BODC Cruise Metadata Report for RRS Charles Darwin (74AB) cruise CD85

Introduction

This report collates information from the BODC cruise inventory and oceanographic databases. It presents

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.
