Antarctic drilling peers deep into ice shelf's past • Muser Press Scientists say they have drilled deeper than ever beneath the West Antarctic Ice Sheet, peering back millions of years to reveal signs it was once, at least

Scientists say they have drilled deeper than ever beneath the West #AntarcticIceSheet, peering back millions of years to reveal signs it was once, at least in part, open ocean.

Deep ocean temperatures challenge past views of the Antarctic ice sheet • Muser Press Understanding past Antarctic ice sheet behaviour relies on oxygen isotope ratios (δ¹⁸O) measured in deep-sea fossils. Traditionally, large Oligocene δ¹⁸O

A new study in Nature Geoscience shows that deep Southern Ocean temperatures in the Oligocene fluctuated by up to 4 °C, explaining the large oxygen isotope (δ¹⁸O) swings recorded in deep-sea #fossils, while the #AntarcticIceSheet remained relatively stable. DOI: doi.org/10.1038/s415... #Paleoclimate

Researchers issue dire warning about looming threat to coastal communities: 'Decisive' The scale of the threat can scarcely be exaggerated.

"the co-authors of this study are clear that more research into risks posed by Antarctic melt is needed. Accurate models will be essential"

Pleistocene terrestrial warming trend in East Asia linked to Antarctic ice sheets growth Despite the great potential of brGDGTs for paleotemperature reconstructions, the impacts of non-thermal factors, such as soil input, changes in water-column structure, water chemistry, and bacterial communities, and seasonal bias should be carefully evaluated prior to the quantitative application of...

How Rivers That Vanished 34 Million Years Ago Still Rule the Antarctic Ice Sheet Buried beneath a 3,500 kilometer stretch of East Antarctic ice sheet lies a hidden landscape that once hosted flowing rivers. Aand these ancient waterways now control how ice moves toward the ocean. Scientists using radar measurements have discovered extensive flat...

A long-lost Antarctic ice sheet could predict the future of New York City - one in which Lower Manhattan and Coney Island are 'perpetually submerged' An ice sheet that sprawled across North America during the Last Interglacial period may have stuck around longer than we thought, and that could spell trouble for New York City as the climate warms. On Oct. 29, 2012, Superstorm Sandy...

Antarctic ice sheet may be less vulnerable to collapse than expected The West Antarctic ice sheet could cause metres of sea level rise if it collapses – but more than 120,000 years ago, it may have survived an even warmer period than it is experiencing now
