Emergency Response Buoy

Construction projects, dredging operations and emergency response situations call for a platform that can monitor water quality at a moment’s notice, while alerting project managers of exceedances and potential concerns.

The CB-50 is easily deployable by one person and can decrease response times when it matters most. Once the system hits the water, data can be managed and interpreted from the WQData LIVE cloud-based datacenter.

NexSens M550 1-3NM Solar Marine Light

NexSens M550 solar marine lights are designed for mounting to the CB-Series data buoys per USCG requirements.

CB-50 Data Buoy

The CB-50 data buoy is an ultra-portable real-time system for short-term or seasonal monitoring of dredging projects, industrial spills, natural disasters, and other emergency response situations.

X2-SDL Submersible Data Logger

The X2-SDL Submersible Data Logger is a rugged, self-powered data logging and telemetry system for deploying environmental sensors in or near water without fear of accidental flooding.

NexSens EXO Sonde Mooring Cages

The NexSens EXO Sonde Mooring Cages provide a secure and convenient means of deploying a YSI EXO multi-parameter water quality sonde.

NexSens Buoy Cage Anti-Rotation Collar

The CB-CCA cage anti-rotation collar securely connects an instrument cage to the frame of a CB-Series data buoy system and prevents rotation or loosening of the cage.

YSI EXO2 Multi-Parameter Water Quality Sonde

The YSI EXO represents the next generation of water quality instruments from YSI. The EXO2 sonde includes six sensor ports and a central anti-fouling wiper option.

NexSens Stainless Steel Swivels

Stainless steel bow shackles securely connect mooring chain and custom-built SS mooring lines to NexSens data buoys and pyramid anchors.

NexSens Galvanized Chain

Galvanized chain is used to construct mooring lines for buoy-based water quality applications requiring single or multi-point moorings.

NexSens Pyramid Anchors

For excellent holding power, cast iron or steel mooring anchors such as these pyramids are far superior to granite or concrete blocks.

Case Studies


Protecting Ohio River Wildlife

A complex series of locks and dams up and down the Ohio River enable interstate commerce, travel, and recreation. But maintaining a usable pathway for watercraft comes at a cost. The inevitable byproducts of disrupting the river’s natural systems are a threat to local wildlife. To combat this, the US Army Corps of Engineers (USACE) uses complex monitoring and response technology designed to minimize the negative impacts of dredging on the river ecosystem.

Monitoring Toledo’s Water Crisis

The City of Toledo had been working for some time with LimnoTech, a water engineering firm based in Ann Arbor, Michigan, to design and deploy a monitoring platform for tracking conditions near the city’s water intake on Lake Erie. But after the Toledo water crisis of 2014, which saw half a million people deprived of water for consumption and bathing because of high levels of algae-produced toxins, the city put the project on the fast track.

New Bedford Harbor Superfund Site Dredging

New Bedford Harbor is fed by the Acushnet River from the north and drains into the Atlantic Ocean to the south. Its steady flow is one of the reasons so many industrial plants set up shop along the harbor in the early 1900s. Back in those days, no one knew about polychlorinated biphenyls, or PCBs, and their effects on the environment. So, along with utilizing the harbor’s water to operate their machinery, plants also used it as a destination for PCB-laden discharges that still affect the area today.
