The next generation YSI 6150 ROX is a luminescent-based dissolved oxygen sensor that offers YSI customers the most powerful tool for making long-term oxygen measurements in severe fouling and low oxygen environments. Its rugged design and large measurement range make it ideal for sampling, flow cell, and groundwater measurements.

The ROX optical sensor uses an integrated wiping system to provide anti-fouling in the most hostile environments. Durable mechanical features include a non-corroding titanium wiper shaft, replaceable wiper shaft seal, and a new switch controlled wiper parking system to prevent mis-parking.

The ROX sensing system is based on the luminescence lifetime method. This method was chosen because it offers the most stable, repeatable and sensitive method for oxygen detection, thus reducing sensor drift and prolonging deployment times.

YSI's optical DO membrane differs from the traditional electrochemical sensor membrane, requiring fewer steps for installation and less maintenance. ROX membranes will last for one year and are made of a durable material that is unlikely to be damaged in the field. The ROX sensor eliminates stirring dependency that was required of most traditional polarographic sensors.

VIMS study shows fish flee Chesapeake Bay hypoxia

A Virginia Institute of Marine Sciences study found that near-bottom fish in the Chesapeake Bay tend to move out of areas nearing hypoxia, according to a VIMS release. The study, which has spanned 10 years, found that biomass decreased in the middle of the Chesapeake Bay during mid-summer. That part of the bay typically experiences hypoxia due to algal blooms fed from nutrient runoff. A total of 48 sampling trips from 2002 through 2011 have shown that, when dissolved oxygen concentrations dip below 4 milligrams per liter, many near bottom fish leave the area. Analysis was limited to demersal, near bottom, fish and the same trends were not confirmed for fish higher in the water column.

Mississippi Gulf Coast fish kill expected to continue

Officials at the Mississippi Department of Marine Resources say that a recent fish kill along the state’s Gulf coast is the largest they’ve seen, according to KVUE . The fish kill has brought dead crabs, eels and stingrays ashore. Beachgoers were disturbed by the large-scale kill, but experts explained that conditions this year were to blame. With higher temperatures and low dissolved oxygen near the sea floor, creatures that live there were more likely to be affected. The fish kill, beginning July 1, was the first of 2013 for the area. It was expected to last several more days, but lessen over that period.

Extreme Wave Heights, Ocean Winds Increasing Globally

Around the world, extreme wave heights and ocean winds are increasing. The greatest increase is happening in the Southern Ocean, according to recent research from the University of Melbourne , and Dr. Ian Young corresponded with EM about what inspired the work. “Our main interest is ocean waves, and we are interested in wind because it generates waves,” explains Dr. Young. “Ocean waves are important for the design of coastal and offshore structures, the erosion of beaches and coastal flooding, and the safety of shipping.” Waves also have a role in determining how much heat, energy and gas can be trapped in the ocean. “The major reason why changes in wave height may be important is because of sea level rise,” details Dr. Young.
