Regional Scale Nodes — RSN

The Ocean Observatories Initiative at the University of Washington

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.

Overview

The University of Washington's Regional Scale Nodes or RSN of the NSF OOI will extend continuous high-bandwidth (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.

The University of Washington was selected to begin leading the regional component of the NSF Ocean Observatories Initiative: The Regional Scale Nodes (RSN). This cabled underwater research facility will be constructed off the Oregon and Washington coastlines.

The RSN will extend continuous high-bandwidth (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 will provide a constant stream of data in real time from the ocean, on the seafloor, and below the seafloor within the Juan de Fuca plate.

Location of high power and bandwidth moorings with profiling capabilities on the RSN. 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 RSN) moorings that are part of the Coastal Scale Endurance Array.
