PurposeResearch
ObjectivesThis cruise was undertaken jointly under the NERC Core Strategic Programme of the SOC George Deacon Division (BICEP: Biophysical Controls on Export Production) and the EU project OASIS (Oceanic Seamounts: an integrated study) project co-ordinated by Dr Bernd Christiansen, Universitat Hamburg (EVK3-CT-2002-00073-OASIS). The general aim of the cruise is to undertake a range of physical, chemical and biological investigations on and around Seine and Sedlo Seamounts. Specific objectives for the cruise include: 1) The recovery of two current meter moorings from Seine Seamount (originally deployed from FS Poseidon in March 2004); 2) To make underway observations of upper water column currents and zooplankton migrations (using ADCPs and 10 kHz echosounder); 3) To assess water column hydrography, primary production and biogeochemistry through deployments of a CTD and water bottle rosette; 4) To assess the biochemistry and biogeochemistry of suspended particulate matter by the use of SAPS (stand alone pumping system); 5) To investigate the taxonomy, ecology and biogeochemistry of zooplankton communities using a multiple opening and closing net system (MOCNESS); 6) To make photographic (stills and video) observations of the seabed and it's larger fauna (megabenthos) using the SOC SHRIMP system (Seabed High Resolution Imaging Platform).
Discovery sailed Vigo 30 June 2004. Operations around Seine Seamount were carried out 6-18 July and around Sedlo Seamount 20-26 July. Discovery docked Govan 1 August 2004.
