4 INTRODUC TION During 1970 the Department of Oceanography, Oregon State University, continued its program of shore sampling of ocean temperatures and salinities along the coast of the Pacific Northwest. Observations for 1960 through 1969 are contained in eight Data Reports which are listed under references. The data in this report were collected at seven stations. Table 1 lists the station names and locations, sampling sites, and names of the observers at each station. The assistance of these observers is greatly appreciated. PROCEDURE The original goals of the shore sampling program were to obtain basic information about the distribution of temperature and salinity along the coast and to aid in monitoring offshore conditions. Detailed analysis of the early data showed that we can classify Oregon coastal waters into several types according to the major processes that affect them (Pattullo and Denner, 1965). These results led us to modify the sampling program to provide us with more detailed data. In 1970 data were taken daily, and generally at high tide. Except as noted in Table 1, sampling sites were located at points exposed to the open ocean where the influence of fresh water runoff was minimal. Temperatures were read to the nearest 0. 1C with a calibrated thermometer. The observations are considered accurate to approximately ± 0.2C. Most salinity data were computed from hydrometer readings and tables (Zerbe and Taylor, 1953). Hydrometers were calibrated against an inductive salinometer which has an accuracy of about ± %o (Brown and Hamon, 1961). The accuracy of salinity determined by a corrected hydrometer is about ± 0. 2%o determined by running replicate samples on an inductive salinometer. Newport salinities were bottled samples run on an inductive salinometer. Table II lists chronologically all the observations taken at each coast station Table III is a summary of monthly means, maxima, minima, and numbers of observations for each station. All times are Pacific Standard Time (+8) except those from April to October 1970 when Daylight Standard Time was in effect. Observations at Depoe Bay were dropped in 1970 and an attempt to establish Garibaldi as a shore station failed. No data were received from the Umatilla Reef Lightship.

5 2 Figures 1 through 7 are plots of the temperature and salinity data appearing in Table II. A light line is used in the graph to represent the yearly mean of the plotted values. The cyclic appearance of some of the data results from the samples being taken at the same time each day. Future data will be taken at high tide. REFERENCES Brown, N. L. and B. V.
