Microscopic ocean algae produce a huge share of Earth’s oxygen—but they need iron to do it. New field research shows that when iron is scarce, phytoplankton waste energy and photosynthesis falters.

Global efforts to reduce pollution will not be enough to mitigate the worst effects of climate change, scientists say. We will also need to extract over 10 gigatons of carbon dioxide from the ...

Tiny plastic particles drifting through the oceans may be quietly weakening one of Earth’s most powerful climate defenses.

Off the coast of Panama, a crucial ocean cycle failed to occur for the first time in decades. The expected nutrient-rich upwelling did not happen between January and April 2025, leading to warmer ...

Under the lead of the Leibniz Institute for Baltic Sea Research Warnemünde (IOW) the influence of parasitic fungi on the ...

Epaulette shark remain 'remarkably stable' throughout a reproduction process.

Oxygen isotopes data enable researchers to look far back into the geologic past and reconstruct the climate of the past. In doing so, they consider several factors such as ocean temperature and ice ...

Earth's oxygen-rich atmosphere faces a finite lifespan of about 1.08 billion years before a sharp decline, according to a ...

Far below the surface of the western Pacific Ocean, scientists have uncovered a geological system that reshapes how you may ...

Chlorophyll is the green pigment found in plants, algae, and cyanobacteria. It is essential for photosynthesis, the process ...
