Scenes From Antarctica
Summer is returning to Antarctica and researcher teams from around the world are heading south for the (relatively) warm season. Among them are members of a Russian team that drilled into Lake Vostok last February. Vostok is a subglacial lake some 4,000 meters below the surface of the ice, and the plan is to send a robot down there this summer to collect water samples and sediments from the bottom. Research also continues at the South Pole Telescope, the IceCube Neutrino Observatory, and dozens of other locations around Antarctica. Gathered here are recent images of Antarctica, its environment, and some of the scientific work taking place there.

The Peltier Channel separates Doumer and Wiencke Islands Antarctica's Palmer Archipelago. It was named for Jean Peltier, a noted French physicist. Photo taken on May 17, 2012. (National Science Foundation/Janice O'Reilly)

Nacreous clouds, observed on January 6, 2011. These polar stratospheric clouds at 80,000 feet are the highest of all clouds. They only occur in the polar regions when the stratospheric temperature dips below 100 degrees below zero Fahrenheit (-73 C). They are also the site of chemical reactions that break down ozone in the upper atmosphere and contribute to the creation of the ozone hole above Antarctica.

A magnificent green aurora australis encompasses the South Pole Telescope (SPT) at Amundsen-Scott South Pole Station, on May 15, 2012. The SPT, designed to study the Cosmic Microwave background. is the largest telescope ever deployed at the South Pole. (National Science Foundation/Sven Lidstrom)

What appears to be dirty snow in this aerial photo of Cape Washington are actually groups of emperor penguins, seen on November 2, 2011. Dr. Paul Ponganis and his team (Scripps Institution of Oceanography) have been studying emperor colonies throughout the Ross Sea area for decades. (National Science Foundation/Dr. Paul Ponganis)

NOAA scientist Heather Moe walks upwind from Amundsen-Scott South Pole Station to collect clean air samples on February 7, 2012. The clean air samples are monitored for a variety of constituents such as carbon dioxide and ozone levels. (National Science Foundation/Ryan R. Neely III)
