Teach Me About the Great Lakes podcast features an episode about hypoxia in Lake Erie. This monthly podcast produced by Illinois-Indiana Sea Grant released an episode entitled Hypoxic Layer on the Bottom that focuses on hypoxia in the Great Lakes, including Lake Erie.
Global study of hypoxia in rivers shows it is more prevalent than previously thought. New research from the University of Nevada, published in the journal Limnology and Oceanography Letters in January 2023, shows hypoxia in rivers and streams is generally much more prevalent across the globe than previously thought. The research compiles over 118 million readings of dissolved oxygen and temperature taken from over 125,000 locations in rivers across six continents and 93 countries and spanning over 100 years, from 1900 to 2018.

How big was the Gulf of Mexico dead zone in 2020? - Larger than the state of Rhode Island! Read about it in the report from the 2020 Shelf-wide Hypoxia Cruise from Louisiana State University and Louisiana Universities Marine Consortium
Mapping hypoxia using sound - A Swedish and American team of scientists have developed a method, using echo sounders, to map hypoxic and anoxic areas in the Baltic Sea. Read the summary about it on the Baltic Sea Centre's website here.
Study reconstructs Baltic cod growth rates over time - SLU-Aqua Ph.D. student Monica Mion and her advisor Michele Casini, together with 11 co-authors, published a study that reconstructed growth rates of Baltic cod from tagging data from 1955 to 2019. They found that growth rates are at all time lows currently, and hypoxia is thought to be one of the primary causes. Read the SLU press release here.
