Sediment Flux in a Fiord/Shelf Transect of an Ice-Dominated Continental Margin.

Piston cores from fiords along the eastern margin of Baffin Island, NWT are being studied in order to compute variations in sediment flux on time scales of decades to thousands of years. Radiocarbon dates indicate that the sedimentation rates in outer basins range, on average, between 20-50cm/THAT&#...

Description
Summary:Piston cores from fiords along the eastern margin of Baffin Island, NWT are being studied in order to compute variations in sediment flux on time scales of decades to thousands of years. Radiocarbon dates indicate that the sedimentation rates in outer basins range, on average, between 20-50cm/THAT'S NUMBER: 1 (NOT ALPHA)ka. The cores extend back to ca. 10 ka, or earlier, and provide possible analogs for conditions around the present day Greenland Ice Sheet. Grain size, grain shape and mineralogical studies are being carried out in order to evaluate down fiord variations in sediment source and sedimentation processes.
