Process studies

KEOPS2 (Kerguelen Ocean and Plateau compared Study) sailed in August 2011, with the aim of investigate natural Fe fertilisation of the Southern Ocean. Results from past studies (KEOPS1 and CROZEX) have raised new questions which will be focus of KEOPS2.

FeCyclesII sponsored by NIWA New Zealand (P.Boyd, PI) investigated the natural cycling of micronutrient iron and other trace elements in relation to carbon and nutrient biogeochemistry, more information is provided in the metadata form.

PINTS – primary Productivity induced by Nitrogen and Iron in the Tasman Sea. This research voyage studied iron bioavailability, sources and its biogeochemical cycling in the surface waters of the Tasman Sea, other trace metals that can act as co-limiting factors on primary productivity were also measured. Results from this voyage will thus improve our understanding on the parameters controlling primary productivity in the Tasman Sea and the biological response to relevant climate change scenarios. See  voyage summary for more details.

Three international science projects were accommodated on the NB Palmer cruise 0901. The project associated with GEOTRACES is DynaLiFe-‘Shedding Dynamic Light on Iron Limitation. The PI of the whole cruise was Stan Jacobs. See  cruise report for more information.
