Description

Spatial distribution of different types of marine sediments in the Southern Ocean (modified from Diekmann, 2007). The greenish area south of the Polar Front shows the extension of the subpolar opal belt where sediments have a significant portion of silicous plankton frustules. Sediments near Antarctica mainly consist of glacial debris in any grain size eroded and delivered by the Antarctic Ice.

  • (1) Calcarous ooze/mud,
  • (2/3) biosiliceous/mud,
  • (4) coarse lithogenic sediments,
  • (5/6) lithogenic sand/mud.
