Advancements in Understanding Seafloor Volcanism and Life: Axial Seamount  - A Wired Submarine Volcano Observatory

Session ID#: 76519

Session Description:
This session will bring together an interdisciplinary community of Earth and Space scientists focused on Axial Seamount, which hosts the most advanced submarine volcanic observatory on Earth – the NSF-funded OOI Cabled Array. Since 2014, data from a diverse array of instruments have been streaming live to a global audience of users. In 2015, the array of geophysical, biological, and chemical sensors captured an underwater eruption as it was happening for the first time.  Since then activity has been ramping up, suggesting another eruption within the next few years. This session will focus on new results and will look forward, with implications for understanding the dynamics of submarine volcanism, which accounts for >70% of the volcanism on Earth, and its connection to chemosynthetic life. Invited talks will include undergraduates and early career scientists and uses of the observatory focused on Biospheres in Ocean Worlds, a program now funded by NASA.
