| Popis: |
The paper presents results of long-term investigations on primary production and chlorophyll a concentrations at two stations in the Southern Baltic (in the Gdańsk Deep and in the Bornholm Deep). The data show increasing trends in the annual primary production and mean chlorophyll a contents. A mean increase in the annual primary production within the recent years is estimated at 1-2% per year. |
