Phytoplankton of the Olaf Prydz Bay (Indian Ocean, East Antarctica) in February 1969

Paper received 10 December 1979. Qualitative and quantitative composition of phytoplankton of the Olaf Prydz Bay (Indian Ocean, East Antarctica) was determined on the basis of 49 samples collected at 34 sampling stations during the period from the 15th to 24th February 1969. Altogether 59 taxa of al...

Qualitative and quantitative composition of phytoplankton of the Olaf Prydz Bay (Indian Ocean, East Antarctica) was determined on the basis of 49 samples collected at 34 sampling stations during the period from the 15th to 24th February 1969. Altogether 59 taxa of algae were identified — among them: 57 taxa of the class Bacillariophyceae, 1 species of the class Chrysophyceae and 1 genus of the class Dinophyceae. Species occurring most frequently and most abundantly in the Olaf Prydz Bay are diatoms: Thalassiothrix antarctica, Chaetoceros criophilus, Nitzschia curta, Rhizosolenia alata. At some stations Chaetoceros dichaeta occurred in great numbers. A decrease in phytoplankton numbers in the areas south of 67 S is associated with the lack of neritic algae among dominant species.
