In contrast to previous years, the 2019-2020 webinar series highlights the cutting edge observations, data sets, and new quantitative methods that drive geodynamic modelling investigations. The webinar on April 16 will be presented by/Boris Kaus, Tobias Baumann, Georg Reuber, Anton Popov/(Johannes Gutenberg University of Mainz) on*Geodynamic inversion: Methods to link models with data & how that helps to obtain insights in the physics and rheology of the lithosphere*: / In order to link geodynamic forward models with geological and geophysical data, inverse modelling strategies are required. Here, we will discuss the basic principles behind the two main inversion approaches: Sampling-based (statistical) and gradient-based (deterministic) inversion. We will show the advantages and disadvantages of each approach related to geodynamical inverse problems. We will also explain the adjoint method, which is a particularly efficient way to compute the pointwise gradient of the misfit function with respect to model parameters. The gradients are not only useful for inversions but can also be employed to 1) automatically determine the key model parameters (and scaling laws) for a particular geodynamic simulation and 2) can be used to compute geodynamic sensitivity kernels that visually show where changes in the setup have a key impact, on, for example, the surface velocity. Finally, we will discuss a detailed example that shows how geodynamic inversion can be used to constrain the rheology of the lithosphere./ To join the webinar, please connect at :https://zoom.us/j/955605274 For additional information, please visithttps://geodynamics.org/cig/events/webinars/ As this webinar may be of interest to the broader Earth Sciences community, we encourage forwarding this announcement on to additional mailing lists or colleagues that may not normally receive CIG announcements. We look forward to your attendance and please do not hesitate to contact us if you have any questions!

Austermann and J. Suckale Message-ID: <7E19753F-FA4B-42B4-BE28-D49988E47704@ucdavis.edu> 17 April 2020 Dear Community, We are pleased to introduce the 2020-2021 CIG Distinguished Speakers: Asst. Prof. Jacqueline Austermann, Columbia University How mantle flow changes sea level and ice sheets Asst. Prof. Jenny Suckale, Stanford University To slide or to flow: Studying extremes in different natural systems sheds light on common physical processes The CIG Speakers Series seeks to promote computational modeling in geodynamics and related earth science disciplines. Speakers are drawn from a diverse pool of experts with exceptional capability to communicate the power of computation for understanding the dynamic forces that shape the surface and operate in the interior of our planet. Lectures are aimed at a broad scientific audience suitable for departmental or university colloquia series, and similar venues. Institutions with strong math and computational science departments or with diverse populations that are underrepresented in STEM are encouraged to apply Speakers will be available to meet with students and faculty during their visit. We encourage applications to host speakers from a wide range of disciplines and undergraduate institutions that increase the diversity of our community. Due to current travel restrictions, the program will be adjusted for the 2020-2021 academic year accordingly to meet the goals of the program and its participants. Interested in hosting speaker? More information can be found on our website: https://geodynamics.org/cig/events/speaker-series/ Apply before June 1, 2020 for full consideration by sending an inquiry to: speakers at geodynamics.org Please feel to forward and share this email with others.
