We propose to examine explicitly the role of glacier dynamics in determining glacial sediment yields through a combination of techniques from glaciology and marine geology.
		• Hypothesis: rates of glacial erosion are a function of sliding speed, and are therefore expected to diminish sharply as basal temperatures drop below the melting point. • To test this hypothesis, we will measure both sediment accumulation rates in fjords and dynamic characteristics of the glaciers producing the sediments, for six tidewater glaciers ranging from fast-moving temperate glaciers in Patagonia to slow-moving polar glaciers on the Antarctic Peninsula.
