This project will evaluate the role of bacteria in the cycling of matter in seawater, whether the organic matter is dis- 

 solved, particulate, produced in situ, or terrestrially derived. The assessment will be made by measuring (1) fluxes 

 of dissolved and particulate matter into bacterioplankton, (2) mineralization rates of organic matter, (3) growth 

 rates of heterotrophic bacterioplankton, and (4) growth of bacteria on particles and in the free state. 



Primary Production, Nutrients, and Oxygen in the Southern California

This project will determine (1) the spatial and temporal variation in planktonic primary production; (2) the sinking 

 flux of particulate biogenic carbon to depth; and (3) the calibration of satellite chlorophyll images in order to calcu- 

 late primary production synoptically over a larger area than can be done from ships. The objective is (1) to develop 

 a mass balance for carbon and nitrogen in basins of the California Bight, and (2) to provide a basis for evaluating 

 supply and decomposition rates of organic matter and the distribution of these processes in the basins.
