%X A diverse range of biological and chemical oceanographic properties and processes were measured in shallow NW shelf waters surrounding the Harriet A production platform in September 1995. Shelf waters were characterised by low plankton biomass levels, very low dissolved nutrient concentrations, relatively high water column primary and bacterial production rates, rapid nutrient uptake rates and rapid rates of water column particle turnover. While concentrations of dissolved organic carbon (DOC) and P04 in PFW were elevated ca. 100-fold relative to ambient concentrations in shelf waters, daily discharge fluxes are small relative to local water column stocks. In contrast, PFW discharges of NH4 were very large relative to regional water column stocks. Because local plankton are strongly N-limited, this NH4&#x2212;N was very rapidly taken up (depletion times
