Dear Robotics Colleagues:

   On June 1, 2009  we completed our first 10,900 meter depth dive with
our new Nereus robotic underwater robot vehicle at 11 22.1N 142 35.478E
in the Mariana Trench in the Western Pacific.  This 26 hour dive was
comprised of a 8.5 hour descent to 10,900m, a 10.75 hour  bottom
interval during which we had live video via fiber-tether multi-gigabit
optical telemetry and performed geological and biological sampling with
Nereus's robotic arm under the direction of our science party, and a 6.5
hour autonomous ascent to the surface.

   We conducted a total of seven dives on this expedition, two of which
were to the bottom of the Mariana Trench at 10,900 meters depth.

   The Nereus project team is from the Woods Hole Oceanographic
Institution, the Johns Hopkins University, the U.S. Navy, and
the University of Hawaii.

   Some project-related links are below.
