Bacterial cell carbon content, cell volume and concentration at various sampling stations in the Swedish part of the Baltic Sea. Sampling is performed with a rosette sampler or Niskin bottles attached to a wire. Bacterioplankton has been monitored 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. Monitoring is performed by Umeå University. Data is stored in the Swedish Ocean Data Archive (SHARK) database by the Swedish Meteorological and Hydrological Institute.

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.

An imaging flow cytometer, the Imaging FlowCytobot, was used to investigate phytoplankton abundance and diversity in a fjordal system on the Swedish Skagerrak coast. Samples of 5 mL were collected approximately every 25 minutes. An automated winch was used to move the IFCB to different depths. Chlorophyll fluorescence of individual organisms was used to trigger the camera in the instrument. Several thousand images were collected in each sample. Automated image analyses was used to analyse the images produced to identify and count cells of different plankton taxa.

Data from Swedish environmental monitoring of abundance of Harbour seal. Swedish monitoring of Harbour seals started in 1988. 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.

Data from Swedish environmental monitoring of abundance of Ringed seal. Swedish monitoring of Ringed seals started in 1995. 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 ringed seal is performed by counting seals in transects from airplane.
