The buoy is part of a national network that has provided operational meteo- rological and oceanographic data since 1986. AXYS Technologies Inc. (Sidney, Canada) manufactures and services the WatchMan control systems, sensors and telemetry integrated onto these buoys.

USE OF AUV FOR DEEPWATER SHIPWRECK SEARCH Garry Kozak (GK Consulting) describes the deployment of an AUV with side scan sonar and a high-resolution camera to map shipwrecks at 1,000 to 1,500 meters depth. EXPLORING ULTRADEEP HYDROTHERMAL VENTS IN THE CAYMAN TROUGH BY ROV Dr. Bramley J. Murton, Veit Hühnerbach (National Oceanography Centre) and Jo Garrard (Hydro-Lek Ltd.) summarize the results of an expedition that used the HyBIS ROV to find, image and sample 5,000-meter-deep massive sulfide deposits. TAKING THE TEMPERATURE OF THE ARCTIC WITH UNMANNED MARITIME VEHICLES Christian Meinig (NOAA Pacific Marine Environmental Laboratory), Dr. Michael Steele (Applied Physics Laboratory, University of Washington) and Dr. Kevin Wood (Joint Institute for the Study of the Atmosphere and Ocean) discuss the collection of 900,000 temperature measurements taken with Arctic Wave Glider AUVs.
