Port Stanley - UK

This was the third in the series of six AMT cruises funded by a NERC Consortium Grant. 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 principal scientist was Prof. Patrick Holligan from the Southampton Oceanograpy Centre.

Extra ship time meant that AMT14 could take a more westerly route into towards the centre of the northern gyre than on previous AMT cruises.

The main objective of the cruise was to determine the trophic state of the planktonic ecosystem with respect to large scale patterns in the the ambient concentrations and supply to the surface waters of inorganic nutrients and of dissolved organic matter.

A NERC grant also enabled the first measurements of the standing stock and rates of formation of biogenic minerals (diatom silica and coccolithophore calcite) to be made on an AMT cruise. These measurements were used to provide a better understanding of the control of the biological pump.
