Principal Investigator: Fix, Andreas
Licensed Year(s): 2022
Summary: This licence has been issued for the scientific research application No.5211. This project will use aircraft-based instruments using both remote-sensing and in-situ-techniques to carry out measurements of methane and carbon trace gases and tracers related to their emissions. The results will help to better understand the global methane and carbon cycle. This mission makes use of the German r...

Principal Investigator: Boike, Julia
Licensed Year(s): 2021 2020 2019 2018
Summary: This licence has been issued for the scientific research application No.5023. The goals for this expedition are to test new equipment for characterizing the energy fluxes from and around thermokarst slumps and to establish a baseline for future subsidence measurements. Additionally, lake and atmospheric methane concentrations in relation to thermokarst slumps will be quantified. The research...

Principal Investigator: Olefeldt, David
Licensed Year(s): 2021 2019 2018
Summary: This licence has been issued for the scientific research application No.4734. The objective of this research is to identify impacts of climate change and permafrost thaw on pond methane emissions, and on water chemistry in streams that drain peatland-rich catchments. Impacts on methane emissions will be assessed. Specific objectives are: 1) to characterize the trends and variability in magn...

Principal Investigator: Risk, Dave
Licensed Year(s): 2019
Summary: The research team will use the newly develop ExACT (Emissions Attribution via Computational Techniques) system, a completely novel and innovative approach to survey gas emissions from natural and manmade sources. ExACT consists of computer algorithms applied to geo-located multi-gas data collected during vehicle-based surveys. Data collection involves a combination of multi-gas analyzers, targetin...

Principal Investigator: Orcutt, Beth N
Licensed Year(s): 2017 2016 2015
Summary: The focus of this one-year-long project is to study methane release from six different lakes in the Mackenzie Delta and Richards Island area, with a focus on capturing a full ice in/ice out cycle, to determine how much methane is released from lakes under different conditions and how microorganisms increase or decrease methane release. The research team will to undertake two distinct activitie...

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...

Principal Investigator: Sachs, Torsten
Licensed Year(s): 2016 2013 2012
Summary: The objectives of this study are to quantify the surface-atmosphere methane emissions over large areas, and to analyze the influence of different surface and vegetation characteristics on large area methane emissions (process understanding). The research team proposes to measure methane fluxes between the tundra and the atmosphere by airborne eddy covariance, a micro-meteorological method. Flux...

Principal Investigator: CLARK, Ian D.
Licensed Year(s): 2000 1999
Summary: Data will be collected that can help to predict climate of the near future and determine the impact of temperature change on northern hydrology. The investigator will attempt to better understand how methane-producing bacteria function giving us a better understanding of their feedback on climate change. The research area is a quarry along the Dempster highway east of Campbell Lake. This site w...
