Freshwater TDC

In addition, freshwater and terrestrial contaminants datasets have been compiled in the SynCon database. International data centres for ozone/UV, arctic ocean acidification, permafrost and other key AMAP-relevant data exist and their use is encouraged.

AMAP Thematic Data Centres compile data from relevant monitoring and research activities and make them available under strict conditions that protect the rights of data originators. AMAP TDCs are located at established centres with appropriate expertise and facilities for conducting the types of international data handling required. For more information, please visit the main AMAP website.

Below are projects that have specified Freshwater TDC as one of the data repositories for the AMAP Project Directory. To see the full list of AMAP Thematic Data Centres, see the AMAP TDC list.

1. Spatial trends in loadings and historical inputs of mercury inferred from Arctic lake sediment cores

1. To determine the depth profiles of mercury (Hg) and lead (Pb) as well as manganese (Mn) and iron (Fe) in fifteen dated Arctic sediment cores over a three year period. Mercury is the main focus. 2. To quantify geographical trends in fluxes of the mercury and its enrichment factors in Nunavut, NWT, Nunavik, and Labrador. To link mercury findings with those of paleolimnological indicators, POPs, as well as indicators of biogeochemical processes of manganese and iron, all of which are obtained from the same cores, or cores from the same sites whenever possible. 3. To complement existing data on mercury in Arctic sediment cores with data generated over a much wider latitudinal and longitudinal range than previous work in order to provide a better understanding of Hg in Canada North. 4. Secondary to Hg, to provide loading data for Pb which may help elucidate the understanding of Hg pathways and sources.
