Summary: The observational platform will be a single aircraft, the Alfred Wegener Institute (AWI) POLAR 5, a modified DC-3 aircraft. Objectives of this project are to: 1. determine the actual state of the sea ice thickness distribution in the western Arctic and what are trends of the Sea Ice thinning; 2. characterize the actual sea ice thickness distribution and identify trends in the sea ice thickne...

Summary: The objectives of the research are: (1) measure the spectral properties (i.e. how light is absorbed and reflected) and biochemical constituents (e.g. chlorophyll, water, nitrogen, carbon) of arctic vegetation at the ground-level in various vegetation communities across the Western Arctic (e.g. low-arctic to high-arctic); (2) investigate the potential of using satellite based multi-angular imaging ...

Summary: The focus of this research is to better understand the distribution of underground ice in hydrocarbon development areas. By identifying how much ice there is, we want to study how oil/gas activities and climate change could affect the land. The reseracher plans to use non-destructive techniques like ground-penetrating radar to accomplish our surveys. March-April, 2010: plan is to conduct 1-2 we...

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: The climate and numerous field reports indicate that permafrost should be continuous in the Mackenzie Delta. However, the most recent permafrost map in the Atlas of Canada classifies the delta as having discontinuous permafrost. Yet, no extensive fieldwork covering the entire delta has ever been realized. Unfrozen conditions beneath the ground, near shifting channels, have been recognized by vario...

Summary: This study is an investigation of massive ice in granular deposits in the Mackenzie Delta area and northeastern North Slave region. The presence of massive ice in aggregate deposits results in resource management problems, particularly for the oil indus...

Summary: Arctic clouds are dominant on average covering 40 to 60% of the skies over the Arctic ocean. They exert a large influence on the radiation balance in the Arctic, where climate change effects are predicted and observed to be largest in the northern hemisphere. The FIRE III field project will use in-situ measurements obtained using instrumental aircraft, in combination with concurrent satellite dta,...

Summary: To continue a series of aerial surveys of reindeer rangeland. Some samples of soil and vegetation will be collectd. The objective is to set up and test various types of remote sensing techniques....
