AMAP Project Directory

AMAP Project Directory

The AMAP Project Directory (AMAP PD) is a catalog of projects and activities that contribute to assessment and monitoring in the Arctic. The Arctic Monitoring and Assessment Programme (AMAP), is a working group under the Arctic Council, tasked with monitoring and asessing pollution, climate change, human health and to provide scientific advice as a basis for policy making.

The directory, which is continously updated, documents national and international projects and programmes that contribute to the overall AMAP programme, and provides information on data access as well as a gateway for the AMAP Thematic Data Centres.

Other catalogs through this service are ENVINET, SAON and SEARCH, or refer to the full list of projects/activities.

1. Radionuclide levels in caribou of northern Alaska in 1995-96

Caribou (Rangifer tarandus) were sampled (1995-96) from a mortality event near the Project Chariot site (NW Alaska), the location of a radiotracer experiment in the 1960’s, and reference sites. Radionuclide levels in muscle and bone and the cause(s) of the mortality were determined due to concerns of local residents. Bone gross alpha mean activity (n = 65) was 130.0 Bq/kg, and varied significantly (< 0.01) from 73.3 to 168.0 Bq/kg among locations. Bone and muscle gross beta mean activity was 510.4 and 9.78 Bq/kg. Bone strontium-90 mean activity (n = 58) was 137.8 Bq/kg. Muscle potassium-40 mean activity (n = 65) was 183.0 Bq/kg, and significantly varied from 76.0 to 104.4 Bq/kg by location. Muscle cesium-137 mean activity (n = 65) was 6.67 Bq/kg, ranged significantly from 0.74 to 15.6 Bq/kg by location, and increased with increasing body condition score. Bone potassium-40 mean activity ranged from 18.9 to 47.4 Bq/kg, and muscle strontium-90 ranged from 8.89 to 20.0 Bq/kg. Radionuclide concentrations were at expected levels and low in some cases as compared to Canadian caribou studies.
