ObjectivesATSR satellite validation cruise. The cruise was divided into 2 legs: Leg 1 primarily focussed on ATSR satellite validation and Leg 2 was planned around the recovery of Netherlands Institute of Sea Research (NIOZ) moorings. Throughout the cruise real-time measurements of the air-sea fluxes of momentum, sensible heat, latent heat and CO2 were made, in addition to the usual mean met parameters.

The main aim of Leg1 (Seychelles to Seychelles) was to achive as many ATSR satellite overpass validations as possible with the SISTeR radiometer. In addition 5 APEX floats were deployed in support of the ARGO programme and 2 XBT equatorial sections were made.

During Leg2 (Seychelles to Durban) the key objective was to recover an array of seven moorings, on a section across the Mozambique Channel roughly at it narrowest part, which had previously been deployed by NIOZ. Further ATSR overpass validations were achieved and 2 more XBT sections were made.
