SEA ICE STUDIES ON MCMURDO SOUND DURING DEEP FREEZE 62

A study of thickness, density, and salinity of various ages of sea ice on McMurdo Sound, Antarctica was conducted during the summer season of Deep Freeze 62. During the sampling period, the 1- and 3-year ice decreased in thickness about 3 feet on the bottom; no loss occurred in the older 30-foot thi...

Description
Summary:A study of thickness, density, and salinity of various ages of sea ice on McMurdo Sound, Antarctica was conducted during the summer season of Deep Freeze 62. During the sampling period, the 1- and 3-year ice decreased in thickness about 3 feet on the bottom; no loss occurred in the older 30-foot thick ice. The sampling interval of 4 to 5 weeks at 3- to 5-fooh intervals was too great to permit the develop ment of summer trends in salinity, density and strength. Because of the lack of knowledge on the characteristics of Antarctic sea ice, further sampling of natural and flood produced ice in McMurdo Sound are planned by the Laboratory.
