Dock Monitoring System

Pre-existing structures such as docks, piers and bridge pilings are great locations for the deployment of a long-term water quality, hydrology, and/or weather monitoring system. Mounting to secure structures cuts down expenses and allows for better accessibility.

NexSens data loggers support a variety of these sensors collecting real-time data on user-defined parameters. Deployment pipes house and protect water quality sondes and level sensors while still making them accessible for maintenance and calibration. On the receiving end, WQData LIVE offers a convenient and secure location for accessing and disseminating data.

NexSens

The MAST is designed for quick deployment of remote data logging and telemetry systems. The X2 data logger and solar panel/battery pack can all be mounted to the MAST prior to deployment. By pre-assembling the components, the system can be quickly deployed in the field.

Airmar 200WX Ultrasonic WeatherStation Instrument

The Airmar 200WX is a compact weather station ideal for moving platforms. The sensor outputs apparent and true wind speed and direction, barometric pressure, air temperature, GPS location, and more.

NexSens SP-Series Solar Power Packs

The SP-Series Solar Power Packs feature a solar panel, regulator, and battery housed in a weather tight enclosure. Solar Power Packs are used to provide continuous power for X2 and V2 systems. All components are weather tight and designed to withstand harsh conditions.

NexSens X2 Environmental Data Loggers

The X2 is an all-in-one environmental data logger with a large plug-and-play sensor library and ultra-low power consumption that can be controlled from any internet browser using a smartphone, tablet, or PC. It automatically recognizes sensors and sends data to the web via Wi-Fi, cellular, radio, or satellite telemetry.

NexSens Sonde Deployment Pipe

PVC or metal deployment pipes are installed to protect the dissolved oxygen sensors in the water. The pipe is perforated near the sensor to allow adequate water flow for a representative measurement. In addition to shielding the sensors from debris, the pipe helps secure the equipment in a fixed position for quality data and offers easy removal for calibration.

YSI EXO3 Multi-Parameter Water Quality Sonde

YSI EXO3 is a purpose-built sonde for monitoring major water quality parameters, including pH, conductivity, temperature, dissolved oxygen, ORP, TAL-chlorophyll, phycocyanin or phycoerythrin and turbidity.

Chesapeake Bay Best Management Practices

Because of the roles that shallow areas play in supporting the health of Chesapeake Bay, including serving as productive regions full of grass beds and nursery grounds for juvenile fish, managers with the Maryland Department of Natural Resources (DNR) are understandably interested in keeping tabs on how their conditions change over time. It’s possible to assess some of those by going out at a set interval (daily, weekly, monthly) and gathering water samples to analyze. But such a scheduled approach wouldn’t give managers the around-the-clock data that they really need to get a complete picture of what’s going on in the shallows over time.

Buck Creek Dam Removal & Restoration

Located in southwest Ohio, Buck Creek and its tributary, Beaver Creek, run through a series of low-head dams in the city of Springfield. Historically, the four dams diverted water for mills and local industry and protected utilities along a continuous four-mile reach. However, they’ve also interfered with the water’s natural flow and inhibited stream health. The Springfield Conservancy District and Friends of the Buck Creek Recreation Corridor are working to restore a more natural flow to the creek while maintaining the benefits provided by the dams. Though planned changes to the dams are primarily for recreational purposes, they will help restore the flow of sediments and fish, as well as provide a healthier ecosystem for Buck Creek. Approved by the U.S. Army Corps of Engineers, removal of one of the low-head dams and modification of another began in the fall of 2009.

River Water Quality and Automated Sampling System

Located within the quickly developing area of northern Columbus and southern Delaware County, the Olentangy River is a tributary of the Scioto River in Ohio. Despite rapid housing and business development around the Columbus area, the Olentangy River has seen an improvement in water quality, as it was upgraded to an exceptional warm water habitat by the Ohio Environmental Protection Agency. Recently, Ohio State University’s Wilma H. Schiermeier Olentangy River Wetland Research Park contacted NexSens Technology to install a water quality monitoring station with radio telemetry in the Olentangy River.
