The initial power up can make the first two DO% readings read low. These readings can be disregarded.
A sonde (even if cleaned properly) can contaminate to almost 1.0 NTU. Typically the average contaminant level ranges from 0.2 to 0.8 NTU. With this knowledge, you can enter this offset (0.5 NTU) using the sonde's One-Point Calibration feature. This calibration is only done after a two- or three- point calibration is completed. To do a One-Point Calibration after a two- or three- point calibration: Place the sonde in a container of zero standard or filtered DI water. Use of the supplied calibration/storage cup is recommended; however, any generic glass or plastic container can be used as long as the probe guard is installed. Enter the Turbidity offset as 0.5 NTU, operate the wiper and inspect for air bubbles. Wait at least 60 seconds after the last wiper to accept the calibration point.

It’s an open, dirty secret that the ocean is used as the ultimate sewage solution.
Each year trillions of gallons of untreated waste are sent to the ocean due to a widespread lack of sanitation technology or infrastructure that needs updating as cities and populations grow. As the impact of untreated sewage on the ocean becomes clearer, attention to the problem and strategies for dealing with it have not kept up.
“This is a massive problem and it’s been largely ignored,” said Stephanie Wear, senior scientist and strategy advisor for The Nature Conservancy. Wear has turned her attention to raising the alarm about the effects of sewage on coral reefs, which often loses airtime to other pressing issues like climate change and overfishing.Read More
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.Read More
*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.Read More
