Summary

[edit]
Description

Part of the Arctic Ice Dynamics Joint Experiment (AIDJEX) Project, the Cold Regions Research and Engineering Laboratory (CRREL) and US Geological Survey (USGS) group measured mesoscale deformation of sea ice.

In the AIDJEX pilot study, scientists collected meteorological and oceanographic data from instruments located at the camps and on floating data buoys. The experiment was designed to collect coordinated measurements over at least one year, in order to have the right combination of data for understanding atmosphere and ice interactions. The submarine USS Gurnard participated by collecting ice draft data from upward-looking acoustical soundings (sonar). Ice draft (the depth of the ice below the water surface) is an estimator of ice thickness.

The AIDJEX project was the first major western sea ice experiment constructed specifically to answer emerging questions about how sea ice moves and changes in response to the influence of ocean and atmosphere. The pilot study in 1972 was followed by the AIDJEX field program in 1975 and 1976.
