Secchi Dip-in encourages citizen monitoring this summer

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.

Wildfire smoke alters a lake's ecology from the top to the bottom of the food chain

Wildfires have been big news the last couple of years. Australia’s wildfires in 2019 and 2020 made headlines around the world. The American west has had record-breaking burns in recent years, blanketing cities in dangerous amounts of smoke and sending haze across the continent to the east coast. For smoke's clearly apparent effects in the sky, new research finds it changed the ecology of Castle Lake, a freshwater lake in California, in 2018. “There are some studies that have analyzed the effect of human health in respiration with the smoke of wildfire,” said Facundo Scordo, a postdoctoral researcher at the Global Water Center of the University of Nevada—Reno.

New tech aims to make algal bloom monitoring faster, more dynamic

The fight against harmful algal blooms is getting a bit quicker, nimbler and more precise thanks to new technology that provides a cell-by-cell, colony-by-colony view of bloom make up and toxicity. “Typically a cyanobacteria community is highly variable. Certain species will dominate one week, and then another will dominate the next week or so,” said Dr. Scott Gallager, president of Coastal Ocean Vision, a company that hopes to change the way algal blooms are monitored with their new technology, Continuous Particle Imaging and Classification System (CPICS) and HABStats. The instruments, which measure algal blooms with a combination of imaging and spectroscopy, will provide water quality managers with a new, real-time monitoring tool to keep water safe and accessible.
