ESPniagara Tracks Algal Toxins In Lake Erie, Protects Drinking Water

It may have taken 20 years and $20 million to develop, but Lake Erie researchers working to fight harmful algal blooms (HABs) now have a new tool to safeguard drinking water: ESPniagara. The advanced sampler has been called a “lab in a can” for its ability to sample microcystins, the most common algal toxin these days, in almost real time. The big gadget’s name is a mashup between “ESP,” for environmental sample processor, and the name of Admiral Oliver Hazard Perry’s ship during the War of 1812. “We wanted to name it something that was significant to Lake Erie,” said Tim Davis, molecular biologist and lead HABs researcher at the National Oceanic and Atmospheric Administration’s Great Lakes Environmental Research Lab (NOAA GLERL) in Ann Arbor, Mich.

Dynamics Of Fluid Movement Studied From Space

As a research project underway at the University of California (UC) - Santa Barbara shows, sometimes you’ve got to leave the Earth to adequately study some of its most basic processes. Researchers at the university are partnering with the International Space Station to complete an investigation of fluid dynamics. The lab in microgravity is providing them with an important dataset for gauging the impacts of the force on our planet’s fluid movement. The experiments in space , to be run by astronauts, are fairly straightforward. Cameras will be employed to monitor different sediment particles as they interact with one another in fluid in near-zero gravity. Light shone at and through the setups will help researchers track the motion and observe the density of the particles.

Rhode Island Streams Surveyed With Handheld Water Quality Meters, Nets

A sampling project led by University of Rhode Island researchers is helping to reveal the dynamics of aquatic health in three streams while supporting undergraduate education and local drinking water. The effort, relying on dip nets and handheld water quality meters, also gave students the chance to connect with Rhode Island’s hydrology. For Britta Anderson, graduate student in the department of geosciences at the university, the project offered something else. “Last summer was my first summer, so I had experience and the knowledge from that,” said Anderson, who oversaw undergraduate students who assisted during this year’s leg of the project. “I was able to continue this summer as more of a mentor.
