How does a Rapid Pulse DO Sensor work?
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.
How often should I calibrate my DO sensor?
Calibration is dependent on usage but YSI recommends calibrating before starting each day.
A recent study of Appalachian Ohio drinking water from private wells found no evidence of natural gas contamination from “fracking” (drilling for oil and gas) despite concerns about the practice. University of Cincinnati geologists investigated drinking water in Carroll, Harrison, and Stark counties, a rural area in the northeast portion of the state, where private underground wells are the only source of drinking water for many residents.
Associate professor of geology Amy Townsend-Small described the time-series study, which is the first to measure sources and concentrations of methane in the fracking region of Ohio, to EM.Read More
Scientists from New Zealand's National Institute of Water and Atmospheric Research, NIWA , are engaging in sedimentation research to help determine the effects of seabed mining and fishing on the environment. This work represents some of the most challenging underwater research ever undertaken by the NIWA team.
The need for the work arises from the controversy surrounding proposed seabed ventures—each of which was met with serious opposition based on presumed environmental effects such as drifting sediment plumes. In an effort to determine the full environmental impacts of such seabed activities, the NIWA team has undertaken an unusual project deploying high-tech instruments on the ocean floor.

Marine Protected Areas (MPAs) are traditionally a haven for marine fauna under threat from human activities. However, new research confirms that greenhouse gases will continue to warm the world's oceans and reduce their oxygen concentrations, rendering most existing MPAs uninhabitable by 2100.
John Bruno , the study’s lead author , is a marine ecologist and biology professor in the College of Arts and Sciences at UNC-Chapel Hill. Dr.Read More
