From kasey at iris.edu Wed Feb 14 15:28:05 2018 From: kasey at iris.edu (Kasey Aderhold) Date: Wed, 14 Feb 2018 18:28:05 -0500 Subject: [OBSIPtec] Announcements for Seafloor Geophysical Observations Session at JpGU2018 and Marine Geophysics Post Doc Opportunity at IPGP Message-ID: <6953e2b0-5032-bcd6-8111-61b68f47208b@iris.edu> *Seafloor **Geophysical**Observations Session at the Japan Geoscience Union Meeting:* Dear colleagues, I would like to announce that the submission of abstracts has started for the following JpGU-EGU-AGU joint session in the 2018 JpGU meeting. The session title is "Probing the Earth's interior with geophysical observation on seafloor" (the session ID is S-IT24). The submission deadline is 8:00 (UTC) on Feb 19. If you are interested in the session, please access the JpGU2018 home page as bellow. www.jpgu.org/meeting_e2018/ Submission to the session "The lithosphere and the asthenosphere" (S-IT28) convened by Hitoshi Kawakatsu et al. is also open until the same deadline on Feb. 19. We are looking forward to seeing you there. =========Session scope of S-IT24=========================== Probing the Earth's interior with geophysical observation on seafloor Most important sites for plate tectonics and mantle dynamics studies (e.g., subduction zones, spreading ridges, and hot spots) are located in oceanic regions. The coverage of seismic stations is concentrated in land areas, which cover only one-third of Earth's surface. Since 1990s, technology for seafloor geophysical instruments to explore deep earth structure have been advanced, such as broadband ocean bottom seismographs (BBOBSs), ocean bottom electro-magnetometers (OBEMs), and pressure gauge, because observation network in oceanic regions is essential for major breakthroughs in Earth sciences. Technical advance in the instruments including cabled realtime seafloor networks have made the seafloor observation more common and reliable, which promotes a number of seafloor observations, both temporary and permanent networks, in the last decade. We call for papers on recent scientific results from such observation projects, including those on crust and mantle structure beneath subduction zones, hot spots, Large Igneous Provinces, and spreading ridges. Technical advances for observation in oceanic regions, including seafloor instruments and drifting float,? proposals and plans for innovative observations are also welcome. Invited speakers: G Barruol (IPGP), C Rychert (U Southermpton), R Evans (WHOI) Conveners: D Suetsugu, G Barruol, H Kawakatsu, D Wiens ==================================== *Marine Geophysics Post Doctoral Opportunity at**Institut de Physique du Globe Paris:* Applications are invited for A Post Doctoral position in Marine Geophysics at Institut de Physique du Globe Paris (IPGP) * * The Institut de Physique du Globe de Paris has an opening for 1-2 post-doctoral positions to carry out research in marine geophysics, initially for 1.5 years with a possibility of extension up to 3 years. The project is funded by the European Research Council to acquire ultra-deep seismic reflection and refraction data across the Atlantic Ocean, starting from the Mid-Atlantic Ridge to the African Continental margin, over the oceanic lithosphere of zero age up to 75 Ma. The scientific objective of the experiment is to characterise the nature of the oceanic lithosphere down to the base of the lithosphere-asthenosphere boundary (LAB), and develop a model of the evolution of oceanic lithosphere as it cools away from the ridge axis. In 2015, ultra-deep seismic reflection data (30 s record length) using a 12 km multi-component streamer were acquired over the Mid-Atlantic Ridge extending up to 75 Ma and also crossing the great equatorial fracture zones (Chain, Romanche and St Paul) in the Atlantic Ocean. In 2017, an 1100 km long coincident refraction data using 71 ocean bottom seismometer were acquired along the flow line, and in 2018 another refraction data will be acquired across fracture zones. The post-doctoral fellow will take an active role in acquisition, processing and interpretation of these unique data and integration with other geophysical and petrological results and carryout numerical modeling. The candidate should have completed a PhD degree in geophysics with experience in analyses of reflection and/or refraction data and interested in marine geophysical data acquisition and processing to address fundamental scientific problems. *Application Procedure: *Email a CV with a letter of application to Ms Marie Dominique Rocheron (rocheron at ipgp.fr ), Institut de Physique du Globe de Paris, 1 rue Jussieu, 75238 Paris France. Please request two referees to email recommendation letters directly to the above address. Deadline for application is February 28, 2018.
