Abstract:

RV Roger Revelle has been equipped with a Scientific Information System SIS which consists of a centralized multiprocessor UNIX computer server that receives, logs, processes, displays and broadcasts data in real time over an Ethernet network and via serial lines. This computer server is backed by an identical machine used for non real time data processing applications, and switchable to a real time mode should the on-line machine fail. Communication between the computer server, the scientific sensors, users computer workstations SUN Sparcstations, PCs and Macs or computer peripherals disks, ODWORM, and tape drives printers and plotters distributed throughout the ship, is achieved via the ships fiber optics network and the SIS wiring installed after the ship was delivered. Ship to shore email communication is handled through the off-line computer server with modem transmissions via INMARSAT. The scientific sensors connected to this Information System include GPS receivers, gyrocompasses, vertical reference units, meteorology sensors, sonars acoustic Doppler current profiler, multibeam swath bathymetry system, 12kHz3.5kHz bottomsubbottom profiler and a magnetometer. All the computers and sensors attached to the SIS network share a common time base provided by a time server synchronized to the GPS reference clock.
