PurposeResearch
ObjectivesThis cruise was a companion to Cory 8/03 and was designed to include some recovery of instrumentation deployed during cruise 8. The work was generally aimed at achieving a better understanding of the dynamics of the circulation processes of the Western English Channel. Specifically, this cruise aims to better characterise the extent and nature of density-drive and seasonal jet-like circulations which may act as a direct and rapid pathway for the transport of material. The previous cruise found an extensive bloom of the dinoflagellate Gyrodinium Aureolum (now renamed Kareni Miximotoi). The nature of the flows associated with fronts and the structure of the bottom frontal structures is of primary interest.
1. Characterise the hydrographic structure associated with frontal regions and investigate the transport pathyways by use of towed undulating CTDs.
2. Characterise the biological transport indicators by species identification.
3. Recover ARGOS drifting buoys.
4. Recover moorings (ADCP and thermistor chain).
