Using Novel Technology to Survey Methane Emissions in the Mackenzie Delta
chercheur principal:
Année(s) de permis: 2019
Résumé: The research team will use the newly develop ExACT (Emissions Attribution via Computational Techniques) system, a completely novel and innovative approach to survey gas emissions from natural and manmade sources. ExACT consists of computer algorithms applied to geo-located multi-gas data collected during vehicle-based surveys. Data collection involves a combination of multi-gas analyzers, targetin...

NSERC Canadian Lake Pulse Network: more than 660 Canadian lakes sampled over three summers.
chercheur principal:
Année(s) de permis: 2019
Résumé: 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...

Where on Earth is fire-derived carbon stored?
chercheur principal:
Année(s) de permis: 2019
Résumé: 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...

Large wood transport in the Mackenzie River Basin
chercheur principal:
Année(s) de permis: 2019
Résumé: 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...

Ice Bird 2019
chercheur principal:
Année(s) de permis: 2019
Résumé: 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 ...

Airborne laser mapping
chercheur principal:
Année(s) de permis: 2019 2018
Résumé: Collect airborne laser scanning data over biomass plots over NWT. Specifically to develop biomass and forest resource models for GNWT multi source inventory, and to assess how the resource is changing through time and in space due to climate and fire influences. Airborne laser data coverage is calibrated by field plot data (most provided by GNWT) and models are created which are then upscaled t...
