Principal Investigator: Waite, Don
Licensed Year(s): 1993
Summary: In this study, we will collect air, dust and rain samples on a weekly basis at five Canadian locations during the months of June and July, 1993. Three locations are in the NWT while two locations are in Saskatchewan. The samples will be analyzed in Regina and Edmonton for the presence of certain insecticides, herbicides and PCB's that are known to be transported in the atmosphere....

Summary: Contaminants are carried in the air to the arctic during the winter when large-scale wind movements bring these contaminants from industrialized locations in North America, Europe and Asia to the north. Snow can collect these compounds from the air and bring them to the ground where they can accumulate. Thus, it is important to study the amount of contaminants in snow to determine the types and ...

Summary: Previous research has indicated that compounds containing bromine could play a role in the destruction of the ozone layer. This study is part of on-going research that is examining how important northern marine waters are as sources of bromine to the Arctic atmosphere. Seawater, snow and ice will be collected and assessed for bromine. In addition, measurements will be taken to determine if seaw...

Summary: "Brown ice" is caused by microscopic plants called ice algae. These plants comprise the base of the food chain, serving as food for small animals. Because of their dark colouration, ice algae absorb light and produce heat. We are studying what colours and how much light is absorbed by these plants. We are also measuring ozone concentrations over sea ice as well as the transfer of natural gases ...

Summary: The Norman Wells Observatory has demonstrated to be a very good site to place a remote aurora monitoring observatory to support a scientific experiment called SPIRIT II. For this project, the researchers will continue to investigate the aurora's strength and position, magnetic disturbances etc. The observatory at Norman Wells fills a gap in the internationally collected and shared auroral data se...

Principal Investigator: Brunskill, Gregg
Licensed Year(s): 1991 1990
Summary: The Researcher and team will obtain live fish for immediate field dissection and dry ice freezing of tissue samples for contaminant, enzyme and protein measurements. Large core samples of deep lake muds are sliced into thin layers in the field for radiochemical estimation of slice age and the measurements for organochlorines, PAHs, metals and other geochemical parameters....

Principal Investigator: Magor, Graeme
Licensed Year(s): 1990
Summary: The research team will carry out observational measurements of UV light reaching high latitudes of Ellesmere Island during the arctic spring....

Principal Investigator: Crook, E.D.
Licensed Year(s): 1990
Summary: The PEGSAT satellite will be put into near polar orbit, about 580 km altitute in early March. This small satellite contains two canisters of non-toxic chemicals which will be released during passes of the satellite over north-cental Canada. Scientist will tract the motion of the chemical in the Earth's magnetic and electrical fields with very sensitive optical equipment located at numerous ground ...

Principal Investigator: Lehn, W.H.
Licensed Year(s): 1987
Summary: To study the optical refraction and image transmission in the lower layer of the atmosphere, in particular under conditions of temperature inversion. To improve the understanding of these processes, and to continue to search for remote sensing techniques that provide temperature profiles through optical measurements....

Principal Investigator: Oguti, Takasi
Licensed Year(s): 1979
Summary: To conduct a study of the aurora borealis (northern lights) and its effect on the earth's magnetic field in the atmosphere and ground. Studies of HF waves may also be conducted....
