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...


Lake expansion and wetland flooding on the Great Slave Lake Plain
Principal Investigator: Armstrong, Terry
Licensed Year(s): 2014 2013 2012 2011 2010
Summary: The primary objective is to examine changes in lake area in the ecoregion, investigate whether recent changes are part of a longer-term cycle related to large-scale weather patterns or due to permanent changes to the climate and hydrology of the region. Data collection in the field will consist of taking core samples from trees in the area. This technique involves using a hollow drill to cut i...


Evaluation of extreme events (ice jams) and deep scour holes on Mackenzie Delta channels
Principal Investigator: Prowse, Terry D
Licensed Year(s): 2008 2007 2006 2005 2004
Summary: This study is a continuation and expansion of two previous studies on extreme flooding and deep scour holes along the Mackenzie River. The researchers will use skidoos/toboggans towing a Ground Penetrating Radar (GPR) apparatus to try to find out what k...


Paleohydrological and Paleoecological Reconstruction of the Mackenzie Basin Deltas
Principal Investigator: Wolfe, Brent BBW
Licensed Year(s): 2007 2006 2005 2004 2003 2002
Summary: This ongoing research project will formulate a history of the frequency and magnitude of floods, droughts, and corresponding ecological responses in the Mackenzie Basin Deltas over the past 1000 years. Fieldwork in 2004 will focus on continued sampling a...


Extreme Flooding Events in the Mackenzie River Basin
Principal Investigator: de Rham, Laurent
Licensed Year(s): 2004
Summary: It is known that extreme flood levels within the Mackenzie River Basin are caused by ice jamming events. Analysis of open water versus ice influenced water levels at several sites within the Mackenzie River Basin will provide further quantification of th...


Biogeochemistry of Lakes in the Mackenzie Delta
Principal Investigator: Lesack, Lance
Licensed Year(s): 2017 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 research is to develop a biogeochemical model for lakes in the Mackenzie Delta, and ultimately, a model for flood plains and deltas of major world rivers that help understand the impact global change on rivers.. Specific goals...


I. Hydrologic and hydraulic aspects of northern hydrocarbon development; II. Sediment-related aspects of northern hydrocarbon development.
Principal Investigator: Jasper, Jesse
Licensed Year(s): 1993
Summary: The researchers will work in collaboration with other scientists to study water and sediment characteristics at certain Inland Water Directorate sites in the Mackenzie Delta. This study will be useful for evaluating impacts of hydrocarbon development as well as delta flooding on water flow, wildlife and vegetation in the delta. In addition, contaminants in water and sediments will be measured....


Hydrology of snow-filled arctic stream valleys
Principal Investigator: Heron, Richard
Licensed Year(s): 1993 1990
Summary: As part of an ongoing study in which field work was conducted in 1989 and 1990, this year's work will involve a study of the effects that snowdrifts can have on blocking the movement of meltwater in the McMaster River during the spring. Snowdrifts located at several sites along the river will be monitored to determine how they can alter the river's course, how these drifts are eventually broken d...


Distributed Snowmelt Modelling for Flood Forecasting in Northern Rivers
Principal Investigator: Soulis, E.D. (Ric)
Licensed Year(s): 1992
Summary: The purpose of the project is to improve the ways we have to predict the spring floods in the smaller rivers. Floods from snowmelt are a particular concern in northern rivers. In the Ft. Simpson area, spring flows from the smaller rivers, which are tributaries to the Liard and Mackenzie, have a great deal to do with the timing and nature of breakup on the major rivers. Snow conditions will be surv...


Mackenzie Delta Hydrology and Ecosystem Interactions
Principal Investigator: Marsh, Philip
Licensed Year(s): 1993 1992 1991
Summary: The research will study changes in the water levels of a variety of lakes in the Mackenzie Delta. Investigations will include consideration of factors controlling the lake levels, introduction of floodwater from the Mackenzie River, rainfall on to the lake, smowmelt runoff into the lakes and evaporation from the lakes....
