Slogger Acquisition and Logging System

This page describes the Slogger data acquisition and logging system. The name Slogger is created from the words "Shipboard Logger". Slogger performs basic acquisition of serial, analog, and frequency data from a myriad of devices, sampling data in one minute periods. This data is averaged, and the mean, min, and max of each sampled item logged to disk in netCDF format, and then broadcast out a serial port in NMEA 0183 format.
