NASA's Operation IceBridge, an airborne survey of polar ice, recently finalized two overlapping campaigns at both of Earth's poles. Down south, the mission observed a big drop in the height of two glaciers situated in the Antarctic Peninsula, while in the north it collected much needed measurements of the status of land and sea ice at the end of the Arctic summer melt season.
A remarkably detailed animation of the movement of the densest and coldest water in the world around Antarctica has been produced using data generated on Australia's most powerful supercomputer, Raijin.
Researchers for the first time have attempted to measure all the material leaving and entering a mountain range over millions of years and discovered that glacial erosion can, under the right circumstances, wear down mountains faster than plate tectonics can build them.
Groundbreaking new research has shown that erosion caused by glaciation during ice ages can, in the right circumstances, wear down mountains faster than plate tectonics can build them.
Planet Earth experienced a global climate shift in the late 1980s on an unprecedented scale, fueled by anthropogenic warming and a volcanic eruption, according to new research published this week. Scientists say that a major step change, or 'regime shift,' in the Earth's biophysical systems, from the upper atmosphere to the depths of the ocean and from the Arctic to Antarctica, was centered around 1987, and was sparked by the El Chichón volcanic eruption in Mexico five years earlier.
Researchers at Aalto University have discovered that energy saving superconductors may be possible if the counterintuitive properties of electrons moving in 'flat bands' are exploited.
This week from AGU: Magma ocean, Underwater waves, & 5 new research papers.
Some parts of the Twin Cities can spike temperatures up to 9°F higher than surrounding communities thanks to the 'urban heat island' effect, according to a new study from the University of Minnesota.
A study by a team of US and Australian researchers shows that long-term warming of the Indian and Pacific oceans played an important role in increasing the severity of the devastating floods that struck Australia in 2010/2011. The researchers found that, during a strong La Niña, warmer sea surface temperatures make Australia three times as likely to experience rainfall levels akin to the 2010/2011 event.
A new study has found a link between abrupt ocean warming at the end of the last ice age and the sudden onset of low-oxygen, or hypoxic conditions that led to vast marine dead zones. Results of the study, which was funded by the National Science Foundation, are being published this week in the journal Nature.
