Russell Lake”. Geophysics, Marine Based on the current rate of advance at the gap, Stearns estimated that closure could occur by 2043. Most are getting smaller, fast. Raw water depth data were corrected for tidal stages based on tidal corrections made during a NOS survey of the area in 1999. The image above, acquired by the Operational Land Imager (OLI) on Landsat 8, shows Hubbard Glacier on July 22, 2014. Outbursts of the magnitude seen in the past from Russell Fjord also constitute a severe hazard to navigation in the bay. Alaska's Hubbard Glacier advancing 7 feet per day! When you’re sailing towards Hubbard Glacier on a sunny day, the deep blue of its face looks like the blue of the furthest stars. September 2007. Figure 2. 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.” Related to Geologic Time, Mineralogy 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). 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]. This advance has now brought the terminus close to Gilbert Point at the entrance to 60‐km‐long Russell Fjord (Figure 2). And we’re still awaiting Anthony’s paper on data treatment. [46] Between 1986, and 2002 the rate of glacier advance averaged ∼ 30 m yr−1 everywhere along the terminus except at Gilbert Point. Norwegian glaciers. 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]. The flow vectors show strong N–S shear and prominent E–W compression toward Gilbert Point. I was co-author in one and working on another. Moraine height continued to increase through July, keeping pace with rising lake level. Hubbard Glacier, one of the few growing glaciers in Alaska, advances toward Gilbert Point north of Yakutat in summer 2009. [26] The time interval for vectors in Figure 7c spans only 2 days, from ∼1630 on August 14, during the peak of the outburst to ∼1630 August 16, only a day after the flood had dissipated.
