ABSTRACT
Current-meter data collected at seven stations in South San
Francisco Bay, California from 1981 to 1983 are compiled in this
report. Measurements include current speed and direction, and
water temperature and salinity (computed from temperature and
conductivity). For each of the forty-two deployments, data are
presented in two forms: (1) results of harmonic analysis; and (2)
plots of tidal current speed and direction versus time and plots
of temperature and salinity versus time. Spatial distribution of
the properties of tidal currents are given in graphic form. In
addition, Eulerian residual currents have been compiled using a
vector - averaging technique.
Results of harmonic analysis indicate that the tidal cur
rents are generally bi-directional and the principal direction
depends on basin bathymetry. Current speed shows a spring/neap
variation of about a factor of two and the tide is mixed but
closer to semidiurnal than to diurnal. Eulerian residual flows
indicate the presence of a clockwise gyre in the center part of
South Bay and a counterclockwise gyre in the southern part of the
bay during the late winter period.
INTRODUCTION
The deployment of current meters and subsequent processing
and analysis of current-meter data are a part of an extensive
interdisciplinary study undertaken by the U.S. Geological Survey
to better understand the physical, chemical, and biological proc
esses that affect the San Francisco Bay estuarine system (fig.
1). Broad goals of this study are to understand the processes by
which water, solutes, sediments, and organisms interact; to quan
tify effects of river inflow, winds, and tides; and to develop
and verify various numerical and conceptual models of these rela
tions (Cheng and Conomos, 1980).
To examine hydrographic properties of San Francisco Bay,
in-situ recording current-meter stations have been established
throughout the Bay system. The current meters record current
speed and direction, and water temperature and conductivity at 2-
minute intervals for deployment periods of as much as to 30 to 40
days. Previous reports document current-meter data collected
from 1978 through 1980 (Gartner and Cheng, 1982; and Cheng and
Gartner, 1984).
The purpose of this report is to present all current-meter
data collected from 1981 to 1983 in a form useful to users. Data
are displayed graphically in the form of time-series plots and
the spatial distribution of major properties of tidal durrents
are shown. Speed and direction data have been harmonically ana
lyzed to determine the amplitude and phase of the primary tidal
constituents (harmonic constants). The harmonic constants are

used to qualitatively define the tide and may be used for tidal
predictions. Eulerian residual currents have been determined by
vector averaging the time series. All data collected during this
period were in South San Francisco Bay. A brief summary of the
field program and data processing procedures is given below.
More complete descriptions of equipment and deployment, recovery,
maintenance, and data processing procedures are given by Cheng
and Gartner (1980, 1984).
FIELD PROGRAM
South San Francisco Bay
All current-meter data collected from 1981 to 1983 were from
stations in South San Francisco Bay (South Bay) (fig. 1). South
Bay has a surface area of approximately 554 sq km and a mean
depth of 3.4 m referenced to mean lower low water (MLLW). South
Bay is characterized by a deep basin in the northern 1/3 of the
embayment, a deep main channel (>10 m), and an expansive shoal to
the east of the channel for the remainder of the Bay (fig. 2).
Water properties vary seasonally and are controlled in part
by water exchange with the northern reach (Suisun and San Pablo
Bays) and seasonal meteorological variations within the region.
There are no major tributaries in South Bay and the area receives
3more than 75 percent (1.3 km /yr) of the total waste water dis
charged into the Bay system. During summer months sewage inflows
exceed natural stream inflows. Salinity of South Bay is nearly
isohaline and the typical salinity range is 25 to 30°/oo. How
ever, significant stratification may exist in winter and early
spring when maximum flows of freshwater enter South Bay via the
Delta and northern reach. Meteorological conditions for the
South Bay region are characterized by prevailing westerly or
northwesterly winds in the late spring, summer, and early fall
with more variable winds in winter (Gartner and Cheng, 1983).
Measurements of tidal currents
Tidal currents in San Francisco Bay consist of the sum of
numerous partial tidal constituents. Of these, half *a dozen
semidiurnal and diurnal partial tides and one overtide or harmon
ic are the most important. Because the frequencies of the
partial tides are different, resulting tides in San Francisco Bay
vary constantly as the partial tides move in phase (reinforcing
each other) and out of phase (canceling each other) in a fort
nightly cycle. The net effect of these phase differences gives
rise to the spring and neap variations of tides and tidal cur
rents. Long term variations also occur because long time
variations in the motions of the moon and earth relative to the
sun cause long term variations in the tide producing forces. One
of the principal objectives of the present field program is to
measure the tidal currents and define the partial tides from
these data. Clearly, the longer the time-series of field data,
the better each frequency can be separated and the more accu
rately each partial tide can be computed. Therefore, only
self-recording current meters which are capable of recording
tidal- currents for a minimum of 15 days were used.
Equipment

recording current meters. The Endeco-174 is an axial-flow,
ducted-impeller current meter which records data on a magnetic
tape cartridge. Data can be recorded for up to about 40 days
when the data-recording interval is selected to be 2 minutes.
Accuracy specifications for Endeco-174 current meters provided by
the manufacturer (Endeco Inc., Marion, Mass.) (Endeco 1978) are
as follows: speed,-3.0 percent of full scale (223 cm/s) above
the threshold (2.6 cm/s); direction, -7.2 ; temperature, -0.2 C;
and conductivity, -0.55 mS/cm.
Current speed is determined by measuring the displacement of
an encoder-disc driven by an impeller through a magnetic coupler
and a 500:1 reduction gear. Current direction (current meter
heading) is determined from the output of a damped magnetic com-i
pass. Temperature is determined by a thermilinear thermistor and
conductivity by an induction type electrodeless-conductivity
probe. Current speed is the average speed over the sampling
interval (2 minutes) while current direction and water tempera
ture and conductivity are instantaneous values at the time of
sampling.
Current-meter stations
Seven (7) current meter stations were deployed in the South
Bay region by the U.S. Geological Survey during 1981 to 1-983. A
total of 42 current-meter records were collected; equipment were
redeployed at the same location and multiple current meters were
deployed at several stations. The minimum length of current-
meter deployment was 14 days, and the maximum deployment was 43
days with the average deployment about 33 days. Figure 2 shows
the approximate geographic location of the current-meter sta
tions. The precise latitude and longitude and the water, depth
for each current-meter station at MLLW are compiled in table 1.
The positions of current-meter stations were determined by hori
zontal sextant fixes determined to the nearest second of arc (-31
m). Additionally, the sextant readings were routinely backed up
with radar and visual fixes. The latitude and longitude of each
station location were determined from published navigation
charts. Also included in table 1 are the depths at which the
current meters were deployed, and the deployment and recovery
dates for all data included in this report. All reference times
have been converted to Pacific Standard Time and Julian date.
Figure 3 is a chronological bargraph which indicates the period
of time during which current-meter data were collected during
1981 to 1983. The solid bars on the bargraph indicate current-
meter stations where multiple current meters were used for the
indicated period of time. Table 1, figure 2, and figure 3 define
the complete spatial and temporal distributions of the current-
meter data.

DATA PROCESSING PROCEDURES
Data translation
The raw data tapes from Endeco-174 current meters were read
and translated into computer readable codes utilizing a special
tape reader (Cheng and Gartner, 1979). The 2-minute interval
data were examined for possible record gaps, and individual
sensor calibration constants were applied to convert the data to
engineering units. Salinity was not directly measured; it was
computed from temperature and conductivity values based upon the
modified Cox relationship (D. Pritchard, unpublished notes,
1978). All computer programs used in the processing of these
data have been documented in Cheng and Gartner (1980).
Current speeds and directions (2-minute interval) were
vector-averaged to produce a new time series of 30-minute avera
ged data. Similar time series of 30-minute averaged temperature
and salinity data were also computed and stored on standard 9-
track computer tapes. The time-series of 30-minute average data
were used as input for harmonic analyses and time-series plots.
Time-series plot
A time-series plot of data is one of the most useful ways
for displaying current-meter data in a clear and concise manner.
Time-series plots of all data records are given in the Appendix.
The tidal-current velocity is plotted in the form of speed and
12
direction (relative to true north) versus time. Time-series
plots are used to provide a visual display of temporal variations
of tidal currents and their associated properties. Current speed
and direction data were not edited. Portions of the data may be
invalid due to marine fouling, malfunction of instrument, or for
other unknown reasons. Data compiled here are close to their
original form. Where questionable or unreliable data are appar
ent on the time-series plots in the Appendix, those sections are
noted. Only valid data (our own best judgement) were used in the
harmonic analyses. Whereas the time-series plots cover the
entire deployment, in the case of harmonic analysis the start
time and the length of the record analyzed are noted on the har
monic analysis summary sheets.
A time-series plot of water temperature and salinity versus
time is also given for each data file. If temperature data were
in error due to an electronic problem in an instrument, conduc
tivity rather than salinity was plotted because salinity could
not be computed without temperature data.
Accuracy of conductivity data may be affected by two condi
tions. These are the amounts of marine growth on the external
sensor and the battery voltage which is a function of the deploy
ment duration and water temperature. As a check on data
validity, conductivity (salinity) records were compared with data
from nearby water-sampling stations collected during research
cruises. If data were correct for only part of a deployment, the
plot was terminated at the time when the data were in agreement
with the last cruise sample or at the point of obvious electronic
failure- Additionally, spurious temperature and conductivity
13
readings in the records were corrected when identified.
The plotted data provide users with a visual record to exam
ine. For future reference and for special applications, all data
in 2-minute files and 30-minute files are currently stored on
computer retrievable media.
Harmonic analysis
The method of harmonic analysis for tidal current data is
well documented in Schureman (1940) and Cheng and Gartner (1984).
In all cases the data sets are truncated to an even number of M_
cycles (56 cycles maximum). The M2 cycle (12.42 hours) is used
for this purpose because it is by far the most dominant tidal
constituent (partial tide) in San Francisco Bay. The angular
frequencies of the tidal constituents included in the analysis
are given in table 2 .
Six harmonic constituents (0., K., N«, M 2 , S 2 , M.) were com
puted for east-west and north-south tidal velocity components.
Results of harmonic analysis of current-meter records collected
during the study are included in the Appendix. The tidal consti
tuents determined may be used for prediction of tidal currents at
the same location (Cheng and Gartner, 1984). In addition to per
tinent notes concerning the current-meter deployment and recovery
and the harmonic constituents, the summary sheets include some
general properties of tidal currents computed by the harmonic
Analysis program such as the root-mean-squared (RMS) current
speed, spring and neap tidal current maxima, principal tidal cur
rent direction, tidal current form number, and Eulerian residual

Depending upon the usable length of the record, the time average
velocities are computed for every 12 M« tidal cycles, and an even
number less than 12 M« cycles for the remaining available data in
the record. The time average for the entire record length (maxi
mum even M~ cycles) is also given.

SUMMARY AND CONCLUSIONS
Tidal current in South San Francisco Bay
At all stations, the tidal currents show a strong
bi-directional tendency. The principal current direction depends
strongly on the local basin bathymetry. There is a spring and
neap variation of the tidal current speed up to a factor of about
two. Form numbers less than 0.25 indicate a semidiurnal tide
while form numbers greater than 3.0 indicate a diurnal tide.
Form numbers between 0.25 and 3.0 indicate a mixed tide. As the
form numbers (0.13 to 0.52) indicate, the tidal currents in South
Bay are mixed semidiurnal and diurnal types; however, for most of
the cases the tidal current type is closer to semidiurnal than
diurnal.
The most important properties of tidal current in South Bay
can be characterized by five parameters: (1) the amplitude of M,,
tidal current ellipse (magnitude of semi-major axis of the M«
tidal current ellipse), (2) the RMS tidal current speed, (3) and
(4) spring and neap tidal current speed limits, and (5) the prin
cipal tidal current direction. The spatial distribution of these
parameters is plotted on a map of the South Bay region (fig. 4)
in which the M« , RMS, and the estimated spring and neap tidal
current vectors are plotted in the principal tidal current direc
tion at each station. The spatial distribution of the tidal
current suggests that the tidal current is strongly dependent on
the basin bathymetry.

Eulerian residual current in South San Francisco Bay
The Eulerian residual current is defined as the vectorial
average of the current-meter data made over several (even) M^
tidal cycles. This serves to average out the tidal signal; what
remains is the Eulerian residual. The Eulerian residual current
is generally a factor of ten smaller than the tidal current. As
the speed accuracy of the current meter is about 7 cm/s and the
current-meter record represents speed only at a single point in
the water column (and the water depth varies over a tidal cycle),
one must be careful in drawing conclusions from the Eulerian
residual currents. The computed Eulerian residual currents are
given in the summary for each current-meter data file in the
format of north/south (north - +) and east/west (east - 4-) compo
nents. The factors that affect the Eulerian residual currents in
South Bay are rather complex. Basin bathymetry, Delta outflow,
spatial distribution of tidal currents (tidal current shear),
long term temporal variations of tidal currents (spring and neap
variations), and wind forcing at the water surface are all impor
tant factors which may have effects on the magnitude and spatial
distribution of the Eulerian residual currents (see Walters,
1982; Walters and Gartner, 1985; and Cheng and Gartner, 1985).
Since the Delta outflow is one of the variables which affect the
Eulerian residual current in South Bay, the averaged values of
the Delta outflow during the current-meter deployments have been
computed from Dayflow summary (California Department of Water
Resources, 1984) and are given in the summary sheets.
19
The Eulerian residual currents (Appendix A and figure 5) are
in general agreement with expected values for winter conditions
(low and variable winds) in South Bay (see Cheng and Gartner,
1985). The Eulerian residual current vectors displayed in figure
5 are from current-meter records collected primarily in February
1981 and 1982. Stations GS-30 and GS-31 display vectors from
records collected from mid March to mid April 1983; the earliest
records available from those stations but still representative of
winter conditions. All records used in figure 5 are from current
meters deployed between 45 percent and 67 percent of the total
water depth (relative to MLLW). The vectors indicate the presence
of a clockwise gyre in the central part of South Bay and a coun
terclockwise gyre in the southern part of South Bay in the
winter.

APPENDIX
The current-meter data are presented chronologically and
station-by-station in Appendix A. For each file, the measured
data and the results of analyses are presented in two forms: (1)
results from the harmonic analyses; and (2) time series plots of
tidal - current velocity (speed and direction) versus time, and
salinity and temperature versus time. These results are given in
the order of station numbers as listed in table 1.
The following abbreviations are used in the appendix:
MLLW Mean lower low water (a tidal reference datum).
PST Pacific standard time.
CM/S Centimeters per second
DEC T Degrees true (angular measurement from true north).
RMS Root mean square.
CMS Cubic meters per second
