The Rapid Pulse sensor works similarly to a Polarographic sensor. The system is completed by a voltage of 1.0 V and oxygen is reduced at the cathode. The difference is that the Rapid Pulse sensor pulses on and off during the measurement allowing the oxygen to replenish at the membrane surface. This results in almost zero flow dependence.
Calibration is dependent on usage but YSI recommends calibrating before starting each day.

Despite the high profile of plastic pollution in the ocean, the same problem in the Great Lakes is not well understood.
“Believe it or not, we’re kind of in the early stages of understanding plastic pollution in the Great Lakes,” said Sherri Mason, sustainability coordinator and professor of chemistry at Penn State—Behrend . She’s one author of research published in January in the Journal of Great Lakes Research examining the levels of plastic in Lake Erie and, for the first time, Lake Ontario.
[bctt tweet="The research revealed the highest level of plastic pollution in any of the Great Lakes occurs in Lake Ontario. Lake Erie was a distant second.Read More
Engineers and scientists that specialize in aquatic measuring practices always meet extra costs on the path to deployment. Maybe it is the corrosive nature of the saltwater, or the unbearable pressure tools must be equipped to handle while lying on the ocean floor.
For anyone interested in hooking up with the MARS (Monterey Accelerated Research System) Observatory , which rests dozens of miles off the California coastline, the costs extend further. They get so high that only well-funded universities and governmental agencies can afford to connect with the underwater power and data hub.
Hoping to lower that cost, engineers with the Monterey Bay Aquarium Research Institute ( MBARI ) constructed a wireless device called Deep-Sea Connect.Read More
During an electronic monitoring conference in February, fisheries managers and fishermen watched a squiggly purple line meander across the screen. It was mapping the journey a tuna fish was taking, from being caught and landing across the deck of a fishing vessel.
Leigh Habegger, executive director for Seafood Harvesters of America , a national commercial fishing group, said everyone in the crowd had their eyes glued to the screen.
“It was fascinating, it was really cool,” she added.
The graphic was the manifestation of a machine-learning tool that was trained to follow where a fish ended up after it was caught.Read More
