Coccolithophyceae of the Southern Ocean

There are 24 species of Coccolithophyceae that are commonly found in the Southern Ocean.

Information on the COI barcoding status of these species is presented in the table below.
MODE
A		 All available COI barcodes for this taxa group (collected from any ocean and/or without geo-referencing):
  • Of the 24 total species, 7 of these species (29%) have COI barcodes (from this or any ocean).
  • There are a total of 325 "any ocean" COI barcode records available for this ocean and taxa group.
  • All available taxa group COI barcodes will be included in the Mode A downloads.
    • MODE
    B    		 Regional COI barcodes for this taxa group (includes only those collected in the Southern Ocean region):
  • Of the 24 total species, 0 of these species (0%) have Southern Ocean-collected COI barcodes.
  • There are a total of 0 "Southern Ocean-collected" COI barcodes available for this taxa group.
  • In the map to the right, Red Stars show sampling locations of the COI barcodes in the Mode B download.
    • Uncoded
    Species    		 Of the 24 total species in this region, 17 species do not have any COI barcodes (from any region).

     Barcoding progress summary for the Southern Ocean region, out of a total of 24 possible species:
    • There are COI barcodes for 7 species ( 29% coverage ), of which 0 species have barcodes sampled inside this region ( 0% coverage ).
      •
    • There are 12S barcodes for 0 species ( 0% coverage ), of which 0 species have barcodes sampled inside this region ( 0% coverage ). 
    • There are 16S barcodes for 13 species ( 54% coverage ), of which 1 species have barcodes sampled inside this region ( 4% coverage ).
    • There are 18S barcodes for 17 species ( 70% coverage ), of which 0 species have barcodes sampled inside this region ( 0% coverage ).
    • There are 28S barcodes for 9 species ( 37% coverage ), of which 1 species have barcodes sampled inside this region ( 4% coverage ).
