Scientists have long known earthquakes can cause the Earth to vibrate for extended periods of time. However, in 1998 a research team found the Earth also constantly generates a low-frequency vibrational signal in the absence ...

It is one of the great ironies of biochemistry: life on Earth could not have begun without water; yet water stymies some chemical reactions necessary for life itself.

Ocean circulation patterns have a profound effect on global climate. Waves deep within the ocean play an important role in establishing this circulation, arising when tidal currents oscillate over an uneven ocean bottom. ...

Surfers aren't the only people trying to catch big waves. Scientists at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) are trying to do so, too, at least in wave climate forecasts.

Oceanographers commonly calculate large scale surface ocean circulation from satellite sea level information using a concept called "geostrophy", which describes the relationship between oceanic surface flows and sea level ...

Low-frequency vibrations of the Ross Ice Shelf are likely causing ripples and undulations in the air above Antarctica, a new study finds. Using mathematical models of the ice shelf, the study's authors show how vibrations ...
