The moraine is the high bank of debris in the top left hand quarter of the picture. For more explanation, click on the picture. Glaciology (from the Franco-Provençal language: glace, "ice"; or Latin: glacies, "frost, ice"; and Greek: λόγος, logos, "speech" lit. "study of ice") is the study of glaciers, or more generally ice and natural phenomena that involve ice. Overview[edit] Areas of study within glaciology include glacial history and the reconstruction of past glaciation. Types[edit] There are two general categories of glaciation which glaciologists distinguish: alpine glaciation, accumulations or "rivers of ice" confined to valleys; and continental glaciation, unrestricted accumulations which once covered much of the northern continents. Alpine - ice flows down the valleys of mountainous areas and forms a tongue of ice moving towards the plains below. Zones of glaciers[edit] Movement[edit] Ablation Ablation zone
GLACIOLOGY Institute of Low Temperature Science, Hokkaido University GLACIOLOGY GROUP UNIVERSITY OF WASHINGTON Glaciology is the study of ice in the environment. Important components are seasonal snow, sea ice, glaciers, ice sheets and frozen ground. Glaciology at the University of Washington includes course curriculum and research related to all of these components of ice in the environment. Glaciological research at the University of Washington is carried out by faculty and graduate students in the Department of Earth and Space Sciences, Atmospheric Sciences, Quaternary Research Center and Applied Physics Laboratory. What is Glaciology? Glaciology is the study of ice in the environment. Examples are: hemispheric snow cover in winter, thickness of sea ice on the polar oceans, depth of frozen ground, volumes of glaciers and the physical and chemical properties in layers cored from ice sheets. The ice also affects climate. Because these ice components are only decimeters to meters thick, they can change on time scales as short as seasons and can influence climate at all time scales.
Russian Geographical Society - Moscow Centre Subglacial and Polar Microbiology Related Projects: 1. Arctic metagenomicsThe vast majority of Earth’s biosphere exists in permanently cold environments, including polar regions (14% of surface area) and deep ocean (90% by volume). By examining the gene content in metagenomic libraries, hypotheses regarding metabolic roles can be made; however, metagenomics does not allow the definitive assignment of metabolic function to a contig. 2. Lake Vostok, buried for at least 15 million years beneath approximately 4 km of ice that has prevented any communication with the external environment for as much as 1.5 million years, is an ideal system to study this question.

Glacier Research Projects | Cryosphere Climate Research Group A long-term observational study is now underway in the southern Alberta foothills, with ca. 400 backcountry weather stations expected to be in place by August 2005. The observational grid covers an area of ca. 200 km by 120 km, extending from the continental divide to the agricultural lands east of Calgary. The first phase of the Foothills Climate Array (FCA) will operate for 10 years in the foothills region. The primary objective is to characterize the spatial-temporal patterns of meteorological variability and to develop physically-based models of the controls of topography and surface environment on surface weather patterns. Insights from the FCA will be used to develop improved climate downscaling strategies, climate change impact assessments, and boundary-layer process parameterizations in mesoscale climate models. The FCA is funded by the Canadian Foundation for Innovation (CFI), the Alberta Science and Research and Investments Project (ASRIP), and the University of Calgary.
Spectacular ice caves photographed for the first time deep beneath Swiss Gorner Glacier By Alex Ward Published: 14:36 GMT, 21 November 2012 | Updated: 15:27 GMT, 21 November 2012 These spectacular ice caves deep below a Swiss glacier have been mapped, photographed and surveyed for the first time. A team of eight descended into the moulins – vertical shafts – below the Gorner Glacier near Zermatt in October. Their work inside the remarkable icy caverns will help researchers get a better understanding of glaciers and their rate of melting. Descending the depths: A team of eight climbed down the moulins - vertical shafts - in the Gorner Glacier near Zermatt in Switzerland Photographer Robbie Shone, 32, was part of the team. ‘Ice caves are more impressive “normal” caves. ‘We were the first group to map these moulins and because the glaciers move around 15 metres (50ft) a year - they change every year. The team had to abseil into the moulins because the entrances were often vertical shafts that were up to 65ft deep. The bright blue: The glaciers move about 50ft a year as they melt
Suddenly There's A Meadow In The Ocean With 'Flowers' Everywhere : Krulwich Wonders... It was three, maybe four o'clock in the morning when he first saw them. Grad student Jeff Bowman was on the deck of a ship; he and a University of Washington biology team were on their way back from the North Pole. It was cold outside, the temperature had just dropped, and as the dawn broke, he could see a few, then more, then even more of these little flowery things, growing on the frozen sea. "I was absolutely astounded," he says. "Frost flowers," he was told. Courtesy of Matthias Wietz They aren't flowers, of course. Jeff's professor Jody Deming believes that as the poles warm, there will be more and more of these meadows, because there will be more and more open sea that turns to thin ice in winter. Which is why it would be surprising to find anything alive in these things. ... what you get is about "one to two milliliters of water," Jeff told me. And yet, he says, when he and colleagues checked, they found each frost flower housed about a million creatures. Did that surprise you?
