Ocean acidification does not impair the behaviour of coral reef fishes

AbstractThe partial pressure of CO2 in the oceans has increased rapidly over the past century, driving ocean acidification and raising concern for the stability of marine ecosystems1,2,3. Coral reef fishes are predicted to be especially susceptible to end-of-century ocean acidification on the basis of several high-profile papers4,5 that have reported profound behavioural and sensory impairments—for…

Ocean microbes: Novel study underscores microbial individuality

A single drop of seawater can contain a wide representation of ocean microbes from around the world — revealing novel insights into the ecology, evolution and biotechnology potential of the global microbiome. A new publication in Cell reports a staggering degree of biological diversity that defies contemporary definitions of microbial species, illuminates reasons behind challenges…

Bacteria from the ocean floor could be influencing Arctic weather

There’s more to clouds than you might think. Phytoplankton bloom in the Chukchi Sea in 2018. (Norman Kuring/NASA’s Ocean Color Web, using Landsat data from the U.S. Geological Survey) Scientists have identified a surprising new mechanism that could be affecting cloud formation and weather patterns in the Arctic: bacteria from the ocean floor. When tiny,…

Ocean ecosystems take two million years to recover after mass extinction – new research

Around 66m years ago, a giant asteroid struck the Earth, causing the extinction of the dinosaurs, ammonites, and many other species. The asteroid was equally devastating at a microscopic level, driving ocean plankton to near-extinction. This crippled the base of the marine food chain and shut down important ocean functions, such as the absorption and…

Ocean drilling revolutionized Earth science — now geologists want to plumb new depths

The JOIDES Resolution is the workhorse of the world’s fleet of ocean-drilling research vessels. Credit: David Wong/Getty This month, off the coast of Ecuador, scientists are hunting for hot, teeming masses of microbes living in two long, skinny holes drilled into the bottom of the ocean.This cruise, aboard the legendary research ship JOIDES Resolution, is…
