We learned about this and more at the fourth annual Polar Day, hosted by Penn State’s Polar Center on Tuesday, March 22. A variety of activities and presentations throughout the day highlighted several aspects of polar exploration and research. Presentations ranged from an ROV — remotely operated vehicle — demonstration to photography to musical interpretations of data from polar regions.
