SHARK - National environmental monitoring of Grey seal in Sweden since 1989

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. 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 seals is performed by counting seals from land, ship or airplane.
