Abstract

The RRS James Clark Ross sailed from Port Stanley in the Falkland Islands on 28 April and arrived in the UK on 1 June 2004. The main objective of the cruise was to determine the trophic state of the planktonic ecosystem with respect to large scale patterns in the ambient concentrations and supply to the surface waters of inorganic nutrients and of dissolved organic matter. Nitrogen fixation using 15N methodology was determined at all stations sampled with rates ranging between 0.4 and 8.3 nmol L-1d-1 in the South Atlantic Gyre; between 0.2 and 2.2 nmol L-1d-1 in the North Atlantic Gyre and reached maximum rates of 17.0 nmol L-1d-1 within the area of equatorial upwelling.
