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

Current meters used in the study are Endeco-174 digital

Survey.

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
