Human noise makes cod inactive. When it gets quiet again, they take off
She narrowly defied bureaucracy and spent days angling for cod. In the North Sea, marine biologist Inge van der Knaap discovered that noise significantly disturbs fish behavior. "There is now a lot of attention for underwater ...

Researchers investigate how climate change drivers reshape ocean methane and nitrous oxide cycles
The ocean is a critical life-support system for our planet through its role in global climate regulation. It absorbs most of the carbon emissions and heat trapped in the atmosphere, which result from human activities. Over ...

Why regional differences in global warming are critical
Tiny fossils in marine sediments verify that climate models provide accurate calculations of average ocean temperatures during the last glacial maximum around 20,000 years ago, but that the spatial distribution of simulated ...

Unexpected discovery at the air-water interface for CO₂ reaction impacting geophysical and biological cycles
Ocean acidification, mammal respiration, and aerosol formation all depend on chemistry that occurs at air-water interfaces. In new research, scientists from the Department of Energy's Lawrence Berkeley National Laboratory ...

Deoxygenation levels similar to today's played major role in marine extinctions 200 million years ago
Scientists have made a surprising discovery that sheds new light on the role that oceanic deoxygenation (anoxia) played in one of the most devastating extinction events in Earth's history. Their finding has implications for ...

Separating out signals recorded at the seafloor
Blame it on plate tectonics. The deep ocean is never preserved, but instead is lost to time as the seafloor is subducted. Geologists are mostly left with shallower rocks from closer to the shoreline to inform their studies ...

Tracing multiple evolutionary trajectories in aquatic crocodiles
In the geological past, several groups of crocodiles evolved towards a morphology adapted to marine life. However, the extent of these adaptations and their evolutionary trajectories remained unknown. An exhaustive study ...
