Summary: This licence has been issued for the scientific research application No.5155. The objective of this project is to complete on ice snow depth, ice thickness and composition survey along with collection under ice core water quality information. Sample locations from previous years are located using a handheld GPS. On ice snow depth is measured using a tape measure. An ice auger is used to pene...

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: Environment Canada plans to measure snow depth, snow density and snow water equivalent (water storage in the snowpack), as well as lake ice thickness and structure for comparison with microwave radiometer measurements. Researchers have started to use microwave data from satellites for assessing snow water equivalent (SWE). Field tests to investigate the use of microwave sensors indicate that SW...

Summary: This study monitors glacier health and climatic change in the high Arctic and is part of an ongoing program that began in the early 1960s. It is also part of a larger program studying climate change. The base camp is located at the Polar Continental Sh...

Licensed Year(s): 2002
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: Ice gauges are installed on river ice once the ice is strong enough to support researchers (20 gauges in the Mackenzie Delta and 15 gauges on Hay River). The gauges are read every 10 days to obtain total ice thickness, white ice thickness and snow depth. From these data, the rates of ice growth and decay can be calculated, and the approximate date of maximum ice thickness can also be determined....
