Assessing glacier retreat and landform production at the ‘debris-charged’ snout of Kvíárjökull, Iceland
Iceland is a critical location for the study of glacier fluctuations and landform production in response to climate change due to its diverse glacial legacy and its archive of aerial photographs that provide accurately dated records of glacier retreat and landform evolution from 1945. This study …

Glacier retreat and projected river regime changes in the hydrologically highly-coupled Virkisjökull catchment, SE Iceland
Virkisjökull is an outlet glacier of the Öræfajökull icecap in SE Iceland and currently covers 60% of its catchment, though this is reducing. Fieldwork and catchment monitoring activities for this project over the last 4 years includes measurement of ice ablation, proglacial discharge, dye-tracing …

Spatio-Temporal Vegetation Change as related to terrain factors at two Glacier Forefronts, Glacier National Park, Montana
Glacier retreat is considered a clear sign of global climate change. Although a rich body of work has documented glacial response to climate warming trends, comparatively little research has assessed vegetation change in recently deglaciated areas. In this study, we assess vegetation change at two …

The Winds of Change: The effects of katabatic winds on fjord circulation, sea-ice export and glacier stability at Sermilik Fjord and Helheim Glacier
… changes in fjord circulation, sea-ice export and glacier terminus stability, but despite this few studies have investigated their wider implications. In period of rapidly retreating tidewater glaciers, katabatic winds are known to aid retreat indirectly, through inducing warm Atlantic origin water …

Storehouse of the Earth : to document the fast-changing environment
… problematic. The site of this thesis, the Rhone glacier and surrounding area, shows the drsatic speed of change. The Rhone glacier, 11,500 years old, is one of the oldest glaciers in the Alps. However, scientists estimate that this glacier, along with 94% others in the Alps, will disappear in 100 …

Seafloor geology, deglacial history, and early post-glacial evolution of eastern Juan de Fuca Strait
… to ice-distal depositional environment during glacier retreat. There is currently little sediment input to the strait, so most modern sediments consist of reworked glacial deposits that occur in banks and coastal exposures.</p><p>The strait was deglaciated rapidly; in about 100 years at a rate …

Controls on terminus change of marine terminating glaciers in Greenland over the last 40+ years
… dominated by the behavior of fast-moving outlet glaciers in Greenland. These glaciers are changing through melting of the terminus face and/or calving of icebergs; the combination of these processes and ice motion determines the position of a glacier terminus. In understanding how and why outlet …

Föhn winds on South Georgia and their impact on regional climate
… this has been an increase in the rate of glacial retreat throughout the last century, with glaciers on the northeast leeside of the island retreating at a faster rate than those on the southwest side. These asymmetrical changes are thought to be linked with the strengthening of the westerlies. If …

A Glacial Sedimentary System in Northwest Spitzbergen
… lakes in Signedalen, fed by three small cirque glaciers. Six further cores were taken from the fjord inlet, Signehamna, into which meltwater from the linked glacier-fed lakes and a further two glaciers drain. Signehamna drains into Lilliehookfjorden, which with Mollerfjorden, combines to form …

PLANT AND ARTHROPOD COMMUNITIES OF ALPINE ICE-RELATED LANDFORMS: ECOLOGICAL AND BIOGEOGRAPHIC IMPORTANCE
… glacial sites (Peirabroc, Clapier and Calderone glaciers) in peripheral mountain chains (Maritime Alps and Apennines, Italy, respectively). In these studies also important environmental parameters (e.g. debris thickness, soil temperatures and chemical parameters) have been correlated with …

Subsurface Geophysical Investigations of Oneida Lake Ny: Insights Into Ice Sheet Processes and Deglaciation At Termination I
<p>Reconstructing the retreat of the Laurentide Ice Sheet (LIS) provides insight into understanding end-Pleistocene climate, a critical set of boundary conditions prior to the onset of Holocene climates that were optimal for human dispersal and societal growth. Constraining ice sheet dynamics, …
