How nutrients are removed in oxygen-depleted regions of the ocean

In the course of global climate change, scientists are observing the increase of low-oxygen areas in the ocean, also termed oxygen minimum zones (OMZs). Large-scale OMZs exist, for example, in the Pacific off the coast of ...

The oceans were once colder than previously believed

A team of EPFL and European researchers has discovered a flaw in the way past ocean temperatures have been estimated up to now. Their findings could mean that the current period of climate change is unparalleled over the ...

Atom-by-atom growth chart for shells helps decode past climate

For the first time scientists can see how the shells of tiny marine organisms grow atom-by-atom, a new study reports. The advance provides new insights into the mechanisms of biomineralization and will improve our understanding ...

Clues to paleoclimate from tiny fossils

New insights into the growth dynamics of minuscule marine organisms could help put the study of Earth's climate, both present and prehistoric, on a more solid footing.

Scientists solve a 14,000-year-old ocean mystery

At the end of the last Ice Age, as the world began to warm, a swath of the North Pacific Ocean came to life. During a brief pulse of biological productivity 14,000 years ago, this stretch of the sea teemed with phytoplankton, ...

Coccoliths thrive despite ocean acidification

Ocean acidification is damaging some marine species while others thrive, say scientists. An international team studied the effect of ocean acidification on plankton in the North Sea over the past forty years, to see what ...
