Antarctica

Ice core sample from the Patriot Hills area

Rising ocean temperatures drove the melting of Antarctic ice sheets and caused extreme sea level rise more than 100,000 years ago, a new international study led by UNSW Sydney shows.

This year's most popular science stories took readers from melting Antarctic ice sounding the alarm on microbes and climate change, to a pest-proof fence to protect native wildlife in far western NSW, and early signs of life in ancient rocks in the Pilbara, WA.

Two UNSW alumnae are building on their unique strengths as leaders in STEMM – a voyage that will lead them to Earth’s southernmost continent.

The 1912 death of Scott of the Antarctic and four companions has long been blamed on poor planning by Scott, but documents discovered by UNSW researcher Crhis Turney reveal a different story.

A discovery that microbes in Antarctica can scavenge hydrogen, carbon monoxide and carbon dioxide from the air to stay alive in such extreme conditions has implications for the search for life on other planets.

The Antarctic Treaty was signed 58 years ago today, protecting the continent for peace and science.

On February 11, 1913, the world woke to the headline “Death of Captain Scott. Lost with four comrades. The Pole reached. Disaster on the return”. A keenly anticipated, privately funded scientific venture “off the map” had turned to tragedy, writes Chris Turney.

The 1912 death of Scott of the Antarctic and four companions has long been blamed on poor planning by Scott, but documents discovered by a UNSW researcher reveal a different story – and a possible cover up.

New research has prompted warnings that melting Antarctic ice can trigger effects on the other side of the globe.

UNSW Sydney scientists studying microbes from some of the saltiest lakes in Antarctica have discovered a new way that the tiny organisms can share DNA that could help them grow and survive.
