The National Oceanic and Atmospheric Administration has developed an airborne mapper of coastal ocean salinity, and it works, NOAA scientist James Zaitzeff reports. A recent test set its accuracy range at about 1.5 parts per thousand salinity of the water surface, which means the system will be useful for coastal biologists and hydrodynamicists interested in studying coastal circulation patterns. Operated from small aircraft, the system can produce salinity maps at the rate of 100 km2 per hour, with 100-m spatial resolution.
