    "description": "In November 2013, a large iceberg separated from the front of Antarctica’s Pine Island Glacier. It thus began a journey across Pine Island Bay, a basin of the Amundsen Sea. Since its separation, scientists have tracked the iceberg’s movement via satellite and with GPS sensors dropped onto the 21 mile long and 12 mile wide ice island. Its uneven, twisting motions are the result of different ocean currents, wind patterns and the shape of the seafloor, which likely stopped its progress a few times. The iceberg will eventually be swept up in the swift currents of the Southern Ocean, though it will be hard to track visually as Antarctica heads into winter darkness. Watch the video to see a time-lapse of the iceberg’s journey assembled from NASA satellite observations. || ",
