The explorer led three British expeditions to the Antarctic, and he was in the early stages of a fourth when he died of a heart attack aboard the Quest near the Falkland Islands.
New research on Antarctica's Thwaites Glacier could reshape sea-level rise predictions
At 80 miles across, Thwaites is the world's widest glacier. It has been nicknamed the "Doomsday Glacier" for the catastrophic effects its thawing could have on global sea-level rise.
An Australian who fell ill at a remote Antarctic base is rescued, authorities say
The man who fell ill is expected to arrive in Australia next week. Until then, he will be cared for in an icebreaker's specially equipped medical facility.

It's the middle of the winter in Antarctica, when the ocean around the continent freezes. But this year there's less sea ice than ever recorded.
How disappearing ice in Antarctica threatens the U.S.
Galveston, Texas has some of the fastest sea level rise in the world. To protect the city, engineers need to know how fast ice in West Antarctica will melt. Scientists are racing to figure it out.
Humans must limit warming to avoid climate tipping points, new study finds
The Earth has already warmed more than 1 degree Celsius. New research suggests that above 1.5 degrees, massive ice melt, ocean current disruptions and coral die-offs are likely.
A previously stable ice shelf, the size of New York City, collapses in Antarctica
The collapse, captured by satellite images, occurred in East Antarctica — an area long thought to be stable and not hit much by climate change, scientists say.
Ernest Shackleton's ship Endurance, lost since 1915, is found off Antarctica
An expedition went where few have ever gone to locate the remnants of a ship that became trapped in the ice 106 years ago, dashing the famed explorer's ambitious mission to cross Antarctica.
Soot is accelerating snow melt in popular parts of Antarctica, a study finds
Arctic communities have long been plagued by soot that drives snow melt and respiratory disease. Now, humans are making their mark in Antarctica.
