SHARK - National Grey seal monitoring in Sweden since 1989

OBIS and EurOBIS

Data from Swedish environmental monitoring of abundance of Grey seal. Swedish monitoring of Grey seals started in 1989. The monitoring program was initiated by the Swedish Environmental Protection Agency and later the Swedish Agency for Marine and Water Management took over the responsibility and financing of the program. The monitoring is performed by the Swedish Museum of Natural History. Data is stored in the database SHARK, hosted and maintained by the Swedish Meteorological and Hydrological Institute. Monitoring of seal is performed by counting seals from land, ship or airplane.
