TWDB Contract No. 03 -5301
THE STATE OF TEXAS Texas Water Development Board
and
COUNTY OF NUECES 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 and continued for an additional period of one year beginning
September 1, 1974, 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.
0 " ". .... 0
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
(Fiscal Year 1975)
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 1974 -1975 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 organisms 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 Sixty -Five Thousand
One Hundred Seventy -One and 46/100_ ($65, 171. 46) 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

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.
IN WITNESS WHEREOF, the parties have caused this Contract and
Agreement to be duly executed in triplicate, this the 1st day of September, 1974.

Attachment A
CORPUS CHRISTI BAY -- BENTHOS AND PLANKTON STUDY_
(Fiscal Year 1975)
Ecological Studies of Corpus Christi Bay and Contiguous
Raters 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. This proposed contract will
conclude the three year investigation.
II. Objectives
The objectives of the third 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 seasonal 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 sampling sites. (See Appendix A for present methods.)
Benthos and plankton samples are being collected from 30 stations
in the Corpus Christi Bay complex. Zooplankton sampling will
be decreased to approximately 20 stations. This change is
indicated by overlapping data and the relatively long period
required for the laboratory analysis of zooplankton samples.
The project will continue to be administered by the
T.W.D.B. and be coordinated with the existing U.S.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
y .-
system, particularly as these relate to the quality and quantity
of fresh water and nutrient inflows required.
Monthly progress statements and quarterly reports con-
cerning 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 proposed research will begin on September 1, 1974
and terminate August 31, 1975. Collections will be made through
'may, 1975. The last three months of the project will be reserved
for data analysis and report writing. The final report will.in-
clude a summary of the entire three year project.

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
SEORTHOILV, a 19 ft. outboard, 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 consultation with
the T.W.D.B. personnel or others and for library research have
proven necessar�. Publication costs will cover the expense of
producing and printing the final report.
Salaries --As outlined, salaries of personnel involved
in this project are at or near the University of Texas minimums
for the positions. 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 (370) is stirred into the samples to approximate a
5% 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 4 inch openings.
and a bag with mesh of 1/32 inch openings. Larger specimens
are picked off the screen and placed in small containers with
700 ethanol (or isopropanol). Rocks and shells which have
serpulid worm tubes or barnacles are placed in a bucket also
containing 70% alcohol. whatever remains in the mesh bag (spec-
imens, 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 poly -
chaetes. The weight of the total sample is also determined,
so thav,w- 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 ?or the
�eavier 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'. '
Eachiscreen is washed off and checked, and the "swirlings"
are inspected under a dissecting scope. The organisms are
sorted to species. Each species is named and counted, and if
it is to be kept, placed in a vial of 70% alcohol. We usually
use 1 dram vials with plastic pop -tops, but larger specimens
are placed iri 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 paraffin 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 -
�; peter diameter conical net constructed of #10 nylon'netting
(150u openings) for one minute. The net is allowed to settle
some in the water column before the tow begins, 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 flowmeier -attached too 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.
ja'r and 100 ml of a 5% buffered formalin solution added as a
preservative
•
Laboratory- -The sample is diluted to a measured volume
and a 1, 2 ,5, or 10 ml aliquot (depending on the density of the
zooplankton) is taken with a Hensen - Stemple pipette. This sub -
sample 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, conductivity and temperature at one foot below the
surface, mid - depth, and one foot above the bottom.
Conductivity is measured with a Martek Model TDC (Martek
Instruments, Inc.). Specific conductance is measured in MMH0 /CIJ.
Oxygen is measured on a YSI Model 54 oxygen meter
(Yellow Springs Instrument Co.). The meter readings are converted
to mg /1•
Turbidity end pH are measured at the surface. Turbidity
is measured on a` Hach Chemical Co. Direct.Reading Engineer's
Laboratory in Jackson turbidity units.
pH is measured on a Sargent -Welch Model PBL pH meter. '
