Ocean Sentinel NOMAD™ MetOcean Buoy

The NOMAD MetOcean Buoy is a reliable data collection buoy for extreme weather conditions & remote deployments.

The NOMAD (Navy Oceanographic Meteorological Automatic Device) hull was originally designed in the 1940s for the U.S. Navy’s offshore data collection program. The hull was adapted by both U.S. National Data Buoy Centre (NDBC) and Environment Canada to be equipped with met sensors, telemetry payloads and deployed along the extensive coasts of both countries.

AXYS made modifications to the NOMAD hull to improve its functionality as a MetOcean buoy, which was adopted by Canada’s Atmospheric Environment Service for deep ocean stations off the East and West coasts of Canada. A full complement of meteorological and oceanographic sensors can be accommodated, while a wind turbine, solar panels and rechargeable batteries provide power to operate the electronics payload.


There is sufficient space on and in the hull to carry additional payload systems, including AXYS’ WindSentinel and Ocean Sentinel configurations.
