Super-Turbidity is a patent pending technology developed by Sequoia Scientific, Inc. It involves pairing a LISST-ABS with a turbidity sensor using a weight factor, which results in a single, combined output from the two sensors. Once paired, the LISST-AOBS retains near-constant calibration for SSC over a wide grain-size range. The LISST-AOBS Super-Turbidity sensor is supplied by Sequoia as an integrated and paired turbidity and acoustic sensor with a variety of cabling and data logger options.

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.

Biochar Adds Filtering Power to Biofilters

Contaminated stormwater threatens a lot of water in the United States. Nearly 50,000 miles of rivers, 760,000 acres of wetlands and one million acres of estuaries are threatened by contaminated stormwater, according to the US Environmental Protection Agency. Those numbers are cited in a review of research recently published in Environmental Science: Water Resource & Technology that looks at one tool for tackling that threat: biochar-augmented biofilters.
