Thalassiosira scotia, sp. nov.: observations on a phytoplankton increase in Early Austral Spring North of the Scotia Ridge
The dominant species in an early spring phytoplankton increase in characteristically antarctic waters north of South Georgia Island is described as Thalassiosira scotia G. Fryx. et Hoban and compared to related species in the South Atlantic, such as T. antarctica Comber and T. austratis Peragallo. F...
