1999 Projects: Upper ocean biogeochemistry

Biogeochemical responses to changes in climate and ocean circulation

Project lead/manager: Francisco Chavez
Project team: Gernot Friederich, Russell Hopcroft, Kenneth Johnson, Raphael Kudela, Reiko Michisaki, and Tim Pennington

This project encompasses ongoing, long-term studies on the biogeochemical responses of the Central California marine ecosystem to climate and ocean variability. The data used in these investigations come from satellite instruments, shipboard measurements, and moorings equipped with novel sensors and telemetry. By the year 2000 we will have collected a ten-year time series of shipboard data that will include the 1997-98 El Niņo—a particularly strong event—and the La Niņa event developing in the tropical Pacific as of late-1998. At the end of an intensive period of observation from 1997 to mid-2000, we plan to fully transfer the task of routine shipboard time-series measurements to satellites, instrument-equipped moorings, and other remote-sensing platforms such as autonomous underwater vehicles (AUVs).

We will work on two collaborative modeling efforts. The first assimilates satellite information and predicts new and total primary production. The second is based on numerical modeling. Researchers from MBARI, the Naval Postgraduate School, and the University of California, Los Angeles, will develop numerical models for coupled ocean-atmosphere processes in the Monterey Bay region and the northeast Pacific. MBARI will provide data to initialize the models and real-time oceanographic data to test modeling results. MBARI also will contribute data on mean climate conditions for chemical and biological fields and develop fundamental equations describing biological-physical coupling. The long-term goal is to use the output of the physical models as inputs for biogeochemical models, thereby advancing our capacity to predict three-dimensional biological and chemical fields. Results from the modeling efforts will define future process-oriented experiments.
