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.

Watchful Eyes on One of Maine's Crown Jewels: Jordan Pond
Formed by a glacier, Jordan Pond is among Maine's clearest, most beautiful bodies of water. It's also a critical freshwater resource, and watchful eyes are protecting it. EM spoke with Dr. Rachel Fowler, Friends of Acadia's aquatic scientist, about her work monitoring Jordan Pond. A postdoctoral research scientist at the University of Maine, she is a member of a partnership among the National Park Service, the University of Maine Climate Change Institute, and Friends of Acadia that began deploying the Jordan Pond buoy in 2013. Canon provided the initial support for the project. Friends of Acadia is a nonprofit organization that supports different projects in the park.

Algae Bloom Spawns New Water Monitoring Program In Utah Lake
The result of a harmful algae bloom in the summer of 2016, the enhanced Utah Lake water quality monitoring program reached its one year milestone in September. Located near the Provo and Orem metropolitan areas, the lake is Utah’s largest freshwater body and a popular water recreation and fishing spot. In the summer of 2016, recreation users reported an unusual amount of scum on the surface of the water. Utah Lake is monitored by the Utah Division of Water Quality (UDWQ). Prior to the 2016 harmful algae bloom (HAB), the UDWQ successfully used regular water sample testing and citizen reporting to stay on top of any incidents.

Data Buoys Study Turbid Water Environments In Lake Erie Basin
What started as a study into a relatively unexamined type of cyanobacteria has turned biologists from Bowling Green State University into an integral part of the effort to monitor and protect the drinking water in Sandusky, Ohio. Dr. George Bullerjahn, the Professor of Research Excellence at Bowling Green State University, has done considerable work in the study of beneficial cyanobacterial organisms in the eastern and central basins of Lake Erie. His current project is focused on the growth of the toxic cyanobacterium Planktothrix in Sandusky Bay. Over the course of his career Bullerjahn has collaborated with Dr. Steven Wilhelm from the University of Tennessee.
