Analysis of Water Mass at Pacific Ocean Station VICTOR, 1964-65.
Analysis of 271 Nansen casts obtained during four 3-week cruises at ocean weather station (OWS) VICTOR (34N, 164E) between March 1964 and June 1965 showed that seasonal influence extended from the surface to 150 meters. The local central water mass was more saline than Western North Pacific Central...
