Welcome to the Sea Ice Experiment - Dynamic Nature of the Arctic (SEDNA) website.
SEDNA is a international collaborative effort to improve understanding of the interaction between sea ice dynamics and Arctic climate.
Whats happening in the Beaufort Sea now?
Check out the location of the SEDNA buoys here.
The VIMS lab at the university of Delaware, in collaboration with the National Ice Center is producing near real time motion analyses combinding RADARSat synthetic appeture radar (SAR) and buoy data. The most recent product is displayed here and here.
Most recent synoptic analyses are avialable for Alaska and the study region at these links from the National Weather Service and National Center for Environmental Prediction:
We are tracking the position of all of IARC's GPS buoy arrays (uploaded daily) in the Beaufort Sea. Six of these buoys where deployed in August 2006 as part of SITII, an NSF funded project. We are using their drift and SAR imagery to track current ice conditions in preparation for our Spring 2007 field campaign. Twelve buoys are currently being deployed at the APLIS camp in support of the SEDNA field experiment.
