Summary: The monitoring objectives of this project are: to conduct a targeted scientific program to analyze heavy metals and trace elements and stable isotopes in vegetation (caribou food); to correlate the results in vegetation with concentrations in caribou from a related NCP program [Gamberg 2006]; to test if contaminant patterns in caribou tissues will vary with patterns observed in lichen/moss, or wil...

Summary: The objectives of this study are to: 1) inventory the size and morphometry of glaciers in the Ragged Range; 2) find and document geological and botanical evidence of former glacier activity; 3) develop a chronology for Holocene glacier activity in the Ragged Range; and, 4) develop one or more growth curves for lichens growing on carbonate and/or silicate rocks. Also, the field reconnaissance and b...

Summary: This fieldwork is for reclamation planning at the Tundra Mine site. An aquatic survey will be conducted to characterize the current conditions of water bodies adjacent to the Tundra Mine and downstream of the mine's two tailings ponds. A total of seven l...

Summary: I will be collecting lichens in the vicinity of Iqaluit in order to better understand the variety of species that grow in the high arctic. Some species of fungi grow with algae: these partnerships are recognized as lichens. In an attempt to study this partnership, I will separate the fungi part from the algae and grow each separately in a laboratory. I will also be visiting Greenland and Icelan...

Summary: Project 1: Small samples of lichens will be collected from approximately 20 sites located along the Hood River and analyzed for contaminants. Lichens are good indicators of the types of air-borne contaminants that have been carried north to the arctic since they absorb their nutrients from the air. Project 2: The researcher will examine plant communities along the Hood River in order to study th...

Principal Investigator: Shilts, William W.
Licensed Year(s): 1993 1992 1991
Summary: The focus of this project is on examining the glacial and periglacial features of southern Bylot Island and the area near Pond Inlet. Researchers and graduate students will be collecting data on lichens, ice, land features and organisms in order to gain a better understanding of why glaciers of the area are retreating (melting)....

Principal Investigator: Aspler, L.B.
Licensed Year(s): 1993 1992
Summary: A field crew of four people will map (by foot and boat) the rocks deposited in ancient (2,500 to 1,900 million year old) basins. These rocks will also be assessed for their economic potential. The field work will also involve the collection of water, moss and lichen to determine levels of contaminants as part of the northern contaminants study funded by the Arctic Environmental Strategy....

Principal Investigator: Nogoita, Teodor Gheorghe
Licensed Year(s): 1992
Summary: The team will study permafrost, ice and crystal formations, moss and lichen chromatography and human adaptation to cold....

Principal Investigator: Fahselt, D.
Licensed Year(s): 1992 1991 1990
Summary: The Researcher will compare the levels of enzyme variation from populations of umbilicate species from the Arctic as well as from the southern limit of their ranges in southeastern USA. The objective will be to ascertain whether there is any correlation between the level of variability in enzyme patterns and latitude....

Principal Investigator: Thomas, Patricia
Licensed Year(s): 1991
Summary: The study will compare two arctic food chains, namely, lichen-caribou- wolf and lichen-caribou-human to investigate the accumulation and transfer of Polonium-210 and Lead-210. Background levels of radiation will be measured by collecting samples of lichen, caribou, wolf and human placenta....
