PurposeResearch
Objectives1. To survey potential coring sites by 3.5 kHz reflection profiler and bottom photography.
2. To take suites of kasten and box cores, spanning as large a water-depth range as possible, from four principal areas on the 20W transect.
3. To X-ray and sample the cores in detail, providing samples for water content, carbonate and organic carbon content and chemistry, grain-size, radiochemistry, dating, mineralogy, micropalaeontology and stable isotope analysis.
4. To sample cores on behalf of other workers and keep archive cores.
5. To squeeze or centrifuge samples from box cores for extraction and analysis of pore waters for nutrients, oxygen and redox sensitive species.
6. To determine oxygen profiles in the surface few centimetres of box cores using oxygen electrodes with a micromanipulator system.
7. Take CTD/transmission-fluorescence casts with 12 x 10-litre Go-Flo bottles at each coring area plus casts between areas and on the runs out and back.
8. To conduct basic-BOFS measurements on the water bottle samples including temperature and salinity, nutrients, oxygen, DOC, POC & N, pigments and total suspended matter.
9. To maintain underway current measurements via ADCP and EM logs, fluorescence/transmission and Temperature/Salinity measurements on continuously pumped flow, and determine nutrients (NO3, PO4, SiO2) on samples taken from that flow.
10. To recover, refurbish and redeploy sediment trap moorings, split, preserve and perform any necessary immediate analysis on trap samples.
11. To sample the water column via in situ pumps and water bottles for analysis of natural uranium series radionuclides.
