Salt pond in Antarctica, among the saltiest waters on Earth, is fed from beneath

At the base of the Transantarctic Mountains lies a geological oddity. Don Juan Pond is one of the saltiest bodies of water on the planet, filled with a dense, syrupy brine rich in calcium chloride that can remain liquid to minus 50 °C (122 °F), far below the...

Mantle plume, a geothermal heat source under West Antarctic ice sheet

A new study adds to evidence that a geothermal heat source called a mantle plume lies deep below Antarctica's Marie Byrd Land, explaining some of the melting that forms lakes and rivers under the ice sheet. Although the heat source isn't a new or increasing...

Solving the mystery of rapidly rising Indian Ocean sea level

Sea levels around the world have risen by 1.7 millimeters (0.07 inches) on average each year since 1880, but in recent years, scientists have observed a rapid increase in sea level in the north Indian Ocean. Tide gauge records and other datasets reveal the pace of...

Decadal variation of relationship between East Asian monsoon and El Nino

East Asian summer monsoon (EASM) is one of the most dominant climate systems in East Asia. The anomalous EASM can cause extremely high temperatures, floods or drought. And the El Niño-Southern Oscillation (ENSO), the dominating mode in the tropical Pacific,...

Magma held in 'cold storage' before giant volcano eruption

Long Valley, California, has long defined the "super-eruption." About 765 000 years ago, a pool of molten rock exploded into the sky. Within one nightmarish week, 760 km3 (182 mi3) of lava and ash spewed out in the kind of volcanic cataclysm we hope never...

Cooling in high and mid-latitudes led to aridification in Northern Africa

Researchers from several European institutions found that northern high-latitude cooling played a role in triggering the rapid termination of the African Humid Period 5500 years ago. It is one of the driest regions of the Earth, yet, in a cave in the Egyptian...
