Wecoraa cruise W8702B was conducted in February 1987 as part of the pilot study
for the Coastal Transition Zone project.
CTD observations were made in the
coastal transition zone off northern California between 37.5°N and 4l.5°N.
Stations were planned along three alongshore transects, at distances of 60, 90
and 150 km from the coast.
Strong winds (with speeds greater than 35 kts)
prevented the completion of the survey, but 38 stations were completed suècess—
fully.
They .were concentrated along lines 60 and 90 km from the coast.

ABSTRACT
Wecoma cruise W8702B was conducted in February 1987 as part of the
pilot study for the Coastal Transition Zone project. CTD observations were
made in the coastal transition zone off northern California between 37.5°N and
4l.5°N. Stations were planned along three alongshore transects, at distances
of 60, 90 and 150 km from the coast. Strong winds (with speeds greater than 35
kts) prevented the completion of the survey, but 38 stations were completed
successfully.
They were concentrated along lines 60 and 90 km from the coast.
Maximum sampling depth at most stations was 500 m. Temperature and salinity
were measured at all stations; light transmission was also measured at the
first 23 stations.
This report presents vertical profile plots and
tabulations of data at selected depths for each station, and vertical sections
of temperature, salinity and density anomaly for the two long alongshore
sections.

INTRODUCTION
This was the first of three mapping cruises designed to determine the
general character of the mesoscale flow field in the Coastal Transition Zone
off northern California during the winter and late spring of 1987.
All three
cruises were intended to have the same basic sampling pattern (shown in Figure
1) covering an alongshore extent of about 450 km.
designed to consist of three modular units (A,B,
The cruise track was
and C, south of Pt. St.
George, Cape Mendocino and Pt. Arena, respectively), each of which would take
about three days to complete, and thus provide a synoptic mesoscale survey of
each unit.
Each module included alongshore transects at about 90 and 150 km
from shore, and cross-shore transects extending out 60 km from the coast.
The combination of three modules yields two continuous alongshore sections
(Lines I and II, 150 and 90 km from shore respectively) each about 450 km
long, and a discontinuous alongshore transect about 60 km offshore.
On each
cruise, we planned to make closely spaced CTD casts to 500 m on the outer
transects of the southern modules; it is in this region that seaward jets and
narrow filaments of cold surface waters had been observed previously
et al., 1986; Kosro and Huyer, 1986).

On each cruise, we operated a 300 kHz
acoustic-Doppler current profiler continuously and obtained continuous
underway surface temperature and salinity data.

The ship departed from Newport, Oregon on the morning of 16 February
1987, and headed straight out to 44°4O'N, 125°30'W, where a test cast of the
CTD equipped with a 12-bottle rosette and a transmissometer was successfully
completed (Station 1, Table 1).

The ship then steamed directly south to the
We began Module A north of Cape Mendocino with Station
2 on 17 February as planned, completing Station 19 early on 20 February. As
winds had strengthened to almost 30 knots early on 20 February (Figure 3), we
temporarily broke off CTD work and steamed inshore to survey the inshore end
of Module B between Cape Mendocino and Pt. Arena.
Winds weakened later on 20
February, and we were able to complete Stations 20 and 21 on Line III, and
Stations 22 and 23 on Line II. By the middle of 21 February, wind speeds were
increasing sharply and the rosette and transmissometer were removed from the
CTD to make the package easier to handle in the rough seas. Winds continued to
increase to speeds well in excess of 30 knots (Figure 3)
were suspended entirely after Station 25.
and CTD operations
The ship steamed slowly northward
along Line II to about 40°30'N, before tacking southwestward to the northwest
corner of Module B on Line I.
On 23 February, the ship steamed rapidly
downwind along Line I while winds and seas remained too high to resume CTD
work. On 24 February, we turned to go northward along Line II; by the middle
of the day the sea had calmed enough to resume CTD operations (without the
rosette and transmissometer); we completed Stations 26-35 along Line II and
Stations 36-38 on Line III.
There was not sufficient time left in the cruise
to complete the cross-shore sections planned for the inshore portion of Module
C.
The ship arrived in port in San Francisco late on 25 February.
Personnel participating in the cruise were Michael Kosro (chief
scientist), Tim Cowles, Rich Schranim, Jane Fleischbein, Dennis Barstow, Henry
Pittock, Glenna Pittock, Ted Benson, Marc Willis and Kevin Krefft of Oregon

SAMPLING AND CALIBRATION PROCEDURES
A Neil Brown Instruments Mark Ilib conductivity-temperature depth (CTD)
probe (#2561) was used to obtain Continuous profiles of temperature and
salinity and pressure at each station.
During the first half of the cruise
(i.e., Stations 1-23), a General Oceanics rosette water sampler was mounted
with the CTD, and the CTD was equipped with a Sea Tech. Inc. 25-cm
transmissometer (#33D).
The entire package was lowered at about 45 rn/mm.
The CTD was fitted with a 1600 db pressure sensor and the fast response
thermistor was disabled and replaced in the circuitry with a precision 10 ohm
resistor.
The CTD was set to sample at its maximum rate of 32 Hz. The time
constant of the platinum resistance thermometer of the probe had earlier been
determined to be 0.235 sec (Fleischbein et al., 1987) using estimates of the
slope of the phase spectrum between the measured temperature and conductivity
as suggested by Millard, Toole and Swartz (1980).
OSU's CTD probe #2561 was calibrated for pressure, temperature and
conductivity by the manufacturer in December 1986.
Water samples were taken
from the rosette Niskin bottles at selected depths to provide in situ
calibration data. Protected reversing thermometers were mounted on one rosette
bottle.
After use of the rosette was discontinued (i.e. after Station 23), a
single Niskin bottle was mounted immediately above the CTD. No water samples
were
obtained on Stations 23-24 and 34-38.
Bottles
were tripped during the
up-cast, and the CTD data to be compared with the samples were recorded at the
actual depth at which each bottle was tripped.
Duplicate salinity samples
were drawn from selected bottles and stored in round 4-oz. glass bottles with
8
new poly-seal caps, with an additional outer seal of 'Parafjlmt.
One complete
set of the salinity samples was analyzed on a Cuildline 8400A Autosal
salinometer (OSU's #3) within three weeks (by 17 March).
Duplicates were
analyzed mainly to check those sample values which showed relatively large
differences from the CTD.
The Cuildline Autosal determines water sample
salinity with a precision of ± 0.002 and an accuracy of ± 0.003.
The
reversing thermometers have an accuracy of ± 0.02°C and were corrected using
the results of calibrations done once every 3 years at the Northwest Regional
Calibration Center.
Typically, a few CTD-sample differences are much larger than the
others, as large as several standard deviations; these usually occur in
regions of sharp vertical gradients and are eliminated from the in situ
calibration data set.
For this cruise, we eliminated 6 of the salinity
samples and two sets of thermometer readings. The remaining temperature
differences (Table 2) were within or close to the stated accuracy of the
reversing thermometers, so no temperature correction was applied to the CTD
data.
The CTD temperature was also calibrated in the laboratory at OSU in
August 1987; results of that calibration (mean difference less than 0.001°C
from the standard) confirmed that no correction was needed. The CTD pressure
at the surface prior to a cast was recorded at regular intervals during the
cruise; it always remained less than 0.5 dbar which is within the stated
accuracy of the pressure sensor (± 1.6 dbar)
applied to the CTD data.

which had been corrected for temperature and pressure effects on the cell.
The average and standard deviation of the conductivity differences (Table 2)
were within the stated accuracy of the CTD so no conductivity correction was
applied to the CTD conductivity data.
The transmissometer measures the light transmitted by a collimated
beam of nearly monochromatic (660 nm) light through a 25 cm path length,
providing an analog output of 0 to 5 VDC, corresponding to 0 to 100 %
transmission.
This output is digitized by the CTD using the full integer
range of 0 to 4095, and merged into the data stream.
The transmissometer was
calibrated in air and water by the manufacturer prior to the cruise, and the
air calibration was repeated on the ship during the cruise.
The results are
used to correct the measured voltage using the formula:
VOLTS= (AIROLD/AIRNEW) * (TVOLT - ZERO)
where VOLTS is the corrected voltage, AIROLD is the voltage output in air
obtained during the precalibration (4.741 V in this case), AIRNEW is the
voltage output obtained in air during the cruise (4.744 V in this case),
TVOLT is the measured voltage output, and ZERO is the voltage output when the
light path is completely blocked (0.0007 V in this case). The formula
TRANS = (VOLTS/5)*lO0.
was used to convert the corrected voltage to percent transmission.
CTD DATA PROCESSING PROCEDURES
The CTD data are recorded at sea on a Kennedy 9-track data logger,
with many stations on each tape.
Data logging normally begins as soon as the
CTD probe is in the water, and continues until after the probe has reached the
maximum depth.
The first step in data processing is to obtain a directory of
12
the data tape using program NBCTD3.
For each station, this directory lists
the header data, the block number in which the instrument descent begins, and
the maximum pressure.
NBCTD3 is then used to create disc files of pressure,
temperature, conductivity and transmissometer counts for each cast.
This
program also corrects the conductivity data for variations in cell geometry
due to pressure and temperature changes.
Using program CTDRED6 we then apply
the temperature, conductivity and pressure calibrations if necessary, and
check for extraneous values and extreme gradients.
recursive filter designed by R. Millard (S. Hayes,
This program applies a
pers. comm.) to the
conductivity data to remove the phase difference introduced by the finite
response time
(
T
235 msec) of the temperature sensor; this filter has the
form
C(n)
a0 C(n-l) +
(1-a0)
C0(n)
where C0(n) is the observed value and C(n) is the filtered value of the
scan, and a0
T / (T +
ti)
=
0.880 is a constant determined from the time
constant T and the time interval ti between scans.
The same recursive filter
is applied to the pressure data to reduce the digitizing noise and ensure that
the pressure data is in phase with the temperature and conductivity data at
low frequencies (<1 Hz).
Practical salinity (Lewis, 1978) is computed from
the temperature and the filtered conductivity and pressure data using standard
algorithms (Fofonoff and Millard, 1983) and a value of 42.914 to convert CTD
conductivity to conductivity ratio (Culkin and Smith, 1980).
The filtered pressure data are used to eliminate the ascending scans
caused by ship's motion.
Data collected during descent are sorted into 2 dbar
bins, and the extremes and averages of each variable are computed for each
bin.
Profiles of the temperature and salinity extremes are plotted to
13
determine whether further editing is needed, and the 2 dbar mean temperatures
and salinities constitute the processed data.
When editing appears to be
necessary, the original data files are examined in detail; data points that
are rejected are replaced by linearly interpolated values, and the files are
reprocessed using CTDRED6.
The processed data files containing integral pressure, and
temperature, conductivity, salinity, transmission, etc.
,
average
are archived.
These
files are used to calculate other parameters of interest such as potential
temperature (theta), potential density anomaly (sigma-theta), specific volume
anomaly, geopotential anomaly, sound velocity,
etc. ,
from the new equation of
state of sea-water (UNESCO, 1981) using standard algorithms (Fofonoff and
Millard, 1983).
In this data report we show only profile plots of
temperature, salinity, sigma-theta and light transmission vs. pressure, and
tables of temperature, salinity, sigma-theta, specific volume anomaly,
geopotential anomaly and light transmission at selected pressures.
DATA PRESENTATION
The body of this data report presents vertical profiles of
temperature, salinity and the density anomaly, sigma-theta for all 38
stations.
For the first 23 stations, a second plot shows the vertical
profile of light transmission, with the temperature and salinity profiles
repeated to facilitate comparisons among variables.
For all stations, data
from the upper 500 dbar are shown to the same vertical scale; for station 22,
which penetrated to 1000 dbar, a second set of plots shows data from the
entire cast.
14
For each station, we also present tabulations of selected
at standard depths.
Header information for each station includes:
STA NO
Consecutive station number
LAT
Latitude in degrees and minutes north of the equator
LONG
Longitude in degrees and minutes west of the Greenwich meridian
DATE
Day, Month, Year
TIME
Universal Time (Greenwich Mean Time)
PROBE
Serial number of the CTD probe
DEPTH
Sonic depth in meters, corrected according to MatthewsTables.
The data table for each station gives values of temperature in °C (TEMP),
practical salinity (SAL), potential temperature (POTEN TEMP), density anomaly
in kg/m3 (SIGMA THETA), specific volume anomaly in 108 m3/kg (SVA),
geopotential anomaly (dynamic height, DELD) in dynamic meters, and light
transmission (TRN) in percent.
SUMMARY OF RESULTS
Because of strong winds and high seas, we were able to complete less
than half of the CTD casts in our sampling plan. Nevertheless, we obtained
reasonably good alongshore coverage along Lines II and III, and the vertical
distributions of temperature, salinity and sigma-theta along these lines are
shown in Figures 4-9.
Along Line II, the surface temperature was rather uniform, ranging
only between 11.3 and 12.6; surface salinities were somewhat lower in the
north than in the south. Both the thermocline and the halocline were roughly

and centered at about 100 m (Figures 4,5).
Deeper waters showed some
alongshore gradation in both temperature and salinity, but these seemed to
have a compensatory density effects, i.e. warmer waters were higher in
salinity and cooler waters were lower in salinity, so that the deeper
alongshore density gradients were generally small (Figure 6).
The surface temperature along Line III had stronger alongshore
gradients (Figure 7), particularly between Stations 36 and 37, where surface
temperatures were 10.4 and 11.6 C, respectively. There was an even larger
difference between Stations 21 and 36, but this may be partly the result of
temporal aliasing.
The cold surface water at Station 36 was relatively high
in salinity (S=33.12) compared to the neighboring stations (S<32.8 at Sta. 21
and S<33.0 at Sta. 35), so there are associated alongshore density gradients
north and south of this station (Figure 9). These density gradients do not
seem to penetrate to depths below the pycnocline centered at about 100 m
(Figure 9).
However, there are subsurface alongshore gradients in temperature
and salinity, with the warmest, highest salinity water occurring at Stations
21 and 36, just north of Pt. Arena, and the coldest, lowest salinity water
occurring at Stations 6 and 7 near Cape Mendocino (Figures 7,8).
Three pairs of CTD casts before and after a four-day interval of
strong winds were made at three locations on Line II just north of Pt. Arena.
In all three pairs, the temperature and salinity profiles (Figure 10) show
that the surface mixed layer is deeper and the surface temperature is colder
after the windy interval as expected. There is also a substantial change in
the structure of the temperature inversion embedded in the halocline.
The
surface salinity, however, is very nearly unchanged.
Average and standard deviations of the 38 temperature, salinity and
sigma-theta profiles (Figure 11) show the bottom of the surface mixed layer

occurs at about 60-80 m, at the top of a sharp halocline which coincides with
the upper thermocline.
The standard deviations of salinity and density
decrease with depth through this halocline, but the temperature variability is
nearly constant with depth (Figure 11). Average and standard deviations of the
T-S curves were computed after the CTD data were reordered to treat sigmatheta, rather than pressure, as the independent variable; statistics were
computed for each 0.01 kg/rn3 interval of sigma-theta.
The resulting curves
(Figure 12) show that there was considerable variation in T-S characteristics
within the survey region.
