There is a long history in California of monitoring fisheries arid fish catches, beginning in 1914 with the establishment of the California Department of Commercial Fisheries. The mission of this agency was to collect fisheries statistics, develop improved catch and processing methods, and study life histories of commercially important stocks (Hewitt, 1988~.

Primary production is measured daily; continuous measurements of temperature, light, chlorophyll, and dissolved oxygen are taken; and Acoustic Doppler Current Profiles of current measurements and acoustic backscatter are collected. Chlorophyll, phaeophytin, salinity, dissolved oxygen concentration, nitrate, nitrite, phosphate, silicate, and water transparency data (to depths exceeding 500 m)

At the time, during the late 1940s and early 1950s, the inclusion of physical oceanography in a fisheries investigation was a unique idea, and one that is credited to the influence of Harold Sverdrup. Sverdrup was also instrumental in designing the interdisciplinary graduate curriculum at Scripps Institution of Oceanography, where students in all earth science disciplines take a broad range of courses.

In addition, because successful long-term analysis depends on using the same measurements over time, this agreement led to an emphasis on using relatively simple, but accurate and verifiable, measurements that would remain valid over the long term. The program consistently avoided sophisticated, state-of-the-art approaches where methods were likely to change rapidly and create intercalibration problems.

However, all participants shared a common purpose reflected in the program's central research question, which could be answered only by combining data from all three agencies. This structurally reinforced cooperation was facilitated by frequent informal conferences where investigators shared data, opinions, and arguments.

These lessons include: · Build the program around simple, yet challenging questions that cut across discipline boundaries and foster a shared purpose among program scientists. · Create an explicit interdisciplinary focus by framing research questions so that each discipline requires data from other disciplines to achieve its goals.

· Emphasize the importance of data quality as a key prerequisite for successful data interfacing and productive interdisciplinary research. REFERENCES Baxter, J.L.
