The NexSens G2-ISI Water Level & Quality Monitor is specifically designed to interface with In-Situ Level TROLL, Aqua TROLL, and RDO sensors. It has an integrated data logger and cellular modem to provide real-time connectivity to the instrument’s readings. This uniquely simple solution allows existing monitoring locations to add real-time data with minimal effort at a fraction of the cost compared to other data logger solutions.

G2-ISI can be configured directly from any web browser without the need for costly site visits and complicated connections. The system wirelessly transmits water quality data to WQData LIVE’s cloud-based data management platform at user-defined intervals. Paired with WQData LIVE’s configurable alerts, users can be automatically notified of data outliers or other anomalies directly on a mobile device or computer. Historical data can be viewed, graphed, and downloaded from WQData LIVE for additional analysis.

Designed for simplicity, the G2-ISI includes an SP8 solar power pack to allow for long-term deployments without the need for frequent site visits and maintenance. The integrated cellular modem with bundled NexSens hosted service provides real-time communication without the complexities of setting up a cell account. A compact and integrated design with all parts pre-mounted to a 2” NPT pipe makes deployment simple.

Is eradicating Great Lakes sea lamprey an “impossible dream?” Researchers say no

The sea lamprey’s days in the Great Lakes could be numbered. That’s according to one researcher who took one of the first scientific looks at the possibility of sea lamprey eradication in the Great Lakes. So, can you remove enough sea lamprey to make them disappear? “Well the answer is we already have,” said Michael Jones, emeritus professor of fisheries and wildlife at Michigan State University. “Then there’s the obvious question: Why are they still here?”  While multiple gaps in current management techniques, like sea lamprey poisons called lampricides, could account for sea lamprey’s persistence in the Great Lakes, new technology could help sea lamprey managers eliminate inaccessible populations.

America’s Elusive Crayfish and the eDNA that’s Finding Them

The Shasta crayfish and signal crayfish are two similar looking arthropods on two very different ecological trajectories. As one spreads in abundance, originating in the Pacific Northwest and spreading throughout the world, the other has been reduced to a handful of remaining populations spread throughout one river and its tributaries.  Pacifastacus leniusculus - the signal crayfish - has met few obstacles in its widely successful expansion from the Pacific Northwest southward in California and Nevada, as well as Europe and Japan. By some expert accounts, it has reached invader status. And while invasive species are rarely good for the surrounding food webs, it’s Pacifastacus fortis - the Shasta crayfish - that’s suffered the most at the signal crayfish’s fortune.

Low Tech, Low Cost Buoys Coming to Maine’s Shellfish Farmers

What might the Maine Aquaculture Innovation Center’ s (MAIC) buoy offer that other governments and university monitoring equipment lack? The center doesn’t have MicroCAT recorders or autonomous acoustic sensing gliders. It’s not deploying hundred-thousand-dollar oceanographic mooring lines gathering massive amounts of data. So what can MAIC’s three-foot prototype buoy offer that others can’t? It’s easy to clean and costs very little. “One of the big issues for putting anything in the water is biofouling,” said Josh Girgis, an engineer at MAIC based at the University of Maine’s Darling Marine Center (DMC). “If you put a sensor in, you can only expect it to work until something starts growing on it.
