FLAMe sampler enables unprecedented snapshots of surface water quality

While limnologists are well-versed in tracking how a lake or river changes at a single point over time, a new homespun, high-speed sampling rig could soon help scientists capture a snapshot of how water quality varies across a water body's entire surface. The Fast Limnology Automated Measurement platform, or FLAMe, is a boat-mounted water intake system that analyzes surface water quality with advanced sensors while traveling "as fast as your boat can go, essentially," said John Crawford, a USGS research ecologist. Crawford started working on the FLAMe platform while a graduate student at the University of Wisconsin's Center for Limnology, where he said his supervisors first scoffed at the concept before coming around.

Private effort aims to wire Lake George into world's 'smartest lake'

As part of IBM’s Smarter Planet initiative, the company has poured millions into projects around the world to test out some of its new technologies and has gotten some good clippings in the press along the way. One well-known offshoot of this effort is Watson, the computer that famously beat human opponents at Jeopardy. But the initiative goes much farther than Watson, and some of the same engineers who worked on the supercomputer project have already turned their eyes to another one: the Jefferson Project, a joint effort between IBM, The FUND for Lake George and the Rensselaer Polytechnic Institute that is pushing the limits on lake monitoring.

YSI improves EcoSense handhelds

YSI recently released updated versions of the economical EcoSense handheld environmental testing devices that edge the EcoSense line closer to high-end handhelds. The update resulted from an aging product and feedback from the people who used the original versions every day, said YSI Product Manager Laura St. Pierre. “We were just trying the make it a better field tool,” she said. The new EcoSense pH100A, D0200A and EC300A replace products with the same names sans the “A.” While there wasn’t a drastic name change, the two model versions look completely different. Updated EcoSense models have an ergonomic design that better fits the palm. The curvaceous, gray case looks much cleaner than the previous version’s angular blue features.
