From July 1982 to October 1985, two current meter moorings were deployed in the northeastern Pacific at 42 deg N and 28 deg N, 152 deg W. Between six and ten vector-averaging current meters and Aanderaas were placed on each taut-wire sub-surface mooring, and these were exchanged about every twelve months. The purpose was to measure the vertical and temporal structure of low-frequency motions in the eastern Pacific basin. To interpret the current meter data in terms of dynamic principles, the vertical structure of the density gradient in the entire water column is required. Current meters measure only the temperature. In July 1983, a CTD survey was carried out in support of the mooring program during the redeployment cruise of the moorings. A 600 km equatorial, triangular pattern of stations was occupied around each mooring, with CTD casts from the surface to the ocean floor. Interspersed with the CTD stations were 1700m XBT stations Sippican model T-5. Three XBT-CTD calibration stations were also done. The CTD data are presented in this reports.
