Cruise Inventory Information
| Long name | RRS Charles Darwin (74AB) cruise CD85 |
|---|---|
| Short name | CD85 |
| Objectives and Narrative |
UK contribution to OMEX to quantify the biologically mediated cross-slope exchanges and vertical fluxes of biogenic material in the region of the Goban Spur.
Main Tasks: 1. 2 x SeaSoar survey to investigate hydrographic structure of region 2. Net sampling to study the data and night vertical distribution of macroplankton and micronekton. 3. Observe patterns of acoustic back-scatter using ship-borne ADCP; and 'sea-truthing' of data using LHPR net samples. 4. Asses marine snow distribution and abundance, using sediment trap moorings, cameras and large water bottles. 5. Evaluate cross-slope changes in phytoplankton and microzooplankton. |
