PurposeResearch
ObjectivesThis cruise was in 2 legs. Leg 1: 01 - 21 Jun 2002; Leg 2: 22 Jun - 11 Jul 2002.
Aims:
1. Examination of the structure of the mean flow around and over the Mascarene Ridge.
2. Investigation of the decadal-timescale changes in the water masses in the vicinity of the Mascarene Ridge.
3. Assessment of the energy fluxes, and mixing produced by, internal waves in the vicinity of the Mascarene Ridge.
4. Bathymetric survey of parts of the Mascarene Ridge and surrounding area.
5. Calibration of the ENVISAT saltellite sensors measuring the temperature (AATSR) and colour (MERIS) of the ocean surface.
6. Investigation of biogeochemical properties (nutrients, phytoplankton, zooplankton, biogenic gases, CFC tracers and light levels) around the Mascarene Ridge, and their relationship to the structure of the mean flow.
7. Measurement of heat fluxes and winds near the air-sea interface, and the airflow disturbance around the ship.
