A large, deep, ice-covered lake has rapidly disappeared on the surface of an Antarctic ice shelf, probably due to the water’s own weight. The rare event occurred during the Antarctic winter of 2019 on the Amery Ice Shelf in East...
Researchers found a direct link between global dispersion of nickel-rich aerosols, ocean chemistry changes and the end-Permian mass extinction event that took place 251 million years ago.
The most severe mass extinction event in the past 540 million years eliminated...
Study sheds light on the future of the massive Thwaites Glacier. Researchers discover that instability doesn't always lead to rapid disintegration. This is the conclusion as researchers modeled the collapse of various heights of ice cliffs—near-vertical formations that occur...
Maori carving and weaving support the theory that Pacific Islanders were first to explore Antarctica pre-dating Maori arrival in New Zealand and before the first Westerners discovered Antarctica in the 1820s.
Polynesian seafarers likely reached Antarctica hundreds of years before...
New research suggests that the Hiawatha impact crater beneath ice could have been formed during the Pleistocene geological epoch. The 31-kilometer-wide crater first came to the world's attention in 2018 when a team led by the University of Copenhagen published research revealing its existence.
Hidden beneath...
The Greenland ice sheet contains the mass equivalent to raising global sea level by 7 meters. Research data revealed that a part of the Central-Western Greenland ice sheet has reached a critical threshold due to the last 100 years...
In a newly published paper, Virginia Tech geoscientists have found that shallow wastewater injection -- not deep wastewater injections -- can drive widespread deep earthquake activity in unconventional oil and gas production fields.
Brine is a toxic wastewater byproduct of...
Many miles of streams and rivers in the United States and elsewhere are polluted by toxic metals in acidic runoff draining from abandoned mining sites, and major investments have been made to clean up acid mine drainage at some...
A new focus article in the May issue of Geology summarizes research on plastic waste in marine and sedimentary environments. Authors I.A. Kane of the Univ. of Manchester and A. Fildani of the Deep Time Institute write that "Environmental pollution caused...
A new study found overlooked tsunami hazards related to undersea, near-shore strike-slip faults, especially for coastal cities adjacent to faults that traverse inland bays. Several areas around the world may fall into this category, including the San Francisco Bay...
Global sea level rise associated with the possible collapse of the West Antarctic Ice Sheet has been significantly underestimated in previous studies, meaning sea level in a warming world will be greater than anticipated, according to a new study...
