Cruise Inventory Information
| Long name | RRS Discovery (74E3) cruise D207 |
|---|---|
| Short name | D207 |
| Objectives and Narrative |
1. To make measurements of the flow of deep and bottom waters passing eastward from the Weddell-Enderby Abyssal Plain to the Southern Indian Ocean via deep topographic gaps to the northeast and southeast of the Kerguelen Plateau. Specifically, to recover the two main current meter arrays deployed during Discovery 200 - an array of 10 moorings (42 current meters) and 2 bottom pressure gauges in the main gap between Crozet and Kerguelen, supplemented with a mooring in the deep cleft immediately west of Crozet Island, and a further 5 moorings (13 current meters) set in the Princess Elizabeth Trough between the Kerguelen Plateau and Antarctica.
2. To use a range of tracers, including the CFCs 10, 11, 12, 113, inorganic nutrients, dissolved oxygen and both oxygen and hydrogen isotopes (including meltwater content) to assist in partitioning the deep throughflow into its constituent watermasses, and to track the onward incursion of the AABW plume into the Indian Ocean. 3. To make discrete measurements of CO2 partial pressure in seawater, total seawater CO2 content and appropriate measures of biological activity throughout the cruise track as a BFOS/PRIME component of the BAS Antarctic Special Topic, and as a necessary determinant of WOCE. 4. To monitor a suite of discontinuous and continuous environmental variables throughout the cruise, including bathymetry from PES, XBT and ADCP, multimet, wave recorder, and thermosalinograph, and where possible to locate the major ocean frontal zones in this sector of the Southern Ocean. 5. To use a range of satellite-derived ice and weather intelligence where possible and appropriate. 6. To obtain water samples for heavy-metal analysis by Dr Frew. |
