About The Product

Published by way of the yankee Geophysical Union as a part of the Antarctic study Series.

In a 1971 medical Committee on Antarctic study document that reviewed polar contrasts in sea ice, Lyn Lewis and Willy Weeks made the next statement: "People who examine sea ice within the Arctic Basin are frequently asked in the event that they have ever studied ice in Antarctica, and so they solution 'why trouble, it is the usual stuff." Noting this was once "fortunately precise to a substantial extent," they further "It is apparent that destiny paintings will rely severely at the logistics amenities on hand to permit floor observations past the quick ice part in any respect seasons of the 12 months. of just about equivalent value would be the improvement of tools and recording apparatus suited to use within the polar setting" (Lewis, E. L., and W. F. Weeks, Sea Ice: a few Polar Contrasts, in, Antarctic Ice and Water Masses, edited via G. Deacon, medical Committee on Antarctic learn, Cambridge, 23-34, 1971).

Lewis and Weeks made no particular point out of Earth-orbiting satellites, on which the 1st passive microwave sensor turned operational in December 1972. below a 12 months later the enormous Weddell Polynya was once saw for the 1st time. might be greater than the other improvement, this unforeseen function illustrated the capability to tremendously extend our wisdom of sea ice throughout the software of spaceborne distant sensing. at the same time, it acted as a catalyst for an important raise within the point of study.
