Global Water's pH sensor is a rugged reliable water pH measuring device.  The pH sensors are mounted on 25 ft of marine grade cable, with lengths up to 500 ft available upon request.  The pH sensor output is 4-20 mA with a three wire configuration.  The pH sensor's electronics are completely encapsulated in marine grade epoxy within a stainless steel housing (online version has 1 x 8 inch PVC pipe nipple, threaded both ends with cap).  The pH sensors also use removable shields and replaceable pH sensor elements for easy maintenance.

Global Water's GL500 pH Recorder adds recording capabilities to the pH sensors.  The GL500 pH Recorder connects to the pH sensor's 4-20mA output to record data.  In addition, Global Water offers the PC320 pH Controller to use the pH sensor's output to control pumps or alarms.

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.
