North Pacific Acoustic Laboratory CTD Data: R/V Moana Wave Cruise IW98 (August 15-30, 1998) and R/V Melville Cruise IW99 (June 18-July 3, 1999)

Abstract

Two research cruises were conducted in the summers of 1998 and 1999 as part of the North Pacific Acoustic Laboratory (NPAL) project. The cruises objective was to test the theory that predicts acoustic fluctuations from the internal wave sound speed or temperature fluctuations. Here we discuss the in situ profile measurements of temperature, salinity, and derived sound speed taken with conductivity temperature density (CTD) instruments dropped off the side of the ships as they steamed between the NPAL Acoustic Thermometry of Ocean Climate source off Kauai and a billboard receiving array on Sur Ridge off Point Sur, California. The first cruise, IW98, was aboard the University of Hawaii research vessel Moana Wave. The second cruise, IW99, was aboard the R/V Melville.
