URL: From sergei at cp.dias.ie Mon Dec 23 04:21:02 2019 From: sergei at cp.dias.ie (Sergei Lebedev) Date: Sun, 22 Dec 2019 17:21:02 +0000 Subject: [Geodynamics] Postdoctoral Position in Geothermics, Geophysical-Petrological Modelling and Seismology Message-ID: <5d01055ceec713e8ec5027103796e704@cp.dias.ie> Dear Colleagues, The Dublin Institute for Advanced Studies invites applications for a 2-year postdoctoral position in seismology and integrated geophysical-petrological modelling. The position is at the Geophysics Section, DIAS, and is funded by the project DIG. DIG (De-risking Ireland?s Geothermal potential) will explore the potential for low-enthalpy geothermal energy on the island of Ireland. It will integrate multi-disciplinary, multi-scale geophysical, geological and geochemical data by means of joint analysis, interpretation, modelling and inversion. The goal of this postdoctoral project?one of the 5 under DIG?is to build a 3D thermal model and determine the regional geothermal gradient across the island of Ireland. A very large, recently assembled set of broadband, surface-wave measurements is one key component of the dataset. It can constrain crustal structure and the temperature and thickness of the mantle lithosphere. Other essential information will come from the surface heat flow, controlled-source seismic profiles, magnetotellurics, magnetic and gravity anomalies, and measurements of crustal radiogenic heat production and thermal conductivity. Thermodynamic petrological modelling and inversion of the data will be performed using the LitMod software tools (https://protect-au.mimecast.com/s/xzJMCnxyErCPjpQ2u9Jiem?domain=github.com) for integrated modelling and inversion, with further methodological developments, as needed, in the course of this project. Duration: 2 years. Salary: ?37,874-45,041, depending on experience and qualifications. Start date: as soon as possible. Qualifications: a PhD in geophysics or a related field is required. Substantial computing and programming experience and a good command of English are essential. A publication record commensurate with career stage is expected. Experience in the seismic imaging of the lithosphere, petrological modelling and inversion, or geothermal modelling is desirable. To apply: e-mail a complete academic CV, including a list of publications, a statement of research interests, and the names and contact details of 3 academic referees to Dr. Javier Fullea (jfullea at cp.dias.ie) and Dr. Sergei Lebedev (sergei at cp.dias.ie), with "DIG postdoctoral position" in the subject line. Consideration of the applications will begin immediately and continue until the position is filled. For additional information on the project, please contact Javier Fullea (jfullea at cp.dias.ie) or Sergei Lebedev (sergei at cp.dias.ie). DIAS is committed to gender balance, inclusion and diversity. This project is funded by the Sustainable Energy Authority of Ireland under the SEAI Research, Development & Demonstration Funding Programme 2019 (grant number 19/RDD/522) and by the Geological Survey Ireland.

(2019) model Message-ID: <05181BF8-E0FD-4877-90FB-AD2D4EEF5B54@sydney.edu.au> Dear GPlates users, friends and colleagues, As many of you wind down for a well-deserved break, the GPlates team at Sydney has been working hard in Santa?s workshop to send out an update on our global plate reconstructions. There are updates to the relative and absolute plate motions in the Muller et al. (2019) reconstructions, and v2.0 of the model (including GPlates files, age-grids, global and regional animations, stretching factor grids, etc.) are available to download from here: https://protect-au.mimecast.com/s/sy7vC2xZYvCBvKLpCnhcoq?domain=earthbyte.org The Muller et al. (2019) v2.0 release notes are below. Relative and absolute plate motions * Full synchronisation of east Asia reconstructions of Young et al. (2018) from 250 to 130 Ma, including the closure of the Mongol-Okhotsk Ocean * Improved kinematics of the back-arc basin history along western North America (250 to 180 Ma) so that the seafloor spreading isochrons are consistent with the implied plate motions * Pacific absolute plate motion fixes following Torsvik et al. (2019) * Absolute optimised frame, with simplified hierarchy at 5 Myr intervals with optimisation weighting parameters of * 0-80 Ma: TR=1, NR=1, HS=1; * 80-170 Ma: TR=1, NR=0.5; * 170-250 Ma: TR=1, NR=0.2 * Where TR=trench migration optimisation, NR=net rotation optimisation and HS=hotspot track fitting, in an optimisation framework as described in Tetley et al. (2019), with numbers referring to relative weights of the optimisation parameters. These parameters were iteratively determined to provide the most optimal absolute plate motion model, given the relative plate motion revisions listed above. Interpolation of deformation grids * Using nearneighbor rather than spherical interpolation (removing areas that have had no deformation) * Applying rigid blocks within deformed regions (e.g. Tarim craton, Khorat platform, etc.), as well as oceanic age-grid, as masks to remove anomalous areas of extrapolation * Previous versions had a tiny amount of negative values in stretching factors, but these grids are now clipped to values above zero References M?ller, R.
