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...

The objective of this research project is to study ice processes on the Hay River in order to continue the ongoing development of computer models to predict them.
In order to develop realistic models, it is important that the researchers have the opportunity to observe river breakup so as to have a full understanding of the physical context of the historical data. In addition, long term data re...
Principal Investigator:Armstrong, Terry Licenced Year(s):2014
The objectives of this project are to draw together multiple sources of information so that the research team may (1) examine change in lake area in this ecoregion, (2) assess amount of meadow habitat lost to rising water levels in core bison range, (3) investigate whether recent changes are part of a longer-term cycle and evaluate the causes of this change, (4) determine a way to document and int...
Principal Investigator:Wesche, Sonia D Licenced Year(s):
The over-arching objectives of the project are to draw together multiple sources of information to (1) examine the change in lake area in this eco region, (2) quantify the type and amount of habitat loss or modification; (3) investigate whether recent changes are part of a longer-term cycle and evaluate the causes of this change; (4) document local and traditional knowledge of physical and biologi...
Principal Investigator:Prowse, Terry D Licenced Year(s):
The objective of this study is to quantify the frequency and magnitude of ice jams in the Mackenzie River Delta; the hydroclimatic conditions controlling the occurrence of ice jams and associated floods; to develop a hydraulic model of ice jamming for the Mackenzie Delta, and to investigate the importance of deep scour holes in the Mackenzie River.
Quarterly field trips are scheduled for mid-Ma...

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...
Principal Investigator:Forbes, Donald L Licenced Year(s):
Safe and sustainable hydrocarbon development and potential impacts of climate change on coastal infrastructure and subsistence activities require improved knowledge and understanding of coastal and nearshore seabed properties, and coastal hazards such as...
Principal Investigator:de Rham, Laurent Licenced Year(s):
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...
Principal Investigator:Lamoureux, Scott F Licenced Year(s):
The objective of the research is to supplement and extend instrumental climatological and hydrological records in the NWT using dendrochronology (tree-ring) and varved lake sediment analysis. Transportation to the site will be by charter aircraft from Fo...
