West Antarctic Sea Ice Campaign
The West Antarctic Sea Ice Campaign includes passive microwave measurements of sea ice concentration from the ship Laurence M. Gold as well as aircraft-based measurements. The campaign began in Punta Arenas, Chile, and progressed to the Bellinghausen and Weddell Seas.
Dr. Konrad Steffen led the ship campaign, which monitored sea ice surface at various passive microwave frequencies to obtain brightness temperatures. The photograph at right shows graduate students Russell Huff and Nicolas Cullen from the University of Colorado as they make ice thickness validation measurements on small ice floes using an EM31 (electromagnetic induction) sensor. The photograph was taken by Dr. Steffen from a small boat that launched from the research ship shown in the background.
The West Antarctic Sea Ice Campaign was carried out from 14 August through 4 September 2003. The map in Figure 1 indicates the area that the ship study covered. Note the brown tip of South America on the left side of the map.
The aircraft-based campaign was headed by Dr. Joey Comiso 14 August through 15 September 2003. The aircraft study was to have encompassed a larger area than the ship campaign, as shown in Figure 2; however, mechanical problems forced cancellation of this part of the mission.
For more information, see Dr. Comiso's AMSR-E Sea Ice Parameters and Validation Studies (PDF ~8 MB).
