Alaska Range
Alaska Range Introduction The heavily glacierized Alaska Range consists of a number of adjacent and discrete mountain ranges that extend in an arc more than 750 km long (figs. 1, 381). From east to west, named ranges include the Nutzotin, Mentas- ta, Amphitheater, Clearwater, Tokosha, Kichatna, Teocalli, Tordrillo, Terra Cotta, and Revelation Mountains. This arcuate mountain massif spans the area from the White River, just east of the Canadian Border, to Merrill Pass on the western side of Cook Inlet southwest of Anchorage. Many of the indi- Figure 381.—Index map of vidual ranges support glaciers.

Index glaciers range in size from tiny unnamed cirque glaciers with areas of less map modified from Field than 1 km2 to very large valley glaciers with lengths up to 76 km (Denton (1975a).

In diesem Sinne zählen die drei Feldkampagnen in der inneren Marguerite Bay und auf den South Shetland Islands, an denen ich in den vergangenen Jahren teilnehmen konnte, zu den großen und prägenden Erlebnissen. Die dabei vor Ort erworbenen Kenntnisse und erhobenen Daten bilden die Grundlage meiner hier vorgestellten Arbeit, auch wenn sie nicht unmittelbar in deren Mittelpunkt stehen. Im besonderen Maße möchte ich mich bei Herrn Prof. Dr. H. Goßmann für die Möglichkeit der Teilnahme an diesen Kampagnen und für die Betreuung dieser Promotion bedanken. Mit großer Geduld und einer Begeisterung für das Thema, die zeitweilig die meinige deut- lich überstieg, trug er mit seiner Unterstützung wesentlich zum Gelingen der Arbeit bei.

5. Structure and Dynamics of the Lambert Glacier-Amery Ice Shelf System: Implications for the Origin of Prydz Bay Sediments1
Barron, J., Larsen, B., et al., 1991 Proceedings of the Ocean Drilling Program, Scientific Results, Vol. 119 5. STRUCTURE AND DYNAMICS OF THE LAMBERT GLACIER-AMERY ICE SHELF SYSTEM: IMPLICATIONS FOR THE ORIGIN OF PRYDZ BAY SEDIMENTS1 Michael J. Hambrey2 ABSTRACT Depositional processes in Prydz Bay during the past 40 m.y. or so have been strongly influenced by glacier ice. Therefore, to understand these processes better, and to define the source areas of the sediment, it is necessary to deter- mine the role of the different ice masses entering the bay. Ice thickness, topography, and ice velocity data indicate that the Lambert Glacier-Amery Ice Shelf system is one of the most important routes for the discharge of ice from the East Antarctic Ice Sheet, and in the past has been the dominant influence on sedimentation in Prydz Bay. Most of the flow is concentrated through the Lambert Graben, which has been overdeepened to a depth of 2500 m below sea level. Glacio- logical work has indicated that close to the grounding line there is considerable melting, but from a short distance sea- ward of this position, basal freeze-on of ice of oceanic origin occurs. Thus nearly all the basal debris load in the Lam- bert Glacier system may be deposited close to the grounding line, and that there is probably negligible deposition be- neath the major part of the Amery Ice Shelf. Englacial debris, delivered to the open sea through the interior of the ice shelf, will be deposited from icebergs. There have been conflicting reports concerning the dynamics of the Lambert Glacier-Amery Ice Shelf system.

Chugach Mountains
Chugach Mountains Introduction The Chugach Mountains are a 400×95-km-wide mountain range that ex- tends from Turnagain Arm and Knik Arm on the west to the eastern tributar- ies of Bering Glacier, Tana Glacier, and Tana River on the east. On the north, the Chugach Mountains are bounded by the Chitina, Copper, and Matanuska Rivers. On the south, they are bounded by the northern Gulf of Alaska and Prince William Sound. The Chugach Mountains contain about one-third of the present glacierized area of Alaska (figs. 1, 2, 182) — 21,600 km2, accord- ing to Post and Meier (1980, p. 45) — and include one of the largest glaciers in continental North America. Bering Glacier is a piedmont outlet glacier with an approximate area of 5,200 km2 (Viens, 1995; Molnia, 2001, p.73) (table 2). The eastern part of the Chugach Mountains is covered by a continuous series of connected glaciers and accumulation areas (Field, 1975b). Several studies have characterized this region and adjacent regions as areas expe- riencing a significant 20th century retreat of its glaciers (Meier, 1984; Mol- nia and Post, 1995; Arendt and others, 2002; Meier and Dyurgerov, 2002). A study by Sauber and others (2000) examined the effect of this regional ice loss on crustal deformation in the eastern Chugach Mountains. Recogniz- ing that the range of annual thinning of glaciers in this region ranges from 1–6 m a–1, they calculated that uplift in ablation regions of these glaciers ranges from 1 to12 mm a–1, the greatest uplift being located just east of the Chugach Mountains, in the Icy Bay region.

We have been encouraged to acknowledge the wisdom of our mentors, peers, post-docs and post-graduates along the journey, which has been a great pleasure. We feel we are nowhere near our final destination as yet - there are paradigm shifts occurring in the field of glacier biogeochemistry even as we write – and we hope that this is a stimulus for early career researchers who may read this manuscript. We further hope that the story of the origins of the study of glacier biogeochemistry that we narrate will capture your imagination, as it did ours, and that we can convince you that glaciers and ice sheets are important and dynamic components of the Earth system.

Spatial and Temporal Variability of Glacier Melt in the Mcmurdo Dry
Spatial and Temporal Variability of Glacier Melt in the McMurdo Dry Valleys, Antarctica by Matthew James Hoffman A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Environmental Sciences and Resources: Geology Dissertation Committee: Andrew G. Fountain, Chair Scott Burns Christina Hulbe Martin Lafrenz Glen Liston Alan Yeakley Portland State University © 2011 Abstract In the McMurdo Dry Valleys, Victoria Land, East Antarctica, melting of glacial ice is the primary source of water to streams, lakes, and associated ecosystems. To better understand meltwater production, three hypotheses are tested: 1) that small changes in the surface energy balance on these glaciers will result in large changes in melt, 2) that subsurface melt does not contribute significantly to runoff, and 3) that melt from 25-m high terminal cliffs is the dominant source of baseflow during cold periods. These hypotheses were investigated using a surface energy balance model applied to the glaciers of Taylor Valley using 14 years of meteorological data and calibrated to ablation measurements. Inclusion of transmission of solar radiation into the ice through a source term in a one-dimensional heat transfer equation was necessary to accurately model summer ablation and ice temperatures. Results showed good correspondence between calculated and measured ablation and ice temperatures over the 14 years using both daily and hourly time steps, but an hourly time step allowed resolution of short duration melt events and melt within the upper 15 cm of the ice. Resolution of short duration melt events was not important for properly resolving seasonal ablation totals.
