INTRODUCTION
This report is an intermediate step in analyzing part of the hydrographic data from the 1972 Coastal Upwelling Experiment (CUE) off the coast
of Oregon.
It presents the author's interpretation of the vertical distribution of temperature, salinity and sigma-t along lines occupied on
hydrographic cruises by R/V Yaquina during CUE.
Hydrographic observations
collected from R/V Oceanographer during CUE (Halpern and Holbrook, 1972)
are not included in this report.
Data reports for each of the CUE hydrographic cruises have been
pub-
lished (Anon., 1972 a-e; 1973 a-c; Halpern and Holbrook, 1972). The diagrams presented here will be of interest to the other CUE participants and
also to other oceanographers studying Oregon coastal waters.
SUMMARY OF THE OBSERVATIONS
Hydrographic observations during the Coastal Upwelling Experiment were
R/V Yaquina and R/V Oceanographer, and by
two groups, one at Oregon State University and one at NOAA's Pacific
Oceanographic Laboratory, respectively. Although observations from
Oceanographer are not presented in this report, it is appropriate to inmade mainly from two ships,
clude them in the Summary of Observations.
Almost all of the observations from Yaquina were made with a Geodyne
conductivity-temperature-depth (CTD) system; Oceanographer observations
were made with a Bissett-Berman salinity-temperature-depth system.
The
observational and data processing procedures are described in the data
reports.
Oregon.
Both ships occupied stations in a grid adjacent to the coast of
nine hydrographic cruises on Yaquina and
In all, there were
three on Oceanographer during CUE.
Dates for each of the cruises are shown
in Table 1. A portion of the grid was occupied on each cruise. On some
of the cruises, one or more lines of stations were occupied more than once.
Normally, stations in the grid were occupied sequentially along lines
approximately normal to the shore. Most of these lines were spaced at
intervals of five minutes of latitude between 44°35'N and 45°OO'N (Figure 1);
stations were at intervals of six minutes of longitude.
Oceanographer lines
extended from the shore to 125°W; Yaquina did not usually go out beyond
124°42'. On the later cruises station density was increased near shore.
METHOD OF PREPARATION AND PRESENTATION
The distributions of temperature, salinity and sigma-t in this report`
were hand-contoured by the author from computer listings of CTD data.
The
listings resulted from the processing of the CTD data as described in the
2

coastal upwelling experiment.
data reports. The depth interval between observations was always less
than five meters.
For each line of stations, three tables were constructed, showing the
depths of particular isotherms, isohalines and isopycnals, respectively.
All sections were plotted on a common scale. The salinity or sigma-t
section was normally drawn first, as these parameters almost always increased monotonically with depth. The depths of a particular isogram were
plotted on the section; these points
then connected by a smooth
were
curve. In other words, the depths of isograms at station locations is as
observed. Only between stations is there any interpolation from the data.
After the distributions of salinity and sigma-t had been drawn for a section,
the depths of isotherms were plotted. Temperature inversions were frequent,
and ambiguities were normally resolved by consideration of the T-S
properties of the water, and the general tendency for isotherms to be
parallel to isohalines. In some cases, there was very little evidence to
choose one interpretation over another. In almost all of these cases,
differences were small enough that a qualitative description of the distributions would not distinguish between the alternate versions. Distributions of sigma-t were plotted from the listings of sigma-t for each
station, not from the contoured distributions of temperature and salinity.
When the plotted distributions were finalized, they were traced onto
printed sections showing the standard bottom profile along the line of
stations. The deepest observation of each CTD cast is shown by -L. Contours
at the specified contour intervals are shown as solid lines. Dashed lines
indicate an extra contour. Dotted lines show there is more uncertainty
than usual in part of a contour. Station numbers are given along the top
of the section; these allow easy reference back to. the data reports. On
some sections, the deepest observation occurs at depths greater than the
standard bottom profile. In these instances, navigation error resulted in
the station being located in deeper water. We did not attempt to redraw
the bottom profile for every occupation of the same line, but used the
standard bottom profile.
Aliasing due to internal waves and tides is present in the distribu-
tions presented here. Our knowledge of these phenomena is not adequate to
warrant attempting to remove such aliasing. Also, it is believed that such
aliasing does not result in gross distortion of the distributions.
Vertical distributions of temperature, salinity and sigma-t are
shown for eight different lines. Seven of these are along parallels of
latitude - namely 44°35'N, 44°40'N, 44°45'N, 44°50'N, 44°55'N, 45°00'N,
and 45°12'N.
The other runs seaward from Depoe Bay; Oregon, it is the
Depoe Bay Line that has traditionally been occupied on hydrographic cruises
of Oregon State University. The line along 44°40'N nearly coincides with
the traditional Newport Hydrographic Line. Most of these lines were
occupied on more than one occasion.
The vertical distributions are presented in order of the cruises, and
within each cruise (with one exception) in chronological order. This has
the advantage of making it easier to see the effect of location. Some
users may be more interested in repeated occupations of the same line. For
their benefit, Table 2 shows the page numbers of distributions by location
as well as by cruise.
