Antarctica as a Time Machine: Our Portal to Snowball Earth and Faraway Worlds

July 24, 2019 By



This month, we invited three scientists whose work is directly related to Antarctica to discuss the potential of this “continent for science”. Peter Roopnarine, Curator of Geology, Department of Invertebrate Zoology & Geology, Institute for Biodiversity Science and Sustainability,
California Academy of Sciences,  has studied ecosystems in extreme environments and how a planet emerges from a snowball to become a diverse biosphere. Tyler Mackey, Postdoctoral Fellow at Massachusetts Institute of Technology, focuses his research on habitats of the cryosphere and has dived in the lakes of the McMurdo Dry Valleys in Antarctica to study records of microbial activity. Ariel Waldman, citizen scientist and artist, just recently came back from an expedition in Antarctica, where she filmed microbes living within glaciers, under the sea ice, and in subglacial ponds. While there, she also shadowed various research teams, including a mission testing an autonomous underwater vehicle.

Beyond understanding the past life of our planet, Antarctica is a great platform to study life in an extreme environment. This month’s speakers are explorers who travel to the bottom of Earth to search for and characterize life with instruments that could one day explore Europa’s ocean. They’ll share their thoughts on Earth’s cryogenic past, when the surface was entirely or partially frozen, and discuss how their work in Antarctica is related to understanding its impact on the expansion of complex multicellular life.

    39:00 "Antarctica roughly the size of North America "
    Almost off by factor of 2!
    1. Asia 44,579,000 Sq. Km 30%
    2. Africa 30,065,000 Sq. Km 20.3%
    3. North America 24,256,000 Sq. Km 16.3%
    4. South America 17,819,000 Sq. Km 12.0%
    5. Antarctica 13,209,000 Sq. Km 8.9%
    6. Europe 9,938,000 Sq. Km 6.7%
    7. Australia (plus Oceania) 7,687,000 Sq. Km 5.2%
    It is significantly bigger than 48 states:

    Im 12mins in and theyre only talking about themselves. Its more like watching someones vacation photos. An artist "advises" nasa lol. Fuck these retards. She joined a microscopy club and trained herself. Thats 'women in science' in 2019. Lets have an entire month to celebrate her achievments

    You know the effect of trying to see a particle near the event horizon. With your on site observations ,bringing to the environment of Antarctica all the resources needed to stay “andOBSERVE”whitch brings HEAT

    what if Antarctica is earth?

    Scientists need artists more than they realise. And vice versa.
