    Antarctica’s iceberg graveyard could reveal the ice sheet’s future

    Just beyond the tip of the Antarctic Peninsula lies an iceberg graveyard. 

    There, in the Scotia Sea, many of the icebergs escaping from Antarctica begin to melt, depositing sediment from the continent that had been trapped in the ice onto the seafloor. Now, a team of researchers has embarked on a two-month expedition to excavate the deposited debris, hoping to discover secrets from the...

    Collapsing ice cliffs may not contribute to sea level rise

    Sea level rise over the next century won’t get a feared boost from Antarctic ice cliffs crumbling into the ocean like dominoes, a new study suggests.

    The finding, published February 7 in Nature, is based on a new statistical analysis showing that such a rapid collapse of marine ice cliffs in Antarctica was extremely unlikely to have happened in the past, even during some of Earth’s...

    A drill built for Mars is being used to bore into Antarctic bedrock

    Once destined for Mars, a prototype drill has a new mission: To bore into rocks buried deep beneath the ice in Antarctica.

    In early January, researchers from the University of Glasgow in Scotland took a modified version of their Martian drill to Antarctica. They’re poised to send it down to the bottom of a 651-meter deep ice borehole completed January 10 by researchers with the British...

    Wind may be driving the melting of East Antarctica’s largest glacier

    View the video

    The wind is helping to awaken one of Antarctica’s sleeping giants. Warm ocean waters, driven inland by winds, are undercutting an ice shelf that holds back a vast glacier from sliding into the ocean, researchers report November 1 in Science Advances.

    Totten Glacier is East Antarctica’s largest glacier, with a drainage basin encompassing about 550,000 square...

    Zika, psychobiotics and more in reader feedback

    Zapping Zika

    As Zika virus spreads, researchers are racing to find Zika-carrying mosquitoes’ Achilles’ heel, Susan Milius reported in “Science versus mosquito” (SN: 4/2/16, p. 30). Some approaches include genetic sterilization so mosquitoes can’t reproduce and infecting them with bacteria to decrease their disease-spreading power.

    One reader had another suggestion. “Maybe we could just...

    Sea levels could rise twice as fast as previously predicted

    Antarctica’s meltdown could spur sea level rise well beyond current predictions. A new simulation of the continent’s thawing ice suggests that Antarctic melting alone will raise global sea levels by about 64 to 114 centimeters by 2100, scientists report in the March 31 Nature.

    Adding Antarctic melt to other sources of sea level rise, such as the expansion of warming seawater and melting...
