Habitats and Distribution Patterns of Marine Luminous Bacteria in the Western Baltic Sea
Abstract Numbers of luminous bacteria were counted at three stations of the brackish water ecosystem of the western Baltic Sea from July 1985 to July 1986. Additional samples were taken during three cruises from stations at the North Atlantic Ocean, the Norwegian Sea and adjacent marine areas. — In...
