Mark Wensnahan’s research interests are in science education outreach and sea ice remote sensing. Dr. Wensnahan is currently part of a project to produce a 49-year record of arctic sea-ice draft measured by U.W. Navy submarines. Dr. Wensnahan has also conducted research on the use of passive microwave satellite data for determining sea ice extent and thickness, and the associated fluxes of heat and mass. Dr. Wensnahan joined the Laboratory in 1998. In 1995 he graduated from the University of Washington with his PhD in Atmospheric Sciences. He also earned his MS and BS degrees from the University of Washington.
Sea Ice Thickness Estimates Obtained from Satellites Using Submarines and Other In Situ Observations
We compare the observations of arctic sea ice thickness estimates from satellites with in situ observations – collected by submarine cruises and moorings under the sea ice, by direct measurement during field camps, by electromagnetic instruments flown over the sea ice, and by buoys drifting with the sea ice – to provide a careful assessment of our capabilities to monitor the thickness of sea ice.read more »
