CIMT: Within the Monterey Bay National Marine Sanctuary,
we are part of a multi-institution program (the Center for Integrated
Marine Technology) which aims to understand the linkages from wind
to whales. We are involved in the shipboard and remote sensing
components of this project. The CIMT
website has many more details.
ECOHAB: Within the Monterey Bay region, there are several
funded groups working closely together on the Pseudo-nitzschia/domoic
acid complex. We are funded
to develop in the field and laboratory an understanding of how
Si, N, C, and light interact physiologically to trigger DA production,
and to develop molecular markers for toxin production. Colleagues
at MBARI (C. Scholin), UCSC (D. Garrison, M. Silver, J. Goldman,
E. Rue), U. Maine (M. Wells), and MLML (G.J. Smith) are working on
related aspects, ranging from the role of metal availability, including
iron, to the transfer of toxin through the marine food web.
Cal-PReEMPT: In collaboration with Dr. Gregg Langlois at the California Department of Health Services, we are developing better monitoring tools for Harmful Algal Blooms occurring in the state of California, with funding from the NOAA MERHAB program. This is a multi-year effort involving Peter Miller (lead PI) and Mary Silver at UCSC, as well as Rick Stumpf (NOAA) and collaborators in Oregon and Washington states. See the Cal-PreEMPT webpage for details.
NASA projects: A physiological model of nitrogen utilization
by natural phytoplankton assemblages which can predict new production
in coastal waters using remotely sensed data (AVHRR and ocean
color data) or moorings was developed as part of NASA grant
NAG5-6563. As part of the EPA funded Coastal Intensive Sites
Network (CISNet; NASA grant NAG5-7632), we also developed
regional algorithms (pigments, CDOM, sediments, new production)
along a gradient of water conditions, from the blue-water stations
occupied off central California to the turbid waters of San Pablo
Bay. These methods are currently being applied to ongoing projects,
including CoOP and CIMT.
CoOP: As part of an NSF-sponsored Coastal Ocean Projects
program, we were part of a 5-year study of coastal productivity
(The Role of Wind Driven Transport in Shelf Productivity). This
program has 3 field years, with a combination of instrumented
moorings and cruises, followed by two years of data assimilation
and development of a coupled physical-biological model. We are
responsible for the bio-optical component and shipboard process
studies, and is developing regional algorithms for new and primary
production. More information is available here.
As part of the CoOP program River Influences on Shelf Ecosystems
(RISE), we are currently evaluating the role of the Columbia River
Plume in modulating coastal productivity. This program is also
5 years, with 4 field seasons and an integrated modeling component.
More information is available here.
