Summary: The research project goal is to collect surface sediments, bank and levee sediments, particulate sediments and shallow sediment cores from lakes in the Mackenie River Delta, and to evaluate their utility as potential archives of information concerning past permafrost stability by assessing down-core changes in the age and supply of terrestrial carbon. In 2007 and 2009, teams led by Prof. Tim Eglin...

Summary: 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. Th...

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. ...

Principal Investigator: Pearce, Tristan D
Licensed Year(s): 2011 2010
Summary: The researcher will work in collaboration with community members, local stakeholders, scientists and policy makers to complete the development of climate change adaptation plans in Paulatuk and Ulukhaktok and Aklavik. In Paulatuk and Ulukhaktok, ArcticNorth researchers working with local research assistants and coordinators, will reconvene the working groups from winter 2010 to review the preli...

Licensed Year(s): 2012 2011 2010
Summary: The goal of this research is to initiate time-series measurements of the CO2 system in the Mackenzie River, the major Arctic river in North America. This work will serve as the initial step towards long-term measurements and studies of the impacts of global warming on the CO2 systems in Mackenzie River, its estuary, and adjacent coastal waters. The field campaigns will include both diurnal and...

Licensed Year(s): 2011 2010 2009
Summary: The overall objective of this study is to develop a model that can be used to look at the vulnerability of small arctic lakes and ponds to changing climate. Lake Ice Study: Lakes 5A, 5B and Noell Lake (MAP-2 of the original licence application) will be visited in mid-April to measure lake ice. Holes will be made in the ice using an ice corer. Ice thickness and composition will be determined by...

Summary: The overall objective of this research is to improve our knowledge on present-day food webs/productivity in small Arctic pond/lake systems in order to better predict changes that could occur under changing climate. The methodology described below pertains to all research activities related to this research component dealing with fish. All other research activities related to this work were revi...

Licensed Year(s): 2010
Summary: The overall objective of the Lake 5A mesocosm study is to better understand the impact of permafrost thaw shoreline slumping (an analogue for a warming climate) on the bottom components of the aquatic food-web in small Arctic tundra lakes in order to better predict the effects of a warming climate on food-web structure, function and productivity. To assess the direct and indirect effects of per...

Principal Investigator: Solomon, Steven M
Licensed Year(s): 2010 2009 2008 2007
Summary: The western Arctic coast is among the most rapidly changing coastlines in the world and one of the most sensitive to climate change. The objective is to improve knowledge of physical conditions in the coastal zone in order to help government agencies, corporations, and local residents understand, mitigate and reduce the impacts of natural changes and industrial or community development. Spring...

Principal Investigator: Pollard, Wayne H
Licensed Year(s): 2010 2009
Summary: This licence is being issued for the scientific research application no. 946. The objective of this research is to better understand the distribution of underground ice in hydrocarbon development areas. By identifying how much ice there is, the researcher wants to study how oil/gas activities and climate change could affect the land. Underground ice is one of the most unpredictable and problema...
