Ice Thickness Topography Study - Beaufort Sea.
Principal Investigator: Melling, Humfrey
Licenced Year(s): 1996 1995 1994 1993 1992 1991 1990
Summary: The ice measurements are made by untended instruments operating beneath the sea throughout the year. The instruments to be retrieved in March 1994 were positioned in April 1993 and will be recovered by aircraft. The sonars will be re-deployed at the same locations to continue observations for another year. The survey of water properties by a lowered probe to 1500 m depth of the seafloor will be c...
