Pink rocks reveal hidden granite mass under Antarctic glacier

March 18, 2026 Reported by AI Image generated by AI

Bright pink granite boulders on Antarctica's Hudson Mountains have unveiled a massive buried granite body beneath Pine Island Glacier. The structure measures nearly 100 km wide and 7 km thick. Researchers linked the rocks, dated to 175 million years ago, to this subglacial feature using gravity surveys.

Study finds hidden channels speed Antarctic ice melt

A new study shows that channels beneath Antarctic ice shelves can trap warm ocean water and accelerate melting from below. Researchers focused on the Fimbulisen Ice Shelf in East Antarctica and found that this process may make even cold regions more vulnerable. The findings suggest current climate models could underestimate future sea level rise.

Ancient Antarctic ice reveals modest greenhouse gas changes over 3 million years

April 25, 2026 Reported by AI

Scientists analyzing ancient ice from Antarctica have found that ocean temperatures dropped by 2 to 2.5 degrees Celsius over the past 3 million years, while carbon dioxide and methane levels changed only modestly. The studies, led by researchers from Oregon State University and others, suggest factors beyond greenhouse gases drove much of Earth's long-term cooling. The findings come from ice cores at Allan Hills in East Antarctica.

Antarctic meltwater provides less iron than previously thought

New research from Rutgers University reveals that meltwater from Antarctic ice shelves contributes far less iron to surrounding ocean waters than scientists had assumed. Instead, most iron originates from deep ocean water and continental sediments. The findings challenge expectations about iron fertilization and its role in carbon absorption.

Antarctic expedition transforms South African teens' perspectives on climate

A group of five South African students, including 17-year-old Luke Boswell from Gqeberha, recently returned from a transformative expedition to Deep Field Antarctica. The programme, led by adventurer Riaan Manser, aims to inspire young people to address environmental challenges through practical action. Participants describe profound shifts in their understanding of climate change and personal growth.

Iceberg A23a develops giant meltwater pool on surface

January 08, 2026 Reported by AI

A city-sized Antarctic iceberg known as A23a has formed a vast pool of meltwater on its surface, raising concerns it may soon break apart. Satellite imagery reveals an unusual raised ice rim holding billions of litres of water, resembling an oversized swimming pool. Scientists suggest this pooling could accelerate the berg's fragmentation in warmer waters.
