Upwelling: Oceanic Structure at the Edge of the Arctic Ice Pack in Winter

Science, 1979
Observations taken on an expedition into the Arctic Ocean north of Spitsbergen indicated the existence of a region of wind-driven upwelling along the edge of the ice pack. Models underestimate the 12-kilometer width of the upwelling region.

HF radar observations of Arctic pack-ice breakup

IEEE Journal of Oceanic Engineering, 1986
This paper describes the first reported high-resolution remote measurements of sea-ice velocities during the summer Arctic pack-ice breakup, made with a high-frequency (HF) radar system (CODAR, for Coastal Ocean Dynamics Applications Radar) located on Cross Island, Alaska. Each 36-min observation also gives the positions of the ice edge, the moving ice,

Airborne laser profiling of the arctic pack ice

Remote Sensing of Environment, 1971
Abstract Since 1964, airborne experiments over the Arctic pack ice have been conducted, on an opportunity basis, to test and evaluate the usefulness of various remote sensing systems for mapping and measuring sea ice conditions and features. This paper describes the results of an analysis of laser terrain profile data obtained with coincident ...

Transport measurements in the arctic ice-pack

Letters in Heat and Mass Transfer, 1980
Abstract The characteristics of the Polar Pack are generally thought to have a large influence on terrestrial weather. Yet the environment of the sea ice and its dynamic response to the seasonal cycle, as well as to gradually changing average conditions, have received little study or transport modelling. A specific measurement program was devised and
