Hi Tim! Welcome back to the USA and Happy Holidays to you and your family! Thank you for sharing so much information with us! It was great to hear directly from the engineers and see the technologies being used in Antarctica. Here are a few questions from my students when you have time: 1) Since Antartica is so volcanic, is it possible to use geothermal energy for heat? Why or why not? 2) What types of technology are used to keep you warm? (What kinds of insulators are used in the jackets or in the tents?) 3) What would happen if someone got too cold while out in the field? 4) Have you seen any whales? If so, what kind? 5) Why don't penguins feet freeze?
