SETI Institute Scientist Dale Andersen featured in the Explorers Journal

Dale Andersen's work at the Queen Maud Land, Antarctica is featured in the Winter 2013/2014 issue of the Explorers Journal which offers firsthand reporting from those pushing the limits of knowledge and human endurance. In Diving for Science in Antarctica, Dale details his discovery and observation of living microbial mats that form the same morphological structures that one sees in the fossil record dating back 3.45 billion years. These mats inform us about those early ecosystems and let us ask questions about why and how they formed. "The interesting thing about Lake Untersee is that as far as we know, it's the only location on Earth where one can find a modern analog of the large conical stromatolites growing, perhaps as they did billions of years ago" notes Dale.

Dale, senior research scientist at the Carl Sagan Center of the SETI Institute, has an interest in locating and understanding environments where physical and chemical conditions approach or exceed the tolerance for life as we know it. He has been involved with NASA's astrobiology programs since the 1980s and has made more than 600 dives beneath the perennially ice-covered lakes and oceans in the Arctic and Antarctic.
