The NexSens CB-950 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 45” tall stainless steel tower includes three 44-watt 12VDC semi-flexible solar panels, and a center 10” ID x 25.5” tall data well accommodates batteries, data loggers, sensors, and more. Three 6” 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-950 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: 42” (106.7cm) outside diameter; 26” (66.04cm) tall
  • Tower Dimensions: 45” (114.30cm) tall, 7/8 tubular
  • Data Well Dimensions: 10.3” (26.16cm) inside diameter; 25.5” (64.77cm) tall
  • Weight: 285 lbs. (129.27 kg)
  • Buoyancy: 950 lbs. (430.91 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) 44-watt 12 VDC solar panels
Questions & Answers
Are there alternatives to placing sensors in deployment pipes and within cages?

Yes, instruments can be mounted along stainless steel mooring lines via the MC-600 mooring cable clamp when measuring at multiple depths within the water column. A 2-point mooring design is recommended in these situations to prevent the sensor line from tangling with the anchor lines.

Are there any aspects of this platform that are not waterproof?

The data well lid includes a passive Gore-Tex vent to allow for battery outgassing. If the buoy will be deployed in high energy environments where there is a potential for submersion, we recommend upgrading this vent to the UW-PRV pressure relief valve for added protection from water ingress.

How are water quality sondes mounted to moorings?

When measuring near the surface, water quality sondes can be housed inside a slotted deployment pipe that is threaded directly to the bottom instrument well on the buoy hull. This allows instrument access for periodic cleaning and calibration without having to pull the buoy out of the water.

If the project requires measurements at depth or at multiple depths, NexSens offers instrument clamps and mooring cages for mooring lines, as well as bottom platforms when sondes need to be bottom referenced instead of surface referenced.

How do I connect sensor cables to the data buoy?

For customer integrations, cables can be run through one of six ports on the passthrough data well lid and secured with a supplied cable gland. The backside of the cable gland should be filled with epoxy or sealant to prevent water ingress. Alternatively, NexSens can supply a waterproof bulkhead connector with mating pigtail for splicing with user-supplied sensor cables. This allows for a quick disconnect of the cable at the lid.

When using an X2-CB or X2-CBMC data logger on a NexSens integrated system, all supplied sensor cables are terminated with mating UW plug connectors or MCIL-8-FS connectors.

How do I mount a Doppler current profiler to the data buoy?

The mounting for an acoustic Doppler current profiler (ADCP) is instrument-dependent. NexSens offers several ADCP mounts for Nortek instruments, including the Aquadopp and Signature Series ADCPs. The mounts must be designed in such a way that the acoustic beams are unobstructed by the buoy and mooring. Custom mounts are also available based on project-specific needs.

Birds, Fish and Shifting Sediment; How Lake Erie Buoys Measure It All

Since its population bottomed out, the federally-endangered Piping Plover in the Great Lakes has made a comeback for the ages.  A population that once measured approximately 17 pairs and rebounded, hitting 76 pairs in 2017. The same year that count was made, the plovers had also returned to Gull Point, a nesting location that hadn’t been used in more than 60 years.   In an effort to understand some of the conditions that have allowed this species to return to its habitat, researchers have directed their attention toward a curious instrument for help. A buoy that floats off the coast of Presque Isle State Park , near where Gull Point is located.

Cellular Data Buoy Supports Lake Erie Algae Research, Public Outreach

Scientists at Ohio State University are at the fore of the fight against harmful algal blooms in Lake Erie. In fact, they deployed a new cellular data buoy off the shore of Gibraltar Island in 2014, months before the Toledo Water Crisis spurred a boom in monitoring platforms around the lake. That was in part because researchers at the university’s Stone Laboratory, backed by Ohio Sea Grant and housed on Gibraltar, had been seeing a resurgence of blooms in the lake long before international attention came around following the crisis. There was an opportunity, they saw, to continue advancing the mission of research, education and outreach on Lake Erie. The cellular data buoy complimented that in a great way.

Buoy Data Gauge Liberty Island Restoration Project’s Progress

The Liberty Island Restoration Project was an ambitious undertaking to bring back part of the California Delta’s wetlands and habitat. The damage to the wetlands that were once present there had persisted for so long that officials working on the project had to bring in historians just to figure out where the old marshes used to be. That was around 2010, during which year a design for the project was completed and implemented. It created open water channels, emergent tidal marsh lands and floodplain habitats to sustain water fluctuations. All of this was done in an effort to help important wildlife living in the delta as well as fish species like Chinook salmon and delta smelt.
