The NexSens CB-250 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 2” 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-250 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.

Questions & Answers
Can the solar panels be individually replaced in the field?

The solar panels feature a waterproof 2-pin connector that plugs into a 3-way splitter on the solar tower. In the event of a failure, the solar panel can be swapped out in the field.

Monitoring Buoy Supports Nautical Archaeology

For as long as humans have inhabited Europe’s Atlantic coast, the ocean has been a great source of wonder and mystery. History is full of fascinating tales of epic endeavors, new discoveries of fearless explorers, fishing communities inextricably linked to the bounties of the sea, cultural interactions both peaceful and not, and voyages that went awry during monumental storms or simply due to bad luck. In the south of Spain, at the boundary between the Atlantic Ocean and the Mediterranean Sea, one such tale involves a long-lost merchant ship that went undiscovered from the 16th century until 1984. Believed to be carrying valuable goods from Italy, it sank just across from Gibraltar in the Algeciras Bay at a point called La Ballenera.

Staying Within Budget: Carbon Planning

While we usually concern ourselves with budgeting money or time, we should be thinking about another type of budget: the carbon budget. The carbon budget refers to the amount of carbon exchange, especially carbon dioxide, allotted on an annual basis to prevent the earth from reaching an increase of 2-degrees Celsius all over the globe. If a 2 degree increase does occur, global warming effects are expected to be catastrophic and irreversible. In order to know how close we are to reaching the carbon budget, an extensive knowledge of types of carbon input and their magnitudes, as well as their fluctuations over time, is needed.

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.
