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
A happy oyster is a happy tourist: Vester Field Station’s monitoring work on the southwest Florida coast
A clean environment doesn’t just mean improved biodiversity and fresher air. It also means increased real estate demand. That fact was cemented in 2015 after a Florida Realtor’s report tied hundreds of millions of property values to the Secchi disk depth of the surrounding water.
The report was explicit about how important the environment was and how it should be treated as such.
“Policymakers and the public would benefit from research into the possible effects of Everglades restoration on water quality in the estuaries of Martin and Lee Counties,” concluded the report.Read More
When pigs get out of their pens, they can really tear up a landscape. Five million pigs in 39 states can tear up a lot of landscape.
“They’re one of the top 100 invasive species in the world. Anywhere wild pigs are not natural and they show up, they do a lot of damage to other species,” said Dwayne Etter, a research specialist with Michigan’s Department of Natural Resources and a part of a research team that tested a new feral swine monitoring technique that uses environmental DNA.
Environmental DNA (eDNA) is genetic material organisms lose in the environment. If a pig crosses a creek or defecates in it, a researcher, in theory, should be able to pull that DNA out of the water further downstream.Read More
