Surface drifters in glaciated fjords

In collaboration with the Greenland Climate Research Center, Peter Winsor (UAF), Martin Truffer (UAF) and I are studying the fate and influence of glacial meltwater on fjord circulation. Since warming is a key driver of the observed acceleration and thinning of ocean terminating glaciers it is important to get a better understanding of the role that fjords play in ocean-glacier interactions. We use satellite-tracked drifters that can withstand collisions with ice blocks to measure salinity and temperature in the upper 15 m of the water column.
