Here’s a new paper from our team led by Olivia Mason at FSU
“The northern Gulf of Mexico (nGOM) hypoxic zone is a shallow water environment where methane, a potent greenhouse gas, fluxes from sediments to bottom water and remains trapped due to summertime stratification. When the water column is destratified, an active planktonic methanotrophic community could mitigate the efflux of methane, which accumulates to high concentrations, to the atmosphere. To investigate the possibility of such a biofilter in the nGOM hypoxic zone we performed metagenome assembly, and metagenomic and metatranscriptomic read mapping”. Read more…

Our latest paper is out in Nature Communications
Our latest paper is out in Nature Communications describing how “Aerobic oxidation of methane significantly reduces global diffusive methane emissions from shallow marine waters”
“Here we investigate methane sources and fates in the East China Sea and map global MOx rates in shallow waters by training machine-learning models. We show methane is produced during methylphosphonate decomposition under phosphate-limiting conditions and sedimentary release is also source of methane”. Read more…

Our latest paper is out in Geophysical Research Letters
“We visited a remote, extremely cold, and salty desert pond in the Dry Valleys of Antarctica, an environment that is considered to be among the most similar to Mars that can be found on Earth. There, we studied the production of nitrous oxide in the absence of microbial life. We show that this gas is produced through the interaction between rock and chemical precursors in water at extremely cold temperatures (−40°C) that are similar to those observed on Mars”. Read more…
Samantha Joye participates in Schmidt Ocean Institute’s Ocean Rising: The Quest to Inspire the Public Virtual Workshop
The ocean is the backbone of climate and life on this planet. Resources in the ocean enable life to thrive across Earth, but this is taken for granted and rarely recognized for the role it plays in planetary and human health. To change this status quo, we need to inspire the public about the ocean as they are inspired by space and this workshop, organized by the Schmidt Ocean Institute and Nekton, aims to do that.
