Aircraft Observations of the Atmospheric Boundary Layer in the Vicinity of the Marginal Ice Zone Under Conditions of Flow Parallel to the Ice Edge
This paper describes aircraft observations made with the NOAA P-3 research aircraft on 24 March 1989. The measurement region was over the marginal ice zone, southeast of Spitzbergen, between 74 to 76 degs N and 19 to 27 degs E. Above the atmospheric boundary layer, the geostrophic wind was 12 m/s at...
