Tiny Fossils Crack a Cretaceous Cold Case: Ocean Acidification Triggered One of the Ocean's Most Severe Extinctions

Tiny fossils crack a Cretaceous cold case: Ocean acidification triggered one of the ocean's most severe extinctions

A 113-million-year-old marine murder mystery may finally be solved. Using chemical clues locked inside microscopic fossils, Northwestern University scientists found evidence that ocean acidification drove one of the largest extinction events in the history of planktic foraminifera-tiny shell-building organisms that help regulate Earth's carbon cycle.

Interplay between nutrient limitation and ocean acidification: plankton community shifts in the oligotrophic western Bay of Bengal - Ocean Acidification

Highlights Abstract The perennial rise in atmospheric carbon dioxide (CO2) from anthropogenic activities increased oceanic carbon uptake, thereby lowering seawater pH. Rapid ocean acidification (OA) by 2 to 3 times than other regions of the same latitudinal belts was reported in the Bay of Bengal (BoB) due to the deposition of atmospheric pollutants, in addition […] The post Interplay between nutrient limitation and ocean acidification: plankton…
