Implications of climate change and permafrost thaw on carbon dynamics and biodiversity in the lower MRB watersheds
Principal Investigator: Reid, Thomas
Licensed Year(s): 2024
Summary: This licence has been issued for the scientific research application No. 5507. The objectives of this research are to: 1) Assess the spatial and temporal distribution of particulate and dissolved nutrients/carbon along a large- and small-scale latitudinal gradients in the MRB (I.e. Slave River, Great Slave Lake, Mackenzie River, Laird River, Peel River, smaller headwater streams); Correlate...


Biogeochemistry of Lakes in the Mackenzie Delta
Principal Investigator: Lesack, Lance
Licensed Year(s): 2024 2023 2022
Summary: This licence has been issued for the scientific research application No.5320. The objectives of this project are to improve the understanding of methane cycling in Mackenzie Delta lakes and how it is affected by the changing water levels and to decipher the impact of water level changes on the ability of the Mackenzie Delta to affect riverine carbon and nutrient flow to the ocean. Improve un...


Quantifying carbon fluxes and budgets of boreal forest-tundra landscapes under the influence of rapidly changing permafrost regimes
Principal Investigator: Sonnentag, Oliver
Licensed Year(s): 2022 2021 2019 2018 2017 2016 2015 2014 2013
Summary: This licence has been issued for the scientific research application No.5220. The project of the present application is the continuation of year-round eddy covariance measurements of carbon, water and energy fluxes at Trail Valley Creek and Havikpak Creek, established in 2013. The key methodology is tower-mounted micrometeorological measurements around the eddy covariance technique using an ...


The annual scientific Arctic expedition onboard the Canadian research icebreaker CCGS Amundsen
Principal Investigator: Merzouk, Anissa
Licensed Year(s): 2021
Summary: This licence has been issued for the scientific research application No.4997. The aim of the research programs supported by the Amundsen in 2021 is to study on a long-term basis how climate induced changes are impacting the marine ecosystem, carbon cycle, contaminant transport, biogeochemical fluxes, and exchange processes across the ocean-sea ice-atmosphere interface in the Canadian Arctic Oce...


Large wood transport in the Mackenzie River Basin
Principal Investigator: Sendrowski, Alicia
Licensed Year(s): 2019
Summary: 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...


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 Objectives of this research are to: 1) Improve our understanding of microbial carbon-processing in Mackenzie Delta lakes and how it is affected by the changing water levels; and 2) Decipher the impact of water level changes on the ability of the Mackenzie Delta to affect riverine nutrient flow to the ocean. Specific activities for the coming field season include the following: (Goal 1) I...


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...


Recent changes in carbon source-sink relationships and greenhouse gas emissions in forest and peatland ecosystems along the Mackenzie Valley region of Canada
Principal Investigator: Bhatti, Jagtar
Licensed Year(s): 2011 2010 2009 2008 2007
Summary: The objectives of this research project are to: 1. map and assess changes in the distribution and composition of forest and peatland ecosystems due to climate changes; 2. estimate carbon storage (and variation) in boreal to arctic ecoregions of the Mackenzie valley; and 3. assess interannual and seasonal variations and key processes controlling carbon dioxide (CO2) and methane (CH4) dynamics. ...


Climate Geochemistry
Principal Investigator: Guo, Laodong
Licensed Year(s): 2005 2004
Summary: The purpose of this study is to collect river waters to determine the concentrations of dissolved organic carbon, particulate organic carbon, and nutrients, including nitrate, phosphate and silicate, and to examine their temporary variations related to c...
