The availability of sufficient dissolved oxygen in seawater is critical for marine life, and places where oxygen falls below a critical concentration — or “dead zones” — are often associated with mass die-offs of fish, shrimp and other creatures.
With future global warming, the oceans are on course to see progressively less dissolved oxygen available. Scientists currently use often not well-tested computer models to predict the expansion of dead zones, but a team of researchers from Wesleyan, University California Riverside and Syracuse University are hoping to use oceanic sediment samples to better predict where die-offs may occur next.
Their study, titled “Refining Foraminifera I/Ca as a Paleoceanographic Proxy for the Glacial Atlantic Ocean” was funded by a National Science Foundation grant on Aug. 16. The award, worth $423,739, will be awarded to the three universities over three years.
Ellen Thomas, University Professor in the College of Integrative Sciences, research professor in earth and environmental sciences, will use her share of the funds to support undergraduate student summer research fellowships.
