Ocean acidification

In this context, functional saturation is defined as the state in which a system’s capacity to sustain additional productive or regulatory functions becomes constrained due to cumulative anthropogenic pressures, even if some physical space remains available. This review examines whether the progressive contraction of terrestrial plant communities under intensifying anthropoge...

Feeding by marine invertebrate larvae depends critically on the low-Reynolds-number fluid mechanics of the feeding currents they generate. Yet the relative importance of gravity-driven versus drag-driven mechanisms in small invertebrate larvae has remained unresolved. Here, high-speed microscale imaging, micro-particle image velocimetry (μPIV), and an analytical axisymmetric ...

High-speed imaging reveals how oyster larvae’s dense shell helps them feed—and may offer clues to why ocean acidification threatens their survival Photos and video available for use with credits can be found here. Woods Hole, Mass. (September 16, 2026) — Eastern oyster larvae are only 100–300 micrometers long, but their dense calcium carbonate shells make […]

Ocean acidification from an interns viewpoint. My name is Ned Gable and I am currently an Environmental Science and Chemistry double major at the University of Mary Washington. I was born and raised in Richmond, Virginia. I am a PADI Divemaster who is passionate about marine ecology and the biogeochemical components of the ocean. I […]

Hypoxia in marine systems is expanding worldwide due to anthropogenic activities. Deep waters of the St. Lawrence Estuary and Gulf are rapidly deoxygenating (∼1 mmol O2 m−3 y−1), driven by changes in Atlantic water-mass intrusion and nutrient‐fueled remineralization, and are simultaneously acidifying (∼0.004 pH unit y−1). These changes alter biogeochemical cycles and degrade ...
