| Short name | PO311 |
| Objectives and Narrative |
Between the 24th April and 26th May 2004 Plymouth Marine Laboratory in collaboration with scientists from NIWA, New Zealand, Laboratoire Arago, France and University of East Anglia conducted a two-ship exercise using RRS Charles Darwin (see Charles Darwin cruise CD156) and RV Poseidon to test the hypothesis that:
The supply of, and the interaction between iron and phosphorous control biological activity and fluxes in the subtropical North Atlantic. An experimental area in international waters to the west of the Canary Islands was selected following an intense period of vertical and horizontal mapping by the Charles Darwin. Using SF6 as a tracer for amended waters, two separate experiments were performed: The first (5th - 15th May) involved the addition of 20 tonnes of anhydrous monosodium phosphate at 10 m depth over an area of approximately 25 km2, centered at 27.8degN 23.3deg; The second experiment was conducted following a mid-cruise return by the Poseidon to Tenerife between 16th May and 22nd May, at 27.5degN 22.5degW. 5 tonnes of acidified iron sulphate were added over the first 12 hours, then following a brief recovery period, 20 tonnes of phosphate added over the top of the iron. Measurements of nutrient chemistry, gas exchange and biological activity were monitored prior to and after deployment (IN stations) of the fertilised patches relative to several (OUT) control stations. |
