Trade winds ventilate the tropical oceans

Long-term observations indicate that the oxygen minimum zones in the tropical oceans have expanded in recent decades. The reason is still unknown. Now scientists at the GEOMAR Helmholtz Centre for Ocean Research Kiel and ...

Evolution stuck in slime for a billion years

Tasmanian researchers have revealed ancient conditions that almost ended life on Earth, using a new technique they developed to hunt for mineral deposits.

Decoding material fluxes in the tropical ocean

How is vital oxygen supplied to the tropical ocean? For the first time, oceanographers at GEOMAR Helmholtz Centre for Ocean Research Kiel were able to make quantitative statements regarding this question. They showed that ...

Gulf of Mexico could see record 'dead zone'

The Gulf of Mexico could see a record-size dead zone this year of oxygen-deprived waters resulting from pollution, US scientists have cautioned based on government data models.

Robot gliders roam seas

(Phys.org) —Once the robotic gliders scour the ocean searching for potential harm to sea life, the data is sent to David Caron, professor of biological sciences in USC Dornsife, and other marine biologists. They use the ...

VISIONS: Seeing the aurora in a new light

On a cold February night in Poker Flat, Alaska, a team of scientists will wait patiently for the exotic red and green glow of an aurora to illuminate the sky. Instead of simply admiring the view, this group from NASA's Goddard ...

Solution to ancient rock puzzle posited

A superplume, or massive episode of volcanic eruptions that related to extensive melting of the Earth's mantle, could explain the puzzling reappearance of major iron formations long after the rise in atmospheric oxygen about ...
