Detecting Anomalous Life Swarms
The seas around Antarctica are alive, but that life is not evenly distributed everywhere. Vast regions of barren ocean are punctuated by oases of concentrated nutrients that create hotspots of biological activity.

Insects in the Extreme
Scientists are taking a close look at Antarctica's largest land animal. It's a small insect called the Antarctic midge, and they don't grow much bigger than a fingernail.

Facing the Ultimate Acid Test
Some of the Southern Ocean's smallest animals are facing big challenges. The once-exceedingly stable Southern Ocean around Antarctica is warming, and as it absorbs carbon dioxide from the atmosphere, it is also growing more acidic.

Masses of Mosses
As the continent warms, Antarctica is getting greener. Plants are taking hold where glaciers once covered the landscape. Moss in particular is sprouting up in new spots where it had been previously inhospitable. While moss isn't a new arrival to the continent, its spread could mean big changes for the ecosystems of Antarctica.

A Seal Grows In Antarctica
Weddell seals thrive in some of the coldest conditions on the planet, but scientists aren't quite sure why they don't freeze when they're first starting out.

Larvae La Vida Loca
As oceans warm around the world, the creatures that live in them are feeling the effects. In regions like the Southern Ocean surrounding Antarctica, which has been unchanged for millennia, researchers worry that even small fluctuations in water temperatures can have major effects on the marine ecosystem.

Stressed Out Fish?
Climate change is expected to be stressful on fish species worldwide: as the climate warms, so too will the oceans, putting a strain on creatures that depend on consistent water temperatures.

50 Years Of Weddell Seals
For a half a century, generations of researchers have studied various aspects of the life cycle of generations of Weddell seals around Antarctica's McMurdo Sound, making them some of the most closely studied mammals on the planet.

An Ecosystem Grows in Antarctica
Antarctica's native microorganisms are a hearty bunch, able to eke out a living on the planet's coldest, highest, driest, windiest and emptiest continent. But the region wasn't always quite as hospitable as it is today.

A World-Class Classroom At The Bottom Of The World
For early-career scientists, learning the ropes in Antarctica can mean donning actual safety lines and harnesses. This past austral summer, 20 students traveled to the National Science Foundation's McMurdo Station to conduct a range of experiments and learn first-hand what it's like to do research at the bottom of the world.

Ultraviolet Radiation Gives Microbes Mixed Messages
Ultraviolet rays from the sun may be disrupting the natural ecology of the waters of Antarctica's Southern Ocean. A research team, led by a scientist from the Woods Hole Oceanographic Institute, is taking a close look at the effects that excess UV radiation at the cellular level to see what it means for marine ecosystems and the regional food web.

Climate Change In The McMurdo Dry Valleys
The McMurdo Dry Valleys ecosystems are changing because of climate change. In a paper published in the journal Ecology in January researchers said they've tracked the decline of the microorganism living in the Dry Valleys' barren soils. More frequent extreme weather events are driving down the population of the nematode Scottnema lindsayae, a microscopic roundworm, which makes up about 90 percent of the species that live in the Dry Valleys.
