MAYBE THE LIFE IN ANTARCTICA IS CHEAPER. WHAT SCIENTISTS SAY ? ANTARCTIC PERMAFROST STUDIES - IMPLICATION FOR BASIC SCIENCE WHY ANTARCTICA & WHY PERMAFROST?
The Earth Cryosphere represent a significant part of Biosphere, the Cryobiosphere, whose most inhabited part is permafrost - the most widespread natural depository of ancient viable organisms and the window into microbial life as it was before the impact of humans. Antarctica makes possible the observation of the results of natural cryopreservation of probably the oldest life on the Earth at the lowest ground temperatures and is of interest for geocryology, ecology, molecular paleontology, cryobiology and our understanding of temporal limits of the deep cold biosphere.
THE FUNDAMENTAL PROBLEM: HOW LONG THE LIFE MIGTH BE PRESERVED
APPLICATION FORGEOCRYOLOGY: DEVELOPMENT A BIOLOGICAL TIME-SCALE EXTENDING BACK THE DURATION OF THE PERMANENTLY FROZEN STATE IN SEDIMENTS
APPLICATION FOR ATMOSPHERIC SCIENCE, GLOBAL CLIMATE AND WATER CIRCULATION Is it possible that permafrost has existed in South Hemisphere greater than the duration of North Hemisphere by a factor of ten and that during most time of late Cenozoic our planet exist with only one cold Pole in South Hemisphere. Models for Astrobiology The main goal now is to find the oldest permafrost. The limiting age, if one exists, within the most ancient permafrost, where the viable organisms were no longer present, could be established as the age limit for life preservation at subzero temperatures. Of course, such expedition is expensive, but much more cheaper than to Mars
