Examination of such cores, obtained at depths of up to 1000 feet, revealed much concerning the past climate, vegetation, amount of snowfall, and other features of the region.

Extractions: Glaciological research is focused on glaciers in Norway, Iceland and Greenland, because they are important in water power production, landscape formation and as indicators of climate change. There is a growing interest in knowledge about the snow- and ice-covered areas of the world and the role they play in global change and development. Variations in the amount of snow and ice and their relation to climatic change have especially attracted much attention recently. Objectives The main issues studied by the Glaciological Group are (i) measurement of mass balance and energy balance on glaciers in Norway and Greenland, (ii) glacier hydrological investigations of the internal drainage system of glaciers and snow using hydrochemistry and stable isotopes, (iii) mapping of surface change of glaciers using photogrammetric methods and radio-echo sounding of ice thickness, and (iv) measurements of ice movement to establish the relation between mass balance, ice movement and glacier change.

Extractions: Meteorology Home Search Office Phone Fahnestock, Mark mark@atmos.umd.edu Shuman, Christopher shuman@buggam.umd.edu A rapid expansion in measurements of the Earth's climate system has been made possible in recent decades by new and evolving technologies. This expansion of scientific observations has changed the focus of many earth science disciplines. It is no longer possible to view any part of the Earth system in an isolated context. As a result, efforts have become focused on complimentary, integrated use of data and models to investigate the complex interactions present in the system. Much of the polar work conducted at ESSIC , in concert with colleagues at NASA's Goddard Space Flight Center , will concentrate on the expansion of the use of satellite and in-situ data to understand recent trends in climate related to sea ice extent and concentration as well as ice sheet mass balance and dynamics. The evolving focus of ice sheet research has in large part been driven by enhanced satellite-based measurement capabilities; this will continue with the launch of ICESAT/GLAS and with new, higher resolution optical and microwave sensors such as MODIS and AMSR on the EOS PM-1 platform. Given these efforts, a greatly expanded knowledge of the role of polar ice in global climate - past, present, and future - is likely.

Extractions: The Fox and Franz Josef Glaciers cut through dramatic glacial valleys to flow into temperate rainforest. While many glaciers world-wide have been retreating, these glaciers still flow almost to sea level, making them unique relics of the last Ice Age. South-Westland lies in the path of a band of wind known as the 'roaring forties'. The weather that flows on to the West Coast is forced to rise over the Southern Alps, thereby cooling and dropping most of its moisture as rain and snow. This process causes approximately 30 metres of snow to fall on the neve, or catchment area of the glacier every year. Snow that is compacted on the neve forms blue glacier ice that is funnelled down the valleys of the Franz Josef and Fox Glaciers. This flows under its own momentum, forming these 'rivers of ice' which are easily accessible from the Waiho (Franz Josef) and Cook (Fox) river beds. Although much melt occurs from the surface of the glaciers at lower elevations (the ablation zone), this high snowfall continues to push ice down the valleys at very high rates. This is aided by basal sliding, caused by a layer of water beneath the glaciers, formed by the weight of the ice pushing against the valley floor. Both of these factors cause the Franz Josef and Fox Glaciers to have flow rates that are up to 10 times faster than most valley glaciers. The glaciers flow over large bedrock steps on the valley floors. This causes the ice to extend and break up, forming steep icefalls that are mazes of crevasses and pinnacles of ice. Spectacular views of this dramatic landscape are gained from short valley walks to the Franz Josef and Fox Glacier terminal faces, or by taking a guided walk on to the ice. Either option will provide any visitor with a unique glacier experience.

Extractions: Glaciology in Iceland By Patrick M. Colgan, Northeastern University Introduction Iceland has always been a place where glaciology is more than an academic subject. Unfortunately, Icelanders haven't received much credit for their early contributions to glaciology, probably because their scientific writings were not widely read. Nowhere else though, have a literate people lived in such close proximity to sea ice and ice caps as the Icelander has. Because of this, Icelanders possess a practical knowledge of glaciers, and many principles of glaciology were probably apparent to them several hundred years ago (Bj rnsson, 1988). The settler Thordur Illugi built his farm near the snout of Brei An outline of Glaciological research in Iceland 1200 A.D. to the present The following is a timeline of glaciological research in Iceland. Most of the material for this summary was taken from Bj rnsson (1988) and Bardarson (1971). - Saxo writes his Danish history in which he describes sea ice and ice caps in Iceland. This is the first written record of Icelandic glaciers. He also describes the movement of glaciers and how the bodies of people who fall into crevasses were later found melting out at the ice margin. This phenomena is reflected in an Icelandic expression, "The glacier delivers back what it takes." - Bishop Gudbrandur Thorlaksson creates the first map of Iceland to show ice caps and glaciers (see Figure 1).

Extractions: TROPICAL GLACIOLOGY GROUP INNSBRUCK UNIVERSITY HOME In the low latitudes, seasonal thermal conditions are highly homogeneous but the oscillation of global circulation features gives reason to a more or less pronounced seasonality in moisture advection and air humidity. Inter-annual variations in both amplitude and length of each season are marked. Analysis of modern glacier fluctuations as well as energy balance studies on tropical mountains indicate the strong impact of variations in air humidity on glacier ablation. Studying low latitude glaciers opens the view to a variety of climate variables and to a broad spectrum of scales.

http://www.maths.ox.ac.uk/~fowler/research/glaciology.html

Extractions: Possibly the most interesting dynamical phenomenon is the glacier surge, a relaxation oscillation typified by the behaviour of the Variegated glacier (see the description in Paterson's book, The Physics of Glaciers). Normally, people say surging is unexplained, but this is not quite right. You can explain surging behaviour via a multi-valued sliding law, and it is possible to obtain such laws from realistic theories of hard bed sliding (see my 1987 JGR paper, cited below). The outstanding problem here is to describe how the drainage transition is effected in a three-dimensional geometry. I think this is a major control on the size of the surge. For the other `type' of surging glacier, the sub-polar (or polythermal) Trapridge, thermally controlled and sliding over till, the overall mechanism may be similar, though the details would be very different. The situation looks a bit like the ice sheet surge theory developed by Doug MacAyeal (see also Fowler and Johnson 1995, etc.). At the large scale, ice sheet modelling is probably in quite good shape. At the small to medium scale, however, this is less obviously true. The apparent occurrence of massive surges of the Hudson Strait ice stream of the Laurentide ice sheet in the last ice age (causing Heinrich events) must depend on the interplay between basal sliding and basal drainage, and modelling this is still at a rudimentary stage. Nor is it clear how such drainage theories will be included in the next generation of large ice sheet models.
