Northridge, UCSB Win $4.6 Million for Coral Reef Project to Study
Threatened Ecosystems Near Tahiti
The National Science Foundation (NSF) has selected Cal State Northridge and
UC Santa Barbara as the joint recipients of an "unprecedented" $4.6 million,
six-year grant to establish a long-term project studying the coral reefs of French
Polynesia, an effort expected to add volumes to scientific understanding of ominous
changes in global coral reef communities.
CSUN marine biologists Peter Edmunds and Robert Carpenter, working with two other
principal investigators from UC Santa Barbara, will conduct research centered at
the University of California's field laboratory on the north shore of Moorea,
located west of Tahiti in the Windward group of French Polynesia's Society
The research will help scientists better understand coral reef processes affecting
the reef ecosystem, the nature of animal and plant community structure and diversity
in the famously colorful coral reefs, and the factors that determine the abundance
and dynamics of related oceanic populations.
"This understanding," said Phil Taylor, director of NSF's biological oceanography
program, "will allow us to make more accurate predictions of how coral reef
ecosystems respond to environmental change, whether human-induced or from natural
Among the oldest and most diverse of the earth's ecosystems, coral reefs provide
natural storm barriers for homes and beaches as well as habitat for more species
per unit than any other of the planet's marine environments. They support commercial
fisheries, tourism and recreation jobs. Often called the "medicine cabinets of the
21st century," the reefs' plants and animals are important sources of new
The Northridge/UCSB project represents the first and only coral reef Long Term
Ecological Research (LTER) site supported by the federal government. Designed to
compare organic productivity and diversity among terrestrial, aquatic and marine
systems, NSF's LTER network previously included an Antarctic project as its only
other marine site.
NSF's grant is of "unprecedented magnitude" for research in coral reef biology,
Edmunds said the grant could not have come at a more critical time.
"Coral reefs are facing a profound threat in the next 10 years or more, in terms
of global climate change," he said.
Climate changes are warming sea water at a relatively fast rate, resulting in
two kinds of events. "One is conspicuous and striking," Edmunds said. "Corals are
dying by ‘bleaching,' that is, turning white. They die if they remain white for
several weeks at a time." This calamity has already killed many hundreds of square
miles of coral reefs in both Pacific and Caribbean waters.
"The second is more subtle," he continued. "The changes in this kind of event are
slow, such as diseases that begin to take small numbers of corals every year, year
in and year out."
Sewage and pesticides form an unholy alliance with gradual changes in water
temperature, possibly affecting the corals' ability to reproduce. Both kinds of
events may presage the slow death of an entire ecosystem unless enough is learned
to turn that tide.
Carpenter and Edmunds have more than 40 years of combined experience in field
research at sites as far-flung as Key Largo, the Australian Great Barrier Reef,
the kelp forests off Santa Catalina Island, and in Hawaii, where Carpenter currently
is engaged in a project investigating the effects of water flow on the island's
Planning for the project gets underway this fall, but the real work for Carpenter
and Edmunds will begin in spring 2005. A reconnaissance trip is planned for January,
and the bulk of the project's first-year objectives will be set up in April or
Edmunds will be responsible for the direct study of stony corals, described by
NSF's Taylor as "the foundation upon which tens of thousands of other species rely."
The CSUN scientist will determine how much of the ocean bottom the corals cover,
and how such coverage changes over a ten-year time scale. Most importantly, he
will work to illuminate the mechanism of the changes.
Carpenter will focus on the role of oceanic currents and water flow, coral reef
metabolism, the health of the ecosystem, the interaction of water flow with the
reefs and the dynamics of coral reef production. The UCSB marine biologists--Sally
Holbrook and Russell Schmitt--are eminent fish ecologists, with interests primarily
in the abundance and dynamics of reef fish populations.
"What distinguishes this project from superficially similar projects around the
world," said Edmunds, "is that they are able to record change, but we have the
financial support to go beyond that to address the mechanism and process of change
