In cooperation with the International Arctic Research Center (IARC) at the University of Alaska, NOAA@NSIDC is providing an access point and standard metadata for the Sea Ice Experiment: Dynamic Nature of the Arctic (SEDNA) project. The SEDNA data collection is unique in that several ice thickness data sets were inter-calibrated and coordinated with monitoring of the ice pack strain-rate (horizontal deformation) and measurements of internal ice stress. This experiment was designed to improve our understanding of the relationship between sea ice thickness and dynamics.
The NSIDC DAAC is pleased to announce that the DMSP SSM/I-SSMIS Daily Polar Gridded Brightness Temperatures data set has been updated to include data through 31 March 2011.

The Arctic Report Card gives a yearly summary of environmental conditions. At the first workshop to bring together contributors, editors, and NOAA@NSIDC collaborators, plans were made to widen the number of parameters covered—now they are mostly physical variables—and to strengthen the peer review process. The sea ice section of the Report Card makes use of the Sea Ice Index. Florence Fetterer attended as product lead and to promote the use of MASIE for tracking short term changes in sea ice.
