Artist Karen Romano Young explores some of the secrets of the Antarctic ice sheet and how science helps reveal them.

Artist Karen Romano Young explains through SciArt why tiny krill are a big deal for Antarctic food webs (and penguins, seals, orcas–and scientists).

Global warming has affected the entire planet’s surface, except for one particular area of the ocean, which until 2015 had bucked the trend. A research team has now unraveled what was going on.

A new study in the AGU journal Geophysical Research Letters modeled how much faster Thwaites, one of West Antarctica’s largest and fastest-retreating glaciers, would retreat in the absence of its ice shelf — the part of the glacier that floats on top of the sea, supporting the thicker ice behind…“Worst-case scenario, it is going to be gone in less than a century. But it may also take much longer.”

Dr. Frankenstein aside, science doesn’t intend to be spooky. Sometimes it just comes out that way. Scientific endeavors have revealed some eerie places and a symphony of scary sounds from all over the planet — everything from bellowing sand dunes and whistling lightning, to groaning ice shelves of Antarctica. We got them here in our 2019 Halloween playlist.

Researchers at NYU Abu Dhabi have discovered how the Maud-Rise Polynya that was initially spotted in Antarctica in 1974, reappeared in September 2017 at the same location.

Shallow bodies of water, on the order of 10 centimeters deep, could have held high concentrations of what many scientists believe to be a key ingredient for jump-starting life on Earth: nitrogen.

Today at 2 pm EST, AGU is holding a press conference titled “Penguins! From space” at Fall Meeting 2018. New research will be discussed about how studying satellite images of penguin poop, or guano, in west Antarctica can give scientists an idea of how penguin diets changed over decades or centuries. To help you get a picture of the penguin research, check out this beautiful comic, created by JoAnna Wendel.

New research links the mummified remains of penguin chicks in Antarctica to two massive weather-related calamities that could become more commonplace with climate change.

More than 100 oceanic floats are now diving and drifting in the Southern Ocean around Antarctica during the peak of winter. These instruments are gathering data from a place and season that remains very poorly studied, despite its important role in regulating the global climate.

The most comprehensive magnetic map of Antarctica ever produced was published online this week in a new study in Geophysical Research Letters, a journal of the American Geophysical Union.

A group of over 80 researchers published some stunning data in Nature today, and it shows the ice loss in Antarctica has tripled since 1992. The loss of ice rose sea levels worldwide an average of 7.6 mm and rate of ice loss in West Antarctica has tripled since 1992! The paper was one of several in this issue of Nature and it’s worth grabbing a copy of the entire …

Extensive ice-penetrating radar data reveal three vast valleys under glaciers in West Antarctica. These valleys could be important in the future as they help to channel the flow of ice from the center of the continent towards the coast.

Even though the sun does not shine in Antarctica in winter, in some places snow on the glaciers can melt. The cause: warm wind.

A video has gone viral on Youtube, apparently showing a crashed UFO on South Georgia,. In reality it shows the runout path of an elongate boulder that was a part of landslide from a permafrost affected mountain

An international team of scientists, led by British Antarctic Survey (BAS), has produced a new map showing how much heat from the Earth’s interior is reaching the base of the Antarctic Ice Sheet.

By Sarah Sams MAGIC-DML is an international collaboration focused on mapping, measuring, and modeling Antarctic geomorphology and ice change in Dronning Maud Land. The team has one austral field season under its belt and is in preparation for another this coming December through February. The week of October 2-8 was dedicated to preparing for the upcoming field season and reviewing progress from the previous one. The week began with a three-day …

In a new study, scientists have discovered huge canyons cutting through the underbelly of Antarctica’s ice shelves, meaning they may be more fragile than previously thought. Thanks to the CryoSat and Sentinel-1 missions, new light is being shed on this hidden world.

While winter sea ice in the Arctic is declining so dramatically that ships can now navigate those waters without any icebreaker escort, the scene in the Southern Hemisphere is very different. Sea ice area around Antarctica has actually increased slightly in winter — that is, until last year. A new study shows the lack of Antarctic sea ice in 2016 was in part due to a unique one-two punch from atmospheric conditions both in the tropical Pacific Ocean and around the South Pole.

Antarctic sea ice – frozen ocean water that rings the southernmost continent – has grown over the past few decades but declined sharply in late 2016. By March of 2017 – the end of the Southern Hemisphere’s summer – Antarctic sea ice had reached its lowest area since records began in 1978. Puzzled scientists wanted to know why.
