Fossilized marine plankton tell the tale of the end Permian mass extinction
The worst mass extinction the Earth has ever seen occurred 252 million years ago. The boundary of the Permian and Triassic geological periods marked the demise of around 90 percent of marine species and 70 ...
Warming climates intensify greenhouse gas given out by oceans
Rising global temperatures could increase the amount of carbon dioxide naturally released by the world's oceans, fuelling further climate change, a study suggests.
Seeding oceans with iron may not confer promised climate benefits
Adding iron to the Southern Ocean may not have the climate benefits that advocates of geoengineering have hoped for, a new study suggests.
Puerto Rico probes darkening of Vieques bio bay (Update)
Authorities in Puerto Rico announced Wednesday they are investigating why a glowing bay that attracts thousands of tourists a year has grown dark in recent weeks.
Seashells provide million-year-old weather report
New research, published in Earth and Planetary Research Letters, led by scientists from the University of Cambridge, used plankton – tiny bugs, whose shells litter the ocean floors. By drilling into the ...
Reading ancient climate from plankton shells
Climate changes from millions of years ago are recorded at daily rate in ancient sea shells, new research shows.
Tiny sea creatures are heading for extinction, and could take local fisheries with them
(Phys.org) —A species of one of the world's tiniest creatures, ocean plankton, is heading for extinction as it struggles to adapt to changes in sea temperature. And it may take local fisheries with it.
Tiny plankton could have big impact on climate
As the climate changes and oceans' acidity increases, tiny plankton seem set to succeed. An international team of marine scientists has found that the smallest plankton groups thrive under elevated carbon ...
Playing tag with sharks off the west coast of Scotland
Twenty-seven basking sharks have been tagged in the second year of a project to find out more about their life cycle.
Researchers offer explanation for higher survival rate of freshwater organisms after Chicxulub asteroid impact
First atlas on oceanic plankton
In an international collaborative project, scientists have recorded the times, places and concentrations of oceanic plankton occurrences worldwide. Their data has been collected in a global atlas that covers ...
Microplastic pollution prevalent in lakes too
EPFL researchers have detected microplastic pollution in one of Western Europe's largest lakes, Lake Geneva, in large enough quantities to raise concern. While studies in the ocean have shown that these small bits of plastic ...
Fast-sinking jellyfish could boost the oceans' uptake of carbon dioxide
Increasing numbers of gelatinous plankton might help in mitigating the CO2 problem. In field and laboratory experiments scientists from GEOMAR Helmholtz Centre for Ocean Research Kiel has shown that dead jellyfish and pelagic ...
The Black Sea is a goldmine of ancient genetic data: New study reconstructs the past ocean 'paleome'
When Woods Hole Oceanographic Institution (WHOI) marine paleoecologist Marco Coolen was mining through vast amounts of genetic data from the Black Sea sediment record, he was amazed about the variety of past ...
