Delivery of accurate timing to subsea instruments is one of the essential functions of the NEPTUNE Canada ocean observatory. In the context of an ocean observing system, ldquotimingrdquo is understood to mean the ability to timestamp data using a clock which is traceable to Universal Time Coordinates (UTC) within some desired level of precision. Transmission or delivery of timing means transporting...
Large volume neutrino telescopes require real time communications back to shore and a sizeable amount of power at the bottom to feed the detectors and the associated electronics. The telecommunications industry has developed a family of cabled products that have been cost optimized over the years. These submarine cables using optical fibres and a single copper conductor are ideal to achieve the transport...
To deliver high power and broadband communication to the ocean floor requires a number of changes to existing technology developed to bridge oceans from shore to shore. The dry-dry solution is well mastered and although it evolves over time following technological innovations, adapting it to become a dry-wet solution represents a major technical challenge. The cabled observatory system developed for...

The NEPTUNE observatory system has introduced a new technology approach, bringing the Internet to subsea cabled science observatory systems. The subsea nodes, providing subsea connection points provisioning data and power, provide a gateway between the permanent infrastructure and the instrumentation. The proven high reliability and long life of the subsea communications equipment offers the opportunity...
