This work has been supported by NSF Grant OCE-9216891, ONR Grants N00014-961-0832 and N00014-96-1-0836, and by the P. P. Shirshov Institute of Oceanology Russian Academy of Sciences. Michael Gregg (University of Washington) suggested the inclusion of this work to the TOGA COARE IOP planners and provided the opportunity to collect measurements during the R/V Moana Wave COARE IOP-3 leg. Vadim Pelevin (P. P. Shirshov Institute of Oceanology) provided for the testing of the equipment during the Atlantic cruise of R/V Academic Mstislav Keldysh from June to August 1992. We thank Peter Hacker for useful discussions of the work. The ORSTOM/Noumea group SURTROPAC rendered substantial assistance in the preparation of the apparatus. The assistance of the crew of R/V Moana Wave was crucial for success of the project. Calibrations of the temperature and conductivity sensors and the flow channel measurements were performed by William Drummond and Joseph Hopkins, respectively (The Johns Hopkins University Applied Physics Laboratory).
