The objectives of this survey are to establish patterns of methane (CH4) concentration in the atmosphere over the Mackenzie delta region and to quantify the emission of CH4 from these areas. Together with the data from previous data the research team should be able to estimate the annual contribution of the Mackenzie delta region to the atmospheric methane budget. Furthermore the research team wil...

The central aim of the ArcticNet marine-based research program is to study on a long-term basis how climate induced changes are impacting the marine ecosystem, contaminant transport, biogeochemical fluxes, and exchange processes across the ocean-sea ice-atmosphere interface in the Canadian Arctic Ocean. The knowledge generated from this multi- year program is integrated into regional impact studie...
Principal Investigator:Sonnentag, Oliver Licenced Year(s):
This project will address the following questions:
1) What is the net effect of permafrost thawing-induced biophysical and biogeochemical feedbacks to the climate system?
2) How do these two types of feedback differ between the discontinuous and continuous permafrost zones?
3) Is the reported decrease (increase) in net CO2 (CH4) exchange based on plot- (<1m2) and ecosystem-scale (~1km2) flux m...

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...

These research activities combine investigations of clouds and atmospheric aerosol in the Beaufort Sea. The main aim of the cloud studies is to improve the understanding of the cloud-related processes in the Arctic atmosphere and to use these measurements to improve the performance of regional and global climate models of the Arctic. To understand cloud processes knowledge on aerosol properties wh...
Principal Investigator:Bottenheim, Jan W Licenced Year(s):
The goal of this project is to take part in establishment of a long-term observation network to measure concentrations of two important greenhouse gases (ozone and carbon dioxide) as well as bromine oxide. Bromine oxide is a key chemical reagent determining the presence of ozone accompanied with full set of meteorological data and detailed geographic information across the Arctic Ocean and Hudson ...

The central aim of the ArcticNet marine-based research program is to study on a long-term basis how climate induced changes are impacting the marine ecosystem, contaminant transport, biogeochemical fluxes, and exchange processes across the ocean-sea ice-atmosphere interface in the Canadian Arctic Ocean. Ultimately, the knowledge generated from this multi-year program will be integrated into region...

Climate change and sea ice change affects all who live in the north. The aim of this project is to improve understanding of the physical processes in Arctic clouds and their contribution to the current changes in the polar environment, and thereby reducing uncertainties in regional and global model simulations important for future weather and climate prediction.
These research activities combin...

The research team intends to study how important greenhouse gases, carbon dioxide and methane, are exchanged between tundra surfaces and the atmosphere. They will measure these exchanges over various tundra types and relate them to environmental variables such as soil properties and weather, in hopes of understanding more about how future climate change will impact the land surface and how these ...

The main aim of these weather and air quality studies is to improve the understanding of the processes in the Arctic atmosphere and to use these measurements to improve the performance of regional and global climate models of the Arctic. The aim of the sea ice studies is to obtain a snapshot of ice thickness in a vast region of the Arctic, and to create an inventory of Arctic sea ice volume.
