Long-term perspectives on aquatic ecosystem change with thawing permafrost
Principal Investigator: Korosi, Jennifer B
Licenced Year(s): 2017
Summary: The research team will re-survey 70 lakes originally sampled in 2005/06, to assess how conditions have changed in the intervening decade as thaw slumping has intensified and the Inuvik-Tuktoyaktuk Highway (ITH) was constructed. The team will assess how lake ecosystems responded to past climatic shifts throughout the post-glacial history of these lakes (10,000 years), and use these records to provi...


Assessment of the condition of freshwater streams in the South Nahanni watershed
Principal Investigator: Steedman, Audrey
Licenced Year(s): 2016
Summary: The main objectives of this research project are to determine if macroinvertebrate community structure and composition is changing over time in freshwater streams in the South Nahanni watershed; and, to determine whether mining activities degrade the health of streams in the South Nahanni Watershed and define zones of degradation due to mining activities. These test sites are downstream of mines. ...


Collection of Silurian fishes and trilobites and articulated remains of Devonian chondrichthyans and other fishes from the Mackenzie Mountains, N.W.T.
Principal Investigator: Wilson, Mark V.H.
Licenced Year(s): 2013 1998 1996 1990
Summary: The objectives of the research are 1) to collect remains of Silurian and Devonian fishes, and 2) to collect remains of Silurian trilobites. Activities are limited to travel, residence at camp locations and collection of fossils. Helicopters will be used to access camp sites. We plan to land at Avalanche Lake on July 15, spending 6 days collecting fossils at Avalanche Lake, followed by one day of t...


Trilobite biostratigraphy of Rockslide Formation (Middle Cambrian)
Principal Investigator: Pratt, Brian R.
Licenced Year(s): 2012 2002 2000 1998
Summary: Outcrops in the Mackenzie Mountains preserve an almost uninterrupted sequence of strata of Cambrian age. This study aims to collect in bed-by-bed detail the trilobite fossils from the Rockslide Formation, the Middle Cambrian portion of the sequence. The taxonomy and biostratigraphy of these fossils will generate a refined time scale for this part of the geologic column, some half a billion years o...


Continuation of the research and fieldwork on Ellesmere and Banks Island of a biostratigraphic program on the marine fauna from the Eureka Sound Formation.
Principal Investigator: Zinsmeister, William J.
Licenced Year(s): 1988 1987
Summary: To determine: (1) the composition of the marine invertebrate faunas of the Eureka Sound Formation; (2) the stratigraphic distribution of individual taxa so that a biostratigraphic zonation could be established; (3) the biogeographic relationships of the faunas of the Eureka Sound Formation with temporal faunas of the North Atlantic....


Licence #5047
Principal Investigator: Aitken, Alec
Licenced Year(s): 1985
Summary: Collecting fossil clams from raised marine deposits in the vicinity of the villages to aid our understanding of marine ecology at the end of the Wisconsin Ice Age....
