This graphic is a summit ice core timeline depicting the phenomena that as we drill deeper ice cores, the ice gets older. The graphic compares this timeframe with major milestones in history. It is a concept developed by Zoe Courville and Dr. Mary Albert at Dartmouth University, in partnership with CRREL (Cold Regions Research and Engineering Laboratory).
The Transantarctic Mountains are an extreme example of rift flank uplift, extending over 3500 km across Antarctica and reaching elevations up to 4500 m (see map of the region). The mountain range was formed in the extensional environment associated with the breakup of Gondwanaland. Geological and geophysical work has shown that the Transantarctic Mountains developed along a long-lived lithospheric boundary
CTD Data plots from the Winter Sampling Expedition. CTD is an acronym for Conductivity-Temperature-Depth. It is a device that measures the salinity, temperature, depth in a vertical profile from the surface. The data comes from the Chukchi Sea.
The Norwegian explorer Roald Amundsen was the first person to reach the South Pole on December 14, 1911, following a race with the English explorer Robert Scott. Scott made it to the South Pole shortly after Amundsen but he and his four companions all died on the return journey.
They are not boots made from rabbit fur! Bunny Boots is the widely-used nickname for the Extreme Cold Vapor Barrier Boots, originally developed for the US military. The boots have become staple cold weather gear both in work and recreational environments in the Polar Regions. The nickname comes from the fact that the fur of the snowshoe hare, commonly found
Yes, there are southern lights. The aurora australis occurs around the southern magnetic pole, much as the aurora borealis (northern lights) occurs around the northern magnetic pole. Unlike the northern lights, which are seen across northern North America, Europe and Asia where a few million people live, the southern lights are seen only over Antarctica, where fewer people spend the
If Antarctica's ice sheets melted, an event that would take thousands of years to occur, the world's oceans would rise by approximately 200 feet (60 meters).
Ice fish are a unique group of fish found in Antarctica. Ice fish have evolved a variety of interesting physiological and biochemical adaptations that allow them to survive in the freezing, ice-laden waters of the Southern Ocean at temperatures that would freeze the blood of other fish. They do not have a swim bladder, and they spend much of their
