The University of Washington has been
allocated $2.2 million for a planning phase to develop detailed
engineering specifications for a cabled underwater research facility to
be built off the coast of Washington and Oregon, and associated with
the Juan de Fuca tectonic plate. The facility 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. (Image by University of Washington)
- This underwater research facility
will be the world's first ocean observatory to span a tectonic plate.
It will provide a constant stream of data in real time from throughout
the water, on the seafloor and below the seafloor associated with the
Juan de Fuca plate.
- The facility could help unlock secrets about the ocean's
ability to absorb greenhouse gases and how seafloor stresses cause
earthquakes and tsunamis along Pacific coastlines. Investigations could
lead to powerful new medicines derived from microbes and animals that
thrive in the extreme environments of the region's underwater
volcanoes. Data collected and transmitted in real time by the network
will help improve weather forecasting and management of valuable fish
stocks such as salmon.
- The underwater research facility will initially have four
sites, or nodes, connected by more than 850 miles of cable for power
and communications that will send data, video, still imagery and
instructions to and from shore nearly instantly, via the Internet.
Instruments on the seafloor or on moorings tethered to the seafloor
will be connected to the nodes. Rather than going to sea in ships and
submersibles, scientists using the network will work from land-based
computers and laboratories to analyze changes in the oceans and to send
instructions to undersea robotic vehicles plugged into the network. See
www.ooi.washington.edu.
- Incorporating the vision of the NEPTUNE (North East Pacific
Time-integrated Undersea Networked Experiments) Project, an undersea
research facility on the Juan de Fuca plate has been envisioned and
discussed for one and a half decades by UW oceanographer John Delaney,
now director, principal investigator and chief scientist of the UW
observatory program. The idea has been covered by media outlets such as
the Seattle Times, Seattle Post-Intelligencer, Oregonian, Los Angeles
Times, Wired magazine and Science magazine.
- A global community of users will have unprecedented
interactive access to the oceans. Educators, students and the general
public will be welcome to "join" scientists as they explore the ocean,
with access to video and data via the Internet, similar to the live
broadcasts from the seafloor available in 2005 during the VISIONS '05
expedition. See www.visions05.washington.edu and watch one of the broadcasts at http://www.uwtv.org/programs/displayevent.aspx?rID=4157.
- With the planning money, the UW will develop detailed
engineering specifications, engage interested parties and seek permits.
If the needed approvals and permits are obtained, the underwater
research facility would be in line to receive $130 million of National
Science Foundation money, through the Joint Oceanographic Institutions,
over six years for construction.
- The entire surface of the Earth is covered with tectonic
plates. Movement of these plates controls the location of continents,
volcanoes, mountain ranges, earthquakes, metal deposits and many energy
deposits. Understanding plate dynamics is essential to optimizing
benefits and mitigating the risks of living on Earth.
- The Juan de Fuca plate, one of the Earth's dozen or so major
tectonic plates, was chosen because of its relatively small size and
its proximity to North America. The many natural processes that occur
in proximity to the plate -- major ocean currents, active earthquake
zones, creation of new seafloor, rich environments of marine plants and
animals -- are representative of those that occur throughout the
world's oceans. Parts of the plate experience earthquakes and volcanic
eruptions and are dotted with eerie spires and chimneys venting water
as hot as 700 degrees F. The plate includes some of the most
geologically and biologically active sites in the global network of
mid-ocean ridges and hosts some of the most extreme environments on
Earth. See www.neptune.washington.edu.
- A complementary Canadian program, managed by the University of
Victoria, is building a cabled network off British Columbia on the
Canadian portion of the Juan de Fuca plate. See: http://www.neptunecanada.ca/
- The UW's collaborators in the underwater research facility
will include researchers at the University of Oregon (Douglas Toomey),
Oregon State University (Jack Barth), Arizona State University (Deirdre
Meldrum), University of California San Diego's Scripps Institution of
Oceanography (John Orcutt), Woods Hole Oceanographic Institution (Alan
Chave) and many others.
- The cabled regional nodes developed by UW are part of a larger
undersea facility coordinated by the Joint Oceanographic Institutions
with funding from the National Science Foundation's Ocean Observatories
Initiative. The Joint Oceanographic Institutions is a consortium of 31
oceanographic research institutions that serves the U.S. scientific
community through management of large-scale, global research programs
in the fields of marine geology, geophysics and oceanography. The OOI
will construct a networked infrastructure of science-driven sensor
systems to measure the physical, chemical, geological and biological
variables in the ocean and seafloor. The OOI will provide continuous,
interactive access to the ocean for the oceanographic research and
education communities. The OOI's observatory elements will address
science questions on coastal, regional, and global scales, linked by a
common instrument, infrastructure and information management system.
