Beschreibung:
<p>Studies were made on the phytoplankton and chlorophyll a content of waters in the Gerlache and Bransfield Straits of Antarctica during December 1958 and January 1959. Rich communities of diatoms, such as Thalassiosira, Conscinodiscus, Eucampia, and Synedra, and the Chrysophycean Phaeocystis were observed at numerous stations in the Gerlache Strait and the western part of Bransfield Strait. Dinoflagellates were very scarce in this region. Antibiotic activity of the plankton was associated with Phaeocystis. The eastern area of Bransfield Strait, near the tip of the Antarctic Peninsula, was almost devoid of phytoplankton at all depths. Chlorophyll a determinations agreed in general with observations on the abundance of phytoplankton. Chlorophyll a ranged up to about $27 mg/m^3$ of water, and the amount of pigment in surface waters was inversely related to total depth of the water.</p>
