Overview
The YSI EcoSense DO200A meter simultaneously measures temperature and dissolved oxygen in a compact, handheld instrument. The DO200A simultaneously measures dissolved oxygen (% air saturation and ppm) and temperature. The DO200A is designed for quick, accurate results in an economical platform. The ability to measure DO and temperature in a simple, compact handheld allows the instrument to be used across multiple application sampling strategies from the field to the lab with the optional BOD probe.

Watershed groups handing tech to volunteers for better citizen monitoring
Watershed protection groups across the country are collecting water quality data on waterways that might otherwise miss out on monitoring entirely. Some have found that, despite small staffs, they can compile more high-quality data by putting water quality sensors and other professional scientific instruments in the hands of volunteers. For organizations like the Santa Barbara Channelkeeper, the reasoning for equipping volunteers with electronic handheld meters is clear: "We really want the data that we're collecting to be utilized," said Ben Pitterle, director of the group's watershed and marine program.
Moorings off Oregon coast give insights into dissolved oxygen dynamics
Each summer, deep ocean currents pull low-oxygen, high-nutrient water up onto Oregon's coastal shelf. This upwelled water is often implicated in the seasonal hypoxia that has become more frequent in the state's coastal waters. But a recent study of three summers of data from the ocean floor suggest that the upwelled water may also be the reason that matters aren't worse. Though scientists have known about the low-oxygen water making it's way onto the shelf for decades, the details of what happens once it gets there are foggy.
YSI improves EcoSense handhelds
YSI recently released updated versions of the economical EcoSense handheld environmental testing devices that edge the EcoSense line closer to high-end handhelds. The update resulted from an aging product and feedback from the people who used the original versions every day, said YSI Product Manager Laura St. Pierre. “We were just trying the make it a better field tool,” she said. The new EcoSense pH100A, D0200A and EC300A replace products with the same names sans the “A.” While there wasn’t a drastic name change, the two model versions look completely different. Updated EcoSense models have an ergonomic design that better fits the palm. The curvaceous, gray case looks much cleaner than the previous version’s angular blue features.
Testing CO2 Removal Strategies in the Pacific Northwest
The ocean plays a key role in carbon dioxide (CO2) removal and storage, also known as carbon sequestration. However, with increasing emissions, a large amount of CO2 escapes into the atmosphere, worsening climate change and leading to increases in surface temperatures. In order to mitigate some of these impacts, researchers like Ally Savoie at the Pacific Northwest National Laboratory (PNNL) are working hard to identify ways to safely improve the CO2 removal and storage capabilities in the ocean. Savoie started her career at Wright State University , where she worked in Silvia Newell’s lab examining biogeochemical cycling of nutrients in a river system. From there, she decided to pursue a master’s in marine science at the University of Southern Mississippi with Dr.
