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
Each year in Germany, as many as 450,000 living fish undergo live animal experiments to test how fish-friendly hydroelectric power plants in the country are. The idea is to discover how readily the fish can move through hydroelectric turbine installations in order to ultimately reduce mortality rates.
Of course, subjecting live fish to a potentially deadly test to save others is a bitter irony. And it's one that a team of scientists from the RETERO research project hopes to eventually mitigate with a robotic fish for testing.
EM corresponded with Olivier Cleynen and Stefan Hoerner from the University of Magdeburg about the complex flow conditions that set the parameters for the project.Read More
News stories about dogs getting sick from harmful algal blooms (HABs) in lakes have caused worry among members of the public this summer more than once.

“We just launched the HAB Citizen Scientists program this year,” explains Dr. Schnars. “It helps us work with people, especially people who spend time at marinas frequently, that are out there all season long.”
The season for boaters at Presque Isle, where RSC is located, starts in mid-May and usually continues through the beginning or middle of October.Read More
