Scientists study mining impact
A group ofTAMU scientists are
scheduled to help conduct a marine
environmental impact study near
the Hawaiian islands.
The federally funded “Deep-
Ocean Mining Environmental
Study (DOMES)” is being done to
identify potential problems from
the mining of manganese nodules.
Dr. Sayed Z. El-Sayed and Dr. T.
Ichiye, of the Department of
Oceanography, and Dr. G. A. Fran-
ceschini, of the Department of
Meteorology, last week attended a
meeting in Seattle Wash, to discuss
cruise plans with other principal in
vestigators from the University of
Washington, University of Hawaii
and the National Oceanographic
and Atmospheric Administration.
Other TAMU investigators include
biochemist Dr. Nestor Bottino,
Hallmark Stationery & Notes, “Peanuts” Stationery, Gibson
Scrapbook & Photo Albums, Personal & Travel Diaries, Guest
Books & Bibles.

statistician Dr. C. E. Gates, and
oceanographer Dr. G. A. Fryxell.
Scheduled to leave Seattle Au
gust 21 aboard the NOAA research
vessel “Oceanographer”, the team
will conduct physical, chemical and
biological oceanographic studies
south and east of Hawaii.
“Probably much of the mining
will have to be done with a vacuum
dredge, which means a huge plume
of bottom material will be dumped
into the water column to settle out,”
El-Sayed said. ‘The main goal of the
project is to identify these environ
mental problems early enough to
produce a timely response to the
requirements of the National En
vironmental Policy Act.
“Now it is illegal for any country
to do anything to the ocean or ocean
floor without an environmental im
pact study,” he said.
“After the samples are taken, we
will study them and set up baseline
levels of marine life and contamina
tion,” he said. “Then next year,
March through December, we will
return to determine the effect of
discharge on the marine popula
tions at the mining sites.
“The funding for the first three
months for us is $75,000 with an
understanding that the additional
work will have substantially higher
funding, ” El-Sayed said.
The project will look at zoop
lankton, upper-water-column
chemical oceanography, and
upper-water-column physical
oceanography in order to evaluate
the magnitude that deep-ocean
mining might have on the marine
environment.
“After the mining operation is
started we will place more than half
the observation stations
downstream (due to the currents)
from the work site,” El-Sayed said.
“This would characterize the influ
ences of the deep-sea mining on the
phytoplankton. This material com
pared with the pre-mining studies
will show what damage, if any, that
has occurred as a result.

Twenty-five fish from TAMU
went into space last week as part of
the Apollo-Soyuz mission.
The month-old killifish, raised at
TAMU, may tell researchers about
the workings of the inner ear when
subjected to the zero gravity of
outer space.
Dr. Karl Kuchnow, TAMU
biologist and project director, said
that the fish were sent aloft in five
sealed containers aboard the Apollo
craft. Each container carried a
slightly different group of killifish.
Each group had been raised with a
different visual background.
Astronauts Thomas Stafford,
Vance Brand and Deke Slayton
spent part of their time filming and
recording how the fish adapted to
the weightless state.
Kuchnow said that on earth the
fish had two basic cues for orienting
themselves — sight and gravity.
With gravity no longer a factor, the
fish had to adapt themselves visual
ly-
The five containers held fish
raised with a normal background
since hatching, a second group with
no sight, one raised with horizontal
bars as a background, the fourth
with a vertical-bar background and
the last with a black background.
No quarantine was expected for
the containers after splashdown.
NASA officials were expected to
take them from the capsule within
seven hours of splashdown and have
PV researcher
pinpoints safe
cadmium level
PRAIRIE VIEW — A PVAMU
researcher has determined how
much cadmium can be contained in
sandy soil before harmful amounts
are transmitted through plants to
humans.
Dr. Gene Brams of PVAMU said
that two years’ soil study in the
Houston area has revealed that a
concentration of one part-per-
million (PPM) of cadmium in sandy
soil is the highest safe level.
One PPM, he said, is about equal
to two pounds of the metal concen
trated in an acre of soil plowed eight
inches deep.
“This level of one PPM causes the
level of cadmium taken in by plant
life to rise to a point that might be
harmful to humans consuming the
plant food, ” he said.
Chicken fried steak like
you wouldn’t believe.
The 3-C Corral serves a chicken fried steak like you
wouldn’t believe. We start with !4 pound of round
steak — without a speck of “extender.” We double dip
each steak in our own batter, fry it to a golden brown
and deliver it to your table hot and ready to eat. The
chicken fried plate also includes a generous serving of
french fries, fresh green salad and a roll.
And the price is about the same you’ve been paying
for a pre-breaded steak: $ 2 35
If you like chicken fried steak (and nearly every
Aggie does) you’ll find a home at the 3-C Corral.

Analyses of the astronauts’ films
and observations, as well as viewing
of the inner ears of the fish, were
scheduled to be done at TAMU.
Researchers from the University
of Kentucky were involved in
another Apollo fish experiment de
aling with effects of space on varying
stages of embryo growth.
