Cruise Inventory Information
| Long name | RRS Charles Darwin (74AB) cruise CD86 |
|---|---|
| Short name | CD86 |
| Objectives and Narrative |
The major aims of the cruise were to collect data at stations along the OMEX transect regarding the composition of the watercolumn, to establish the salinity, temperature, nutrient and oxygen conditions and distribution of these parameters in the watercolumn and in the near bottom waters and surface sediments, and to recognize, discriminate, and sample bottom nepheloid layers in the watercolumn by application of transmissometer, nephelometer and watersampling simultaneous with CTD in the Goban Spur area.
Furthermore to carry out sediment sampling by piston- and boxcoring, and to carry out porewater sampling in boxcores for studies of early diagenesis, in relation to in-situ measurements of oxygen profiles and electrical resistivity in the bottomwater and the surface sediments by deployment of the TROL (Temperature Resistivity Oxygen) lander. Benthic fluxes of oxygen and nutrients were measured in situ with the NIOZ BOLAS (Benthic Oxygen Lander System) lander, and by sediment deck incubation of boxcores to similarly obtain benthic fluxes of oxygen and nutrients across the sediment water interface. Additional boxcore samples were taken to establish the benthic macro- and meifaunal community structure in the near surface sediments. |
