Model NB-84 Buoy System

Large Platform for Meteorological and Oceanographic Data Collection/Telemetry

Low Roll For Accurate Environmental Measurements. Minimum Mooring Tilt.

Stable Platform for At-Sea Boarding

and Efficient Telemetry Performance

Wide Variety of Sensor, Power and Transmission Options
NB-84 Buoy in Canadian N. Atlantic


The larger size of the NB-84 provides for larger sensor arrays, power sources and telemetry gear. The NB-84 can be equipped with an air-cooled diesel generator for long term deployments. Large compartments protect onboard power and electronics packages from the elements while easy access is provided through a watertight hatch. Various VHF, UHF, satellite, and cellular transceivers can be mounted on the buoy for telemetry purposes.

Moored with BuoyTec's Elastic Mooring Array, the NB-84 has a small watch circle and minimal roll, which minimizes interference with on-board data collection such as anemometer readings, ADCP profiling and data telemetry transmissions.
