Flux of sediment-associated chemical elements in rivers draining to the Arctic Ocean
Principal Investigator: Bogen, Jim J
Licenced Year(s): 2010
Summary: The objective of this research is to estimate the modern and historical fluxes of sediment- associated chemical elements to the Arctic Ocean and their relationships to natural and man-induced changes in sediment yields and sediment sources and if possible, predict the impact of future climate changes on the fluxes. The study will include sampling of overbank sediments from floodplains and del...


IPY-SCARF: International Polar Year - Study of Canadian Arctic River-delta Fluxes
Principal Investigator: Lesack, Lance
Licenced Year(s): 2008 2007
Summary: 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, ...


Hydrological Studies, Mackenzie Delta Region
Principal Investigator: Marsh, Philip
Licenced Year(s): 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006
Summary: The objective of this project is to understand water and energy fluxes in northern regions, and to develop improved models of these processes. Project studies will look at both the atmospheric and surface water budgets of the Mackenzie Basin, with an emphasis on the effects of climate change on hydrology. The rates and processes controlling accumulation of snow, snowmelt, water flux through sno...


Evaluation of extreme events (ice jams) and deep scour holes on Mackenzie Delta Channels
Principal Investigator: Prowse, Terry D
Licenced Year(s): 2008 2007 2006 2005 2004
Summary: 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
Principal Investigator: Lesack, Lance
Licenced Year(s): 2016 2015 2014 2010 2009 2007 2006 2005 2004 2003 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993
Summary: 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...


ARDEX: Responses to Climate Change in Northern Aquatic Ecosystems
Principal Investigator: Vincent, Warwick F.
Licenced Year(s): 2004
Summary: The aim of this research is to define the influence of the Mackenzie Delta floods on the biological processes and patterns that persist in these shallow water ecosystems. The researchers are looking for links between the sediment on the bottom of the lak...


Sediment Sampling on the Slave River Delta, NWT
Principal Investigator: English, Michael C
Licenced Year(s): 2000 1996 1995
Summary: We will arrive at Fort Resolution on or about mid June and re-establish our base camp on Steamboat channel. For each day we are on the delta will be taking samples of sediment from the marshes of the outer delta area with a coring device. At the base camp we will take the core of sediment and section it into 2cm thick sections which will be air dried and shipped south for analysis....


Licence #5129
Principal Investigator: Syvitski, J.P.
Licenced Year(s): 1985
Summary: (1) To emplace current meter and trap arrays into 50m water depth via helicopter; (2) To site survey deltas to ascertain information On their hydrology and sedimentology processes and Quaternary history; (3) To site survey (re survey) coastal sections to understand their stability and geological history....
