Supercomputers may help predict climate changes locally

Even a century ago, scientists working out equations on paper understood that gases in the atmosphere absorbed and emitted energy, keeping Earth from being a ball of ice. Today they use supercomputers to make increasingly ...

Rising oceans - too late to turn the tide?

Melting ice sheets contributed much more to rising sea levels than thermal expansion of warming ocean waters during the Last Interglacial Period, a UA-led team of researchers has found. The results further suggest that ocean ...

Warming ocean layers will undermine polar ice sheets

Warming of the ocean's subsurface layers will melt underwater portions of the Greenland and Antarctic ice sheets faster than previously thought, according to new University of Arizona-led research. Such melting would increase ...

New NASA salt mapper to spice up climate forecasts

Salt is essential to human life. Most people don't know, however, that salt -- in a form nearly the same as the simple table variety -- is just as essential to Earth's ocean, serving as a critical driver of key ocean processes. ...

New map reveals giant fjords beneath East Antarctic ice sheet

Scientists from the U.S., U.K. and Australia have used ice-penetrating radar to create the first high- resolution topographic map of one of the last uncharted regions of Earth, the Aurora Subglacial Basin, an immense ice-buried ...

Quantifying melting glaciers' effect on ocean currents

(PhysOrg.com) -- A team of scientists from Bangor University and the University of Sheffield have used a computer climate model to study how freshwater entering the oceans at the end of ice-ages 140,000 years ago, affected ...

Eddies found to be deep, powerful modes of ocean transport

(PhysOrg.com) -- Researchers from Woods Hole Oceanographic Institution (WHOI) and their colleagues have discovered that massive, swirling ocean eddies -- known to be up to 500 kilometers across at the surface -- can reach ...
