as calm as my internal organs. Question from: Michelle Jeffery to: Shackleton Bear dated: 22 Feb Question: what was your most exciting moment on your trip? Answer: Hi Michelle, Hmmm. That's a tricky question. I think the most exciting moment was today when I came over the hill and saw Ernest Shackleton's hut in front of me. I was named after him, and it was a real thrill to see the hut that he built 104 years ago. We saw lots of historic sites yesterday and today, and I loved it all. Question from: zoe hanna to: Shackleton Bear dated: 22 Feb Question: What is at the bottom of the Antarctic Ocean? Is it ice or sand? Answer: Hi Zoe, The geologists reckon that's a wonderful question, and they're very glad you asked it. Apparently it's sand, silt and lots of gravel. The gravel is really interesting (maybe not quite as interesting as the geologists think it is) because it falls on the sea floor from icebergs and ice shelves over millions of years. By taking samples of the gravel they can work out how much ice there was in Antarctica a long time ago.
