Summary:
The objective of the fieldwork is to collect soil samples from the active layer and near-surface permafrost. Twelve samples will be collected from coastal bluffs at Crumbling Point, and six samples from river banks beside East Channel.
Soil profiles 1-2 m deep and naturally exposed by coastal, lake or river erosion will be cleared of slumped soil by spade, and described and recorded. At each si...

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:
The field work in Trail Valley Creek and Inuvik aims to study: 1) how catchment characteristics, such as vegetation and soil properties, control the amount and quality of aquatic dissolved organic matter (DOM) and its microbial degradability, and 2) how these factors further regulate greenhouse gas fluxes (carbon dioxide CO2, methane CH4, nitrous oxide N2O) from Arctic lakes.
At the Dempster hi...

Summary:
The specific objectives of this project are:
1) to document trends in export of coastal, riverine and subterranean dissolved and particulate organic matter and carbon into the Arctic Ocean;
2) to determine their fate and related processes (origin and age, transport, physical, chemical, and biological transformation) in coastal waters and estuarine sediment; and
3) to assess the impacts of thes...

Objectives of the research are two-fold. First is to estimate structure, growth, and production of forest stands in northwestern Canada by applying a stand reconstruction and 3D ground-based laser techniques as well as stand measurement, aboveground litter collection, and find root sampling. Second is to examine the relationship between climate change in the high latitudinal regions and the patter...

201820172016201520142013 Summary:
This project is the continuation of year-round eddy covariance measurements of carbon, water and energy fluxes at Trail Valley Creek and Havikpak Creek, established in 2013.
The key methodology is tower-mounted micrometeorological measurements around the eddy covariance technique using an open-path infra-red gas analyzer and a sonic anemometer. These measurements are supported by measurements o...

2015 Summary:
The aim of this project is to study the short term and long term effects of different fire intensities on the decomposition of soil organic matter (SOM) in northern boreal forests under changing fire regimes.
The objectives are to: 1) explore the short and long term effects of forest fires with different intensity on above- and belowground biomasses; 2) explore changes in albedo, snow depths an...

Summary:
The objective of this project is to increase the understanding of taiga carbon balance of terrestrial and aquatic ecosystems and predict into the future the impacts of climate warming on these systems.
The exchange of carbon gases between the taiga and atmosphere is a significant component of the carbon balance and is dependent upon vegetation cover. The description below for the tundra site at...

2016 Summary:
The objectives of this research are to:
1) collect pieces of wood to measure tree rings and carbon and oxygen isotopes to determine past climate (mainly average summer temperature);
2) collect sand samples to date the layers which contain the wood and evidence of faulting, so the team can date they can be dated to show how old the wood and faults may be;
3) map the faults and tilting of the ...
