The NexSens CB-1450 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 50" tall stainless steel tower includes three 55-watt 12VDC solar panels, and a center 12" ID x 55" tall data 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-1450 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.

NexSens CB-Series data buoys offers lineup from compact to powerful

The 2014 line of CB-Series data buoys combines traditional NexSens Technology reliability with a number of new innovations designed to handle real-time data collection applications in waters from the Great Lakes to the Arctic. Each of the four CB-Series data buoys comes equipped with at least three solar panels, pass-through holes for water sensor deployment and topside mounts for weather sensors. But the buoys’ most exciting enhancement is the addition of a spacious, cross-compatible instrument well that protects your delicate electronics “The biggest change is we now have a large data well that allows us to integrate batteries, data loggers and other electronics,” said Paul Nieberding, Fondriest Environmental general manager.

Real-time phosphorous sensor measurements tested on new Lake Erie data buoy

Two new experimental data buoys bobbing on Lake Erie are giving scientists a chance to test new instruments while sharpening their watch over Lake Erie in harmful algal bloom season. A crew from the National Oceanic and Atmospheric Administration’s Great Lakes Environmental Research Laboratory and the University of Michigan deployed the buoys in western Lake Erie in the first week of June One will test a wind sensor that's new to the lab. The other will for the first time relay up-to-the-hour measurements of phosphorus levels back to the lab in Ann Arbor, Mich.

Ice Fishing With A SondeCAM Underwater Fishing Camera

Thinking of hitting the ice with a SondeCAM underwater fishing camera? Due to its rugged design, you won't have to worry about it handling the harsh elements. However there are a few simple tricks to get the most out of a FishSens SondeCAM while ice fishing. You won't have to do anything to modify the SondeCAM itself, but you are going to have to bring a few extra things. Most importantly we are going to need a power source. Unless you are hauling your gear with a truck, you'll want something more portable than the battery you used in the boat. Pick up an inexpensive and maintenance-free 12-volt, 9-amp battery. It is going to provide plenty of power, but will be much lighter and take up less space.
