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 41” tall stainless steel tower includes three 46-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 X3 data loggers. Wireless telemetry options include global 4G LTE cellular, Iridium satellite, and global 4G LTE cellular with Iridium satellite fallback. 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, CB-PTL pass through and CB-MCL wet-mate data well lids are available.

Buoy Camera Research: Key for Regional Science Consortium
Jeanette Schnars has been the Executive Director of the Regional Science Consortium, a cooperative research leader located on the shore of Lake Erie, for 15 years. In that time, she has overseen some major technological innovations, such as the increased use of buoy cameras. “We were actually one of the first research groups to use video monitoring on a buoy,” she recalls. The Regional Science Consortium (RSC) is a non-profit collective of researchers and educators that facilitates knowledge gathering and dissemination regarding the Lake Erie and Ohio River Basin ecosystems for K-12, member colleges, and the general public.

Diatoms Dominate Muskegon Lake In A Cold And Rainy Year
Climate change-driven volatility is changing lakes at the base of their food webs. That’s one way to interpret new research that documented such a change in Muskegon Lake on the coast of Lake Michigan. Researchers found that, in one particularly rainy and cool year, normal phytoplankton diversity and patterns were cast aside. Instead, one group of algae dominated the entire year, offering a glimpse into the kinds of surprising changes that could happen in the future. “Phytoplankton are a very responsive group of organisms,” said Jasmine Mancuso, whose research detailing the change in the lake was published in October in the Journal of Great Lakes Research .

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.
