Directory entires that have specified Canadia, Arctic Islands as one of the geographic regions for the project/activity and are included in the AMAP, ENVINET, SAON and SEARCH directories. Note that the list of regions is not hierarchical, and there is no relation between regions (e.g. a record tagged with Nunavut may not be tagged with Canada). To see the full list of regions, see the regions list. To browse the catalog based on the originating country (leady party), see the list of countries.

1. Assessment of spatial and temporal patterns of HCH isomers in the arctic environment

In order to assess the spatial and temporal patterns of the a-, b- and g-isomers of hexachlorocyclohexane (HCH) in the arctic biotic and abiotic environment, it is proposed that: (1) concentrations and ratios of HCH isomers be compared over time in air, water, seals, beluga, polar bears and seabirds to determine any shifts in isomeric ratios and how those shifts interrelate among the various media, and (2) concentrations and ratios of HCH isomers be compared spatially in the abiotic and biotic media and reasons for any patterns explored.

2. Greenland Right Whale

The ecology of the Greenland Right Whale is studied using the historical information from written sources from Dutch archives. The Spitsbergen and Davis Strait populations of the Greenland Right Whale were so heavily hunted that they are almost exterminated now in the northern waters. The whale bones on the beaches of Arctic islands are the archaeological evidences of this exhausting hunt. Very often whaling logbooks, crew statements and lists of catch figures are the only sources of information preserved of this animal in these regions. In this project recent biological information of the animal in the seas around Alaska and historical information of the whale in the North Atlantic and Davis Strait is used to reconstruct the migration, distribution and ecological behaviour of the Greenland Right Whale in the North Atlantic Ocean.

3. Temporal trends of persistent organic pollutants and metals in ringed seals from the Canadian Arctic

The objective of this project is to study long term temporal trends of persistent organic pollutants and mercury in ringed seals from the Canadian arctic. The project rationale is that there are previous results for POPs and mercury in ringed seal tissues for many locations. Furthermore there may be regional differences in temporal trends due to geographical differences in POPs and mercury in marine waters and food webs within the Canadian arctic. It is relatively cost efficient to return to the same locations for additional samples using the same sampling and anlaysis protocols are were used in previous studies (see AMAP and Canadian Assessment Reports). Samples are being collected with the help of hunters and trappers organizations in each community. During 2000-01 samples are being collected at Resolute, Arctic Bay and Pond Inlet. The study will also analyse samples collected recently (1998/99) from Pangnirtung, Arviat and Grise Fiord. Results will be compared with previous data which the Principal Investigator generated in the 1980's and early 1990's. Preliminary results will be available in mid-2001.

4. New Persistent Chemicals in the Arctic Environment

The objectives of this project are A) to determine coplanar polychlorinated biphenyls (PCBs), polychlorinated naphthalenes (PCNs), brominated diphenyl ethers (BDPEs), chlorophenolic compounds and chloroparaffins in air from arctic monitoring stations; and B) to search for other "new" chemicals in the arctic environment, not currently monitored by Canada's Northern Contaminants Program (NCP) but of potential concern based on known persistence, extent of usage and toxicology.
