NEPTUNE
Overview
The NEPTUNE Canada project, along with sister project, VENUS, offers a unique approach to ocean science.[1] Traditionally, ocean scientists have relied on infrequent ship cruises or space-based satellites to carry out their research. But NEPTUNE Canada is changing this by building the world’s first regional-scale underwater ocean observatory that plugs directly into the Internet.[1] When completed (by late 2009), people everywhere will be able to surf the seafloor, and ocean scientists will be able to run deep-water experiments from labs and universities anywhere around the world.
NEPTUNE is an acronym for North-East Pacific Time-series Undersea Networked Experiments. The North-East Pacific is home to the Juan de Fuca plate—smallest of Earth’s 12 tectonic plates. Its small size and close proximity to the coast gives NEPTUNE Canada a unique opportunity to observe tectonic processes. NEPTUNE Canada is built to provide continuous observations for 25 years. The time-series data gathered will allow scientists to study long-term changes over the life of the project. Instruments comprising the undersea observatory will operate at depths ranging from 17 to 2,660 m. Hundreds of instruments will be connected to the Internet by way of shielded cables carrying both power and fibre-optic communication lines. A database will archive and provide networked access to all archived data. Taking advantage of this platform, scientists collaborating with NEPTUNE are expected conduct thousands of unique experiments over the life of the project.
Status
- In 2007, NEPTUNE Canada laid approximately 800 km of power transmission and fibre optic communication cables over the northern part of the Juan de Fuca tectonic plate off the west coast of Vancouver Island in British Columbia. The University of Victoria hosts both the NEPTUNE Canada and VENUS projects along with the Data Management and Archiving System that is responsible for all data processing, from data acquisition to archiving to providing near real-time web access.
- The NEPTUNE project was selected as one of the five most significant science projects of the year in 2008 from The Economist.[2]
- In June 2008, the NEPTUNE project received and successfully tested the world's first “Internet-operated deep sea crawler,” created by a team of ocean scientists at Bremen's Jacobs University, will help researchers measure conditions such as temperature, salinity, methane content and sediment characteristics at the seafloor. The crawler “crawls” on dual tractor treads, which allow a full range of forward, backward and turning movement. Including its titanium frame, drive motors, sealed electronics chambers, wiring, lights, HD video camera, and sensors, the unit's out-of-water weight is 275 kg. With syntactic foam floatation blocks attached, this is reduced to an in-water weight of 40 kg. One unique feature is its control interface, which plugs directly into the Web. Interested people will be able to tune in to a live sea floor crawl on the NEPTUNE website.
- Late September 2008 NEPTUNE Canada's first fully-instrumented instrument platform was deployed by ROPOS from the Canadian Coast Guard Ship John P Tully in Saanich Inlet and connected to the VENUS Saanich Inlet node. This platform will be recovered in early 2009 and reconfigured for deployment at Endeavour Ridge during the summer of 2009.
- A similar observatory will be installed off the west coast of the states of Washington and Oregon. The University of Washington will lead the Regional Scale Nodes component of the NSF's Ocean Observatories Initiative.
- July-September 2009, the main science nodes were installed along with 11 instrument platforms and over 60 scientific instruments.
