A temperature profiler

Abstract

An instrument developed for measuring temperature profiles at sea in depth or time scales is described. PC-based programming offers flexibility in setting up the instrument for the mode of operation prior to each cast. A real time clock built into the instrument enables setting up the desired time interval for data acquisition when moored at a particular place. Data acquired in either mode is stored in the memory of the sea-probe instrument. At the end of each cast, data is downloaded into the PC for processing and further analysis. Data acquired during a recent cruise has been processed and analysed, and the instrument behaviour studied vis-a-vis on-board CTD system. The performance data are presented
