The Earth’s southernmost continent is composed of land that is completely encircled by ocean and in most places, is covered by ½ mile of glacial ice. Sometimes called a polar desert, Antarctica is the most arid of all the continents, with very little snow falling each year. Scientists wonder what type of land forms can be identified beneath the ice, how glaciers work, and if movement of under-ice rivers

    Dinosaur Fossils in Antarctica Millions and millions of years ago the continents lay together as one super-continent known as Pangea. As time went on and the plates underneath the Earth began to separate, the continents land moved towards the poles where glaciation occurred. Glaciation is the process in which glaciers were formed during the ice age. Glaciation causes a drop in temperature which in turn causes water to freeze and form many layers of ice (http://palaeo.gly.bris.ac.uk/Palaeofiles/Permian/intro

    Global warming is one of the most tumultuous topics in today’s society. Some believe it is happening as we speak, while others question its very existence, So, is it real, or is merely a hoax? There is no one answer, but evidence does overwhelmingly support the former. Surely we have all heard this word at one time or another, but few individuals actually know its true definition. Justifiably, however, global warming is not that simply explained. In layman’s terms, it is the dramatic increase in

    Antarctica is the coldest place on earth, with temperatures at an average of -49°C, and it rarely ever gets above freezing. The reason why the Antarctic is so cold is because sunlight has to go through a thicker atmosphere to hit it as Earth is on an angle which also means the light rays are spread over a larger area than if they were hitting Antarctica directly. This means light is spread over a larger area thus not warming as much as it could. When sunlight does eventually meet Antarctica, a lot

    1. Introduction Marie Byrd Land (MBL) is a massif within West Antarctica that is of critical importance in understanding the evolution of the West Antarctic Rift System (WARS). Although the WARS is comparable in size other rift systems, it is poorly understood due to extensive ice cover (LeMasurier, 2008). MBL contains exposures which inform on the behavior of the WARS over time (Cande et al., 2000; Steinberger et al., 2004) and the potential for subglacial volcanism associated with the system to
