Dynamics of Greenland’s glacial fjords
Glacial fjords form conduits between glaciers of the Greenland Ice Sheet and the North Atlantic. They are the gateways for importing oceanic heat to melt ice and for exporting meltwater into the ocean. Submarine melting in fjords has been implicated as a driver of recent glacier acceleration; …

Sedimentology and Stratigraphy of Glacial Lake Souris, North Dakota: effects of a glacial-lake outburst
<p>Glacial-lake outbursts commonly occurred along the southern margin of the Laurentide Ice Sheet as ice-marginal lakes suddenly drained. These outbursts released huge volumes of water with tremendous erosive potential, forming large trench-shape channels. Although glacial-lake spillways have been …

Climatic factors influencing Last Glacial Maximum and modern glacial conditions in the tropical and subtropical Andes
… Andes. Model results show average Last Glacial Maximum (LGM) equilibrium line altitude (ELA) depressions to be approximately 600 m in the tropics and 800 m in the subtropics, consistent with studies that suggest the subtropical Andes were glaciated at LGM. While previous studies have …

The late glacial and post glacial history of the Vale of Pickering and northern Yorkshire Wolds
… of these was to study the sedimentary data from glacial and pro-glacial deposits in the Vale of Pickering to assess their age and environment of deposition. The sediments were mapped in the field and analysed in the laboratory. A glacial outwash rather than lake-beach origin was proved for an …

Glacial Stratigraphy of northeastern North Dakota
… units (formations} composed dominantly of glacial sediment have been recognized in northeastern North Dakota. Three formations, the Falconer Formation (Harris and others, 1974}, the Dahlen, and Gardar Formations (Salomon, 1975). Have been previously recognized. Four formations, the …

Glacial stratigraphy of southeastern North Dakota
… lithostratigraphic units are recognized in the glacial sediment {till) of southeastern North Dakota. Five of these units are not formally named; eventually most of these units will be correlated with formations in surrounding regions. Two of these units, Gardar and Dahlen, are formations …

Glacial Geomorphology of southern Alberta, Canada
During deglaciation from the Last Glacial Maximum three terrestrial ice streams within the south western sector of the Laurentide Ice Sheet competed and coalesced in southern Alberta; the High Plains Ice Stream (HPIS), Central Alberta Ice Stream (CAIS) and the east lobe. The ice streams are …

Glacial geology of the Western Catskills
<p>Ic0 flow directions on the glaciated Appalachian Plateau in central New York were from the Adirondack Hountains. This is demonstrated by both striae directions and erratic provena..-1ce studies. No evidence for more than one Wisconsin glaciation as suggested by Rich (1935) could be found. …

Geological constraints on Neoproterozoic glacial episodes
Neoproterozoic glacial episodes are amongst the most intense glaciations that the Earth has experienced, and are associated with major changes in the Earth System, such as the breakup of a supercontinent, the evolution of complex multicellular life and extreme geochemical perturbations. A …

Suspended sediment concentration in Alpine glacial meltwaters
Suspended sediment concentration in meltwaters draining from Alpine glaciers vary considerably both diurnally and seasonally. In order to characterise sediment variability, sub-daily close-interval sampling measurements of suspended sediment concentrations are usually undertaken. In close-interval …

Identifying Glacial Meltwater in the Amundsen Sea
… ocean waters melting the ice from below. The glacial meltwater appears as a warmer and more saline water mass (with lower O2 concentration) than theWinterWater. Tracing meltwater pathways from ice shelves is important for identifying the regions most affected by the increased input of this …

Glacial-Interglacial Variability of Eastern Pacific Hydroclimate
