IPY-SCARF: International Polar Year - Study of Canadian Arctic River-delta Fluxes
chercheur principal: Lesack, Lance
Année(s) de permis: 2008 2007
Résumé: The Arctic Ocean receives much higher river inflows than other ocean basins and this has major implications for sea-ice formation, for nutrient supply to the base of aquatic marine foodwebs, and for optical properties of ice-free areas and ice-pack margins via fluxes of dissolved organic matter and riverine particles. The Beaufort Shelf is strongly influenced by Mackenzie River outflows. However, ...

Evaluation of extreme events (ice jams) and deep scour holes on Mackenzie Delta Channels
chercheur principal: Prowse, Terry D
Année(s) de permis: 2008 2007 2006 2005 2004
Résumé: The objectives of this study are to quantify the frequency and magnitude of ice jams in the Mackenzie River Delta, including the hydroclimatic conditions controlling their occurrence and associated floods, develop a hydraulic model of it, and investigate the importance of deep scour holes in the Mackenzie River. This study is an expansion of previous research conducted in 2004. Ice jamming has ...

Biogeochemistry of Lakes in the Mackenzie Delta
chercheur principal: Lesack, Lance
Année(s) de permis: 2017 2016 2015 2014 2010 2009 2007 2006 2005 2004 2003 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993
Résumé: The long-term goal of this project is to develop a biogeochemical model for lakes in the Mackenzie Delta, and ultimately, a more general ecosystem model for floodplains and deltas of major world rivers that will help assess the effects of multiple stresses on rivers resulting from global change. Numerous major river deltas in the Arctic circumpolar region are lake-rich because of thermokarst effec...
