Nitrogen sources for Arctic freshwaters (NitroFresh)
chercheur principal: Pastor, Ada
Année(s) de permis: 2021
Résumé: This licence has been issued for the scientific research application No.5034. The main aim of Nitrofresh is to assess the nitrogen (N) sources for streams and the linkages between terrestrial and freshwater ecosystems across different regions with continuous permafrost in High Arctic. In particular, the research team have three objectives: 1) to quantify and characterize N pools along the ripar...

Controls on carbon and nutrient cycling in arctic tundra
chercheur principal: Grogan, Paul
Année(s) de permis: 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008
Résumé: The goal of this research over the next five years is to substantially advance the understanding of how Canadian arctic tundra ecosystems function, and therefore how they are likely to be affected by perturbations such as climate change, resource development and extraction, and atmospheric pollution. Specifically, the research team will focus on the impacts on vegetation due to warmer summer tempe...

Climate Change Impacts on Canadian Arctic Tundra Ecosystems: Interdisciplinary and Multi-scale Assessments
chercheur principal: Coxson, Darwyn S
Année(s) de permis: 2008 2007
Résumé: The objective of this research is to study how northern soils in close proximity (geospatially linked soils) cycle nitrogen and carbon and produce greenhouse gases. Describing these links will allow forecasting on how the soils respond to climate change. Three transects with 31 sampling locations will be set up. At each location a Time Domain Reflectometry (TDR) probe and thermocouple will be i...

Constraints To Ecosystem Development in High Arctic Polar Deserts
chercheur principal: Bliss, Lawrence
Année(s) de permis: 1994
Résumé: We seek to better understand how ecosystems develop in the high arctic following retreat of ice caps. This includes studies of soil development and the influence that rocks play in this as well as studying the development of block crusts of organisms that form on the soil surface. We will also try to understand the role these crusts play in fixing nitrogen and influencing the development of flower...
