A massive ocean lies underneath a shell of ice on Jupiter’s moon Europa. NASA has funded a seismometer being developed by Arizona State University researchers that would allow them to listen to what is underneath the ice to determine things like how thick the ice is, whether it holds pockets of water, and how often that water could spill through the surface through cracks in the ice shell. ASU seismologist Edward Garnero will tell us more about what’s being dubbed a “planetary stethoscope.”
Earlier this month, the UN Intergovernmental Panel on Climate Change issued a warning on climate change that found that emissions of greenhouse gases are the highest in history, driven largely by economic and population growth. The report also found that the atmosphere and ocean have warmed and sea levels have risen. Professor James Anderson of Arizona State University’s Global Institute on Sustainability will talk about the report.
Professor Ariel Anbar of ASU’s School of Earth and Space Exploration talks discusses how ASU and the University of Cincinnati are planning to use a new geo-chemical technique to study ocean chemistry in an effort to study a mass extinction that hit the Earth 250-million years ago.
