Quantifying carbon fluxes and budgets of boreal forest-tundra landscapes under the influence of rapidly changing permafrost regimes
chercheur principal: Sonnentag, Oliver
Année(s) de permis: 2022 2021 2019 2018 2017 2016 2015 2014 2013
Résumé: Through this project the research team will address the following objectives: What is the net effect of permafrost thawing-induced biophysical and biogeochemical feedbacks to the climate system? How do these two types of feedback differ between the discontinuous and continuous permafrost zones? Is the reported decrease (increase) in net CO2 (CH4) exchange based on plot- (<1m2) and ecosystem-scale ...


Structure, Carbon Dynamics, and Silvichronology of Boreal Forests
chercheur principal: Osawa, Akira
Année(s) de permis: 2019 2018 2016 2015 2013 2012 2011 2010 2009 2008 2007 2006
Résumé: Main objective of the field work is to collect data in jack pine and black spruce forests on annual movement of organic matter and carbon. Additional objective is to conduct a regional study of stand development and its relationship to environmental factors in a several-square-kilometer study area of mostly black spruce. Five methods will be used. 1) Soil and air temperature will be measured...


Carbon Dynamics in Chronosequence of Boreal Forest Ecosystems: a Production Ecological Approach
chercheur principal: Osawa, Akira
Année(s) de permis: 2017 2005 2004 2003 2002 2001
Résumé: Northern forests are closely connected to the issue of global warming because they are likely to absorb much of the carbon dioxide that is emitted into the air by humans. The amount that these forests absorb, however, is not clear. The research team will...
