A monitoring initiative named for Secchi disks encourages people across the world to test the water nearby from the end of June through mid-July.
It’s called the Secchi Dip-in and its organizers want anyone with the means to test their local water to do so and report back. The database is open to contributions from June 29 through July 21.
Volunteers, monitoring groups and professionals alike can contribute data to the Secchi Dip-in database. Turbidity data is the main information Secchi Dip-in organizers want to see, but they won’t turn down any kind of water quality data people contribute.
They encourage interested environmentalists to go out with someone who is experienced in testing for water quality to ensure data is accurate.Read More
For most humans, mayflies seem like a nuisance, hovering over the waterways as we try to enjoy them. However, for anyone hoping to monitor the health of watersheds, mayflies are important aquatic species—and now, a digital version of the mayfly is helping some scientists keep an eye on the water. Research scientist Dr. Scott Ensign , who serves as Assistant Director of the Stroud Water Research Center , spoke to EM about how the digital mayfly technology developed.
“ Shannon Hicks is the engineer who started developing the Mayfly six or seven years ago,” explains Dr. Ensign.Read More
Time is of the essence when it comes to tracking algal blooms, and people everywhere are looking for solutions. In Florida, scientists from Florida Atlantic University Harbor Branch Oceanographic Institute (HBOI) recently trialed a solar-powered, algae-tracking sail boat developed by Navocean , Inc. Dr. Jordon Beckler of Florida Atlantic University (FAU) directs HBOI's Geochemistry and Geochemical Sensing Lab and spoke to EM about the trials and the boat.
"This boat is so amazing when you see it in action," remarks Dr. Beckler. "Navocean originally contacted me a few years back about a demonstration when I was over at my previous institution in West Florida, and we brainstormed some scenarios for employing the boat for harmful algae bloom monitoring.Read More
