1. Lakes; Chemistry

Annual measurements of physical, chemical, and biological variables are taken in small to medium sized, mostly minimally disturbed lakes, situated across the country. Of the 110 lakes that are part of the Trend Station Lake monitoring programme, 20 are situated in AMAP area. The main aim of the monitoring programme is to document long-term changes related to global or regional change and human-generated stressors. To complement the Trend Station Lake monitoring programme, national lake surveys provide spatial data needed to determine regional patterns, and coupled with time-series data, changes in surface water quality. The National Lake Survey (the Surveillance Stations, re-sampled stations) programme for lake water quality, started in 2007 and results in data of all Swedish lake conditions. Each year some 800 new lakes are sampled to determine biological, chemical and physical conditions; lakes are resampled at 6 year intevals. 4824 lakes are sampled in the country during a six-year sampling cycle, with 1270 situated in AMAP area. The variables included in the Trend Station Lake monitoring programme include water chemistry, fish, phytoplankton, macrophytes, zooplankton, and benthic invertebrates, whilst and National Lake Survey is focused solely on water chemistry.

2. Biodiversity and adaptation strategies of Arctic coastal marine benthos

The objectives of the project are to assess: 1) the present biodiversity of benthos in Arctic coastal ecosystems (White Sea, southern Barents Sea, Pechora Sea), and indicators for changes caused by disturbances; 2) the adaptations to the Arctic climate for some benthic key-species, the additional influence of disturbance and the sensitivity of the key-species to additional stress from disturbances; 3) the geochemical background of the regions Research activities: Annual missions by ship for sampling water, sediments and macrobenthos. Biodiversity analysis of macrobenthos in sediments in laboratories in Murmansk (MMBI) and Tromsø (Akvaplan-Niva), ecophysiological analyses in laboratories of St. Petersburg (ZISP), Yerseke (NIOO-CEMO) and Pisa (UN), analyses of pollutants in laboratories in Moscow (MSU), Nantes(UN) and Pisa (UP), geochemical analyses of water and sediment in laboratories of Moscow (MSU) and Barcelona (UB).

3. Thuleundersøgelse-1997

The benthic marine environment in Bylot Sound off the Thule Air Base was contaminated with ca. 1.4 TBq 239,240Pu (ca. 0.5 kg) in 1968. The site was revisited August 1997 aiming mainly at a new inventory estimate and at quantifying transfer to benthic biota.
