When Howard Webb set out to monitor turnover in Whitecliff Quarry Lake, his custom-built system of temperature sensors worked perfectly. Until the muskrats showed up.
Webb, a volunteer with the Lakes of Missouri Volunteer Program , devised an inexpensive array to monitor the lake in St. Louis’ Crestwood suburb. His design for looking at the effect of temperature turnover on algae cycling centered on iButtons, small metal loggers that were very reliable, but not waterproof.
That meant Webb had to find an equally inexpensive way to keep them dry. The solution? Small Nalgene water bottles to hold the loggers. Muskrats, however, mistook the bottles - which became covered in algae - for food, tearing into them and flooding the iButtons.
“We thought, ‘Let’s give this a try.Read More
As we hear more and more about algal blooms of different kinds across the United States, teams of scientists are working hard to ensure that they don't become our new normal. One project in Florida is taking a multi-disciplinary approach to the problem—including genetic analysis.
The team's work is part of a full-court press in Florida recently, making a serious push to understand what is triggering more frequent blooms. Jose Lopez, Ph.D. , of Nova Southeastern University , the primary investigator on the genetic analysis portion of the project, spoke to EM about the project and his work on it.
“This is a very good project,” explains Dr. Lopez. “We're excited about it, and it's a lesson in persistence.”
From extreme weather such as Hurricane Harvey to spills and other accidents, the Gulf Coast of Texas is no stranger to dangerous situations. This is where the data provided by the Texas Automated Buoy System ( TABS ) comes into the picture.
Among the nation's most successful and longest-running coastal ocean-observing systems at the state level, the TABS real-time oceanographic buoy system monitors currents, waves, salinity, winds, and other parameters. Dr. Anthony Knap , director of Geochemical Environmental Research Group (GERG) and a Professor of Oceanography at Texas A&;M University, spoke to EM about working with TABS.
“TABS has been running now for 24 years,” explains Dr. Knap.Read More
