Shayla
Williams moved into a new world when she began work at the NEFSC’s
James J. Howard Laboratory in the fall of 2001. The move to New
Jersey brought the Florida
A&M
University doctoral student from the South to the North,
from the campus to the work-day world, and from a university
Environmental Sciences Institute to the NEFSC’s Ecosystems
Processes Division (EPD).
The transitions were a challenge
for the young Albany (Georgia) scientist, but with the help of veteran
research chemist Dr. Ashok Deshpande, Williams settled in to the EPD’s Marine
Chemistry Branch and began working on a study of bluefish and
environmental contaminants.Four-and-one-half
years later, Williams has finished her dissertation, received her doctorate
in Environmental Sciences, and officially converted from a student
employee to full-time NEFSC employee, stationed in Sandy Hook.
Williams
made the journey from student to employee in NOAA’s Graduate
Sciences Program, an effort to recruit and train outstanding
minority students with an interest in NOAA-related sciences. Her
stint as a student employee at the Sandy Hook laboratory was funded
by NOAA’s
Educational Partnership Program (EPP), and authorized under another
federal initiative called the Student
Career Experience Program (SCEP). Together the EPP and
the SCEP provide students with paid work-study experiences, giving
them a jump-start in their careers and a direct path to permanent
employment with the government agency that helps train them.
Williams
came to Sandy Hook after completing her Ph.D. coursework at Florida
A&M, a university that partners with NOAA in EPPs. In her early
days as an EPP/SCEP student, Williams encountered some of the baffling
bureaucratic intricacies that can crop up when large institutions collaborate
on multidisciplinary research programs.“I
was looking for funding,” she remembered, citing one example
of the difficulty of dealing with multiple administrative entities. “There
were federal grants I couldn’t apply for because I was a student,
and student grants I couldn’t apply for because I was a federal
employee.”
“The
EPP was new when Shayla came to Sandy Hook,” explained Dr. Ambrose
Jearld, the NEFSC Director of Academic Programs. The various partners
in the program – Florida A&M, the NEFSC, the EPP – had
not established clear lines of responsibility.
At
the time, Deshpande was acting chief of the Marine Chemistry
Branch, the group that was hosting the NEFSC’s first EPP/SCEP
student. “Ashok
really took the bull by the horns,” Jearld said. “He talked
to all the right people and got all the bureaucratic details ironed
out.”

Deshpande said the funding issues
were sorted out when Jacqueline J. Rousseau, the NOAA EPP director,
explained that EPP funding was available to support field work by SCEP
student employees.
In addition
to providing bureaucratic support, Deshpande provided research advice,
helping Williams design a project that would provide data for a doctoral
dissertation. The SCEP scientist ended up working with bluefish in
the Hudson River estuary, a project that contributed to the Howard
Laboratory’s long-running study of environmental contaminants.Bluefish
spawn offshore in the late spring and summer. The larvae develop into
juveniles in continental shelf waters. In June, the juveniles begin
arriving in coastal nurseries. Voracious predators, the young bluefish
spend the warm months in estuaries, feeding on a variety of fish and
invertebrates, and growing as much as 2.2 millimeters per day. When
the waters turn chilly in October and November, the fish leave the
estuaries to migrate southward.
Many
East Coast estuaries are contaminated with PCBs – human-made
chemicals that were used in industrial and commercial processes before
they were banned in 1977. Bluefish that spend their summers feeding
in the estuaries ingest PCBs and accumulate them in their fatty tissue.
They also accumulate inorganic metallic chemicals in their otoliths
(small bones in their ears). Deshpande and other Sandy Hook scientists
are exploring the idea that bluefish feeding in different estuaries
will have different PCB signatures in their fatty tissues and differences
in their otoliths that can serve as chemical fingerprints that reveal
where individual fish have spent their summer.
Williams
spent three years catching bluefish in different locations in
the Hudson River estuary. When she analyzed their fatty tissues and
otoliths, she found evidence that the fish do not migrate extensively
within the estuary. She also found that the chemical profiles of Hudson
River bluefish are distinguishable from profiles of bluefish in other,
nearby estuaries. Her results may help fisheries scientists understand
bluefish populations and may be useful in answering questions about
which estuaries are important for bluefish stocks.
In
2004, with three years of data in hand, Williams faced another
culture shock – the transition from data-gatherer to dissertation-writer.
Fortunately, the young scientist was not unfamiliar with the
world of writing – her father was an English professor (now retired)
at Albany ( Georgia) State University.“Two
years ago I was sitting in front of a blank screen,” Williams
said, recalling a process that involved seemingly endless rounds
of writing, rewriting, getting reviews, and making corrections. “I
had one sentence when I started,” she said, “and
now I have a 200 page document.”
Churning
out that document was the next to last step in Williams’ journey
to her Ph.D. The final step came March 20 when she defended
her dissertation, “Bioaccumulation
patterns of organochlorines in young-of-the-year bluefish
(Pomatomus
saltatrix) in the Hudson River Estuary."
“Defending
it was the easy part,” she said. “I knew I could defend
it. I had confidence in the data.”
With
Williams’ dissertation complete and her Ph.D. in hand, the NEFSC
has its first EPP SCEP program success story – a well-trained
scientist capable of stepping right in to the Center’s research
program. Deshpande and Williams are already collaborating on two papers,
with Williams serving as first author on one.According
to Deshpande, the NEFSC’s first SCEP alumnus is a serious and
dedicated young scientist who has earned the respect of her colleagues
in the EPD.
“Shayla
learned many aspects of science while she was in the program,” Deshpande
said. “She has experience collecting samples, analyzing data,
interpreting data, and doing statistical analysis.”
Williams
agrees that the EPP SCEP program is a winner. “I’d
recommend it,” she
said. “It is a way to get you into the system, and to help you
make the transition from being a student to being a federal employee.”
