Directory entires that have specified Arctic Ocean 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).

21. The Seasonal Cycle of Organochlorine Concentrations in the Canadian Basin

In September 1997, the CCGS Des Groseillers was frozen into the permanent ice-pack and started a year-long science program drifting across the southern Canada Basin. This program provided a unique opportunity to carry out a "vertical" food-chain study in a seasonal context to learn how the physical and biological systems couple to produce contaminant entry into the food web (Figure 1). "Vertical" components included the water and ice, particles, algae, zooplankton (sorted by trophic level), fish and seal.. The interpretation of contaminant data collected during SHEBA will provide information about the relationship between seasonal ice formation and melt, seasonal atmospheric transport and water column organochlorine concentrations in the Canada Basin. In addition our contaminant sampling program was integrated within a larger science plan where other SHEBA researchers studied the physical and biological properties of the water column. This means that contaminant distributions can be interpreted and modeled within the full context of physical, chemical and biological processes, and of atmospheric and oceanic transport mechanisms.

22. The high latitude oceans in the climate system, with special emphasis on their role in the global carbon cycle

The scientific objectives of this project is to add information that helps elucidate the role of the Arctic Mediterranean Seas (Arctic Ocean and Nordic Seas) in the climatic system of the Northern Europe. More specifically it has the following aims: - To assess the heat and carbon dioxide fluxes over the air-sea interface in the Barents Sea and elucidate the effect this has on the formation of Arctic Ocean intermediate waters and associated carbon fluxes. - To assess the temporal variability of the fresh water distribution in the Arctic Ocean, both river runoff and sea ice melt, and the affect this has on the outflow of fresh water to the regions of open ocean deep water formation (the Greenland, Iceland and Labrador Seas). - To assess the mixing of upper and intermediate waters along the East Greenland Current that gives the properties of the overflow into the North Atlantic Ocean and thus add to the driving of the thermohaline circulation. This also contributes to the sequestering of anthropogenic carbon dioxide.
