RESEARCH
INTERESTS
My
major research interests include marine phytoplankton
ecology, physiology, bio-optics, biochemistry,
primary production and taxonomy with particular
emphasis on the effects of environmental factors
on carbon and nitrogen metabolism, cellular
composition and growth at the species and population
levels of both laboratory cultures and natural
populations.
Additional areas of interest include the biogeochemical
cycling of organic materials in the upper layers
of the ocean, in both coastal and oceanic environments
and the effects of various dissolved and/or
suspended components on the light absorption
characteristics of marine phytoplankton.
Another area of research interest is the mass
culture of marine and freshwater microalgae
for the production of various commercially important
materials including plant pigments and compounds
with anti-cancer activity. Mass culture of microalgae
may also be helpful as a means to reduce atmospheric
CO2 and my research examines aspects of how
this might be accomplished.
New areas of interest for me are that of Marine
Science and Public Policy and of Integrated
Coastal Mangement. This effort includes examination
of coastal resources, scientific information
and public needs as they each contribute to
coastal resource management.
This is the core course in biological oceanography
and laboratory required of all Department of
Marine Science students. In this course we examine
the important biological components of marine
systems, the processes which impact marine ecosystems,
the biogeochemical cycling of biologically important
elements and materials, and many of the approaches
taken by oceanographers to study the ocean.
We focus on the physical and chemical environments,
microbial communities, phytoplankton, zooplankton,
nekton, and the shallow and deep benthos. This
course is taught every year in the Spring semester.
Science and politics often come together in
complicated and interesting ways. In this course
we will examine how oceanographers and other
marine scientists communicate with those who
are responsible for formulating public policy.
What information should the scientist provide
the policy makers so that informed policies
can be developed? In what form should these
scientific findings be provided so that policy
makers will take home the intended message?
We will examine these and other related questions
following the concepts generally referred to
as “Integrated Coastal and Ocean Management.”
In addition, students will be expected to choose
a marine policy topic (topics may come from
the subject areas covered in the lectures, in
papers in the marine policy and management literature,
or you may, with approval from me, choose another
policy related topic) and prepare a term paper
on the chosen topic. Each student will prepare
an oral presentation of their term paper and
present it to the class; the presenter will
then lead a class discussion on the material
presented. This course is taught in alternate
years in the Fall Semester.
• Fisheries Oceanography (MAR 603)
In the past, there has been a profound gap between
oceanographers who are concerned with gas or
nutrient exchange processes, or the spatial
dynamics and processes of water bodies and plankton,
and fisheries scientists who are more concerned
with biology of fishes, population dynamics,
and recruitment or predator-prey relationships.
Fisheries oceanography combines elements of
both oceanography and fisheries approaches to
the understanding of this dynamic and multidisciplinary
field of science.
The objective of this course is to provide students
with a basic understanding of fisheries oceanography
and its multidisciplinary nature so that students
can begin to appreciate the need for a holistic
approach to addressing these complex sets of
issues. We will accomplish this through a combination
of lectures that will examine various elements
of fisheries oceanography followed by the discussion
of a series of case studies where both fisheries
and oceanographic information was necessary
to explain field and catch observations. Students
will then be asked to make an oral presentation
on some aspect of fisheries oceanography and
submit a written, research-based, term paper
upon which the oral presentation will be based.
This will be followed by a written take home
final examination to complete the course requirements.
This course is taught in alternate years in
the Fall Semester.
