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...

Biogeochemical variations in Pleistocene and Holocene-age permafrost across various ecological landscapes, western Canadian Arctic.
Principal Investigator: Lacelle, Denis
Licensed Year(s): 2014
Summary: The proposed project is a collaborative work between academic researchers, the NWT Geoscience Office and local communities. The objectives of the project are to: (1) investigate geochemical variations in the uppermost 3-5m of permafrost in the western Canadian Arctic; (2) assess potential geochemical implications of anticipated permafrost thaw on terrestrial and aquatic systems; (3) examine soil c...

Variability in peat plateau energy balance and water chemistry along a warming gradient
Principal Investigator: English, Michael C
Licensed Year(s): 2013
Summary: This research is physically based on a peat plateau and a peat bog, both close to Yellowknife. There are two primary objectives to this research. The first involves quantifying surface energy balances in areas where degradation of peat is pronounced and where it is not. Suprapermafrost water from the degraded and non-degraded sites will be analyzed for nutrients and dissolved organic carbon (DOC) ...

Degradation of dissolved organic carbon in Mackenzie Delta lakes and river channels
Principal Investigator: Tank, Suzanne E
Licensed Year(s): 2013 2012
Summary: This study will examine the solar degradation of riverine dissolved organic carbon (DOC) to carbon dioxide (CO2) throughout the Mackenzie River Delta. During the spring runoff peak just before summer solstice, ice-jam flooding inundates the Delta with river water, which spreads out in a relatively thin layer over an extended area and is exposed to 24-hour Arctic sunlight. This water is then slowly...

Composition of natural dissolved organic carbon in streams along latitudinal transect
Principal Investigator: Turetsky, Merritt R.
Licensed Year(s): 2011
Summary: The goal of this research project is to measure the concentration and composition of natural dissolved organic carbon in rivers along a latitudinal transect from central Alberta to southern NWT. Data on water quality will be combined with spatial data that describes the drainage basins of the sampled rivers, e.g. ecosystem composition, size, slope, recent fire impact and permafrost conditions. The...

Structure, Carbon Dynamics, and Silvichronology of Boreal Forests
Principal Investigator: Osawa, Akira

Summary: The main objective of the field work is to collect data in jack pine and black spruce forests on annual movement of organic matter and carbon. Additional objective is to conduct a regional study of stand development and its relationship to environmental factors in a several-square-kilometer study area of mostly black spruce. Five methods will be used. 1) Soil and air temperature will be measu...

Links between permafrost stability and terrestrial organic carbon export from the Mackenzie River
Principal Investigator: Eglinton, Timothy I
Licensed Year(s): 2011 2009 2007
Summary: Although the widespread permafrost soils in the Arctic rim have the ability to retain terrestrial organic carbon for many millennia, evidence indicates that the recent global warming trend may potentially lead to rapid permafrost destabilization and abrupt release of carbon stored in this vast reservoir. To assess whether this process is underway, and to evaluate its impact on biogeochemical proce...

Mapping and Modeling Carbon Flux in Northern Canada Related to Land Use Change
Principal Investigator: Chen, Wenjun
Licensed Year(s): 2005 2004
Summary: The research team is working to become familiar with the impact of human disturbances on vegetation in northern Canada for their carbon studies. The objective of this study is to collect vegetation and biophysical data for use as verification of ground cover type and disturbance for use in satellite imagery classification and biomass and soil sampling for carbon modeling along the Ingraham Trail....

The effect of UV light on bacterial growth rates in lakes and ponds in the Canadian High Arctic
Principal Investigator: Howard, Susan
Licensed Year(s): 1993 1992
Summary: Ozone depletion in the High Arctic could result in exposure of aquatic organisms (such as bacteria) to higher levels of ultraviolet (UV) radiation from the sun. This increased exposure to radiation may be harmful to bacteria and have an effect on organisms which feed on bacteria. I will collect water samples from lakes and ponds in the Resolute area in order to measure bacterial growth rates as ...
