On behalf of the US InterRidge Selection Committee: Ross Parnell-Turner (Scripps Institution of Oceanography), Zach Eilon (UC Santa Barbara), Laurent Montesi (University of Maryland), Joyce Sim (Georgia Tech), Jessica Warren (University of Delaware), we are happy to announce that the U.S. is now once again a ‘Regular’ member of InterRidge. InterRidge is an international, non-profit organization supported by fee-paying member nations, concerned with promoting all aspects of ocean floor research (its study, use, and protection), administered by a rotating office that is currently hosted by Korea. Membership of InterRidge will allow U.S. scientists to more easily identify research opportunities and collaborations with international partners, participate in working groups, and gain access to support for spare berths on cruises and student fellowships. We encourage members of the US Ridge community (broadly defined, including but not limited to geologists, geophysicists, marine chemists, biologists, and physical oceanographers) to fill out this short form to join the US InterRidge mailing list and indicate your interest in serving on the US InterRidge Steering Committee by April 1, 2022.
