Snapshot
WHOI Sea Grant's investment in environmental technologies has resulted
in the development of new tools for analyzing and interpreting the
effects of toxic chemicals on the reproduction, development, and
disease defenses in marine animals and for detecting the presence
of harmful algal species before bloom conditions occur.
Background
Coastal ecosystems in southeastern Massachusetts are subjected to
many of the same perturbations as other coastal ecosystems: increasing
pressure on coastal resources as coastal populations and development
increase, conflicts between private ownership of the coast and public
access, tourism, pollution, declining natural fisheries and exploration
of alternative fisheries, development of aquaculture, natural shoreline
change through storms, erosion, and coastal processes, and human-induced
coastal change.
Public awareness and concern for environmental problems
in coastal ecosystems are very high within local communities of
southeastern Massachusetts. Local concerns -- groundwater contamination
and sediment contamination in an urban harbor -- and the remediation
required to minimize ecological and human health threats, provide
a central focus for research and outreach in environmental technologies.
In response to these and a wide range of other environmental problems,
an Enviro-Tech Center has been located at the Massachusetts Military
Reservation. The Center fosters the development of innovative technologies
by the private sector and encourages partnerships with educators
and students to explore educational and economic opportunities associated
with environmental technologies. In addition, academic programs
are beginning to focus on training students for career opportunities
in environmental technologies at the secondary, undergraduate and
postgraduate levels. .
Objectives
WHOI Sea Grant's theme in Environmental Technologies is consistent
with the needs for better information and application of new technologies
and was developed as a way to respond to local and regional concerns
such as those highlighted above. Within the framework of the NOAA
Sea Grant Strategic Plan, 1995-2005, WHOI Sea Grant efforts are
focused on three major portfolios: Economic Leadership, Coastal
Ecosystem Health and Public Safety, and Education and Human Resources.
Within these portfolios there are major strategic initiatives in
advanced technology for commercial products, seafood production,
coastal economic development, coastal ecosystem processes, public
safety, technology transfer, and public outreach. To fulfill our
objectives and mandate within the strategic plan, WHOI Sea Grant's
theme in Environmental Technologies has focused on:
- Incorporation of the tools of molecular biology to better understand
and characterize the effects of toxic chemicals on reproduction,
development, and disease defense in marine animals;
- Development of new analytical tools and instrumentation for
monitoring water quality and sediment quality in coastal habitats;
- Identification of unique molecular or immunological properties
of individual plankton species that allow the development of species-specific
probes that can be used to characterize the distribution of these
organisms in natural habitats.
Sea Grant Involvement
Since 1990 the WHOI Sea Grant program has made an investment in
attracting and supporting activities in the field of marine biotechnology.
These efforts have focused on:
(1) the initiation of research projects that will
develop and deploy innovative technologies to address specific problems
in coastal ecosystems; and
(2) the development of advisory and outreach activities
to foster information transfer, education and development of new
monitoring and treatment technologies.
Program components include the application of molecular
biology to better understand contaminant effects in the environment
and ecological processes. In addition, predictive models have been
developed that integrate analytical approaches for identifying contaminant
distribution and effects in coastal environments with management
approaches for reducing the input and impact of contaminants in
the environment. These components compliment two portfolios within
the national strategic plan, economic leadership and coastal ecosystem
health and public safety, by integrating product development leading
to a better understanding and prediction of contaminant fate and
effects in coastal and estuarine environments.

Contributions to the Scientific Community
Research projects supported between 1990-2000 have yielded numerous
advances and discoveries within the scientific community. A few
highlights include:
- Investigators used cell culture instead of chemical analysis
to detect the presence of contaminants, based on a biomarker response.
These studies, conducted in the early 1990s, represented a novel
approach to contaminant assessment in coastal habitats.
- A study employing molecular biological techniques resulted
in the development of probes to identify organisms known to cause
harmful algal blooms (HABs).
- A gene library was the result of a Sea Grant project to look
at biochemical processes in marine organisms specificially directed
at identifying genes responsible for detoxification processes.
- A tissue library of cetacean samples for the study of chemical
sensitivity in marine protected species was developed by investigators
studying molecular biomarkers.
- Looking at aquatic bird populations, investigators showed that
exposure to contaminated feeding areas has no clear impact on
endocrine dysfunction, proving the complexities of cause-and-effect
relationships in nature in several degraded habitats. This project
also served as the basis of a Ph.D. thesis.
- If investigators are successful, a new tracer for identifying
bivalve larvae -- by looking at the trace metal composition of
larval shells -- will greatly enhance the ability of researchers
and resource managers to understand distribution of various populations
of bivalves.
