Cruise Inventory Information
| Long name | RRS Discovery (74E3) cruise D181 |
|---|---|
| Short name | D181 |
| Objectives and Narrative |
1. Quantify the circulation of the Biscay region northeast of 41N, 30W with a box of full depth CTD casts at about 75km intervals along the sections. Sampling will include nutrients (nitrates, phosphates and silicates), chlorophyll 'a' and bacterial counts. Vertical net samples will also be taken during selected CTDs for BOFS.
2. Conduct SeaSoar trials to test various modifications to the fairing, fish and depressor, designed to improve its performance and increase its maximum depth and duration of tow; also to test improved editing and display software. 3. Run SeaSoar sections within the CTD survey box to quantify variations of the T/S characteristics of newly ventilated winter Mode water. 4. Run a SeaSoar section from 47N to 60N along the BOFs line at 20W to examine the latitudinal variation of mixed layer depth, the horizontal statistics of eddy and frontal activity, and the variability of upper ocean properties (temperature, salinity, oxygen and chlorophyll 'a'). 5. Continuously sample surface parameters to examine the spatial (and temporal) variability of temperature, salinity and fluorescence. 6. Deploy and recover a short term mooring (4 weeks) to observe internal tidal wave propagation off the Celtic shelf. 7. Deploy a two year trial mooring close to 6. 8. Recover two moorings from the shelf edge off the north coast of Spain. 9. Deploy sediment traps at 47N, 20W for BOFS. |
