This paper discusses the use of the IEEE 1588 standard in ocean observatories. The
performance result of prototype implementations of this standard in an Ethernet Marine Sensor
Network (MSN) is presented. The performance tests emulate an underwater-cabled
observatory with a Master Clock synchronized with GPS, located in an on-shore station, and
with underwater instruments requiring high-precision PPS (pulse s−1) signals for
synchronization purposes. These signals will be provided to the underwater station by an
IEEE 1588 GPS Emulator connected to the observatory’s Local Area Network (LAN). The
experimental setup emulates the underwater-cabled observatory OBSEA where this
technology will be installed due to synchronization requirements of marine instruments such
as ocean bottom seismometers.
