Summary: The objective of this project is to evaluate and compare complex and abundant lake ecosystems. This will be addressed through answering these 4 core questions: 1. Where, by how much and why Canadian lakes have changed during the last centuries? 2. How do taxonomic, molecular and biochemical features of planktonic, benthic and microbial communities change with lake alteration and which ones can...

Summary: The objective is to measure the age and stock of organic carbon derived from wildfires (fire-derived carbon) in the Mackenzie River region, and examine long- and short-term processes controlling the size and distribution of fire-derived carbon stocks in soils. The research team will measure fire-derived carbon stocks in soils and determine its age (radiocarbon dating) at four different location...

Summary: The objectives of this project are to understand the dynamics of large wood transport in the Mackenzie River and Delta by identifying the locations of wood sources and deposition, and quantifying the amount of wood that reaches the delta and the processes affecting wood transport. Using this knowledge, the research team can make estimates of carbon transport to the Arctic and improve global models...

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: This project aims to undertake fieldwork in the context of the PermASAR winter campaign. The data collected will support the evaluation and development of radar satellite Earth observation (EO) technology for application to the mapping of river and lake ice processes and properties. The research team expect the fieldwork to take place over a period of two to three weeks in the months of Februar...

Summary: The purpose of this project is to obtain baseline data for fish communities in Gwich’in Settlement Area (GSA) and Inuvialuit Settlement Region (ISR) lakes and use these data to predict future changes in fish communities caused by climate change. Specific objectives are: 1) to develop a baseline data set for fish populations, fish habitat, water quality, and water temperature for small and m...

Summary: For this project the research team will conduct the collection of microwave radar backscatter data of permafrost and boreal forest at wavelengths of 3cm (X-band), 6cm (C-band), 10cm (S-band) and 23cm (L-band). This process will capture two stable permafrost active layer states: thawed and frozen. The research team will derive information about permafrost (e.g. soil status, soil moisture) and about...

Summary: The objective of this sub-project are: 1) to continue assessing the performance of native plants which were seeded and transplanted into field plots in 2006 and 2007; and, 2) to establish two new field plots at the Inuvik golf course with the same intent of monitoring native seed performance in a disturbed habitat. The research team intend to collect data regarding winter survival, seedling e...

Principal Investigator: Kasook, Davonna C
Licensed Year(s): 2018 2017
Summary: The objective is to compare differences in snow depth, density and morphology of a heavily forested site and a tundra site. The Principal Investigator (PI) will investigate the effect landscape (forest vs. tundra) has on seasonal snow pack evolution and physical properties (density, temperature, snow grain morphology, and stratigraphy) of the snowpack. These results will be compared to historical ...

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 ...
