What a great variety of shots from McMurdo you have given us. I really enjoyed the art pieces :) Sounds like you're getting a well-rounded look at life in Mac Town! I caught up on some of your journals and have some questions. First, the NASA balloons: How do they know where to retrieve the payloads-GPS? You said they travel around the world - from Antarctica? And, regarding the DOM, how will studying the DOM from the pristine conditions in the glacier help scientists study the the oceanic DOM? What exactly are they looking at? Keep up the excitement Sarah, you're doing great!! Happy New Year dear friend, Lollie
