Summary: This licence has been issued for the scientific research application No. 5601. From 2017 – 2022, ABoVE airborne teams collected data across a wide variety of ecosystems in both the US and Canada. Depending on available funds, the team may re-fly one of the sensors to collect hyperspectral data at several locations in 2023. For 2023, the NASA Dynamic Aviation King Air B-200 aircraft with a h...

Summary: This licence has been issued for the scientific research application No.5577. The objective of this project is to better understand the physical, chemical, and biological controls of the Rapid Creek Formation by collecting and analyzing samples (through fieldwork) and developing a new sequence stratigraphic framework for the purpose of uncovering its potential and enabling the identification of...

Summary: This research will continue the long term objective of documenting and understanding the impacts of recent climate change on northern terrestrial and aquatic ecosystems. The short term objectives of my research for 2018 are: 1) to investigate the impacts of permafrost degradation and subsequent thaw slumping on freshwater ecosystems; 2) to examine the limnological implications of drained lakes on ...

Summary: The objectives of this research project are to: 1. map and assess changes in the distribution and composition of forest and peatland ecosystems due to climate changes; 2. estimate carbon storage (and variation) in boreal to arctic ecoregions of the Mackenzie valley; and 3. assess interannual and seasonal variations and key processes controlling carbon dioxide (CO2) and methane (CH4) dynamics. ...

Summary: The objective of this research is to study the impacts of climate change on boreal and aquatic ecosystems in the Mackenzie Delta region. By doing so, the researchers hope to gain a better understanding of the effects of long-term climate change on these ecosystems. Their study will utilize dendrochronological and paleolimnological methods to examine spruce forests and lake sites situated in the in...

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...

Licensed Year(s): 2007
Summary: The objectives of the Alaska-Canada Barren Lands Traverse is to: learn about changes in the Arctic from historical observations, to observe commercial and infrastructure changes in relation to how they compare and contrast to the impacts of a warming Arctic climate, and to compile baseline measurements of snow cover physical properties for validation of satellite datasets and snow cover chemical p...

Summary: The active layer, overlying the permafrost layer, is the surface earth material that thaws and re-freezes each year. Active layer thickness and character can influence hunting, fishing, forestry, gardening, transportation and construction. Changes in the active layer can contribute to landslides which may damage structures, hamper transportation, affect water quality, and influence surface and sub...

Licensed Year(s): 2006 2005
Summary: The main objectives of the field reconnaissance at landslide sites are as follows: o To visit landslide sites that exhibit on-going movement in order to qualify the rate of movement; o To identify main failure mechanisms and factors that contributed to slope failures; o To validate previous data collected through airphoto interpretation and remote sensing techniques; o To collect soil samples ...

Summary: The long term goal of this research is to develop a biogeochemical model for lakes in the Mackenzie Delta and a model for assessing the effects of stresses on rivers resulting from global change. This is year 13 of a 20 year program. Specific goals for this field season include: 1) investigating the sources and fates of dissolved organic carbon (DOC) in aquatic food webs of the Mackenzie Delta; 2)...
