Summary
A microprocessor-based data-acquisition system has been developed to meet the requirements of a range of oceanic sensor inputs. The system described is specially suitable for low-power, long-period underwater applications. Details are given of the hardware and software design, and examples of interface to propeller current sensor and pressure transducer. Preliminary field results in the Northern Great Barrier Reef are described.
