Investigating the Mackenzie Polynya - a Wind-Made Window in East Antarctica’s Sea Ice

September 15, 2026

The Mackenzie Polynya, an area of open water or thin ice that persists within the surrounding winter sea-ice pack, forms in Prydz Bay. Although they may appear to be small gaps in the Antarctic sea-ice cover, polynyas play an outsized role in the Southern Ocean system. They are major sites of sea-ice formation, contributing to the production of dense, cold water that helps drive global ocean circulation.

Giant Fan-Shaped Structure Discovered Beneath East Antarctica’s Ice

September 12, 2026

A vast geological structure hidden beneath the East Antarctic Ice Sheet is offering scientists a new way to understand both Antarctica’s ancient past and the behaviour of its ice today. The findings may help explain events linked to the evolution of the supercontinent Gondwana and the eventual separation of Antarctica from Australia.

Hidden Mounds of the Ross Sea Under Investigation

September 11, 2026

Hundreds of circular seafloor features have been found on the sea bed of the Ross Sea, at depths of between 300 and 1,200 meters. Their origin remains uncertain, making them one of Antarctica's more intriguing geological puzzles. Early hypotheses range from fluid or gas-related processes to the interaction of oceanographic and sedimentary forces over long timescales.

The Ross Sea May Be Fixing Carbon in the Dark

September 08, 2026

When most people think about ocean carbon uptake, they picture microscopic plants near the sea surface using sunlight to convert carbon dioxide into organic matter through photosynthesis. However, new research suggests that microorganisms living deep beneath the Ross Sea are helping to capture carbon in complete darkness.

Glass Eyes Beneath the South Pole

September 08, 2026

During the 2025-26 Antarctic summer season, the international IceCube collaboration completed a major upgrade of the IceCube Neutrino Observatory at the South Pole. The new equipment is expected to improve the observatory’s ability to detect low-energy neutrinos, elusive particles that can travel across the cosmos largely unaffected by matter.

The Green Mud Beneath the Ice: What SWAIS2C Has Actually Found

September 05, 2026

The presence of diatoms (microscopic algae that thrive in sunlit ocean waters) suggests that the area was once an open marine environment rather than being permanently covered by an ice shelf. If confirmed through further analysis, the findings would provide direct evidence that the Ross Ice Shelf collapsed and parts of the West Antarctic Ice Sheet retreated during warmer periods in Earth's past.
