The primary explanations for the young crater age of the surface of Venus are progressive volcanic resurfacing and a period of mobile‐lid tectonics. However, model results also must explain the offset in the center of mass (CM) of the planet and its geometrical center (CF) as well as a lack of a geodynamo. King (2018) used CitcomS 3.3.2 to study the role of initial conditions, mantle potential temperature, and core potential temperature on Venus surface mobility. The results show that while mobile lid tectonics produces progressive resurfacing, it overpredicts the CM-CF offset. In addition, the resulting heat flow would also be sufficient to power a core dynamo which Venus lacks. Hence, Venus youthful surface is inconsistent with catastrophic overturn. [King, 2018 ] [highlight ] TACC/Frontera The Texas Advanced Computing Center (TACC) at The University of Texas at Austin will begin operations of Fronterra in 2019. The NSF-funded supercomputer will be the fastest at any U.S. university and among the most powerful in the world. Anticipated early projects on Frontera include solid Earth geodynamics in partnership with CIG scientists, analyses of particle collisions from the Large Hadron Collider, global climate modeling, improved hurricane forecasting and multi-messenger astronomy. World- 17 researcher-developers gathered in Boulder, Colorado 16-19 September 2018 for the first Rayleigh Hackathon. Many thanks to Nick Featherstone and Jon Aurnou for leading this project and event.

[link ] CTSP Whitepaper The Coupling of Tectonics and Surface Processes (CTSP) workshop took place from 25-27 April 2018 at the University of Colorado Boulder. At total of 95 participants, including the organizing committee attended on site and up to 54 remote participants attended by video conference. The workshop was structured around two days of talks, breakout sessions, and posters. Breakout sessions focused on the key questions, opportunities, and challenges, for both the individual tectonics and surface processes communities, as well as across communities. The discussions covered a range of topics, including: How can strain predictions from a tectonic model be translated to erodibility in a landscape evolution model? Do tectonic models need 2D topographic information, or is collapsing topography into 1D sufficient? At what time scales should models be coupled? A full summary is available [whitepaper ].

Thermo-mechanical models have proven to be valuable tools to understand the processes involved during deformation of the lithosphere.

In this webinar we will briefly give an overview of why we think surface processes must be taken into account, how it can be done using numerical models and what are the remaining challenges.

The purpose of the ShakeAlert System is to reduce the impact of earthquakes and save lives and property by providing alerts (ShakeAlerts) that are transmitted to the public via mass notification technologies and more detailed data streams to institutional users and commercial service providers to trigger automated user-specific protective actions. The ShakeAlert System is built on the foundation of the sensor networks and data processing infrastructure of the USGS-led Advanced National Seismic System (ANSS) and requires fast, reliable telemetry to deliver sensor data to processing centers. The ShakeAlert data processing infrastructure includes redundant servers that are geographically distributed at the monitoring centers of tier 1 ANSS seismic networks in Seattle, Washington, as well as Menlo Park, Berkeley, and Pasadena in California. To have the greatest benefit, ShakeAlerts will be delivered to institutional users and individuals by all practical pathways. ShakeAlerts are useless if people do not know how to respond to them. Although the alerts will include instructions about what to do (e.g. drop, cover, and hold on), they will be more effective if people have been trained in advance. Messages about ShakeAlert’s capabilities, limitations, and benefits should be integrated with existing earthquake education programs, including State-run programs. ShakeAlert’s Joint Committee for Communication, Education, and Outreach coordinates with both public and private partners and stakeholders through various partnerships and agreements to accomplish consistent and ongoing public education and training. The estimated cost of completing the computing infra­structure and sensor networks for ShakeAlert is $39.4 million. The annual operation and maintenance cost of the completed system is estimated to be $28.6 million per year.

URL: From DGEIST at nsf.gov Wed Nov 21 05:42:47 2018 From: DGEIST at nsf.gov (Geist, Dennis) Date: Wed, 21 Nov 2018 13:42:47 +0000 Subject: [CIG-ALL] New program at NSF Message-ID: <0621DBB5-C4DB-4209-B0AE-371B4291459B@contoso.com> A solicitation has been posted for a new program from the Division of Earth Sciences “Frontier Research in the Earth Sciences (FRES)”. FRES supersedes the former “Integrated Earth Systems (IES)” program. In addition to substantive changes in the goals of the program and eligible projects, the proposed budget for the new program is larger. The target date for submission of proposals is February 20, 2019. The announcement of the program and link to the solicitation may be found at: https://www.nsf.gov/funding/pgm_summ.jsp?pims_id=504833 A webinar will be held on Wednesday, December 5 at 2 pm, with a brief overview of the program and the opportunity to ask questions. Please email dgeist at nsf.gov by 5 pm on December 3 to enroll in the webinar. SYNOPSIS The FRES program will support research in Earth systems from its core through the critical zone. The project may focus on all or part of the surface, continental lithospheric, and deeper Earth systems over the entire range of temporal and spatial scales. FRES projects will typically have a larger scientific scope and budget than those considered for funding by core programs in the Division of Earth Sciences (EAR). FRES projects may be interdisciplinary studies that do not fit well within the core programs or cannot be routinely managed by sharing between core programs. Innovative proposals within a single area with results that will have broad relevance to Earth Science research are also encouraged. Investigations may employ any combination of field, laboratory, and computational studies with observational, theoretical, or experimental approaches. Projects should be focused on topics that meet the guidelines for research funded by the Division of Earth Sciences. -------------- next part -------------- An HTML attachment was scrubbed... URL:
