Description:A digital recording, self-contained tide measurement system for Continental Shelf oceanography is described. Design parameters, construction techniques, sensor calibrations, and system tests are discussed. Pressure and temperature are measured through the use of a high precision quartz crystal and a precision epoxy-coated thermistor. Data are recorded on digital cassettes with a capacity of 11 million bits. Power consumption is extrepiely low with in-situ recordings of 400 days possible while using an alkaline power source. Time base is supplied by a precision quartz crystal binary clock. Temperature corrections for pressure and time are given. Calibration values are given with coefficients for each pressure transducer stated. Results of MESA deployments are shown, with tide and temperature records.
