Nacreous Clouds

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.

Nacreous Clouds Above Ross Island

This image shows nacreous clouds above Ross Island, Antarctica. 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. 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.

Antarctic Meteorite

This is a thin section of a meteorite from the Miller Range, Antarctica. Field researchers in Antarctica have returned with more than 17,500 meteorites over the 30-plus years that the extraterrestrial material has been collected from the frozen continent. Yet meteorite science is still in its infancy, and the collected rocks still hold plenty of surprises that could shape our understanding of the solar system, according to scientists involved in the search and characterization of the…

South Pole Telescope At Night

The 10-meter South Pole Telescope and the BICEP (Background Imaging of Cosmic Extragalactic Polarization) Telescope at Amundsen-Scott South Pole Station, against the night sky with the Milky Way. The red lights are used to minimize light pollution, but still enable people to see while walking to and from the facility during the six months of darkness. Both of these telescopes collect data on cosmic microwave background radiation and black matter.

Antarctic Researchers Study Deep-Ice Cores

In 2009, U.S researchers conducted the second field season of a deep-ice coring project in West Antarctica in order to study climate, ice sheet history and cryobiology. This project is collecting a deep-ice core from the West Antarctic Ice Sheet (WAIS) and integrates approximately 20 separate projects that will analyze the ice. Ultimately, the WAIS Divide project will develop climate records with an absolute, annual-layer-counted chronology of the last 40,000 years. Future lower temporal…

Leopard Seal On The Prowl

Pictured at left is a leopard seal on the prowl at Cape Washington, Ross Island. Leopard seals are the second largest species of seal in the Antarctic (after the southern elephant seal). They are most common in the Southern Hemisphere along the coast of Antarctica and on most sub-Antarctic islands. During the summer months, the seals hunt among the pack ice surrounding the continent, spending almost all of their time in the water.
