2017 Baseline monitoring of marine productivity and oceanography spanning the Northwest Passage using ships of opportunity
Principal Investigator: Fisher, Jonathan AD
Licenced Year(s): 2017 2016
Summary: The first objective is to collect, analyze and report the findings from station-based and continuous plankton sampling and data on depth, temperature and salinity in the upper water column throughout Canada’s Northwest Passage. As a contribution to marine climate change research, this program will provide northern communities with the first regional-scale view of marine productivity—thereby provid...


Structure, Carbon Dynamics, and Silvichronology of Boreal Forests
Principal Investigator: Osawa, Akira
Licenced Year(s): 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006 2005 2004 2003 2002 2001
Summary: The 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 pa...


Effects of Climate Change and Landscape Perturbation on Arctic Tundra Lake Water Quality
Principal Investigator: Droppo, Ian G
Licenced Year(s): 2017
Summary: The overall goal of this study is to obtain information, through laboratory experiments (rainfall simulator; 2m annular flume) on sediments collected from retrogressive permafrost thaw shoreline slumps affecting numerous Arctic tundra lakes in the Mackenzie Upland Region east of the Mackenzie Delta, on the physical processes through which slump material is transported and delivered to a receiving ...


Long-term reconstructions of cold-season climate and atmospheric Hg deposition from ice wedges in the Mackenzie Delta region
Principal Investigator: Porter, Trevor
Licenced Year(s): 2017
Summary: This purpose of this research is to better understand long-term changes in winter temperatures and atmospheric mercury (Hg) in the Mackenzie Delta area over the last 11,700 years, a period known as the Holocene. The fieldwork aims to sample 20-30 ice wedges that represent a range of Holocene time. Precipitation stable hydrogen isotopes (a temperature proxy) and elemental Hg archived in the wedge i...


Pliocene landscape and paleoclimate change on Prince Patrick Island
Principal Investigator: Gosse, John C
Licenced 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 ...


Greenhouse Gas Exchange in the Outer Mackenzie Delta
Principal Investigator: Skeeter, Wesley R
Licenced Year(s): 2017
Summary: The objective of this campaign will be to measure the emission/uptake of methane and carbon dioxide at Fish Island in the outer Mackenzie Delta over a full growing season. This data will be used to determine the carbon balance of the island, and estimate the carbon balance of the land surfaces in the outer Mackenzie Delta. Additionally, the research team will investigate factors influencing the ex...


Long-term perspectives on aquatic ecosystem change with thawing permafrost
Principal Investigator: Korosi, Jennifer B
Licenced Year(s): 2017
Summary: The research team will re-survey 70 lakes originally sampled in 2005/06, to assess how conditions have changed in the intervening decade as thaw slumping has intensified and the Inuvik-Tuktoyaktuk Highway (ITH) was constructed. The team will assess how lake ecosystems responded to past climatic shifts throughout the post-glacial history of these lakes (10,000 years), and use these records to provi...


Permafrost and climate change, western Arctic Canada
Principal Investigator: Burn, Chris R
Licenced Year(s): 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006 2005 2004 2003 2002 2001 2000 1999 1998
Summary: The objective of this research is to understand the rate of ground warming in permafrost due to climate change and to measure the changes in ground surface characteristics that are occurring as a result. In particular, the research team are interested in changes in ground temperature, in the depth of the active layer, and in subsidence of the ground. The research team are also interested in measur...


Effects of fire on peatland permafrost stability and carbon cycling
Principal Investigator: Olefeldt, David
Licenced Year(s): 2017 2016 2015
Summary: The project team intend to study carbon cycling in peatland catchments, in order to determine whether the interactions between wildfire and permafrost thaw causes increased release of greenhouse gases from peatlands and aquatic ecosystems to the atmosphere, and thus cause amplified climate change. Given the overall objective of the project, the team intend to address five research questions: ...


Permafrost in the western Arctic
Principal Investigator: Kokelj, Steve V
Licenced Year(s): 2017 2016
Summary: The primary objectives of this research are: 1) to develop and test new methods of monitoring permafrost landscape change; 2) to investigate the impacts of natural and human disturbance on permafrost terrain and the ground temperature conditions in natural environments and in communities; and, 3) to assess the physical and chemical characteristics of permafrost. To achieve the objectives the r...
