Two self-recording oceanographic data collection systems based on microprocessors are highlighted. Descriptions are given of the Ocean Data Equipment (ODEC) model 302A CSTD unit, which measures ocean conductivity, salinity, and temperature as a function of depth (from which acoustic sound speed is calculated), and the InterOcean Model S4 current meter, which measures ocean current speed and direction as a function of depth or time. Networked with the Apple Macintosh microcomputer, the acquisition, processing, and analysis of CSTD and current data become dependable and virtually automatic. Communication between the Macintosh and the oceanographic probes, as well as data processing, is accomplished with commercially available software. Ease of use is accomplished in both instruments through probe features and the Macintosh user interface. The components and interfacing of each system are detailed. Examples of output and field experiences with this instrumentation suite are provided.
