Because the ice thickness affects the dynamics of the ice, it was necessary in AIDJEX to confront the chaotic ice geometry.
Looking back, one wonders why the AIDJEX plan was not criticized more ruthlessly.
The objectives of the AIDJEX program were further exploration of the oceanic boundary layer and measurement of ice-water stress.
As AIDJEX was developing, one of the central questions was how best to represent the resistance of the ice to being deformed.
At the very beginning, the funding agencies made it clear that AIDJEX was a finite-duration study, and that we could not expect to see it "institutionalized" upon its completion.
It was another great coup of AIDJEX that it won participation by the U.
What we know is that, in subsequent years, the NSIDC distributed AIDJEX data to many users (see Pritchard, 1980 for an early summary of the results of AIDJEX).
Upward-looking sonar to measure the draft (thickness) of floating ice and the technology to deploy and recover instruments moored at the sea floor existed during AIDJEX, but they were not applied until 10 years later.
Observations during AIDJEX led us to believe that the eddies developed primarily by baroclinic instability of the shelf break circulation in the southern Beaufort Sea.
To test the idea that ice deformation changed the ice-thickness distribution in quantifiable ways, AIDJEX pioneered the idea of carefully measuring both the deformation and the changes in leads and ridges in sequential LANDSAT images.
