Winter Sightings of Marine Mammals in Arctic Pack Ice

open access: yesARCTIC, 1987
There is limited information about the winter distribution of some arctic marine mammals. In February-March 1976 six species of marine mammals were sighted in the pack ice of Baffin Bay and Davis Strait. Hooded seals were sighted along the ice edge in February, but in late March adults with pups were seen.

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,

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.

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

Acoustically derived ice-fracture velocity in central Arctic pack ice

The Journal of the Acoustical Society of America, 2000
Sounds radiated by fractures in Arctic ice (called acoustic events) are used to estimate fracture velocity. Both speed and orientation are obtained by measuring Doppler shifts induced by source motion. Data from the SIMI experiment of 1994 in the central Arctic are used in the frequency window 10 to 350 Hz.

Elastic waves in Arctic pack ice

Eos, Transactions American Geophysical Union, 1954
Elastic wave propagation was studied in the Arctic ice pack, on the Beaufort Sea, the Arctic Ocean, and at near‐shore locations. Ice thicknesses varied from 0.1 to 2.1 meters and water depths from 1 ½ to 3800 meters. Values of the elastic constants were derived from the measured velocities of the longitudinal and shear waves and the density. Dispersive
