  • Bias-Corrected Sea Ice Thickness from Satellite, Aircraft, and Subsurface Measurements

    The primary objective of this research is to construct a comprehensive bias-corrected sea ice thickness record and use it to better quantify and understand the dramatic changes that have been observed in the Arctic ice pack. To do this all available Arctic sea ice thickness observations will be integrated, from satellite, aircraft, and subsurface measurements, and used to identify and correct systematic errors through comparisons with a common reference. With the resultant record four science questions will be answered:• What are the systematic differences between different measurement systems for sea ice thickness?• What are the spatial patterns in the trends…

  • Climate Change, Sea Ice Loss, and Polar Bears in Greenland

    This project aims to understand and quantify the effects of sea ice loss on polar bears in East and West Greenland (Baffin Bay).  Longitudinal (cross-time) comparisons of movement behavior and habitat selection will be driven by an analysis of a multi-decadal satellite telemetry dataset on polar bear movements in Baffin Bay and East Greenland, beginning when sea ice concentration and break up date started to decline (1991-1997) and encompassing present day conditions (2007-2013).

  • Polar Science Weekend

    Polar Science Weekend is four days of hands-on activities, live demonstrations and exhibits presented by scientists who work in some of the most remote and challenging places on earth.  Polar Science Weekend is supported by a generous grant from NASA.
