Cruise Inventory Information

Long name FS Poseidon (06PO) cruise PO328
Short name PO328
Objectives and Narrative Overall objectives in the POL science programme to 2007 include estimates of slope mixing and some of its oceanic effects. As part of this, objectives a) on the cruise were to make measurements to enable estimates of internal waves and their induced mixing and bottom boundary layer forms (over the West Shetland slope), and to enable the estimates to be related to context: slope, stratification, mean flow. [In the wider project, further allied objectives are: b) to derive, using 3-D fine-resolution and specialist process models for extrapolation, an estimated effect on the characteristics of water flowing adjacent to slopes with (internal-wave-induced) mixing; c) to estimate, using 3-D fine-resolution models for extrapolation, the role slope mixing and associated processes such as water mass transformation, play in cross-slope exchange of mass, heat, salt and nutrients].
Specific objectives for F.S. Poseidon cruise 328 were to (i) deploy and recover four ADCP moorings, three adjacent temperature-logger moorings and the specialist rigs STABLE, HOMER and NIOZ Lander and fast-sampling thermistor string, altogether in a ~ 7km cross near the 500m depth contour, (ii) carry out CTD (+LADCP) surveys of cross-slope centred on the mooring array and ~70 km to the east and west, (iii) carry out repeat (24-hr) CTD (+LADCP) stations, sequences of CTD (+LADCP) stations following any identified internal wave packets and record ship-borne ADCP, all for internal wave behaviour, (iv) obtain satellite images, underway surface and meteorological measurements as context information.
