Acknowledgments
We are grateful to IPEV, his director G. Jugie and his chief of operations on board, Y. Balut, for providing this opportunity to train students on the Marion Dufresne R/V. We thank J. Lefevre, Captain of the Marion Dufresne, for agreeing to host us on his ship.

We thank the chief scientists on the SEDICAR and PICABIA cruises, J.F. Bourillet (IFREMER) and J.L. Turon (Univ. Bordeaux 1) for integrating the University at Sea in their scientific activities on board. Many thanks to all the scientists embarked on the cruise for their availability and their interaction with the students.

We particularly appreciate the participation of the speakers, who took the time to explain their research, to answer our questions, and talk to the students.

Last, but not least, the University at Sea is very thankful to the entire crew of the Marion Dufresne for providing us with the best "working" environment possible. Special thanks to the restaurant and the forum... and to Agnes for organizing the "Great International Choir Contest"!
