This thesis investigates lithogenic sediments on the Siberian Arctic shelf, their sources, modes of dispersal, transport pathways and post-depositional diagenetic alteration. Working with cores collected from the Chukchi, East Siberian and Laptev Seas, we characterize surface-sediment elemental chemistry and clay mineralogy. We identify five regions with endmember sedimentary compositions. Comparing...
The net mass balance fluctuations of Arctic and Sub-Arctic glaciers, north of 47.5°
North latitude, are described over a 45-year period from 1957 to 2002 using two
parameters derived from a gridded climatology reanalysis. Variability among 185
measured glaciers was represented according to two main components. The first
component represents...
The international council for the exploration of the seas (ICES) publish
annual reports on fish stock assessments. Based on the stock assessment
data for the North-East Arctic cod we estimate the effective fishing
mortality, establishing coefficients for the catchability-at-age and the
annual fishing effort. The fishing effort estimates are then...
A major achievement in research supported by the Kluane Lake Research Station was the recovery, in 2001–02, of a suite of cores from the icefields of the central St. Elias Mountains, Yukon, by teams of researchers from Canada, the United States, and Japan. This project led to the development of...
Since most wolf (Canis lupus) diet studies have been conducted in inland ecosystems, comparatively few data are available on diets of wolves in coastal systems. We investigated the diet of wolves in Glacier Bay, Alaska, from 12 May to 28 June in both 2010 and 2011. Although we identified 12...
