The data were acquired during the Bay of Biscay Boundary (TripleB) project and we acknowledge the cooperative attitude of Dr. Hendrik van Aken for allowing us to deploy our instruments during the cruises of his project. Triple B is partially supported by a grant from the Netherlands Organization for the advancement of scientific research (NWO). We thank the crew of RV Pelagia for assisting in the deployment and recovery of the instrumentation, and the reviewers for their constructive comments. J.G. has been supported by a European Community TMR research fellowship under Contract MAS3-CT97-5047.
