Depth, temperature, salinity, and sound velocity profiles taken from R/V ROGER REVELLE in the North Pacific from 2004-06-03 to 2004-06-17 (NCEI Accession 0001933)

This dataset is a collection of 15 CTD casts taken in the North Pacific in early June, 2004. The purpose of the cruise was the deployment of acoustic sources and hydrophone arrays as part of the North Pacific Acoustic Laboratory experiment. CTD casts were performed at each of the transceiver location as well as on the acoustic path between the transceiver moorings. The purpose of obtaining this CTD data was to derive sound speed profiles for the interpretation of acoustic tomographic data.
