The NexSens CB-450 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 20” tall stainless steel tower includes three 13-watt 12VDC semi-flexible solar panels, and a center 10” ID x 19.5” tall instrument 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-450 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: 34” (86.36cm) outside diameter; 20” (50.80cm) tall
  • Tower Dimensions: 20” (50.80cm) tall, triangular
  • Data Well Dimensions: 10.3” (26.16cm) inside diameter; 19.5” (49.53cm) tall
  • Weight: 145 lbs. (65.77 kg)
  • Buoyancy: 450 lbs. (204.12 kg)
  • Hull Material: Cross-linked polyethylene foam with polyurea coating & stainless steel deck
  • Hardware Material: 316 stainless steel
  • Mooring Attachments: 1 or 2 point, 3/4” eyenut
  • Solar Power: (3) 13-watt 12 VDC solar panels
Questions & Answers
Are the buoys safe for coastal deployment?

While we generally recommend the CB-650 and larger data buoys in coastal environments, we do have many customers that have successfully deployed the CB-450 in coastal environments.

Can this model be deployed for long periods of time?

Yes, the CB-450 is designed for seasonal or year-round deployment. The system offers autonomous power with integrated battery harness and solar charging.

Can data be retrieved offshore?

When integrated with the X2-CB data logger with Wi-Fi, cellular, Iridium satellite, or radio telemetry, data is accessible in real-time via the WQData LIVE secure web datacenter.

While deployed, can the buoy be wirelessly troubleshooted?

When integrated with a wireless modem or X2-CB buoy-mounted data logger with wireless communications, the system can be accessed for remote configuration and/or troubleshooting.

How can I ensure buoy stability?

Buoy stability is dependent on a number of factors including instruments attached, mooring design, water currents, and regional weather conditions. It is recommended to examine the buoy upon deployment, adding ballast weight and adjusting the mooring as needed. Given that each deployment is unique, be sure to communicate with NexSens application engineers for optimal stability.

Under what conditions would I need to remove the CB-450 data buoy?

Freezing and periodic maintenance are the two most common reasons to remove a buoy from the water. A large number of buoy deployments are seasonal, so customers will commonly remove the buoy in the fall and redeploy in the spring. For year-round buoy deployments, NexSens recommends pulling the buoy at least once for cleaning and maintenance inspection.

The potential for large storms and river debris flows are also good reasons to pull a buoy in order to prevent any ensuing damage. NexSens recommends integrating a GPS in situations where debris loads or other circumstances have the potential to move the buoy, like in a river or coastal setting.

How do I know if I need an anti-rotation collar on the instrument cage?

An anti-rotation collar is not necessary if the buoy is deployed on two point mooring and no instruments are attached to cage. Anti-rotation collars are recommended for single point moorings or when instruments are attached to the cage. This provides an added strength member and prevents the potential for cable tangling.

Watchful Eyes on One of Maine's Crown Jewels: Jordan Pond

Formed by a glacier, Jordan Pond is among Maine's clearest, most beautiful bodies of water. It's also a critical freshwater resource, and watchful eyes are protecting it. EM spoke with Dr. Rachel Fowler, Friends of Acadia's aquatic scientist, about her work monitoring Jordan Pond. A postdoctoral research scientist at the University of Maine, she is a member of a partnership among the National Park Service, the University of Maine Climate Change Institute, and Friends of Acadia that began deploying the Jordan Pond buoy in 2013. Canon provided the initial support for the project. Friends of Acadia is a nonprofit organization that supports different projects in the park.

Algae Bloom Spawns New Water Monitoring Program In Utah Lake

The result of a harmful algae bloom in the summer of 2016, the enhanced Utah Lake water quality monitoring program reached its one year milestone in September. Located near the Provo and Orem metropolitan areas, the lake is Utah’s largest freshwater body and a popular water recreation and fishing spot. In the summer of 2016, recreation users reported an unusual amount of scum on the surface of the water. Utah Lake is monitored by the Utah Division of Water Quality (UDWQ). Prior to the 2016 harmful algae bloom (HAB), the UDWQ successfully used regular water sample testing and citizen reporting to stay on top of any incidents.

Data Buoys Study Turbid Water Environments In Lake Erie Basin

What started as a study into a relatively unexamined type of cyanobacteria has turned biologists from Bowling Green State University into an integral part of the effort to monitor and protect the drinking water in Sandusky, Ohio. Dr. George Bullerjahn, the Professor of Research Excellence at Bowling Green State University, has done considerable work in the study of beneficial cyanobacterial organisms in the eastern and central basins of Lake Erie. His current project is focused on the growth of the toxic cyanobacterium Planktothrix in Sandusky Bay. Over the course of his career Bullerjahn has collaborated with Dr. Steven Wilhelm from the University of Tennessee.
