The IR StCom meeting approved for an InterRidge Workshop/Third InterRidge Theoretical Institute in 2015 to focus on the first two themes in the “InterRidge Third Decadal Plan” with the title as “Magmatic and Tectonic Processes and Seabed Resources at Mid-Ocean Ridges”. It will be organized by InterRidge Office and will take place John Chen and Jiabiao Li in Peking University in Hangzhou, China on September 25-27, 2015. On January 1, 2013 the InterRidge Office moved from the National Oceanography Centre in Southampton (UK) to Peking University in Beijing (CHINA). We would like to take this opportunity to thank the previous InterRidge Office team, Bramley Murton (Chair), Jon Copley (Co-Chair) and Debbie Milton (Coordinator), for their successful efforts to lead the InterRidge community and activities over the past three years. Under their leadership the UK InterRidge Office has expended IR national memberships by adding Canada and Portugal to the Associate Member list and has started new initiative such as the cruise bursary IR Steering Committee meeting in Beijing scheme, which benefited dozens of young students China, Sep 2014, From left to right: Richard at the very beginning of their scientific career. Hobbs, Sung0Hyun Park, Nobukazu seama, Continuing the current policies, we will devote Jiabiao Li, John Chen, Kim Juniper, Marcia Maia, substantial effort and resources into nurturing Toshiya Funikura, Zengxi Ge collaboration within the IR community, particularly involving developing countries and countries of Third InterRidge Theoretical Institute on emerging economies. We strongly believe that the “Magmatic and Tectonic Processes and InterRidge should act as an active coordinator for Seabed Resources at Mid-Ocean Ridges” facilitating the exchange of scientists and their ideas Location: Hangzhou, China among the scientific community. Date: September 25-27, 2015 We had adopted a reform plan (attached in the The theoretical institute focuses on the first two following) for the new structure of the InterRidge themes of the InterRidge Third Decadal Plan with membership fees and privileges of each member the chairs and co-chairs for each of the two themes countries at the 2014 InterRidge Steering who will lead the scientific programs of the Committee in Beijing, China on 27-28 2014. It was a consensus at the IR StCom meeting that the theoretical institute which is organized by the reform of InterRidge is necessary to lead the InterRidge Office. Call for abstracts will be sent out InterRidge forward and to better implement the in Jan 2015. “third decadal plan” (http://interridge.org/ thirddecade) in order to meet the challenges at the Theme One: Magmatic and Tectonic Processes current funding situation at its member countries.
