The Annual Student Pizza Night will be held on Friday March 15th, jointly with the Adelaide University Geological Society. Each year we hold this event at the University of Adelaide with the aim to promote the opportunities and benefits of studying geophysics to undergraduate students. We will have industry professionals giving talks on their careers along with pizza and drinks with a chance for industry professionals and students to network. We hope as many members as possible can make it to chat with the students and share their own experiences.

This year we will be joined by Dr Stephan Thiel from the Geological Survey of South Australia, and Bonnie Lodwick, from Santos. This represents a fantastic chance for students to hear about the breadth of opportunities that our industry can offer them and a great opportunity to network with industry and government geophysicists. The ASEG SA/NT Branch is very thankful for Stephan and Bonnie for agreeing to join us.

Please note that due to the Fringe the Mawson Building will be locked. Some members of ASEG will remain around the main entrance to let participants in. After the pizza and talks there will be ample opportunity for networking. Then there is the opportunity to continue networking a little more informally, and watch some live music at the RCC Fringe area (free entry before 9 pm) just outside the Mawson Building. After dark, 'Dusk till Dawn' transforms the grounds of RCC Fringe into a playground of music, art and light, with over 120 artists and musicians performing over five weekends.

Compressive Seismic Imaging (CSI): Keith Millis, SAExploration

The Shannon-Nyquist Sampling Theorem has long governed seismic theory and formed the basis for proper seismic design. It states that a continuous function can be completely described by a series of discrete samples, provided the sample rate is at least two times the maximum frequency present within the signal. Compressive Sensing (CS) – a technique used in medical imaging and digital cameras – has shown that perfect reconstruction is still possible when the sample-rate criteria is not satisfied.

Compressive Seismic Imaging (CSI) is the application of CS theory to seismic. Through proper spatial sampling, known as Non-Uniform Optimal Sampling (NUOS), CSI has shown distinct advantages to seismic imaging, including drastic increases in fold, trace density and bandwidth; proper noise attenuation of previously challenging surface wave modes; improved imaging both generally and in areas with substantial infrastructure; footprint attenuation; among others. As the evolution of seismic imaging continues, we will highlight the impact of CSI, blended acquisition, and broad bandwidth, with examples from various case studies.

Cost

$10 for non members, free for students and members.

Cocktail food and drinks provided.

Throughout his career at Anderson Exploration, Devon Canada, BJV, with leadership roles at OptiSeis and SAExploration, he has pursued imaging improvements through innovative acquisition design, modeling, processing, and IFQC on seismic programs around the world. He has presented several times at GeoConvention, SEG Annual Meetings, and published papers in the CSEG Recorder. In addition to industry and volunteer positions, he is an avid musician who enjoys raising his two daughters and son.
 

It is with great pleasure I write to invite you to our first technical event for the year- with the ASEG President Marina Costelloe from Geoscience Australia as our guest speaker, and a short AGM. 

The event will be held at the beautiful historic Ayers House, in the Ballroom. We will have a brief AGM followed by a presentation by Marina, “The Australian Society of Exploration Geophysicists: The President, Diversity and Science.” A cocktail lunch and drinks will be served with a small cost of $5 for members and students, and $15 for non-members. Please see more details in the attached PDF. Tickets need to be purchased on Eventbrite by Sunday 3rd February for catering purposes. Please contact me at sa-ntpresident@aseg.org.au with any dietary requirements or questions. 

This event coincides with International Women and Girls in Science Day, as such I take this opportunity to suggest you invite any women (or men) geoscientists who may like to come along to this event. 

Lastly, a friendly reminder to renew your ASEG membership if you haven’t yet. 

I look forward to seeing you on February 11th!

Kate Robertson 

ASEG SA/NT President

The final GeoFamily picnic for 2018 will be at the newly renovated Pityarilla Activity Hub (formerly Marshmallow Park) with a Christmas theme! All are welcome, families, friends and guests (no need to be a member, all are welcome!) Don't have kids? Come and enjoy the park and the social networking anyway. GeoFamily picnics are held to promote a healthy work/life balance, professional networking activities, and allow everyone a chance to be involved in our professional organisations. Its also a great way to foster a love of outdoors, adventure and nature play with the next generation of geoscience, engineering and metallurgy students...!

We will have some Christmas colouring, and other activities (games) and it would be great to see some Christmas cheer in action. There is a lot of shade, but remember to bring a hat and sunscreen also. There is space to scoot/ride too, and remember to pack a change of clothes as water play is a major feature of this park!

There is ample roadside parking, and some of the new facility features include:

• Marshmallow Park is fully fenced
• The rock hill with interactive water play features
• BBQs and sheltered picnic tables
• Lots of grassy spaces perfect for kicking a footy or having a picnic
• Right next to the two fenced dog exercise areas
• Brand new Exeloo toilets complete with toilet music

The national UNCOVER strategy identified the collection of a national network of magnetotelluric (MT) data as one of the highest priorities for the Australian geoscientific community. AusLAMP is a collaborative national MT project focused on acquiring long-period MT data at approximately 2,800 sites across Australia at about 50 km spacing.

The aim of this workshop is to celebrate the success of AusLAMP by bringing the MT community of Australia together with all interested in understanding the lithospheric architecture of the continent, to discuss the methodology, interpretation and future progress of this important geophysical method and associated datasets.

The workshop will also celebrate the completion of the South Australian portion of AusLAMP and the release of this new MT data. Magnetotellurics has the capacity to provide an unprecedented insight into the architecture of the Australian continent and its mineral systems. This insight is revolutionising the way in which mineral exploration is conducted and this workshop will explore the key outcomes of AusLAMP.

The 1.67 million line kilometre GCAS is the largest airborne magnetic–radiometric – digital elevation model survey in South Australia’s history, providing magnetic and radiometric data at a scale and level of detail never before seen in regional geophysical data acquisition by the South Australian government. The GCAS project team has collaborated closely with Geoscience Australia, GCAS contractors and experts in the fields of magnetics and radiometrics to ensure that current best practices are followed for the duration of the acquisition and that the range of GCAS deliverables have the potential to reinvigorate mineral exploration in the Gawler Craton.

The aim of this workshop is to demonstrate the utility of the new GCAS datasets and value-added products by bringing the principal project participants together with industry and other agencies who have an interest in the project and products to discuss methodologies, interpret the results and deliver the roadmap for the remainder of the GCAS acquisition and data releases. The complete package of project management, quality control framework and enhanced deliverables have value to other jurisdictions as it sets new standards in magnetic–radiometric–elevation data capture and delivery.
