Hallands Vadero is located in the outer part of Laholm Bay. Sampling interval covered 1989-1997. Previously, during the 'Eutrophication Project', phytoplankton was monitored at a close by station 1980-1986. At station Anholt E high frequency sampling started in 1998. Frequency of sampling is 20-25 times per year, with a lower intensity during the winter months. Simultaneous biological sampling is stored in BIOMAD at the Department of Systems Ecology.
