Revolutionary change in NOAA nautical chart production means more products, fas

NOAA's development of a new navigational chart processing system, designed to meet the changing needs of the maritime community, moves into initial limited production on September 21. The new system, which slims down the current map production process while it beefs up performance, represents a technological leap forward in creating the navigational charts used to speed ships and products safety through the nation's maritime transportation system.

NOAA and partners demonstrate success of multibeam sonar to detect and map deep-

Multibeam sonar, an echo sounding technology commonly used to map the seafloor, can also be used to map and detect gaseous seeps in the water column, according to scientists testing the technology on board NOAA Ship Okeanos Explorer last week in the Gulf of Mexico. Unlike other types of sonar, multibeam technology is able to survey a wide area of the seafloor and water column.

Oceanscience develop multi-profiler instrumentation boat to compare Teledyne RD Instruments and SonTek/YSI Acoustic Dopp

Oceanscience develop multi-profiler instrumentation boat to compare Teledyne RD Instruments and SonTek/YSI Acoustic Doppler Current Profilers (ADCPs)

Researchers at L'Institut de recherche d'Hydro-Québec (Hydro-Québec Research Institute, or IREQ) wanted to compare the performance of several acoustic Doppler current profilers commonly used for river discharge measurements. As new instruments become available, comparison measurements between new profilers and well known "benchmark" profilers are important to quickly validate the new instrumentation for field use. This process is often made difficult in the river environment where the profilers are deployed on small tethered boats; the boats are usually of varying design for the different profilers, which may bias comparison measurements made using them. In addition, as a result of size limitations it is not possible to deploy any two profilers simultaneously on the same tethered boat.
