Holligan, PM, Charalampopoulou, A, Hutson, R (2010). "Seasonal distributions of the coccolithophore, Emiliania huxleyi, and of particulate inorganic carbon in surface waters of the Scotia Sea". JOURNAL OF MARINE SYSTEMS, 82(4), 195-205.

Data on the surface distributions of chlorophyll, particulate inorganic carbon, biogenic silica and coccolithophores for a section in the western Scotia Sea (Drake Passage) made in December 2006 are presented. The relationships between PIC, total coccoliths and water-leaving radiance (as measured by MODIS) are largely consistent with published observations for warmer waters. However, for water temperatures <4 degrees C, the estimated values of PIC per coccolith are relatively low. Examination of satellite images of the Scotia Sea for the austral summer 2006/7 and for mid-January 2003 to 2008 indicates considerable temporal (seasonal and interannual) variability in the surface distribution of PIC. Physical processes (advection and cross-frontal exchange) appear to be important in determining year-to-year differences. Current satellite algorithms may give significant overestimates of coccolith PIC for the colder waters of the Southern Ocean. (C) 2010 Elsevier B.V. All rights reserved.
