BOTTENLINSER OCH NÄRSALTSDYNAMIK I LAHOLMSBUKTEN / Bottom Lenses and Nutrient Dynamics in the Laholm Bay
The linkage between (1) bottom dynamics, i.e. where areas of erosion (E), transportation (T) and accumulation (A) prevail, (2) lenses, i.e. fine highly moveable material-living and dead, inorganic and organic, recent and resuspended-that can be found on shores and on generally harder deposits predominating on E- and T-bottoms, and (3) the flux of nitrogen, which is the most limiting nutrient element in marine environments, has been studied in the Laholm Bay. This preliminary report presents some new findings about the amount of nitrogen in the lenses during the period from Sept. 1983 to June 1984. Data from seven surveys show that the total flux of nitrogen connected with the lenses would be in the range of 4 000 to 10 000 tons per year. This is a remarkable sum compared to, e.g. the total discharge via the tributaries, which is 4 000 tons N per year. “Complete abstract not presented.”
