Abstract: Distribution and composition of benthic marine algae were studied at 4 stations in the Ellis Fjord (Iat. 68° 35' and 68° 38' E; long. 77° 50' and 78° 15' S) Vestfold Hills, Antarctica. Algae were collected through drilled hole in sea ice from May to December 1983 and during summer in the intertidal zone. Of the 14 algal species recorded from Ellis Fjord and Vestfold Hills, Antarctica brown algae Himantothallus grandifolius and Desmarestia menziesii were abundant near the mouth of the Fjord, but apparently absent inside the Fjord. Red algae Palmaria decipiens and Phyllophora antarctica were the dominant species of the region. Porphyra endiviifolium occurred in the upper littoral zone while Urospora penicilliformis and Enteromorpha bulbosa occurred in the intertidal rock crevices and furrows. Monostroma hariotii was present both in the intertidal pool and in infralittoral zone. Decrease in nitrate concentration was related with the luxuriant growth of U. penicilliformis during December, which was evident from the increase in photosynthetic activity resulting into high dissolved oxygen and pH of the water.
