SLAW R HYDROGRAPHY of Oregon Estuaries Prior to June 1956 By Wayne V. Burt Office of Naval Research Contract Nonr 1286(02) Project NR 083-102 Reference 56.2 n Ors ' ./0; A•-` _ June 1954 SCHOOL OF SCIENCE OREGON STATE COLLEGE Corvallis, Oregon HYDROGRAPHT OF OREGON ESTUARIES PRIOR TO JUNE 1956 by Wayne V. Burt Data Report No. 2 Office of Naval Research Contract Nonr 1286(02) Project NR 083-102 Reference 56-2 June 1956 Wayne V. Burt Oceanographer ABSTRACT Most of the readily available unpublished hydrographic data for which was collected prior to June 1956 have been Oregon Estuaries tabulated. Data presented. Data USC & GS are not on water temperature salinity and velocity are collected by the Navy Hydrographic Office and the included INTRODUCTION The data presented in this report consists of hydrographic information for ten Oregon estuaries. Most of these data were collected under the present contract with the assistance of personnel and equipment from the Shell Fish Laboratory of the Oregon Fish Commission under the direction of Mr. L. D. Marriage. Other data were collected by the Corps of Engineers. The locations of the estuaries are shown on the map on the cover. STATION LOCATION Most of the sampling stations are listed by some land mark. In dddition the approximate distance from the ocean is given for each station. These distance are in nautical miles up the main channel of each estuary. The ocean is considered to begin at the outer end of the jetties or the outer edge of the mouth of the estuaries. The locations of stations in the Columbia River are shown on Figure 1. DATA Temperature. Most of the temperature data was obtained by placing an ordinary laboratory thermometer in the metal sampling bottle after the sample had been taken aboard. The rest of the temperature data was obtained with the Chesapeake Bay Institute conductively Temperature Indicator. The accuracy of all samples should lie between 0.1 and 0.5 °C. Salinity. Most of the salinity data were obtained from specific gravity reading made with salinity hydrometers. The rest of the salinity data was obtained with the Chesapeake Bay Institute Conductively Temperature Indicator. The accuracy of all samples should lie between 0.1 and 0.5 0/00 Current Velocity was determined with the current drag (D. W. Pritchard and Wayne V. Burt, an Inexpensive and Rapid Technique for obtaining current profiles in Estuarine Waters, Journal of Marine Research, Val. x, No. 2, 1951, pp 180-189). The accuracy should be between 0.1 and 0.2 knots for these surveys.

S. Army Corps of Engineers. (Columbia River Salinity Charts, MC-3-6/I, 2, 3, and 4 and B-2-41/194, B, C, and D, by R. E. Hickson.) The Data were presented as specific gravity. It was originally presented without correction for temperature or the calibration of the hydrometers. Temperature corrections have been applied to the data which has also been converted to salinity in parts per thousand, 0/60. A constant correction factor of minus 1.1 o/oo, based on the calibration data for the hydrometers, been applied to all of these data presented below. The location of the stations is shown on figure 1. Distances listed are the approximate number of nautical miles up the channel from the ocean. All of the stations were located in or near the main channel except A, C, J, I, Z, CC, DD and EE.
