The NexSens CB-1250 Data Buoy is designed for deployment in lakes, rivers, coastal waters, harbors, estuaries and other freshwater or marine environments. The floating platform supports both topside and subsurface environmental monitoring sensors including weather stations, wave sensors, thermistor strings, multi-parameter sondes, Doppler current profilers and other monitoring instruments.

The buoy is constructed of an inner core of cross-linked polyethylene foam with a tough polyurea skin. A topside 50” tall stainless steel tower includes three 57-watt 12VDC semi-flexible solar panels, and a center 10” ID x 27.5” tall data well accommodates batteries, data loggers, sensors, and more. Three 8” pass-through holes with female NPT bottom threads allow for quick connection of instrument deployment pipes and custom sensor mounts. The stainless steel frame supports both single point and multi-point moorings.

The CB-1250 Data Buoy is optimized for use with NexSens data loggers. Wireless telemetry options include Wi-Fi, spread spectrum radio, cellular and Iridium satellite. Compatible digital and analog sensor interfaces include RS-232, RS-485, SDI-12, VDC, mA, and pulse count. The top of the instrument well includes 8 pass-through ports for power and sensor interface. Each port offers a UW receptacle with double O-ring seal for a reliable waterproof connection.

    • Hull Dimensions: 48” (121.92cm) outside diameter; 28” (71.12cm) tall
    • Tower Dimensions: 50” (127.00cm) tall, 7/8 tubular
    • Data Well Dimensions: 10.3” (26.16cm) inside diameter; 27.5” (69.85cm) tall
    • Weight: 300 lbs. (136.08 kg)
    • Buoyancy: 1250 lbs. (566.99 kg)
    • Hull Material: Cross-linked polyethylene foam with polyurea coating & stainless steel deck
    • Tower/Hardware Material: 316 stainless steel
    • Mooring Attachments: 1 or 2 point, 3/4” eyenuts
    • Solar Power: (3) 57-watt 12 VDC solar panels
      Questions & Answers
      What parameters can be measured with CB-1250 data buoys?

      NexSens data buoys are designed to simplify the connection of a wide variety of measurement sensors for weather, water quality, water current, waves and solar radiation. When combined with NexSens data loggers, these buoy-based sensors display measurement results online that are accessible to project staff and collaborators.

      Weather station parameters include air temperature, relative humidity, barometric pressure, wind speed, wind direction and more. Some advanced weather stations also incorporate GPS, tilt, accelerometer & compass sensors. Terrestrial and Underwater PAR sensors measure photosynthetic active radiation.

      Water quality sondes measure temperature, conductivity, depth, dissolved oxygen, pH, ORP, total algae (phycocyanin and chlorophyll), turbidity, and fluorescent dissolved organic matter (fDOM). The sondes also output several calculated parameters like salinity, specific conductance, total dissolved solids (TDS) and total suspended solids (TSS).

      Water current sensors used with data buoys are typically multi-beam acoustic doppler based and and measure currents, turbulence, wave height and wave direction. Wave data (height, period, direction) can also be measured using inertial-based sensors mounted on the buoy hull.

      How are weather sensors mounted to the CB-1250?

      Nexsens offers custom mounts for most industry met sensors including Airmar, Lufft, Vaisala, Gill and YOUNG. Sensor extensions are available based on the height of the sensor in relation to the water's surface. It is necessary to integrate a compass with any buoy-based met sensor to correct for wind direction due to buoy movement.

      How do I calculate a power budget for the data buoy?

      NexSens has a power budget algorithm to input variables like telemetry methods, measurement frequency, transmission frequency, instruments connected, months deployed, and location for any factory integrated system. With those variables, it is quickly determined whether a given buoy platform will have sufficient solar charging and battery reserve for autonomous deployment.

      Extreme Wave Heights, Ocean Winds Increasing Globally

      Around the world, extreme wave heights and ocean winds are increasing. The greatest increase is happening in the Southern Ocean, according to recent research from the University of Melbourne , and Dr. Ian Young corresponded with EM about what inspired the work. “Our main interest is ocean waves, and we are interested in wind because it generates waves,” explains Dr. Young. “Ocean waves are important for the design of coastal and offshore structures, the erosion of beaches and coastal flooding, and the safety of shipping.” Waves also have a role in determining how much heat, energy and gas can be trapped in the ocean. “The major reason why changes in wave height may be important is because of sea level rise,” details Dr. Young.

      NexSens CB-Series data buoys offers lineup from compact to powerful

      The 2014 line of CB-Series data buoys combines traditional NexSens Technology reliability with a number of new innovations designed to handle real-time data collection applications in waters from the Great Lakes to the Arctic. Each of the four CB-Series data buoys comes equipped with at least three solar panels, pass-through holes for water sensor deployment and topside mounts for weather sensors. But the buoys’ most exciting enhancement is the addition of a spacious, cross-compatible instrument well that protects your delicate electronics “The biggest change is we now have a large data well that allows us to integrate batteries, data loggers and other electronics,” said Paul Nieberding, Fondriest Environmental general manager.

      Real-time phosphorous sensor measurements tested on new Lake Erie data buoy

      Two new experimental data buoys bobbing on Lake Erie are giving scientists a chance to test new instruments while sharpening their watch over Lake Erie in harmful algal bloom season. A crew from the National Oceanic and Atmospheric Administration’s Great Lakes Environmental Research Laboratory and the University of Michigan deployed the buoys in western Lake Erie in the first week of June One will test a wind sensor that's new to the lab. The other will for the first time relay up-to-the-hour measurements of phosphorus levels back to the lab in Ann Arbor, Mich.
