If the vast white expanse of Antarctica were to lose its frozen shell, an astonishingly rugged and alien world would emerge. Beneath 27 million cubic kilometers of ice lies a hidden continent sculpted by mountains, canyons, and valleys unseen for millions of years. Recent imaging projects have revealed this secret landscape with remarkable precision, changing how scientists understand the icy …

Scientists have identified 85 previously unknown lakes hidden beneath Antarctica‘s ice using a decade’s worth of satellite data. The newfound lakes are “active,” meaning they periodically drain and refill, changing size and shape over months and years, the researchers said. This subglacial activity affects the stability of glaciers and their grinding movement over the Antarctic bedrock, which in turn could …

A vast network of 332 submarine canyons has been discovered beneath Antarctica’s icy perimeter, dramatically expanding scientists’ understanding of how the continent interacts with global ocean systems. The findings, published in the peer-reviewed journal Marine Geology, stem from what researchers describe as the most detailed map ever produced of the Antarctic seafloor. The research, led by Dr David Amblàs of …

IN A NUTSHELL 🏔️ Beneath Antarctica’s ice, the ancient Transantarctic Mountains stretch over 2,175 miles, influencing ice flow and thickness. 🔬 Researchers use thermochronology to study tectonic movements and glaciation cycles, revealing Earth’s dynamic past. 🌡️ Discoveries, including fossilized trees, offer insights into past climates and help predict future climate changes. 🗺️ The hidden mountains act as a natural divide, …

A new scientific atlas has just redrawn the map of Antarctica’s seafloor—and what it reveals could alter how researchers model sea-level rise, ocean circulation, and the continent’s past. The study, published in Marine Geology and led by researchers from the University of Barcelona and University College Cork, identifies 332 previously unmapped submarine canyons hiding beneath the Antarctic margin—five times more …

Geologists Stumble on an Alien-Like Landscape Beneath Antarctica’s Ice  SciTechDaily Scientists discover long-lost giant rivers that flowed across Antarctica up to 80 million years ago  Live Science Extensive fluvial surfaces at the East Antarctic margin have modulated ice-sheet evolution  Nature Antarctica’s buried landscape may be slowing climate change, study finds  AOL.com Study indicate massive rivers flowed in Antarctica 80 mn years ago | Study …

Hidden beneath the thick ice sheet of East Antarctica, a team of researchers has uncovered the remnants of vast prehistoric river landscapes. These ancient, river-carved plains, preserved for millions of years, offer new insights into Earth’s distant past and could provide a clearer understanding of how Antarctica’s ice sheets may evolve in the future. Ancient River Systems Beneath East Antarctica …
