The Ice Week
CW 42 · October 10th to 16th, 2026
Antarctica is nearly one and a half times the size of Europe, and yet every week shows how little we know about it. This week: a hidden zone under the so-called Doomsday Glacier, a penguin species that no one noticed for a hundred years, and a silent power struggle over the sea off the continent.
The top 5 of the week
What counted this week
What lay hidden under the Doomsday Glacier
Radar images from ICEYE satellites reveal: under the Thwaites Glacier, there is no clear boundary between ice on rock and floating ice, but rather a 2 to 5 kilometer-wide zone into which seawater intrudes. This doubles the glacier's expected contribution to sea-level rise by 2100. Of all places, the best-monitored glacier in Antarctica had such a surprise underneath it.
Power struggle over the Southern Ocean
Ahead of the meeting of the Antarctic marine commission CCAMLR in Hobart starting October 19, reports indicate that China plans to propose its own protected area, designated as the "Cosmonaut Sea." It is intended to exclude krill fishing grounds, apply only seasonally, and expire after 20 years—roughly when the Antarctic mining ban can be reviewed via a special procedure starting in 2048. Environmental organizations, conversely, are pushing for the large protected area on the Antarctic Peninsula.

Overlooked for a hundred years: a new penguin species
On the sub-Antarctic Kerguelen Islands, researchers have described a distinct penguin species, the first new species in over a century. It looked so similar to known relatives that only DNA, body size, and calls revealed the difference. If a penguin could hide for so long, what are we missing on the continent itself?

The penguin die-off had a different cause
When thousands of Adélie penguins died on the Danger Islands off the Antarctic Peninsula in 2024, bird flu was considered the obvious explanation. Laboratory tests now show: 46 out of 49 carcasses carried the avian cholera pathogen, with only a few carrying H5N1. The initial explanation was not the correct one.

The world's largest penguin colony has lost its title
On the volcanic island of Zavodovski, the number of chinstrap penguin nests has shrunk by about 63 percent since 2011, from approximately 543,000 to 201,000, according to the British Antarctic Survey. The primary reason is considered to be krill migrating southward. As a result, Cape Adare in the Ross Sea is now the largest colony.

Why is no one actually drilling?
Since Russian seismic surveys in the Weddell Sea, the figure of 511 billion barrels of oil beneath Antarctica has been circulating—more than the proven reserves of Saudi Arabia. It is not publicly verified; Moscow describes it as geological mapping. The Antarctic Treaty’s environmental protocol prohibits extraction; this ban can be reviewed starting in 2048. That almost all nations have adhered to it for decades is one of the most astonishing agreements in the world. And China’s limited proposal for a protected area shows that some are already looking toward the time thereafter.
No news this week: Subglacial lakes like Vostok, the Gamburtsev Mountains, flight paths and exclusion zones, Operation Highjump and Admiral Byrd, as well as meteorites and the oldest ice remained quiet this week. We also found no new findings that could be verified in forums where satellite images are searched for strange shapes.

Sea ice on a downward record course
Following the third-lowest winter maximum of the satellite era, Antarctic sea ice has fallen daily below previous record lows since October 2nd. Why the ice around Antarctica has been reacting so differently since 2016 compared to long-standing predictions is one of the great open questions in polar research.

A cubic kilometer of ice as a telescope
The 2026 Nobel Prize in Physics went to Francis Halzen, head of the IceCube Observatory at the South Pole. Sensors deep in the ice capture neutrinos from space there. The award ceremony is on December 10th in Stockholm.

A green beam over the South Pole
The webcams of the Amundsen-Scott Station show the green laser beam of the atmospheric lidar rising vertically into the sky after the polar night. A silent, almost graphic motif circulating daily through the Mastodon community.

The expedition season begins
With the southern summer, shipping companies are starting their season: Seabourn is planning 19 Antarctic trips from Ushuaia starting in November, and Antarctica21 will welcome its first guests on a new ship in mid-December. The continent remains strictly limited for visitors, with landings occurring only in authorized areas.
