INTRODUCT ION
During February, March and April 1974, the interdisciplinary Coastal
Upwelling Ecosystems Analysis experiment known as JOINT-I took place over
the continental shelf and slope near Cabo Corveiro in the NW African upwelling region.
As part of the field program, Oregon State University
made a series of repeated hydrographic surveys from R/V GILLISS along
latitudes 21°2O'N and 2l°4O'N (Fig. 1).
The more northerly line was the
site of the current meter mooring and meteorological buoy array maintained
during the same period by Oregon State University in cooperation with the
Deutsches Hydrographisches Institut, Hamburg.
This report contains the
complete set of contour plots of hydrographic section and anchor station
data obtained by OSU.
The low-pass filtered time series of current and
wind measurements from each OSU mooring are also included.
A summary of the CTD and STD data and the calibration of the probes
used during JOINT-I are reported by Barton, Stevenson and Gilbert (1975).
From computer listings of the complete data set, vertical sections were
contoured by hand.
The depth interval between observations was always
less than 5 meters and usually about 2 meters.
Smooth contours were drawn
to pass through the observed or interpolated depth of selected isosurfaces
at each station.
Numerous large inversions of salinity and temperature
created a considerable problem in contouring.
Although consistency in
interpretation was the aim, there are undoubtedly other equally possible
configurations of the isopleths in some cases.
The contoured sections
are subject to aliasing by internal waves and tides, but it is felt that
the distributions have not been greatly distorted by short period fluctuations, at least on the shelf.
The 24-hour anchor station in 100 m of
3
water tends to support this supposition (see page 15).
A standard bottom
profile was used for all sections resulting from repeated occupations of
the same line.
In the displayed sections contours are drawn at regular intervals of
1°C in temperature, 0.1 o/oo in salinity, and 0.1 units of sigma-t.
sionally, extra contours are indicated and labeled.
Occa-
A dashed portion of
an otherwise solid contour indicates uncertainty in its positioning.
Sta-
tion numbers are indicated at the top of the sections and distance away
from the shoreline is indicated at the bottom.
The position of the OSU current meter array is shown in Fig. 1.
The
operating periods of the various moorings are illustrated together with the
times of the OSU hydrographic surveys in Fig. 2, and in Fig. 3 the vertical
arrangement of current meters along 2l°40'N is shown.
The current meter
and anemometer data were recorded at 5 or 10 minute intervals.
time series were filtered to produce hourly series.
The resultant
In this form they are
reported by Pillsbury, Bottero, Still and Mittelstaedt (1975).
In the
present report, the hourly series were further filtered with a symmetrical
cosine filter spanning 121 hours with a half power point at 40 hours to
suppress diurnal and higher frequency oscillations.
Use of the low-pass
filter shortens the time series by 2 1/2 days at each end.
Wind observations were recorded at Rhododendron, Urbinia and Forest
Fern.
A complete record for the whole length of the experiment was not
obtained at any one site.
For this reason, the two shelf wind series
(Rhododendron and Urbinia) were joined at the end of the Urbinia record
to provide one continuous series.

during JOINT-I.
Each bar represents a current meter.

over 12 days of overlap between the two records showed no significant differences.
A 5-day gap in the joined record existed because of a failure
of the direction sensor in the Urbinia anemometer, which was corrected
when the instrument was serviced on 17 March.
The bad observations were
replaced by wind data from the buoy Lisa, deployed by the NOAA Pacific
Marine Environmental Laboratory.
Lisa was situated within 1 km of Urbinia.
Data from each mooring are presented in order of distance from the
coast.
Mooring name, position, water depth, length of data series, and
depths of the instruments are listed for each mooring.
The vector series
of low-passed measurements from all the current meters on the mooring are
displayed on one page (except for Foxglove) at half day intervals beginning
at midday or midnight GMT.
The vector wind series is shown at the head
of the page for the current record length.
The vector series are followed
by scalar series plots of the northward (v) component and the eastward (u)
component of the current at all observation depths.
Also included in the report are sections of mean temperature, salinity
and sigma-t along 2l°40'N, based on mean profiles calculated from the repeated occupations of each standard station position, and sections of the
mean northward (v) and eastward (u) components of velocity, based on the
overall record mean from each current meter regardless of record length.
The mean currents are additionally displayed as depth profiles for each
moon nq.
