NexSens CB-50 Data Buoy

The CB-50 Data Buoy is designed for quick deployment in emergency response situations including industrial spills and natural disasters. The buoy can be deployed from small boats, large vessels or even helicopters, making it the ideal choice for applications where water needs to be monitored at a moment’s notice. Compatible instruments include turbidity sensors, dissolved oxygen sensors, hydrocarbon sensors, fluorometers, multi-parameter sondes, pressure transducers, and more.

The buoy is constructed of an inner core of cross-linked polyethylene foam with a tough polyurea skin and stainless steel frame. The 5.5" ID center hole houses the X2-SDL data logging system, which includes integrated power supply and wireless antenna. A removable topside foam tower protects the electronics, supports solar marine lights, and offers a convenient lifting point via (3) 5/8" eyenuts. Optional accessories include instrument cages and mounting clamps to secure instruments to the platform.

The CB-50 Data Buoy is designed to accommodate NexSens X2-SDL submersible data loggers. Wireless telemetry options include cellular, Iridium satellite, and spread spectrum radio. The X2-SDL is configured with three sensor ports for connection to industry-standard digital interfaces including RS-485, RS-232 and SDI-12. Additional sensor inputs are available through the use of adapters. All sensor connections feature a double O-ring seal for a reliable waterproof connection.

Questions & Answers
What mooring equipment is needed for use with a multiparameter sonde?
An instrument CAGE with CM-600 cage mount clamp is recommended to secure the sonde below the buoy. For YSI EXO water quality sondes, a CAGE-EXO sonde mooring cage is available with custom clamps sized specifically for these instruments. In both instances, a CB-CCA anti-rotation collar is also recommended to keep the cage from rotating.
How is the system powered?
The CB-50 is designed for use with the X2-SDL submersible data loggers, which are powered by 16 user-replaceable D-cell alkaline batteries.
How is data obtained from sensors deployed on this platform?
Data is typically sent wirelessly to the WQData LIVE web datacenter via Wi-Fi, cellular, or Iridium satellite telemetry. For standalone applications, data can be manually offloaded to a Windows PC with a USB cable and CONNECT Software.
Can sensor strings be deployed from this platform?
Yes, temperature, dissolved oxygen, and other sensor strings can be deployed from this buoy. The CB-50 buoy platform is designed for single point moorings, so the CB-150 data buoy or larger platform is recommended when a 2-point mooring is needed.
Why is the CB-50 buoy best suited for short-term applications?
The CB-50 is light enough to ship in a box rather than on a pallet, which significantly reduces freight costs. It also deploys easily, as no large boat or crew is necessary. Once deployed, relocating the system is as easy as lifting the anchor, moving to the appropriate location, and dropping the anchor. Instead of using solar charging, the CB-50 buoy supports the X2-SDL Submersible Data Logger that is powered by sixteen user-replaceable D-cell alkaline batteries. When outfitted with wireless telemetry, the data logger transmits battery voltage as a diagnostic parameter to take the guesswork out of battery replacement frequcency (typically necessary every several months). The integrated X2-SDL submersible data logger is compatible with most water sensors on the market, making it a very flexible platform for short-term, portable, and even seasonal projects.
What important considerations are necessary for ballast weight?
An instrument cage is an optional addition to the CB-50 buoy. No extra weight is needed if the system includes any instrument cage model (CAGE, CAGE-EXO, etc.). If the system does not include an instrument cage, at least 20-25 pounds of extra weight should be added to the buoy frame. NexSens offers an optional 25 lb. ballast weight (PN# BAL25) that can be integrated between the buoy frame and mooring eye.
Can I integrate my own electronics on this platform?
While the CB-50 is designed for use with the X2-SDL Submersible Data Logger, the buoy has a 5.5" diameter hole in the center of the hull for user-integrated waterproof hardware. Upon request, NexSens can offer a size-compatible empty waterproof canister for integrating third-party electronics.

IoT for Smarter Aquaculture

With aquaculture booming, IoT may be the future of the market. Fish have been farmed for millennia but only recently has the industry achieved such a vast scale. As overexploitation and climate change threaten wild fish stocks, aquaculture is increasingly framed as an alternative that can provide a low-carbon, healthy protein source. But, as the global population grows, the industry has the monumental task of meeting the increasing demand for seafood. In order to provide higher yields economically and sustainably, it is turning to the Internet of Things, or IoT. IoT refers to technology that pulls data from smart sensors to the Cloud and crunches it using analytic software tools, including artificial intelligence (AI), to monitor and improve efficiency or productivity.

Low Tech, Low Cost Buoys Coming to Maine’s Shellfish Farmers

What might the Maine Aquaculture Innovation Center’ s (MAIC) buoy offer that other governments and university monitoring equipment lack? The center doesn’t have MicroCAT recorders or autonomous acoustic sensing gliders. It’s not deploying hundred-thousand-dollar oceanographic mooring lines gathering massive amounts of data. So what can MAIC’s three-foot prototype buoy offer that others can’t? It’s easy to clean and costs very little. “One of the big issues for putting anything in the water is biofouling,” said Josh Girgis, an engineer at MAIC based at the University of Maine’s Darling Marine Center (DMC). “If you put a sensor in, you can only expect it to work until something starts growing on it.

Combating Water Insecurity in Saskatchewan with Real-Time Data

The prairies of Saskatchewan can be described as one of the least water-secure parts of Canada, making water quality monitoring essential for informed resource management in a region already facing water insecurity. While natural physical properties worsen some of the poor water quality conditions in the region, others are connected to land use. Having grown up spending summers on the shores of Lake Huron, Helen Baulch, an associate professor at the School of Environment and Sustainability at the University of Saskatchewan , has always been dedicated to the protection of water resources. Looking back fondly at her childhood playing along the shore, Baulch also recalls the invasion of quagga mussels during her teenage years and watching the lake change as a result.
