Progressive behavioural innovation in Ediacaran and Cambrian burrowing animals from the Mackenzie Mountains (NWT, Canada)
Principal Investigator: Narbonne, Guy
Licenced Year(s): 2013 2012
Summary: The world’s earliest animals appeared in the Ediacaran Period about 580 million years ago, and soft worm-like animals capable of movement appeared suddenly worldwide 555 million years ago. The previous studies (Narbonne and Aitken, Palaeontology, 1990; MacNaughton and Narbonne, Palaios, 1999; Narbonne, The Rise of Animals, 2007) have shown that these fossils are especially well represented in the ...


Anticancer Agents from Microorganisms
Principal Investigator: Pettit, George
Licenced Year(s): 1999 1995
Summary: The overall goal of this project is to collect a variety of soil samples from easily accessed locations in the NWT. Small soil and mud samples will be taken along NWT highways 1,3, and 7 during the late summer. All travel will be on highways, with actual collections made on foot. Soil samples will consist of only a few grams of material at each location. The samples will be taken to the University...


Proterozoic reefs in the Mackenzie Mountains
Principal Investigator: Narbonne, Guy
Licenced Year(s): 2001 1999 1998 1996 1994 1992 1991 1989 1988
Summary: For several years researchers have been examining a rock unit called the Sheepbed Formation in the Mackenzie Mountains. In 1998 fossil reefs were located in this structure. The goal of the 1999 field season is to identify the types of organisms which created the reef structures and what the climate was like when they were built. Members of the field party will be transported to the base camps by h...


Constraints To Ecosystem Development in High Arctic Polar Deserts
Principal Investigator: Bliss, Lawrence
Licenced Year(s): 1994
Summary: We seek to better understand how ecosystems develop in the high arctic following retreat of ice caps. This includes studies of soil development and the influence that rocks play in this as well as studying the development of block crusts of organisms that form on the soil surface. We will also try to understand the role these crusts play in fixing nitrogen and influencing the development of flower...


Study of bio-indicators of environmental change in arctic lakes
Principal Investigator: Smol, John
Licenced Year(s): 1994 1993 1992
Summary: The researchers plan to take samples of lake water and lake sediments from a variety of sites in the region. From these samples, information will be collected about the water chemistry, microscopic organisms present in the lakes, and changes in the region's past environmental and climatic conditions....


Study of potential environmental impacts of waste materials in the marine waters near Cambridge Bay
Principal Investigator: Johnston, Laura
Licenced Year(s): 1993
Summary: Samples of sediment, water and different marine species such as fish, marine invertebrates (including sea urchins, clams and crabs), and microscopic organisms will be collected by divers from the underwater dumpsite in Cambridge Bay. These samples will be assessed for contaminants such as heavy metals and PCB's. The study is primarily being conducted to determine if the waste materials of the du...


Ecology of high arctic marine molluscs
Principal Investigator: Aitken, Alec
Licenced Year(s): 1993 1992
Summary: The researcher will collect samples of small organisms that live on the sea bottom in the Canon and Slidre Fiords of Ellesmere Island. These creatures include small worms, shrimp, starfish, clams and snails. Measurements will be collected on water temperature and the amounts of salt and oxygen in the water. These data will help to relate the distribution of species with the characteristics of ...


Biogeochemistry of lakes in the Mackenzie Delta
Principal Investigator: Lesack, Lance
Licenced Year(s): 2016 2015 2014 2010 2009 2007 2006 2005 2004 2003 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993
Summary: This research involves a variety of activities that involve investigating the chemical makeup of ice, streams and lakes. In addition, some work will be conducted on measuring the microscopic and larger organisms (e.g., algae and bugs) present in streams. Most of the field work will be based out of the Inuvik Research Centre with some work conducted in collaboration with Dr. P. Marsh at Trail Val...


Spatial Variation and Scale in Terrestrial and Marine Inorganic and Organic Substance Distributions
Principal Investigator: Reimer, K.J.
Licenced Year(s): 1992 1991
Summary: The research team will collect bottom-dwelling marine organisms and sediment to examine how materials introduced locally and from distant sources distribute themselves in the marine environment, to understand the potential for adverse effects and the likely persistence of such materials in the future. As well, they will collect soil and plant samples to understand the potential for impact and per...


Comparison of Tissue and Plasma Fatty Acid Composition from Temperate and Arctic Marine Organisms
Principal Investigator: Glemet, Helene
Licenced Year(s): 1991 1990
Summary: The Researcher will collect blood/hemolymph and tissues from representative Arctic marine fish, echinoderm, crustacean and mollusc species. The fish will be netted and the invertebrates dredged. Samples will be analyzed for their fatty acid composition. A sample size of 6-8 individuals will be required from each species....
