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.

Lake Superior Algal Blooms Surprise, Highlight Need for More Monitoring

In 2012, for maybe the first time, Lake Superior got scummy. Visitors to the Apostle Islands National Lakeshore reported algae washing up on shore around the park.  It was a marked shift for the park, made up of a portion of the Lake Superior lakeshore and nearby islands. The water surrounding the park is cold, clear and typically low in nutrients: a combination unlikely to result in algal blooms. But, in 2012 and again in 2018 after violent storms, major algal blooms—ones observed over multiple days—washed ashore and clogged the beaches with unsightly, scummy algae. Not the usual suspects The algal blooms of Lake Superior are not the algal blooms of warmer, more nutrient-rich lakes like Lake Erie.

Unprecedented Changes are a New Challenge for Lake Tanganyika

*This is part two of a series on changing ancient lakes. See part one, Lake Baikal, here . Ancient lakes are facing a suite of rapid, unprecedented anthropogenic changes. While ancient lakes are spread around the world and vary widely from lake to lake, their incredible age, which can reach into the tens of millions of years, makes them unique resources to science. They host incredible biodiversity and long sediment records. They are vital sources of food and water for millions of people. In a changing world, ancient lakes’ value as scientific and natural resources and the incredibly diverse life they contain is under threat.

After Millions of Years, Ancient Lakes Face New Challenges

*This is part one of a two part story on ancient lakes. Part two , Lake Tanganyika, available here. Lakes that have supported human settlements for thousands of years are starting to feel humans’ effects in rapidly developing and significant ways. From climate change to nutrient loading to plastic pollution, ancient lakes are straining under some of the least welcome contributions of humanity. The changes could have consequences for the diversity of life within the lakes and the human populations that rely on it. And, while ancient lakes have been around long enough to weather past climatic changes, the changes occurring now are so rapid, the end result is uncertain.
