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 15-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 X2-CB data loggers. Wireless telemetry options include cellular, Iridium satellite, and spread spectrum radio. Compatible digital sensor interfaces include RS-232, RS-485 and SDI-12. Each sensor port offers a UW receptacle connector with double O-ring seal for a reliable waterproof connection. For custom integrations, an optional pass through data well lid includes a set of plugs and cable gland fittings.

Floating Global New Ideas: Buoy-Enabled Research at Florida Agricultural and Mechanical University’s School of the Environment
Florida Agricultural and Mechanical University (FAMU), based in Tallahassee, Florida, is the highest-rated public Historically Black College or University in the United States. FAMU’s School of the Environment (FAMU-SOE) offers BS and BA degrees in Environmental Studies, and BS, MS, and Ph.D. degrees in Environmental Science, with specialisms available in areas including Environmental Policy and Risk Management, Aquatic and Terrestrial Ecology, and Biomolecular Sciences. 
 
 In 2021, FAMU-SOE deployed a NexSens CB-450 buoy in Apalachee Bay, a key oyster farming area around 30 miles south of Tallahassee. The buoy has quickly been incorporated into the curriculum, providing environmental insights for student research, the community, and beyond.

Lakes everywhere are threatened by climate change, harmful algal blooms , invasive species, and other environmental stressors. Local, regional, and federal agencies have stepped up in order to defend the environment and water resources. The Lakes Environmental Association (LEA) in Maine is one example of an organization dedicated to protecting local freshwater resources. 
 
Dr. Ben Peierls, LEA Research Director, explains the history of the nonprofit, "For more than 50 years, [LEA] has been working locally, statewide, and regionally, helping or interacting with people on lake water quality, watershed protection, conservation, education, invasive species, and other issues.

Most people go to Lake Champlain for its exceptional views and thrilling boating, but it’s also home to a wide variety of interesting aquatic research projects. From studying microplastics to thermal dynamics of the lake, Timothy Mihuc, director of the Lake Champlain Research Institute (LCRI) at the State University of New York at Plattsburgh (SUNY Plattsburgh), has spent his career studying aquatic ecosystems. 
 
 As an aquatic biologist, he’s the main investigator on Lake Champlain’s research studies while also managing their grants, employees, and their hands-on buoy work. 
 
 Over the years, LCRI has received a number of environmental grants that aid in its monitoring research.
