Summary: Fundamental sea ice properties such as volume and surface characteristics change significantly within and between years. Arctic sea ice extent and thickness have undergone dramatic changes in the past decades. The strength of ice-albedo feedback mechanism depends on area-averaged ice concentration, snow and ice thickness and in summer significantly on melt pond fraction. The sea ice retreat in ...

Summary: The objective of this study is to provide information on the thickness distribution, movement, and characteristics of different types of sea ice within the Beaufort Sea Region. The focus will be on hummocked multi-year sea ice referred to as Extreme Ice Features (EIFs). These EIFs are poorly understood, and would be the most hazardous to any engineered structure in the southern Beaufort Sea (such ...

Summary: This project will establish a baseline climate-monitoring site in the perennial ice zone of the Canada Basin. Mooring carrying instruments to measure thickness of drifting perennial pack ice will be kept at Station A on the 3000-m isobath in the Canada B...

Summary: The base for operations is the PCSP Base at Tuktoyaktuk. The ice measurements are made by untended instruments operating beneath the sea throughout the year. The instruments to be retrieved in March 1996 were positioned in April 1995. They will be recovered through the ice using aircraft-based logistics. The survey of water properties will be conducted at about 15 selected sites in the offshore...

Summary: To carry out ice core drilling in Hobson's Ice Island; ice core drilling in multiyear sea ice attached to Hobson's Ice Island; measure ice thickness of Hobson's Ice Island; deploy satellite positioning buoys on ice islands....

Licensed Year(s): 1977
Summary: Studies on radio propogation, specifically on the skipping of radio beams: measurement of ice thickness, water salinity and water temperature at intervals of about 50 miles. Measurement of the concentration of ice nuclei in the atmosphere and ornithological studies....
