During the WELOC-77 cruise, May 21 - June 18, 1977, hydrographic and light beam transmission measurements were simultaneously made in situ off the coast of Peru on R/V WECOMA. Temperature, salinity and light
transmission data are listed for standard depths, and their vertical profiles are also presented.
Dai 1 y temperature and sa 1 in i ty conditions measured in the surf at Agate Beach, Oregon, are given and summarized by 15 day periods, with the range, mean and standard deviation of each period indicated. Conditions in 1970 are briefly compared to those observed in 1968 and...
