THE STATE OF TEXAS j Texas Water Development Board
and
COUNTY OF NUECES j , City of Corpus Christi
This Contract and Agreement, made and entered into by and between
the Texas Water Development Board, hereinafter called the Board, and the
City of Corpus Christi, . hereinafter called Cooperator, in a Cooperative
Estuarine Investigation Program under the following terms, conditions and
considerations, WITNESSETH:
ARTICLE I
1. The Board, at the request of the Cooperator, and for the
consideration hereinafter expressed, agrees and covenants to cause to be
extended gLnd continued for an additional period of one year. beginning
September 1, 1973, the program of Estuarine Investigations described and
initiated in that certain contract dated September 1, 1972, between the Board
and the Cooperator, being Texas Water Development Board Contract No.
03 -3737, to which contract reference is here made. The said program is a
cooperative effort by federal and state agencies, and is described as follows:
A. The Board has an estuarine data - collection program currently
underway in cooperation with the U. S. Geological Survey.
Under this program, field and laboratory data - collection is
performed by U. S. Geological Survey staff and Board staff
using watercraft and equipment of the Geological Survey.
Repetitive surveys are to be taken in the Corpus Christi and
Aransas- Copano Bay systems including collection of field
data (dissolved oxygen, temperature, conductivity, pH) and
samples for laboratory analyses of a wide range of organic
and inorganic water quality parameters at carefully selected
sites throughout the estuarine systems.
r
B. The Board is presently involved in the development and
verification of mathematical hydrodynamic and transport
(salinity) models of the Corpus Christi and Aransas - Copano
Bay systems, .Intensive inflow - exchange -water quality
studies involving simultaneous measurement of current
velocities, net exchange through tidal passes, river and
tributary inflows, meteorological data - collection, and
channel profile surveys have been conducted to provide data
for accurate verification of these models. ' When fully
verified the models will simulate the distribution of salinity
and the variations in the hydraulic behavior of the bays
•
under any prescribed hydrologic and meteorologic condition.
2. The said program of estuarine investigations is more particularly
described in, and shall be carried out in strict accordance with, Attachment A,
entitled:
CORPUS CHRISTI BAY -- BENTHOS AND PLANKTON STUDY
Ecological Studies of Corpus Christi Bay and Contiguous Waters
• Including Evaluation of Estuarine Productivity and Nutrient
Budgets Under Varying Seasonal Conditions
The said Attachment A is appended hereto and made a part of this contract
for all purposes.
3. Funding of these cooperative studies and programs will provide
for an expansion of the biological data - collection, which is considered essential
to fully describe and understand the total estuarine ecosystem -- including
the complex food chain. The complex ecological interactions must be fully
understood in order to develop meaningful correlations between fresh water
(including nutrients) and Gulf water inflows to the estuaries.
4. Supplementary funds provided for in Article III of this contract
by the Cooperator will be used to expand staff to conduct an expanded program
of ecological studies. An estimated expense summary for the program for
the 1973 -1974 fiscal year is given in Attachment A. Specifically, investigations
-2-
and surveys will be initiated to define existing standing crops of phytoplankton,
zooplankton, and benthic organism's and seasonal variations in abundance
and species of such organisms - -as influenced by varying physical, water
quality, and related environmental conditions in the estuaries. Chemical,
physical and biological data will be collected at representative stations
within the Corpus Christi Bay system at monthly. intervals. All data will
be analyzed to determine ecological changes in the estuary resulting from
variations in inflow into the estuarine systems.
ARTICLE II
The expanded program is estimated to cost Fifty -Five Thousand
Five Hundred Eighty -Nine and 84 /100 ($55, 589. 84) Dollars. Cooperator,
in consideration of the foregoing agreement and undertaking on the part of
the Board, hereby covenants and agrees to pay to the Board the sum of Thirty
Thousand ($30, 000.00) Dollars on demand after the date of execution of this
agreement as its share of the said estimated cost of the program.
ARTICLE III
The parties hereto agree that this Contract is subject to the availa-
bility of funds to the Board, provided, however, that should such funds be
not available, this Contract shall be null and void, and funds contributed by
the Cooperator shall be refunded in full.
ARTICLE IV
It is mutually agreed and covenanted that if the Cooperator shall
fail to make payment as herein provided, the Board may cancel and
terminate the remainder to this Contract by giving Cooperator written
notice. If this Contract is terminated prior to the time of full performance,
the Cooperator shall be obligated to'pay the Board for work already performed
hereunder, or as appropriate, the Board shall refund all that portion of
Cooperator's contribution which has not already been expended, or which the
Board is not obligated to expend on work that has already been performed
-3-
hereunder up to the date of cancellation and termination.
ARTICLE V
The parties hereto,further agree that this Contract may be altered
or amended upon the advance written agreement of each party to exclude.
work being performed or to include additional work to be, performed and to
adjust the consideration to be paid hereunder by virtue of such alterations
or amendments.

-- ATTACHMENT A •
CORPUS CHRISTI BAY -- BENTHOS AND PLANKTON STUDY
Ecological Studies of Corpus Christi Bay and Contiguous Waters
Including Evaluation of Estuarine Productivity and Nutrient
Budgets Under Varying Seasonal Conditions
I. Introduction
Investigators at the University of Texas Marine Science Institute
are presently engaged in a study of the benthic and planktonic communities
in the Corpus Christi Bay complex. All principals involved in the design
and funding of the present research agreed that a minimum of three years
would be necessary to investigate the complex variations of benthic and
planktonic populations in Corpus Christi Bay. The first year of research
is nearing completion.
II. Objectives
The objectives of the second year of this study will continue to be
the same as in the original proposal. They are:
1) A survey of benthic and planktonic communities and their sea-
sonal fluctuation in the Corpus Christi Bay complex;
2) Definition of the nutrient budget of the estuarine system, using
data collected under the existing Texas Water Development Board -- United
States Geological Survey cooperative estuarine program, and supplemented
as necessary with field and laboratory data developed by the Project Director;
3) Definition of the primary biological productivity of the Corpus
Christi Bay system for the project period, and
4) Correlation of the nutrient supply and primary productivity of
the estuarine system with fresh water inflows.

III. Proposed Research
The investigation will continue using the same .techniques and sam-
pling sites. (See Appendix A for present methods.) Benthos and plankton
samples are being collected from 30 stations in the Corpus Christi Bay com-
plex. Analysis of the first year's data may indicate that some of the present
stations are not providing useful data, if so they will be dropped, but no less
than 25 stations will be sampled monthly, as per the original proposal.
The project will continue to be administered by the T. W. D. B. and
be coordinated with the existing US.G.S. - -T. W. D. B. cooperative estuarine
program and the Texas Parks and Wildlife Department biological sampling
program. Chemical, physical and biological parameters will be collected
on a coordinated basis.
Results of the project will provide data essential for the ultimate
development of management programs for the estuarine system, particularly
as these relate to the quality and quantity of fresh water„ and nutrient inflows
required.
Monthly progress statements and quarterly reports concerning
research status will be made to the T. W. D. B. Twenty -five copies of a final
report of all research and results of the project will be submitted to The
Board at the completion of the project. The report shall include all basic
data derived from the project.
The proposed research will begin on September 1, 1973 and ter-
minate August 31, 1974. Additional research, at least a third year, will be
necessary to adequately define the benthic and planktonic community seasonal
progression.

IV. Explanation of Expenses
Expendable equipment and supplies -- Expendable equipment and
supplies will include those required to collect, preserve, store and analyze
_ benthos and phytoplankton samples.
Boat time, travel and publication costs- -Boat expense is based on
use of The University of Texas research boat, the SHORTHORN, a 19 ft. out-
board, for 4 days (at $50 per day) each month over, a 12 month period. Travel
money is included to cover expenses of research personnel: as trips for con-
sultation with the T. W. D. B. personnel or others and for library research
have proven necessary. Publication costs will cover the expense of produc-
ing and printing the final report.
Salaries - -As outlined, salaries of personnel involved in this proj -.
ect are at or near the University of Texas minimums for the positions. The
increase in salaries this year reflects University of Texas salary increases,
an increase in the Project Coordinator's time spent on the project, and an
increase in number of project personnel. The Principal Investigator is not
asking for remuneration for his time on this project. The work load for the
past year has indicated that the requested number of personnel is necessary
to perform the research competently.

Appendix A
Field and Laboratory Techniques
I. Benthos
Field -- Bottom samples (a ft3) are collected with a Petersen grab
and placed in 6 -gallon plastic containers. Formalin (37 %) is stirred into the
samples to approximate a 57o mixture.
The samples are carried back to the outdoor lab where they are
washed with a gentle stream of fresh water, using a washing table which has
a screen with mesh of a inch openings and a bag with mesh of 1/32 inch open-
ings. Larger specimens are picked off the screen and placed in small con-
tainers with 70 % ethanol (or isopropanol). Rocks and shells which have
serpulid worm tubes or barnacles are placed in a bucket also containing 7016
alcohol. Whatever remains in the mesh bag (specimens, dead shell. debris)
is placed in buckets (1 to many, depending on the amount present) and mixed
with 70% alcohol. All buckets and containers are labeled with station number
and date of collection.
Laboratory - -The sample buckets containing "serpulid rocks" are
checked in their entirety for barnacles or worms or other organisms clinging
to them. Oysters are counted. A partial sample is then weighed and the
serpulid tubes checked for polychaetes. The weight of the total sample is
also determined, so that we are subsampling by weight for serpulids.
The buckets containing the contents of the mesh bag are "swirled"
to separate organisms from dead shell. A handful or so of the shell is placed
in a bucket, water added, and then swirled around rapidly. After allowing a
second or so for the heavier shell to settle, the water is poured off through
screens of 10, 20 and 40 mesh size. This procedure is repeated until the
water pouring off is clear. The residue is checked under a magnifying lamp
for anything that may have remained behind. We find that one or two species
of bivalves and one species of gastropod usually do not swirl out, but all
other varieties of organisms do.
Each screen is washed off and checked, and the "swirlings" are
inspected under a dissecting scope. Th a organisms are sorted to species.
Each species is named and counted. and if it is to be kept, placed in a vial of
7016 alcohol. We usually use 1 dram vials with plastic pop -tops, but larger
specimens are placed in appropriately larger vials. Each vial is labeled with
station number, date of collection and name (genus and species) of the organism
(written on a slip of paper inside the vial). and each vial is sealed with hot par-
affin wax to prevent possible evaporation of the alcohol.
A list is kept for each station, each collection showing genus and
species and numbers of organisms collected.
II. Zooplankton
Field -- Zooplankton samples are collected by towing a a meter diam-
eter conical net constructed of #10 nylon netting (150,u openings) for one minute.
The net is allowed to settle some in the water column before the towbegins,
and is pulled to the surface by the end of the tow. so that an oblique tow has
been made. The amount of water filtered is measured by a General Oceanics
Model 2030 digital flowmeter attached to the mouth of the net.
The net is washed down aboard the boat, in order to concentrate
the sample in a plankton bucket. Ctenophores are retained on a screen and
either counted individually or poured into a graduated cylinder and measured
by volume. The sample in the plankton bucket is washed with sea water into
a 32 oz. jar and 100 ml of a 50/6 buffered formalin solution added as a preserva-
tive.
Laboratory- -The sample is diluted to a measured volume and a 1 ml,
2 ml, 5 ml or 10 ml aliquot (depending on the density of the zooplankton) is
taken with a Hensen - Stemple pipette. This subsample is inspected under 25x.
The entire sample is then checked under 12x to identify and count organisms
not found in the subsample. Organisms are identified to genus and species
where possible and counts are reported in individuals per cubic meter.
III. Phytoplankton
A one liter sample of surface water is collected and fixed with 100 ml
of 5% buffered formalin solution.
Of this liter, 500 ml is concentrated to 35 -50 ml (depending upon the
density of phytoplankton) through a Sedgwick- Rafter concentrating apparatus.
A 1 ml sample of this concentrate is placed on a Sedgwick - Rafter counting cell.
Species are named and individuals counted. The final result reported in cells
per liter. A Nikon microscope is used for identification work.
IV. Water Quality Measures
Currently we are measuring water depth, dissolved oxygen, conduc-
tivity and temperature. Readings are made at one foot below the surface,
at mid = depth, and one foot above the bottom.
Conductivity is measured with's Martek Model TDC,(Martek Instru-
ments, Inc. ). Specific conductance is measured in MMHO /CM.
Oxygen is measured on a YSI Model 54 oxygen meter (Yellow Springs
Instrument Co.). The meter readings are converted to mg /1.
