Questions & Answers

| Ask a Question
My DO% samples read low and then high to low, is this a bad reading?
The initial power up can make the first two DO% readings read low. These readings can be disregarded.
My sonde is reading a negative value for turbidity, did I calibrate incorrectly?
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.

Lake Superior Weather Buoy Provides Valuable New Data

A new weather buoy in a remote part of Lake Superior is providing much-needed weather data to local mariners, the National Weather Service and researchers. Scientists from the Superior Watershed Partnership (SWP), Lentic Environmental Services (LES) and the University of Colorado-Boulder recently deployed the buoy on the lake one mile north of Stannard Rock Lighthouse. SWP gained ownership of the lighthouse in 2015. Because the light was built on a large reef in a remote part of the lake, it is one of the most popular trout fishing and charter boat destinations on the Great Lakes. It has also been the location of a NOAA weather station since 1984 and a Great Lakes Evaporation Network monitoring site since 2008.

Nonprofit kick-starts water data gathering in Nepal Valley

For the first time, citizens of the Kathmandu Valley in Nepal have free access to local water data. The data is the result of a water quality monitoring pilot project started by the California-based nonprofit SmartPhones4Water (S4W). SmartPhones4Water, an idea developed by Ph.D. student Jeff Davids and the late Dr. Peter-Jules van Overloop from Delft University of Technology (Netherlands), was started in California in 2014. The goal of the organization is to leverage smartphone technology to gather water data in countries where such data is scarce. The method is simple: a network of local citizens use their smartphones to capture and upload the data to an online server and database.

Riverkeeper Initiative Tackles Water Monitoring, Activism and Education

Celebrating its 25th year, Coosa River Basin Initiative is forming a new water monitoring partnership with the Berry College Environmental Science program. Coosa River Basin Initiative, also known as CRBI , is a grassroots environmental protection organization that works with volunteers to protect and preserve the Coosa River in Rome, Georgia and the surrounding cities. CRBI is a member of the Georgia Water Coalition and the Waterkeeper Alliance. You may be wondering what is so special about the Coosa River. The answer is just about everything. The river is a vital part of the communities surrounding it. “Every river is important but the Coosa River is important in several unique ways,” said Jesse Demonbruen-Chapman, director of CRBI.
