The Ocean Observatories Initiative at the University of Washington

Installation Success
Design + Engineering
Maintenance Cruise

This is the first time a high-definition camera has been placed on the ocean floor that is capable of delivering the video signal in an uncompressed format over an Internet-style 10 GB/second fiber optic network. The hardware did not exist until now.

To turn it on, have the systems work flawlessly, and to get data immediately was exhilarating.


The University of Washington's Cabled Array of the NSF OOI extends continuous high-bandwidth communications (tens of Gigabits/second) and power (tens of kilowatts) to a network of instruments widely distributed across, above, and below the seafloor in the northeast Pacific Ocean.

As the world's first ocean observatory to span a tectonic plate, this facility provides a constant stream of data in real time from the ocean, on the seafloor, and below the seafloor within the Juan de Fuca plate.

The oceans of Earth are crucial to the quality of life on land. Yet they are mysterious, dangerous, and unexplored. The mission of the NSF Ocean Observatories Initiative is to launch a new era of human discovery within the world's oceans through electrical power and high speed internet connectivity in large portions of the global ocean. Land-based scientists, engineers, educators, and the public can interact remotely with ocean events as if they were actually in the ocean environment — events such as erupting volcanoes, migrating fish, major earthquakes and storms, powerful currents, blooms of microscopic life, and subtle climatic variability.

Location of high power and bandwidth moorings with profiling capabilities on the Cabled Array. One mooring will be placed at the base of Axial Seamount, providing measurements key to examining flow over rough topography, El Niño and La Niña events, and the Pacific Decadal Oscillation. A second mooring will be located at the base of the accretionary margin outboard from Hydrate Ridge. This mooring forms an array with three surface and three subsurface (two of which are cabled to the network) moorings that are part of the Coastal Scale Endurance Array.
