GROWTH OF THE ALGAE ISOCHRYSIS-GALBANA AND TETRASELMIS-SUECICA IN WATER AND SEDIMENT ELUTRIATE SAMPLES FROM THE GERMAN BIGHT

Surface water samples and sediments were sampled during the Bremerhaven Workshop at 9 locations on a transect from the inner German Bight to the Dogger Bank. Two species of algae were grown in the water samples and sediment elutriates prepared from the sediments. In both types of samples algal growth over 5 d was highest in the inshore samples and a graded response in growth was observed over the 5 inshore stations.
