Description
Summary:While the R.R.S. Discovery II was refitting in Simonstown, a remarkable profusion of a red water-bloom was observed in Simons Bay. The sea close inshore was strongly discoloured, large areas appeared blood-red. These were often sharply marked off from other areas in which the sea was of a more normal greenish hue. Motor-boat runs indicated that the red water extended along the greater part of the east coast of Cape Peninsula on July 15 and 16, 1934. Similar phenomena were observed during a previous commission, once early in June 1930 on entering Table Bay from the north, and on several occasions in False Bay.
