Strategic Goals
Playing a
Leading Role in Developing the Infrastructure Necessary for Integrated
Marine Processes Modeling and Measurement
- Acoustic
communication technology: MIT Sea Grant recognizes
considerable technical opportunity in the area of ocean acoustics
for communication and naviagation. Signal processing methods
that enable reliable communications in the presence of acoustic
channel distortion should focus on optimal exploitation of
limited communication resources (bandwidth and energy). Research
areas of interest include adaptive modulation/detection,
efficient coding, array processing, and interference suppression
in high-rate links and communication networks. Data compression
methods that address sonar, seismic, and video signals are
of interest. Maximal compression ratios, together with reliability
and power consumption trade-offs must be addressed in the
context of underwater sensing and imaging systems' requirements.
- Ease
of remote data processing, archiving and distribution: As
ocean and marine research becomes more synoptic and spatially
expansive, the ability to easily access and visualize data
and employ different modeling systems (such as those representing
physical, biological, chemical and acoustical ocean phenomena)
also becomes more important. This will assist in better oceanic
phenomena prediction and improved assessment of natural and
anthropogenic effects. Future research in this area includes
dynamic data driven simulations combined with dynamic adaptive
sampling methodologies and real-time data driven forecast
systems in a distributed computing environment.
- Distributed
networks and communication protocols: We encourage
research that improves access to and enables flexible use
of distributed instruments in coastal and deep ocean observatories.
Research areas of interest include fundamental networking
concepts that will provide the basis for optimal resource
allocation in the underwater environments, as well as design
of network protocols that specifically address application
to ocean observation systems.
Exploiting
Marine Animal Behavior and Ocean Phenomena
- Cetacean
sonar locating and communication: Much can be learned
from continued in-depth study of the sonar capabilities of
certain marine life. The ability to locate prey and other
creatures of the same species, as well as avoid obstacles
in less than ideal conditions via sonar locating and interpretation
is of great interest and application for ocean instrumentation
and system concepts.
- Biomimesis-Learning
from nature: During the last ten years we have supported
research in the application of biomimesis-a process by which
we design systems using principles employed by living organisms.
This research track benefited greatly from the design and
evaluation of scale models of fish noted for outstanding
speed (the tuna) and for great maneuverability (the pike).
New fluid mechanics mechanisms were discovered, governing
the sensing and control of unsteady flows to achieve very
high performance for marine craft. We are committed to studying
the engineering aspects of biomimetics because this program
will allow us to engineer AUV-type platforms with fish-like
attributes and will help us further understand basic issues
related to fisheries.
- Energy
from the natural marine environment: Existing renewable
sources of energy, such as windmills and solar power, provide
energy with minimal impact to the environment. Many marine
sources, such as current, tides and waves, can serve equally
well as useful energy sources. Future research in this area
includes studying the engineering aspects of extracting energy
from these marine energy sources, and supporting their application.
Supporting
the Development of Critical Technologies Needed by the Oocean
Research, Educational, and Commercial communities
- The
next generation of AUVs-enhancing capability through improved
dexterity and perception: Exploring and working
in the ocean remains a priority for the program. To fulfill
this ambition, our challenge begins with designing the next
generation of autonomous underwater vehicles. Such novel
AUV incarnations will include crafts capable of hovering,
vehicles that crawl and biomimetic creatures. Expanding the
capabilities of these robots requires developing complementary
sensing modalities and the required sensor technology, such
as chemical and optical sensors, to achieve new mission objectives.
- Navigation
and control theory and adaptive behavior: As the
range and mission duration of autonomous platforms increase,
the requirements of robust control and precise navigation
are paramount for successful deployments. We have encouraged
recent research efforts in new navigation algorithms that
incorporate feature-based learning for an AUV to meet this
challenge. Advanced modeling and control concepts are the
crux of developing theory that will lead to robots making
intelligent decisions on their own while operating in familiar
or unknown environments. This research strategy emphasizes
the need to further hone the applications of artificial intelligence
in underwater robotic systems.
- Turbulence
control: Understanding turbulence is one of the
great ongoing problems in classical physics and a continuing
grand challenge in hydrodynamics. Suppressing turbulence
is key to solving a number of important engineering problems
including frictional drag reduction in ships, elimination
of noise in submarines, enhancement of acoustic communication
between underwater vehicles, and efficient maneuvrability
of all types of vehicles. A particularly attractive approach
that takes advantage of the ocean water's electric conductivity
is the use of electromagnetic excitation. Preliminary simulation
and experimental work has shown a great promise in this technique
but systematic work is required to develop suitable applications
for the diverse applications of marine hydrodynamics.
Conducting
Research Addressing Fisheries,Aquaculture, and Water Quality
- Address
complex issues related to fisheries: MIT Sea Grant
is committed to achieving and maintaining sustainability
in fisheries and aquaculture through improved engineering
of fishing systems, assessments of the economic and social
impacts of regulations, increasing our understanding of the
ecological significance of fishing and aquaculture, and developing
better tools for determining the abundance and behavior of
commercially important stocks. We are encouraging research
that helps develop a comprehensive program for the successful
integration of a commercial aquaculture industry in the Northeast.
- Investigate
passive acoustics in fisheries research: The application
of passive acoustics to fisheries is an example of an emerging
research opportunity that also reflects the more general
need for ocean observatories. Passive acoustics offers a
unique tool not only to study fish, but also to simultaneously
monitor sources of noise pollution and study the impact of
man's activities on marine communities. Such research should
also aid in management of commercially exploited species,
improving techniques for identifying Essential Fish Habitat,
and providing non-invasive methods for stock assessment.
- Study
coastal water quality and its impact on marine resource: The
anthropogenic influences on harbors and coastal waters have
been a critical theme both for Sea Grant programs in Massachusetts
and throughout the nation. We are maintaining our focus on
three important issues: contaminated sediments, non-point
source pollution, and marine accident prevention. We will
be encouraging scientific, engineering and policy research
as it relates to responsible use of the coastal environment.
Developing
Food, Pharmaceutical, and Other Commercial Products Based on
Marine Natural Organisms
- Foster
research in biochemistry and molecular genetics of plants,
animals and microorganisms: Such research offers
potential use in producing food, pharmaceuticals and chemical
products (e.g. emulsifiers for remediation and adhesives);
mechanisms of growth and reproductive regulation and control;
disease diagnosis and control; and seafood safety.
- Research
into marine biology and genetically engineered products: We
are supporting research that can lead to improved bioremediation
strategies and better characterization of contaminant fates
in coastal ecosystems. Biosensors for marine applications
could address topics such as monitoring environmental quality
parameters of marine ecosystems; in situ sensing for aquaculture
quality control and optimization; monitoring and control
of biochemical engineering processes; developing new approaches
to biosensors using marine biomaterials; process control
for the production of natural materials; and antibody-based
approaches to biosensing.
- Examining
viruses of marine cyanobacteria as agents for marine biotechnology: Marine
photosynthetic cyanobacteria are at the base of the oceanic
food chain, and are of great importance in global carbon
and energy cycles. By characterizing the laboratory growth
and molecular biology of viruses of these cyanobacteria,
researchers hope to answer important questions about the
physiology and biochemistry of their marine cyanobacterial
hosts. It is likely that marine viruses will be critical
in developing biotechnology tools for marine cyanobacteria,
for use in environmental engineering, marine microbiology,
and related biotechnology applications. They also may be
the source of novel enzymes and proteins of more general
use in biotechnology and pharmaceutical industries. Sea Grant
is supporting research to develop the biotechnological aspects
of these unique organisms.
Educating
our Citizenry in the Opportunities and Challenges Associated
with Continued Expansion into the Marine Realm
- Promote
grade school and high school activities to foster marine
awareness: We are drawing on the success of our
recent projects in this area and encouraging organizations
and individuals to join us in our efforts. This includes
our program funded by the National Science Foundation, which
gives teachers and students hands-on opportunities in real
research, and Adopt-A-Boat, which partners K-12 classrooms
throughout New England with fishermen.
- Forge
links with local educational institutions for collaborative
efforts: We have experienced enthusiastic response
from the high schools and educational programs involved in
our outreach and education efforts. The willingness of these
institutions to support the involvement of their teachers
suggests a clear awareness of the need to incorporate hands-on
participation by young people in programs that facilitate
learning. Two very successful programs in this area include
public education with K-12 classes in hands-on aquaculture
programs and with middle and high school students in marine
robotics. The latter program is in part supported by the
Office of Naval Research.
- Effectively
communicate our research to the public: Our goal
is to effectively and thoughtfully translate science and
communicate our research to the public, educators and students,
and researchers. We will accomplish this through workshops,
symposia, exhibits, print and electronic media, as well as
via novel opportunities as these arise.
