Seasonal variation in sea level in the Pacific Ocean during the International Geophysical Year, 1957-1958

Seasonal variations in sea level derived from IGY measurements are described and compared with those previously published. These measurements confirm the earlier descriptions, which were baaed on observations from gauges attached mostly to continental coastlines. That is, in low latitudes in each hemisphere, sea level is high at the end of summer. There is a zonal band of high sea level from about the Equator to 40° N in September while in comparable southern latitudes sea level is low...

Ocean currents above the continental shelf off Oregon as measured with a single array of current meters

Ocean currents were measured with meters moored above the Oregon continental shelf during four periods of about 25 days each----in July, September, and October 1965 and in February 1966. The data are described with histograms and progressive vector diagrams. Velocity variations having a frequency lower than one cycle in two days were associated with similar variations in wind in the alongshore direction...

Present research, facilities and staff

This report summarizes the present status of research work at the Depart­ment of Oceanography, Oregon State College, under Contract Nonr 1286(02) Project NR 083-102 with the Office of Naval Research. After this date quarterly progress reports will be submitted

The seasonal oscillation in sea level

On the basis of all available tide gauge records, bathythermograma, and Nansen bottle casts, we have compiled, on a global scale, monthly departures of recorded and steric sea levels from their annual means. The steric fluctuation is defined in terms of the seasonal fluctuation in specific volume. The results are given in the appendices and in three charts, together with error estimates. In general, the departures are comfortably above the uncertainties introduced by year to year variations and by the effects of local topography...

Research activities during the period 1 January through 31 March 1961

This report summarizes the research conducted during the first quarter of the calendar year 1961 by the Department of Oceanography, Oregon State University, under Contract Nonr 1286(02) Project NR 083-102 with the Office of Naval Research

A compilation of observations from moored current meters and thermographs. Vol. 1. Oregon continental shelf, July 1965-February 1966

This is the first data report of a program designed to study physical processes in Oregon shelf waters by means of moored instrument arrays. Various statistics and plots of smoothed data are presented for time series of current velocity and of temperature. Data were collected in July, August, September, and October of 1965 and in January and February of 1966

A compilation of observations from moored current meters and thermographs. Vol. 5. Oregon continental shelf 31 July-21 September 1969

Observations from an instrument array moored over the continental shelf off Oregon from 31 July to 21 September 1969 are presented. Temperature, current and wind observations were obtained every 20 minutes. First order statistics, histograms, progressive vector diagrams and time series plots are presented. Supplementary wind observations at Newport are also described. It is recommended that wind observations be part of a future coastal current observational program and that thermographs be placed in positions with a large temperature gradient

A compilation of observations from moored current meters and thermographs. Vol. 3. Oregon continental shelf, May-June 1967, April-September 1968

A summary of one phase of a direct observational program conducted in the coastal region off Oregon is presented. The measurements were made primarily on the continental shelf during most of the coastal upwelling season (May and June 1967; April through September 1968). The principal measurements were time series of horizontal current velocity and temperature fields; these observations were made with an array of moored, recording meters. Supplementary measurements of hydrographic variables, wind, atmospheric pressure, and mean sea level were also made

A compilation of observations from moored current meters and thermographs (and of complementary oceanographic and atmospheric data). Vol. 2. Oregon continental shelf, August-September 1966

A summary of one phase of a direct observational program conducted in the coastal region off Oregon is presented. The measurements were made primarily on the continental shelf in late coastal upwelling season (August and September 1966). The principal measurements were time series of horizontal current velocity and temperature fields; these observations were made with an array of moored, recording meters. Supplementary measurements of hydrographic variables, wind, atmospheric pressure, and mean sea level were also made. The emphasis of this data report is on the graphical and tabular display of first-order statistics. Limited descriptive remarks are made in order to provide some interpretation for these initial results. More thorough analyses and discussions of the observations are expected to follow from this stage of analysis. In brief, this set of measurements in the coastal upwelling frontal zone indicates the flow field: is highly variable on the time scale of tidal-like motions to that of motions with several-day periods. ii) has a southerly mean at a depth of 20 meters (in the "surface layer"). iii) has a northerly mean at a depth of 60 meters (at the base of the "permanent pycnocline"), has a marked response to variations in the wind field on the time scale of several days. Recommendations regarding future observations and analyses are made
