Superoxide: A Super Sink of Ocean Oxygen
Ever wondered how oxygen gets depleted in the ocean? A new study suggests that a significant fraction is transformed into superoxide – an intriguing molecule that biologists love to hate. Amanda SemlerI’m a PhD candidate in Earth System Science at Stanford University, and I study how microbes in deep ocean sediments produce and consume greenhouse […]
Antarctic Eddies Suck Carbon from the Atmosphere
A recent study from researchers at the University of Tasmania investigates the relationship between ocean eddies and phytoplankton growth in the Southern Ocean using satellite data. The results can help us understand and predict how the ocean’s ability to regulate climate might change in the future. Channing PrendI’m a physical oceanography PhD student at Scripps […]
MAC-EXP: A new sediment corer designed to maintain in situ pressure conditions
The MAC-EXP, a pressure-coring experimentation and cultivation system, was designed to advance our ability to analyze the microbial processes in the deep-sea sediments, which is typically a challenge because the pressure change upon recovery can alter the in situ state. Jackson et al. (2017) describe the result of the systems first field trials. Anne M. […]
