Jan. 8, 2008: A sound-transmitting transponder that will form part of the long baseline navigation system on the sea floor is deployed over the fantail. The ship slowly moves away from the transponder as about 200 meters of tether wire is paid out. The end of the wire is then attached to an anchor weight, which is kicked into the water, and the transponder sinks to the seafloor to begin its work. (Courtesy of Dan Conrad)
