| Abstract: | A microcomputer-controlled culturing system developed to simulate temperature and salinity fluctuations in an estuary is described. The system consists of a microcomputer, interfacing hardware, a continuous culture apparatus, and system software. The system can regulate the temperature and salinity of a continuous phytoplankton culture based on user-defined models of the physical environment and particle transport in a natural environment. The microcomputer also provides efficient data acquisition and data storage. The system was designed to facilitate expansion and modification and can easily be adapted to accomodate various studies of phytoplankton production. Details of a simulation and representative data are presented. |
