HPC is increasingly being used in solid Earth Geophysics in Europe and AuScope has organised this Special Seminar with Arnau Folch, leader of the EU ChEESE Program

ChEESE is the EU Centre of Excellence for Exascale in Solid Earth and develops translational research capabilities in High Performance Computing to the Exascale in geophysics, enabling multiscale, multiphysics and multi-hazard analysis.

In this seminar, Arnau will present the results of ChEESE-1P Exascale Pilot Demonstrators, including:

·  Rapid probabilistic forecasts of tsunami inundations; 

·  Earthquake source prediction; and

·  The atmospheric volcanic ash dispersal models validated in real time against high-resolution geostationary satellite data.

And, introduce ChEESE-2P and highlight its role in an ecosystem of projects that are shaping Europe’s Digital Future, including:

·  A Digital Twin for GEOphysical Extremes (DT-GEO);

·  Destination Earth (DestinE); and 

·  European Plate Observing System (EPOS)

Date: February 6th from 12 pm to 1:30 pm AEST.

Please register here via Eventbrite.

Background

The first phase (ChEESE-1P) ran from 2018-2022 and addressed scientific and technical computational challenges in moving existing systems to Exascale in seismology, tsunami science, volcanology, and magnetohydrodynamics. ChEESE-1P initiated the optimisation of 10 Community flagship European codes for the European pre-Exascale and Exascale supercomputers and developed 12 Pilot Demonstrators (PD) that enabled services oriented to critical aspects of geohazards, including hazard assessment, urgent computing, and early warning forecasting.

Following the success of ChEESE-1P, a second 4-year phase (ChEESE-2P) with funding of € 7.8 million was launched in January 2023. Arnau will lead a team of Earth and Computer Scientists across multiple programs that will further develop the ChEESE-1P codes and new codes in geodynamics and glaciology.

We are delighted to be hosting Arnau and welcome you to join us in what will surely be a great seminar.

Title: Challenging land seismic surveys, from design to implementation to imaging

Presenter: Ken Witherly

Location: Thomas Cooper Room, Coopers Alehouse, 316 Pulteney St, Adelaide

Date: Wednesday 23rd November

Time: 5:30 pm for a 6:15 pm start

Cost: Members & students free, non-members $10, includes finger food & drinks

It is my pleasure to invite you to our upcoming technical event, on Wednesday 23th November at 5:30 pm for a 6:15 pm start at the Thomas Cooper Room, Coopers Alehouse.

We have Ken Witherly from Condor Consulting speaking on ‘Electrical characteristics of porphyry copper deposits’

Overview:

Electrical methods have been applied to the search for porphyry copper and IOCG deposits since the early 1950s.  While there is a generally accepted model of disseminated sulfides giving rise to a chargeability response, no clear association has been attached to what EM surveys may be responding to. Work in the early 1990s (Nickson 1993) showed the well-developed supergene blankets over a porphyry copper could be conductive; this observation was
however, never applied formally to generally accepted porphyry targeting models. The presence of other conductive zones associated with porphyry copper deposits is even less well studied. On the geological side, while there is a vast body of literature describing porphyry copper deposits and how to discover them, in very few cases do these studies even speculate if anomalous concentrations of sulfides could be conductive. On the geophysical side, observations of unexpected conductivity associated with porphyry systems is sometimes noted but these observations typically stop short of suggesting that there could be a more general observation made that a new class of geophysical feature should be defined. The present study is felt to have gathered a sufficient number of case studies which show that a significant number of porphyry copper deposits posse a mineralogical character which can be identified with EM techniques. This thesis can have significant implications as to how porphyry copper are explored for, especially those at depths >500 m, a generally accepted cut-off for IP techniques.

Abstract:

Doing geology on other planets, such as Mars, requires for the time being the use of remote controlled rovers. The Curiosity rover on Mars is a rather sophisticated (and expensive) piece of machinery, but geological investigations by rover are labor intensive and slow when compared how we would do comparable tasks on Earth. Although the rover allows us to “see” and “analyze”, critical facets of a geologists traditional “sensory repertoire” are not available (poking around, feel, sound, breaking stuff, smelling and licking). To make up for these deficiencies a large group of highly trained professionals do their level best to analyze the available data and try to arrive at sensible interpretations of what we see. Science by committee, however, has unique risks and “consensus” assessments can still be off-target. Thus, to have more than one well-reasoned interpretation for a single site is not uncommon. Nonetheless, the limitations of this brand of geologic exploration do not hinder progress, and at times they can give us unthought-of new perspectives on things that have become so routine on Earth that we take them for granted (even though we should not). How a limited set of observations can be used to deduce basic modes of sedimentation, diagenesis, and stratal organization in Martian mudstone successions serves as an example on how one could for example do “petrography” without the benefit of a thin section and still make substantial progress. In rover geology you either push your limits or you suffocate in your comfort zone. There is no try.
