SHARK - National marine environmental monitoring of zooplankton in Sweden since 1979

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 should be sampled and analyzed according to the HELCOM COMBINE Manual - Part C Annex C7 Mesozooplankton (helcom.fi/media/publications/Guidelines-for-monitoring-of-mesozooplankton.pdf). However, deviations from the manual might occur. Information about the program and the methods are available in Swedish at the website of Swedish Agency for Marine and Water Management, havochvatten.se/vagledning-foreskrifter-och-lagar/vagledningar/ovriga-vagledningar/undersokningstyper-for-miljoovervakning/undersokningstyper/djurplankton-trend--och-omradesovervakning.html
