Cruise Inventory Information
| Long name | RRS Discovery (74E3) cruise D200 |
|---|---|
| Short name | D200 |
| Objectives and Narrative |
1. To make direct measurements of the flow of deep and bottom waters passing eastwards from the Enderby Abyssal Plain to the Southern Indian Ocean via deep topographic daps to the northeast and southeast of the Kerguelen Plateau. Specifically, to lay two main arrays of current meters with 10 moorings (42 current meters) and 2 Bottom Pressure Recorders in the main gap between Crozet and Kerguelen, supplemented with a mooring in the deep cleft immediately to the west of Crozet Island, and a further 5 moorings in the Princess Elizabeth Trough between the Kerguelen Plateau and Antarctica.
2. To extend two of the moorings of the main Crozet-Kerguelen array up into the near surface layers to aid the subsequent SWINDEX investigation into the interactions of the Agulhas and Antarctic Circumpolar Currents. 3. To use a range of tracers including the CFCs 10, 11, 12, 113, inorganic nutrients, dissolved oxygen and oxygen and hydrogen isotopes (indicating meltwater content) to partition the deep throughflow into its constituent water masses and to identify these as to source using a widely-spaced set of upstream measurements. 4. To make discrete measurements of CO2 partial pressure in seawater, total seawater CO2 content (TCO2) and appropriate measures of biological activity throughout the cruise-track as a BOFS/PRIME component of the BAS Antarctic Special Topic, and as a necessary determinant of WOCE. 5. To make measurements of biogenic dimethylsulphide (DMS) and its precursor (DMSP) at regular intervals throughout the ship's track, as a component programme of the BAS Antarctic Special Topic. 6. To monitor a suite of discontinuous and continuous environmental variables throughout the cruise, including bathymetry from PES, XBT ADCP, multimet, wave recorder and thermosalinograph. 7. To use a range of satellite-derived ice and weather intelligence where possible and appropriate. All these objectives were met in full with the exception of number 4. |
