Rappel des Objectifs
1. Biochemical and compound specific stable isotope analyses of surface layer microplankton to
study coupling between the photic zone and the deep-sea hydrothermal vents.
2. Compound specific stable isotope analyses (fatty acid, amino acids and carbohydrates) to
study the trophic structure of the hydrothermal vent ecosystem located at 9 and 13 North on the
East Pacific Rise.
3. Life history strategy of hydrothermal vent organisms including reproductive elements.
Travaux réalisés
The collection of a wide range of material from the hydrothermal vent sites and the phototrophic
zone.
Exploitation à terre
All samples now await analysis in the UK and no details regarding the results are currently
available. It is intended that collaborations developed during the cruise will continue over the
summer during the analysis of samples and interpretation of data.
1. Francoise Gaill and Florence Pradillon - reproductive studies of Riftia,Paravinella, Alvinella
and Galitheids.
2. Aline Fiala - nutritional studies of hydrothermal vent bivalves.
Commentaires
A successful cruise!
