-
Data collected within various monitoring programmes and surveys. Standard zoobenthos techniques using benthic grabbers and species analyses for counts and weights on species level.
-
The national monitoring program was initiated by the Swedish Environmental Protection Agency and is now financed by the Swedish Agency for Marine and Water Management. Monitoring is performed by Stockholm University, Umeå University, Swedish Meteorological and Hydrological Institute and Gothenburg University. Data are stored in the Swedish Ocean Archive (SHARK) by the Swedish Meteorological and Hydrological Institute (SMHI).
-
Data collected within various monitoring programmes and surveys. Standard quantitative phytoplankton techniques following HELCOM MONAS guidelines. Counts and sometimes biovolumes on species level.

The survey existed since 1968. It is carried out every 3 years in the north eastern Atlantic. The year after the Atlantic survey, a mackerel egg survey is conducted in the North Sea. The survey creates a basis for the stock assessment of Atlantic and North Sea mackerel and management plan for Atlantic horse mackerel. The historical MEGS data is expected to be uploaded in 2015-2016. The group responsible for the survey is WGMEGS.

The Fish predator/prey database (stomach database) contains data covering 11 countries. A total of 217 399 stomachs are reported in the North Sea data. Eight predator species were analysed and 854 NODC prey codes have been reported
-
Monitoring of species richness, abundances of all macrobenthic species, biomass, sediment grain size, temperature and salinity
-
Monitoring of species richness, abundances of all macrobenthic species, biomass, sediment grain size, temperature and salinity. The experiment was designed to study long-term changes in community structure in response to global change (climatic change) and local anthropogenis pressures (e.g. eutrophication).

This CD contains part of the data from the Benthos Information system, the database of the Monitor Task-group of the NIOO.
-
This time series on species composition and biomass or abundance of macrozoobenthos in the Belt Sea and the Baltic proper provide data from 1979 till 2005 as part of the HELCOM monitoring
