High-Resolution Chart Reveals 332 Antarctic Submarine Canyons
EAST ANTARCTICA, JUL 22 – A continent-wide study finds East Antarctic surface meltwater now covers 3,732 square kilometers on average, increasing ice sheet vulnerability and potential future sea level rise.
- In a new Nature Climate Change paper, researchers used cloud computing to analyze 133,497 satellite images, revealing increased meltwater ponding on the East Antarctic ice sheet.
- Scientists predict that surface meltwater is increasingly important for Antarctic mass loss as atmospheric temperatures rise, driving East Antarctic ice sheet sensitivity.
- Surface meltwater covered an average of 3,732 km², and meltwater variability suggests increased susceptibility to ponding, which `Dr. Pete Tuckett` highlighted as impacting ice sheet stability.
- Experts caution that, `Dr. Pete Tuckett` explained, the research has significant potential to change how policymakers view Antarctic ice sheet stability.
- Looking ahead, Dr. Pete Tuckett added that combining this dataset with climate models will improve future impact predictions and understanding of meltwater effects, as noted by James Lea.

New map reveals 332 Antarctic submarine canyons, five times more than before
Submarine canyons are among the most spectacular and fascinating geological formations to be found on our ocean floors, but at an international level, scientists have yet to uncover many of their secrets, especially those located in remote regions of Earth like the North and South Poles.
Researchers issue warning after making concerning discovery in Antarctica: 'It's a global story'
Surface meltwater is increasing in East Antarctica, raising concerns about the future of the ice sheet. What's happening? The University of Liverpool in a news release said this was "the first Antarctic-wide, high-resolution monthly dataset of surface meltwater using satellite images." Changes to the region's ice due to rising temperatures could cause mass loss and subsequent catastrophic sea-level rise. The study, published in Nature Climate Ch…
