Subarctic Lakes in a Changing Climate (SLACC) - Lake studies in the Yellowknife area
Principal Investigator: Palmer, Mike
Licensed Year(s): 2024 2023
Summary: This licence has been issued for the scientific research application No.5531. The overarching objective of this program is to take an ecosystem approach to assessing how multiple environmental stressors impact aquatic habitats in subarctic shield terrain. There are three central activities that will be undertaken with this license and they are designed to address the specific objectives below: ...


Carbonate precipitation in the Mesproterozoic Society Cliffs Formation, Bylot Supergroup, on northern Baffin Island
Principal Investigator: Kah, Linda
Licensed Year(s): 1994 1993
Summary: Characteristics of ancient sediments reveal information about the chemical, biological and physical environment within which these sediments were formed. By studying the patterns of rocks found in the north Baffin area, I hope to discover how much of the formation of these rocks was due to the algae that lived in ancient oceans, and how much was due to the chemical makeup of the water. The resea...


From ice algae to sediments in the frozen arctic seas: the contribution of direct sedimentation and zooplankton grazing on the vertical flux of carbon
Principal Investigator: Fortier, Louis
Licensed Year(s): 1994
Summary: The researchers will be examining small marine organisms (algae, zooplankton and phytoplankton) to determine their influence on global warming. Carbon is necessary for the production of carbon dioxide (CO2), and increase levels of CO2 in the atmosphere can contribute to an increase in the earth's overall temperature. The study will examine how these small marine creatures can reduce carbon level...


Palynology and Stratigraphy of the Lower Cretaceous MT. Goodenough Formation, Aklavik Range, NWT
Principal Investigator: McIntyre, David J.
Licensed Year(s): 1992 1990
Summary: The Researchers will collect rock samples for study of fossil algae (dinoflagellates) and will determine the geological age. They will correlate findings with similar material from wells and will determine climate and environment conditions at the time the rocks were deposited....


Biogenic Bromine Production in Arctic Waters and Ice Algal Physiology and Sea Ice Optics
Principal Investigator: Cota, Glenn
Licensed Year(s): 1994 1993 1992 1991
Summary: Some natural gases in air react with light and can cause ozone depletion near the earth's surface. Some of these gases are produced by marine plants or algae such as seaweeds and the small single-celled plants causing "brown ice". The researchers will find out what marine plants which contain and/or release these materials called "organohalogen gases". This study will help to determine how much ...


Limnology and Paleoecology of Arctic Lakes: Belcher Islands and Yellowknife Area
Principal Investigator: Smol, John P
Licensed Year(s): 1991 1990
Summary: The Researchers will collect water samples from lakes and ponds to assess the present water quality. Lake and pond mud samples will also be taken to identify algal indications of lake quality....


Sea Ice Optics
Principal Investigator: Maykut, Gary
Licensed Year(s): 1991
Summary: The Researcher and team will carry out measurements on the shorefast ice next to the PCSP base at Resolute. They will monitor the amount of incoming light at the surface and within the ice. The sunlight transmitted through the ice cover fuels much of the biological activity that takes place in the polar regions. The data will be used to test a theoretical model for predicting light transmission t...


A Paleolimnological Approach to Environmental Reconstruction on the Pre-Foxe Terrain of Cumberland Peninsula, Baffin Island
Principal Investigator: Wolfe, Alexander P.
Licensed Year(s): 1992 1991 1990
Summary: During the last glacial period, 110,000 to 5,000 years to present some lakes escaped glaciation. The Researcher will retrieve sediment cores from three upland lakes to investigate the physical responses of the sediments and the biological responses of algae toward this climatic event....


Northern Ellesmere Wintering Over Project 1990/91
Principal Investigator: Bird, D. le R.
Licensed Year(s): 1990
Summary: The researcher will carry out monthly collections of snow for analysis; ice algae from ice cores; ice crystals for analysis; snow samples during snow storms and a three-hourly traditional meteorology program....
