Résumé: The objective of this research is to revisit fixed sample stations at near-field, mid-field and far-field sites over the course of the year in an effort to determine any seasonal variation that may exist and confirm impact predictions. The AEMP Version 3.5 will consist of the following components; Dust Deposition; Effluent and Water Chemistry; Indicators of Eutrophication; Sediment Chemistry; P...


Marian Watershed Community-Based Aquatic Effects Monitoring Program
chercheur principal: Garner, Kerri
Année(s) de permis: 2013
Résumé: The Tlicho Lands Moratorium was lifted in June 2013, and development pressure is expected to increase on Tlicho Lands. As Tlicho Lands are in relatively pristine condition, the intent of this study is to begin to collect baseline data at sites prioritized by community members away from specific project footprints in order to analyze the cumulative impacts of development, climate change, and increa...


2012 Baseline Aquatic Program for Avalon Rare Metals Inc. Proposed Thor Lake Rare Earth Element Project
chercheur principal: Sibbald, Carey
Année(s) de permis: 2012 2011 2010 2009 2008
Résumé: The objective of the 2012 Aquatics program is to continue baseline data collection to further characterize the baseline water and sediment quality and aquatic communities at specific lakes within the Thor Lake area and Avalon's Thor Lake Rare Earth Elements Project footprint. Water, sediment and aquatic organisms will be collected at up to 11 stations (10 lakes) within the Thor Lake area. Most ...


Aquatic Environmental Effects Monitoring - Flat River at Cantung Mine
chercheur principal: Hoos, Rick
Année(s) de permis: 2012 2009 2002
Résumé: The objectives of this research are: (1) to determine length, weight, and general condition of 100 fish and tissue analysis of not more than 10 fish (Slimy Sculpin- Cottus cognatus) per site at five site locations in the Flat River: two locations upstream of the CanTung mine site, one adjacent to the mine site and at two locations downstream of the mine site; and, (2) to determine sediment and wa...


Con Mine Environmental Effects Monitoring (EEM) Cycle 2
chercheur principal: Machtans, Hilary
Année(s) de permis: 2018 2015 2012 2009 2007
Résumé: The main objective of the present study is to characterize site conditions to fulfill specific requirements of federal regulations. These studies will include fish, fish habitat, benthic macroinvertebrates, sediment and water quality sampling. Study areas will include locations both exposed and unexposed to mine effluent. The purpose of these surveys is to characterize environmental conditions ...


Characterization of the reference condition of northern biota and assessment of potential changes due to mining
chercheur principal: Dube, Monique G
Année(s) de permis: 2006
Résumé: The objectives of this research are three-fold: 1) to determine the natural variability of benthic invertebrate and fish communities at sites free of human impact; 2) to determine any changes in these due to mining activity relevant to regional variability; and 3) to establish dose response relationships and critical thresholds for stressors including mine effluent, ammonia, a hydrocarbon indicato...


Assessment of Impacts of Mackenzie Delta Petroleum Activities on Aquatic Ecosystem Health, Year 1: Lakes (Parsons Lake Anchor Site)
chercheur principal: Halliwell, Douglas
Année(s) de permis: 2004
Résumé: The objectives of this program are; 1) to characterize baseline water, sediment, and benthic invertebrate conditions in one experimental lake (Parsons Lake) and two control lakes near the Mackenzie Gas Project's (MGP) Parsons Lake Anchor Site; 2) to cho...

The Use of Sediment Data as an Indicator of Aquatic Ecosystem Health in the Coppermine River Basin, NWT
chercheur principal: Peramaki, Liisa
Année(s) de permis: 2000
Résumé: This study will investigate the quality of aquatic sediment and evaluate its potential as an indicator of ecosystem health in the Coppermine River basin. Sediment cores will be collected by boat or float plane at Lac de Gras and Point Lake. The following field measurements will be recorded: water temperature and pH, and sediment colour, texture and pH. In addition, personal interviews will be c...
