Abstract

Within the framework of the EU-funded BENGAL programme, the effects of seasonality on biogenic silica early diagenesis have been studied at the Porcupine Abyssal Plain (PAP), an abyssal locality located in the northeast Atlantic Ocean. Nine cruises were carried out between August, 1996 and August 1998. Silicic acid (DSi) increased downward from 46.2 to 213 muM (mean of 27 profiles). Biogenic silica (BSi) decreased from ca. 2% near the sediment-water interface to
