| Abstract |
The relationship between chlorophyll-a concentration and bacterial abundance was analysed in a permanent station in coastal waters of Alboran Sea (SE of Spain), during a summer period. Bacterial abundance and chlorophyll-a concentration dynamics showed a positive empirical relationship in sub-surface waters, but no relationships were found in deep waters. The estimation of bacterial size determined as biovolume, showed bigger cells in deep samples as a feature independent of phytoplankton production. This suggested that bacterial production was mainly linked to the growth of phytoplankton healthy cells in surface layers and with other processes as physical dynamics, nutrient supply from sediments and other allochtonous carbon sources in bottom samples. |
