2011 Expedition Recon Mission

December 8th, 2010

During the week of December 6, 2010, Art Mortvedt, respected bush pilot, wilderness guide with over 24 years of polar expedition experience, and member of the Tawani Expedition Team, has traveled to the Antarctic on a special solo mission. The purpose for this “recon” mission is to best prepare for the follow up Tawani 2011 [...]

The ices of Earth’s polar regions and high mountains, once seen as sterile, harsh environments too poor in nutrients and liquid water to sustain life, are now known to harbor rich, complex microbial communities in the ice ecosystems of alpine and polar lakes, sea ice, glacier ice, and even ice of supercooled cloud droplets. The combination of dust, water, organic matter, sunlight, and life results in a tiny microcosm that derives liquid water and usable energy from the Sun, accumulations known as cryoconites. Cryoconite assemblages and their icy habitat have been proposed as a model system for understanding the challenges microbial life would face on Earth or other planets early in their evolution.

Hello Team,
The beginnings of a place to exchange ideas is now active.
Question each other and share info.
Avoid duplication of effort.
More to come.
