Deep-Sea Research II 49 (2002) 1765–1786 Biogenic silica production rates and particulate organic matter distribution in the Atlantic sector of the Southern Ocean during austral spring 1992 B. Qu!eguinera,*, M.A. Brzezinskib aCentre d'Oc!eanologie de Marseille, Laboratoire d'Oc!eanographie et de Biog!eochimie, Parc Scientifique et Technologique de Luminy, UMR CNRS 6535, Case 901, F-13288 Marseille Cedex 9, France bDepartment of Ecology, Evolution and Marine Biology, and the Marine Science Institute, University of California, Santa Barbara, CA 93106, USA Abstract Several of the components of the silicon cycleForthosilicic acid (Si(OH)4), biogenic silica (BSi), and biogenic silica production rates (rSi)Fhave been investigated, together with the distribution of particulate organic carbon (POC), particulate organic nitrogen (PON) and carbon primary production (rC), on a series of transects across three sub- systems in the Atlantic sector of the Southern Ocean (61W): the seasonal ice zone (SIZ), the permanently open ocean zone (POOZ), and the southern boundary of the polar frontal zone (PFZ). The study was conducted in Spring 1992 as part of the European SO-JGOFS cruise aboard the R.V. Polarstern. High BSi concentrations (maximum: 11.7 mmol Si l1) were recorded in late November at the southern border of the PFZ.
