The NexSens CB-650 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 40” tall stainless steel tower includes three 30-watt 12VDC unbreakable solar panels, and a center 10” ID x 21.5” tall data well accommodates batteries, data loggers, sensors, and more. Three 4” 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-650 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: 38" (96.52cm) outside diameter; 22" (55.88cm) tall
  • Tower Dimensions: 40” (101.60cm) tall, 7/8 tubular
  • Data Well Dimensions: 10.3” (26.16cm) inside diameter; 21.5” (54.61cm) tall
  • Weight: 215 lbs. (97.52 kg)
  • Buoyancy: 650 lbs. (294.84 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) 30-watt 12 VDC solar panels
Questions & Answers
How are these buoys protected from impact by moving vessels in the open ocean?

An optional CB-RR radar reflector is available to make these buoys visible on radar screens.

Once deployed, are instruments accessible without pulling in the equipment?

Yes, there are 4" instrument holes with female NPT pipe threads that can secure a deployment pipe for multi-parameter sondes and other sensors to be accessed from the top of the buoy hull.

Can I use my own electronics on this platform?

Yes, the CB-150 and larger data buoys include a 10” diameter watertight data well for user-supplied electronics and batteries. The included pass-through data well lid includes gland fittings for running cables and providing a tight seal.

Can these buoys be deployed in saltwater applications?

Yes, the optional CB-ZA sacrificial zinc anode is recommended to be attached to both the buoy frame and instrument cage to mitigate corrosion in saltwater environments. All metal on the buoy is constructed with Type 316 Stainless Steel for optimal corrosion-resistance.

Do I need sacrificial anodes in any saltwater application?

Sacrificial zinc anodes are recommended for any buoy deployed in saltwater or brackish conditions. Sacrificial anodes prolong the life of the buoy and protect the stainless steel hardware and instrument cage from corrosion. Both the buoy frame and the instrument cage should have a sacrificial anode attached (2 per buoy). Check the anodes during each maintenance visit and replace when necessary, which is typically six months to one year depending on conditions.

Why is it called the CB-650 data buoy and why is it yellow?

CB stands for "Coastal Buoy". The number 650 denotes net buoyancy, the buoyant capacity of the buoy after hardware is installed. A safety yellow hull is a standard international practice and requirement of the U.S. Coast Guard to signify research buoys.

What applications require a radar reflector?

Radar reflectors are important in high traffic waterways to alert boats and vessels. While the lid on top of the hull has some radar reflecting qualities, adding a radar reflector will ensure radar visibility at any time. It is recommended for any offshore buoy to be fitted with a radar reflector and navigation light.

What is the difference between the CB-650, -950 and -1250?

In addition to buoyancy capability, the solar towers offer incrementally larger solar panels for projects with a heavier power load. The bigger the buoy, the more batteries can be stored in the data well for reserve power. The instrument hole diameters are 4 inches, 6 inches and 8 inches respectively in the three large buoy models.

Scientists Play the Long Game at Wisconsin’s Trout Lake Research Station

Summer’s effects on the ecology and hydrology within Wisconsin’s inland lakes are well studied. Data collection is easier and many field-deployed sensors and equipment can withstand the conditions of a Midwestern heat in July. But what about changes in the winter? The historic assumption is that not a lot happens. Frozen conditions on the lake’s surface render the normally shifting environment underneath quiet and undisturbed. However, researchers at the University of Wisconsin Madison Center for Limnology are discovering that’s not exactly true. “It’s often difficult to sample, especially during bookends when ice is just freezing or when ice is thawing in the spring. It’s just not safe to get out there,” said Noah Lottig.

Tsunami's Effects Lasting Years for Marine Creatures

Adrift on the open ocean, even aquatic species can feel stranded, without their usual habitats and food sources. This has been the situation for various species post-201 1 Japanese tsunami   for years now. Researchers are digging into the lasting effects this displacement could have on them—and on the places they end up. Dr. Linsey Haram , a postdoctoral fellow at the Smithsonian Environmental Research Center (SERC) , spoke to EM about her research following the winding path of some of these species. "I wasn't directly involved with the tsunami debris work because I hadn't started working at the Smithsonian," explains Dr. Haram.

Lake Superior Algal Blooms Surprise, Highlight Need for More Monitoring

In 2012, for maybe the first time, Lake Superior got scummy. Visitors to the Apostle Islands National Lakeshore reported algae washing up on shore around the park.  It was a marked shift for the park, made up of a portion of the Lake Superior lakeshore and nearby islands. The water surrounding the park is cold, clear and typically low in nutrients: a combination unlikely to result in algal blooms. But, in 2012 and again in 2018 after violent storms, major algal blooms—ones observed over multiple days—washed ashore and clogged the beaches with unsightly, scummy algae. Not the usual suspects The algal blooms of Lake Superior are not the algal blooms of warmer, more nutrient-rich lakes like Lake Erie.
