APLIS 2007 Field Planning

The SEDNA field campaign includes several components. The field campaign has been designed to investigate sea ice stress - strain rate and redistribution relations at nested scales from the individual ridge scale, 1km, 10km, 100km to regional (seasonal ice zone in the Beaufort Sea) scales. The success of the experiment relies on deployment of the buoy array and collection of ice thickness data outlined in the cartoon below. As the experiment encompasses a large suite of data collection methods, we have split the field campaign in to modules that are managed by individual PIs. This set of modules, outlined in the links below, compliment each other. The data collection is designed to provide complete validation of sea ice stress - strain rate - redistribution models. Hence there are three themes in our field campaign: (1) stress and strain estimates for large scale ice motion, (2) a survey of the ice thickness distribution at all scales, and (3) a detailed investigation of a ridging event. The crux of the ice thickness survey campaign is to ensure that all thickness data collection is collocated with a set of calibration transects. Information about the resolution and accuracy of each ice thickness measurement method is outlined here. We will use near real time GPS buoy position, and real time GPS camp position to determine direction and distance along each transect line. Navigation code will be posted here as soon as it is available.
