New Navy Buoys Demonstrate Global Remote Sampling Capability
1990
Selsor, Harry D.
Over the past two years the number of surface and air dropped expendable bathymetric observations received by the Navy has decreased from about 125 to 50 observations per day. Subsequently, the Navy has been investigating new, more economical, techniques for remote sampling of environmental data using satellite-reporting, air deployable, drifting data buoys equipped with a variety of sensors. A buoy that measures air temperature, sea surface temperature and barometric pressure for 90 days has been developed and is now in operational use. Testing of a 100 m thermistor cable on the buoy has demonstrated a 45-day potential. Additional sensors for wind speed, wind direction, and broadband ambient noise measurements are being added. Coupled with a new prototype satellite reporting system, a global, near real time, oceanographic observing and reporting system is now being demonstrated. this paper describes the Navy's test of such buoys and their application to a global remote sampling capability.
