You are cordially invited to join us ..... "Reconstructing Paleoenvironments Using Synchrotron X-ray Spectroscopy of Mineral Archives" Gavin Piccione Brown University JUNE 25, 13:30(EDT) To register for virtual attendance: https://bnl.zoomgov.com/meeting/register/oVMiZQb7TtWxX2_m1RFTxg Abstract: The subglacial environment beneath ice sheets plays a critical but poorly understood role in Earth's climate and biogeochemical cycles, generating nutrients that fuel polar ocean ecosystems and offering analogs for habitable environments on icy worlds. In this talk, I show how synchrotron-based X-ray spectroscopy, combined with isotopic and elemental data from sedimentary rocks, can reconstruct the chemical evolution of subglacial fluids through time. This integrated geochemical approach reveals how these hidden environments respond to climate change, providing time-resolved insights into the ecological and geological processes operating beneath the ice. ================= Vivian Stojanoff, PhD Education, Training, Outreach User Program p 1(631) 344 8375 e [email protected]<mailto:[email protected]> w https://www.bnl.gov/ps/lifesciences/<https://www.bnl.gov/ps/lsbr/> Address: Center for Biomolecular Structure National Synchrotron Light Source II Building 745 Brookhaven National Laboratory Upton NY 11973 ######################################################################## To unsubscribe from the CCP4BB list, click the following link: https://www.jiscmail.ac.uk/cgi-bin/WA-JISC.exe?SUBED1=CCP4BB&A=1 This message was issued to members of www.jiscmail.ac.uk/CCP4BB, a mailing list hosted by www.jiscmail.ac.uk, terms & conditions are available at https://www.jiscmail.ac.uk/policyandsecurity/
