CB-950 Data Buoy

The CB-950 offers sufficient power and sensor payload for demanding instruments including video cameras, ADCP’s and more.



Solar powered buoy


The platform integrates three 44-watt solar panels on the tower with space for up to three 28 A-Hr batteries in the data well.

Solar powered data buoy


The stainless steel tower includes a top mounting plate for solar marine lights and radar reflectors. Mounts are also available for weather sensors, video cameras and other topside instruments.

Data logger and telemetry well

Data Well

A 10-inch diameter by 26-inch tall data well provides a watertight housing for batteries, data loggers, sensors, and other hardware.

Data buoy sensor connections


The data well lid provides pass-through connections for sensors, power, venting, and more. When integrated with the optional NexSens X2-CB data logger, the system is truly plug-and-play.

Deploy underwater sensors

Top-to-Bottom Ports

Three 6-inch pass-through ports allow for sensors to be mounted underwater while securely routing the cable. Instrument deployment pipes and custom sensor mounts attach to 6-inch NPT bottom threads.

data buoy navigation beacon

Solar Beacon

The optional solar marine light has a one to four nautical mile range and securely mounts to the buoy top plate for maximum visibility.

data logging buoy

Data Logging

The X2-CB data logger replaces the standard pass-through data well lid for turnkey systems. Alternatively, 3rd party data loggers can be integrated by the user inside the data well.

cellular, radio and satellite telemetry

Wireless Communications

Communication options using the X2-CB data logger include Wi-Fi, radio-to-shore, cellular, and Iridium satellite.

compact durable data buoy

Built to Last

Constructed of cross-linked polyethylene foam with a heavy polymer skin and an indestructible stainless steel frame, the CB-950 is designed for years of service.

Case Studies

The Coral Reef Early Warning System (CREWS)

Corals around the world are under threat. The buoys of the Coral Reef Early Warning System (CREWS) help face that threat, providing the entire world with weather patterns and data about climate change from their home in the Caribbean Sea. Since June 2018, a new, state-of-the-art oceanographic buoy has added ocean state and weather data in near real-time to the CREWS system—all accessible from a computer or smartphone. A better […]

Liberty Island Restoration Project

In 2010, a design for the Liberty Island Restoration Project was completed and implemented, creating open water channels, emergent tidal marsh lands and floodplain habitats to sustain water fluctuations. The work was done in an effort to help wildlife living in the California Delta as well as fish species including delta smelt and Chinook salmon. But beyond just putting new marshes in place, it was important for those working on […]

Developing Alaska Buoy Platform

Recent studies into global climate change have identified an increase in Arctic warming rates. These are linked to increased trends toward more sea ice loss that are leading many to anticipate the Arctic will become a more popular shipping route. Coinciding with this expected expansion in use, agencies in the U.S., including the National Oceanic and Atmospheric Administration, are preparing for more operations in the Arctic. For NOAA, that means […]
