Biometry of detached Emiliania huxleyi coccoliths along the Patagonian Shelf
The coccolithophorid Emiliania huxleyi is a key contributor to pelagic calcite production and exists as a variety of morphotypes throughout the ocean. Limited information is currently available as to the relative distribution or hydrographic conditions which each of these morphotypes favour. Poulton and co-authors examined the relative distribution of detached coccoliths of the different morphotypes along the Patagonian Shelf in December 2008. The two morphotypes had distinctive distributions, with morphotype A in warm waters with low nutrients and morphotype B/C in cold waters with high nutrients. Morphotype B/C dominated the large-scale bloom that was present along the Patagonian Shelf and the B/C morphotype is presumably common throughout the Southern Ocean.
