Antarctic ice shivers from distant earthquakes

Science | Earth

Antarctica is the most remote continent on Earth, but new research shows it is still connected to what happens in the rest of the world. A new study finds large earthquakes can cause ice on the slopes of Antarctica's Mt. Erebus to quiver and vibrate, even when the quake happens thousands of miles away.

Meet the Penguin Misfits

Science | The Biological World

Looks are important for Adelie penguins, but they may not be as critical for breeding as biologists previously thought. New research shows Adelie penguins with unusual coloring still manage to breed successfully, contrary to what biologists had predicted.

Coldest, Driest, Saltiest Antarctic Soils Might Be Inhospitable To Life

Science | The Biological World

Some Antarctic soils might be the only environments on Earth microbes can't colonize, a finding that goes against scientists' expectations of our planet's habitability. Most scientists assume microbes can inhabit every environment on Earth, given enough time, but new research finds that some of the coldest, saltiest, and driest soils in the Transantarctic Mountains show no signs of viable microbial life.

Warm Ocean Water is Eroding Thwaites Ice Shelf From Below

Science | Ice and Snow

Scientists got their first glimpse at the ocean conditions surrounding the Thwaites Ice Shelf in 2019, and recently published results are worrisome for the rapidly melting ice shelf and the glacier behind it.

Tapping Erebus's Power

Science | Earth

The heat given off by Antarctica's Mount Erebus could help power instruments monitoring the volcano, giving scientists a way to study Erebus's lava lake during the long polar night for the first time. Researchers have found a way to harness the heat from the magma underneath Erebus and turn it into electricity that can power scientific instruments.

Thwaites Glacier - Future

Science | Ice and Snow

The massive Thwaites Glacier on the coast of West Antarctica is falling to pieces because of climate change. Shifting ocean currents are bringing warm sea water up under its vulnerable underside, melting out the ice at its base and accelerating its movement into the ocean.

Thwaites Glacier - Present

Science | Ice and Snow

Thwaites Glacier is melting fast because of climate change, causing sea levels to rise the world over. Of all the world's glaciers, it's the one that scientists are most worried that a catastrophic collapse could happen quickly and affect coastal regions everywhere.

Thwaites Glacier - Past

Science | Ice and Snow

Antarctica's massive Thwaites Glacier is melting because of climate change, and if it collapses completely, could add about two feet to global sea level. Glaciologists are tracking it with alarm, as Thwaites has lost a tremendous amount of mass over recent decades, but its remote location in West Antarctica makes getting an up-close look at it extremely difficult.
