Abstract
A joint experiment between DRB and MOT in Norwegian Bay on Sept. 4 and 5, 1970 tested the ability of airborne infrared line scanners to differentiate first year ice from second year ice when the puddles were covered by six inches of bare ice. The scanner was not able to detect a difference in the radiation from the two types of ice in any of its spectral channels, and ground measurements of the radiation temperature, ice thickness, and profiles of temperature and conductivity confirmed that separation on the basis of radiation temperature could not be expected. However, textural differences in the imagery from variations in puddle size and density permitted areas of first and second year ice to be identified.
