COASTAL RESEARCH PROJECT AT UC SANTA CRUZ RECEIVES MAJOR BOOST IN FUNDING
For Immediate Release
SANTA CRUZ, CA--For the past two years, researchers at the University of California,
Santa Cruz, have been studying and monitoring coastal ecosystems as part of a long-term
collaborative research project involving four major universities in California and
Oregon. Now the organization funding the project, the David and Lucile Packard Foundation,
has augmented its original $17.7 million grant to the four institutions with an additional
$2,285,000 grant for the UC Santa Cruz portion of the project.
Called the Partnership for Interdisciplinary Studies of Coastal Oceans (PISCO), the
project involves researchers at UCSC, UC Santa Barbara, Oregon State University (OSU),
and Stanford University. PISCO researchers are studying the communities of organisms
in nearshore habitats along a 1,200-mile stretch of coastal waters from Oregon to
southern California. The nearshore zone, from the shoreline out to about six miles
off shore, is heavily influenced by human activities, but the natural dynamics of
the ecological communities in this zone are not well understood, said Peter Raimondi
and Mark Carr, UCSC's principal investigators on the PISCO project.
UCSC scientists led by Carr and Raimondi are responsible for all of PISCO's field
research in northern and central California, as well as some of the research in southern
California. UCSC's portion of the original five-year grant was $3.2 million, and
the augmentation brings the campus to the same level of funding as the other partner
institutions.
"This significant augmentation from the Packard Foundation recognizes the outstanding
work spearheaded by UCSC, as well as the potential for significant advances in understanding
coastal ecosystems," said Jane Lubchenco, a PISCO principal investigator at
OSU.
PISCO researchers have established a coordinated ecological monitoring network using
identical research protocols at 57 study sites along the California and Oregon coasts.
Their work monitoring populations of a wide range of organisms at these sites has
already yielded valuable information about how different populations responded to
the most recent El Niño, which brought changes in ocean currents, water temperatures,
and climate conditions.
The new funding is enabling UCSC researchers to expand their activities in several
critical areas, including molecular genetics, nearshore oceanography, and selective
tagging of marine species, Raimondi said. In their studies of coastal fish populations,
for example, they are pursuing several new lines of research on species that inhabit
the kelp beds and rocky reefs in the subtidal zone. One approach involves using molecular
genetics to study the genetic linkages between populations at different sites. This
work will make use of a new genetics facility established on the UCSC campus using
funds from the PISCO grant and from the Division of Natural Sciences.
"A major thrust of PISCO is to understand the linkages between different populations
of organisms along the coast and the scale of movement of individuals between those
populations," Raimondi said. "In rockfish populations, for example, we
suspect that larvae from one location disperse to completely different locations
where they grow into adults."
Since fish larvae are carried more or less passively by ocean currents, studying
the movements of water along the coast will also help shed light on patterns of larval
dispersal, Raimondi said. In addition, the researchers plan to use innovative tagging
techniques to follow the movements of individual fish. Using natural or introduced
minerals that are incorporated into tiny bones in the ears of the fish, the researchers
hope to tag large numbers of larvae and follow them to adulthood.
"We're not sure all these approaches will work, so these are high-risk, high-reward
endeavors that we would not be able to undertake without the augmented funding from
the Packard Foundation," Raimondi said. "Our initial allocation supported
the basic fieldwork of monitoring populations in the intertidal and subtidal zones.
Now we can do more detailed surveys and take a closer look at processes like the
dispersal of larvae and the recruitment of new individuals into populations."
One goal of PISCO is to provide scientific findings that can be applied to the management
of coastal ecosystems, which are heavily influenced by commercial fishing and other
human activities, Carr noted. The new funding is enabling the PISCO group at UCSC
to hire a full-time policy coordinator whose role will be to disseminate information
to resource managers and policy makers. The policy coordinator will also keep abreast
of management problems and help direct the research program to address key management
issues.
Many commercially important species of fish are found in the subtidal zone, including
the various kinds of rockfish. One management issue UCSC researchers are already
investigating is the role of marine reserves in maintaining healthy populations of
these fish. PISCO studies of fish populations in the subtidal zone include sites
inside reserves where fishing is prohibited and in areas subject to commercial and
recreational fishing.
"UCSC is uniquely poised to look at the effects of marine reserves, because
there are several local reserves that are no-take zones for fishing," Carr said.

The David and Lucile Packard Foundation, based in Los Altos, California, is a private
family foundation established in 1964. It provides grants in several major program
areas, including science, population, conservation, arts, and children and community.
