Study: Glacial Lakes Appearing in Antarctica

Antarctica is home to Earth’s largest ice mass, which unlike the Arctic remains frozen year round. But a new satellite-based study in the journal Geophysical Research Letters shows that atop the coastal Langhovde Glacier in East Antarctica’s Dronning Maud Land, large numbers of meltwater lakes have been forming. The study suggests that the lakes—nearly 8,000…

Natural Fluctuations Responsible, in Part, for Antarctica Ice Growth

Natural fluctuations specifically related to the Interdecadal Pacific Oscillation (IPO) are responsible for the increased growth of Antarctic sea ice, according to a new study in the journal Nature Geoscience. A negative shift in the IPO has caused cooler-than-average sea surface temperatures in the Eastern Pacific, allowing Antarctic sea ice to expand since 2000. “The…

Leopard Seal vs. Leopard Seal—Underwater Food Fight

We know that leopard seals are large, formidable predators, but exactly what they’re doing below the waterline has long remained a mystery. But now, thanks to National Geographic grantee Douglas Krause, we’re getting an underwater glimpse into leopard seals’ carnivorous lives—and the seal-on-seal battles are a sight to behold.

Tagging Adorable, Nasty Little Penguins: #bestjobever

The world has had a love affair with penguins for some time now. Their tuxedo-colored feathers, waddling walk, and awkward mannerisms make them easy to adore. But get too close to penguins—chinstrap penguins in particular—and your endearing perception of these birds may be tested, given their penchant for projectile pooping and beating each other up.

This blog entry spotlights some of the exciting work our grantees are doing with support from the LEX-NG Fund. A man is poised with a…

A Plea for Adélie (Penguins)

Last week in an obscure stone building in Hobart Tasmania, representatives from 24 nations plus the European Union, sat in stiff dark suits around a large table, making decisions that will determine the fate of one of our great global commons, the Southern Ocean. They discussed proposals for expansive marine protected areas, including in the…

May 4, 2014: Driving to the World’s Coldest Cities and Cracking the Humor Code

The winter of 2014 was long and cold in many parts of North America. But even the most frigid midwestern temperatures would be considered mild to Oymyakon, Russia’s 472 residents. One of the candidates for the “Coldest Town in the World,” Felicity Aston visited the Siberian hamlet in the middle of winter to learn how its residents deal with sustained temperatures of -76 degrees Fahrenheit. On her 18,000 mile “Pole of Cold” drive from London to Europe and Asia’s coldest places, Aston learned that the residents love winter, because it often provides them with their livelihood, it connects them with nearby towns by letting them drive over frozen lakes and rivers. She also gives tips on how to get a car to start when the mercury dips nearly 100 degrees below freezing.
