The YSI EcoSense instruments provide accurate data in the most affordable package. The "M" stands for memory and the instruments feature a real-time clock, larger memory and simple data transfer to a PC with a built-in USB port. The EC300M is easy-to-use, field-ready and utilizes a stable, 4 nickel electrode sensor design that results in accurate measurements. The EC300M measures conductivity, specific conductance, salinity, TDS (Total Dissolved Solids) and temperature with the following features:
- Rugged, waterproof, field-worthy case. IP-67 rated.
- Durable field probe and cables made in the USA. 1-,4- and 10-meter field cables available.
- Waterproof micro-USB port for transferring data to PC; no software required.
- Holds 250 data sets; no need to write down data.
- Real-time clock for date/time stamp of saved data.
- User-selectable re-calibration prompt provides reminder to calibrate.
- Automatic temperature compensation.
- Stable, four-electrode design provides accurate field measurements.
- 1-year warranty on instrument and probe/cable assembly.
The EC300M is designed for quick, accurate results in an economical platform. Easy-to-use, waterproof and backed by a 1-year warranty, the EC300M is ideal for a wide-range of applications.

Charles River Algal Blooms Stop Swimming and Launch a Floating Wetland
The Charles River used to be a swimming hotspot for Cambridge and Boston residents. 
 
 Decades of industrial pollution and nutrient runoff have degraded water quality and eliminated public swimming in the Lower Charles, but a movement is afoot to get Boston and Cambridge back in the water. One step toward the goal of a safely swimmable river—without the need to obtain a permit, as is now necessary—is detecting and managing the harmful algal blooms that appear on the river. 
 
 An experimental floating wetland and new research and analysis of water quality data that shows a possible effective detection system for algal blooms on the Charles River are two new steps toward the goal of safe, accessible swimming.
Read MoreHarnessing the Gulf Stream for Renewable Energy
The Gulf Stream, the massive western boundary current off the east coast of North America, moves water from the Gulf of Mexico north and west across the Atlantic Ocean. There’s a lot of energy in that much moving water and researchers are trying to put it to use. 
 
 Although the Gulf Stream’s path shifts (researchers say it acts like a wiggling garden hose), in a couple of spots, it stays relatively stable. At one such spot off the coast of Cape Hatteras, North Carolina, researchers have dropped moorings and research instruments to study the current with the eventual goal of harnessing it for renewable energy.
Read MoreBuoys in the time of Covid: Delays to important information
In early 2020, Michigan found itself facing one of the worst outbreaks of Covid-19 in the country. Though it’s close to second nature now, businesses, schools and governments were suddenly forced to conduct business without close contact. Universities and research institutions had to pause some scientific research. Whatever was able to continue slowed to a crawl. 
 
 Around the Great Lakes, a network of buoys monitors dozens of water quality parameters and lake conditions, reporting them in real time. This year, the monitoring season was cut a bit short as Covid-19 restrictions hit in the weeks before buoys were set to be deployed.
