Structure, Carbon Dynamics, and Silvichronology of Boreal Forests
Principal Investigator: Osawa, Akira
Licensed Year(s): 2019 2018 2016 2015 2013 2012 2011 2010 2009 2008 2007 2006
Summary: 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...


Short and long term effects of forest fires on the stability of carbon pools in the arctic permafrost and subarctic forests (ARCTICFIRE)
Principal Investigator: Koster, Kajar
Licensed Year(s): 2018 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...


Boreal Forest Carbon Balance Studies
Principal Investigator: Layden, Ronald E.
Licensed Year(s): 2017
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...

Pliocene landscape and paleoclimate change on Prince Patrick Island
Principal Investigator: Gosse, John C
Licensed Year(s): 2017 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 ...


Biogeochemistry of Lakes in the Mackenzie Delta
Principal Investigator: Lesack, Lance
Licensed Year(s): 2017 2016 2015 2014 2010 2009 2007 2006 2005 2004 2003 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993
Summary: The objective of this research project are to: 1) improve the understanding of microbial carbon-processing in Mackenzie Delta lakes and how it is affected by the changing water levels; and, 2) to decipher the impact of water level changes on the ability of the Mackenzie Delta to affect riverine nutrient flow to the ocean. This work will help resolve what drives microbial communities in Mackenzi...


Airborne Observations in Support of NETCARE
Principal Investigator: Abbatt, Jon
Licensed Year(s): 2015
Summary: The NETCARE observations will be covered the range from Longyearbyen, Svalbard (European Arctic) until Inuvik (NWT – Polar 6 aircraft only) and Barrow (Alaska – Polar 5 aircraft only). The observational platforms will be two aircraft: 1) the Alfred Wegener Institute (AWI) POLAR 5, a modified DC-3 aircraft; and 2) the AWI POLAR 6, also a modified DC-3 aircraft. The two platforms will be coordin...


Soil Carbon in the Mackenzie Delta Region
Principal Investigator: Phillips, Marcus R
Licensed Year(s): 2015 2014 2013
Summary: The goal of this research is to understand how landscape processes influence the quantity and quality of soil carbon in the Mackenzie Delta Region. Particular attention will be paid to the depth distribution of soil carbon and how it is affected by differences in vegetation and soil forming processes. Key environmental differences that will be examined include forest vs. tundra and delta vs. uplan...


Climate change and structure of circumpolar boreal forests during the past century
Principal Investigator: Osawa, Akira
Licensed Year(s): 2014
Summary: Objectives of the research are two-fold. First is to estimate structure and growth of forest stands in northwestern Canada by applying a stand reconstruction technique. Second is to examine the relationship between climate change in the Arctic region and the patterns of forest biomass growth during the past century. The research team also measure currently occurring growth and carbon dynamics of f...


Arctic Peatland Carbon and Holocene Warm Climates
Principal Investigator: Beilman, David W
Licensed Year(s): 2013
Summary: The research team seek to understand carbon dynamics during warm climate intervals in the Arctic: the Holocene Thermal Maximum (HTM) the warmest pre-industrial interval ranging in timing from 10 ka (thousands of years before present) with maximum seasonality to 6 ka with reduced seasonality, and the Medieval Climate Anomaly (MCA) at ~1 ka with similar seasonality as today. By studying peat cores f...
