reference potentials.
The electrode uses an improved sodium-selective glass membrane containing an inner filling solution with a constant sodium ion concentration and glycerol as an antifreeze agent. The
glass is a LAS (lithium aluminosilicate) glass. Special doping agents in the glass improve selectivity for sodium ions. A potential develops across the membrane that is proportional to the
sodium concentration in the standard or sample.

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.

Harnessing 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.

Buoys 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.
