Scientists must venture to remote corners of the Antarctic to collect scientific specimens. Or, in some cases, they could just get samples through the Polar Rock Repository.

Geologists and other scientists will venture to remote places in Antarctica to collect rock specimens that may reveal clues about the continent's past geologic, or possibly Earth's climate history. Or they could just get samples through the Polar Rock Repository. Shipping is included.

Exploration of other planets and moons often begins in Antarctica. But a geologist who specializes in research of planetary surfaces using remote-sensing techniques is working in the opposite direction, applying his experience in studying Mars to learn about remote geology in Antarctica.

Oct 09 2014	Science / Ice and Snow Where Are They Now? One of the world's biggest break-up stories isn't in Hollywood. It's taking place around Antarctica. An iceberg that calved in March 2000 from the Ross Ice Shelf is continuing its slow disintegration in the Amery Sea, nearly halfway around the continent from where it started.
Oct 09 2014	Science / Oceans and Atmosphere Expansion Sea ice around Antarctica appears headed for another record year. NSIDC, partly funded by the National Science Foundation, reported that the five-day average for sea ice extent around the southernmost continent last month had already surpassed 20 million square kilometers for the first time in the modern satellite record.
Oct 09 2014	Science / The Biological World Self-Exile The latest study in a project that has been supported by the National Science Foundation suggests that Weddell seals in Antarctica can remain flexible even in the face of changing environmental conditions.
Oct 02 2014	Science / The Biological World Good Things in Small Packages It makes sense that life in extreme environments requires an organism to be "lean and mean" to survive. The recently sequenced genome of Antarctica's only endemic insect suggests that may apply genetically as well.
Oct 02 2014	Features / Life on the Ice Stormy Weather Stormy weather. It's been a familiar tune the last couple of months at McMurdo Station, where more than 62 inches of snow fell in August and windy conditions caused delays to several flights scheduled that month.
Sep 30 2014	Features / Operations New Chapter Begins Two aircraft carrying more than 160 people landed on a runway made of ice on the Ross Ice Shelf on Tuesday, kicking off the 2014-15 field season for the U.S. Antarctic Program.
Sep 25 2014	Science / Ice and Snow Surface Melt Newly published research on the geologic history of the Antarctic Peninsula, specifically an area where a large, floating ice shelf disintegrated in the early 2000s, indicates that the cataclysmic break-up was primarily a result of rising air temperatures and melting at the ice surface.
Sep 23 2014	Features / Operations Restricted Airspace They fly over outdoor concerts and battlefields. They come in all shapes and sizes Unmanned aerial vehicles are increasingly filling airspaces around the world. Antarctica is no exception.
Sep 18 2014	Science / The Biological World Life Among the Emperors From making the first measurements of the diving depth of an emperor penguin in the 1960s to tracking their colonies with satellites, Gerald Kooyman's long career studying the physiology and populations of marine vertebrates has made him one of the world's leading experts on Antarctica's iconic seabird.
Sep 11 2014	Science / Oceans and Atmosphere High-Water Mark The National Science Foundation (NSF) is providing support to help launch a $21 million interdisciplinary initiative involving 11 institutions across the United States to study the Southern Ocean around Antarctica.
Sep 11 2014	Science / The Biological World Split the Difference A sea star is a sea star is a sea star. Right? The answer to that question is not particularly straightforward, particularly when attempting to address species diversity around the entire Antarctic continent.
Sep 05 2014	Science / The Biological World A Mouthful The first study to characterize the feeding behavior of minke whales in the Antarctic has found that they can forage just below sea ice - the only such species to demonstrate that ability - and does so at a prodigious rate.
Sep 04 2014	Science / Earth Shutting the Door A new paper in the prestigious journal Nature suggests that 34 million years decreasing levels of carbon dioxide in the atmosphere initiated the glaciation of Antarctica, not the formation of the world's largest ocean current around the continent.
