 Investigation of role of drifting / blowing snow in determining the accumulation and distribution of snow on sea ice.

Measurements include two major components:

(1) direct measurement of snow drift and accumulation, and

(2) detailed measurement of snow depth distribution.

The former includes temporary deployment of small meteorological towers on the ice at each station.  The latter includes intensive snow depth probing and laser scanning of the surface.  At 3 stations, autonomous platforms (“sams buoys”) will be deployed and left behind to measure snow accumulation.
