GSRS at Virginia Tech

The Geosciences Student Research Symposium (GSRS) is a 23-year tradition at Virginia Tech that brings students and faculty from across the department together for two-day program of oral and poster presentations covering the broad range of research done in our department. This student-led, two-day event is very popular among the student body and an excellent way to make your research and research interests known. If you are interested in donating to the GSRS Crowdfund please follow the link below.

Seismic interpretation effectiveness

Here’s a really cool paper by Claire Bond and others on different styles of (and overall) interpretation of modeled data. The project assesses how nearly 200 experts, both academic and from industry, interpret the same structurally complex seismic section. Numerous interpretations came out of the study and the group concludes that advanced academics are more likely to effectively interpret the data. I think a bigger takeaway is; a fundamental geoscience background is critical in geophysical work! This was an exercise in our seismic strat class a few weeks ago and a really nice project to share with students at all levels.

ExxonMobil Bighorn Basin field course

I had the opportunity this past week to join ExxonMobil and a select group of students from across the U.S. in a field course throughout the Bighorn Basin of northwest Wyoming. The trip was a great way to connect with ExxonMobil employees and students alike outside of the classroom in a unique geologic setting. The course included field-based, team-orientated analyses of hydrocarbon play elements and highlighted the sensitivity and complexity of an oil/gas system. Many thanks to ExxonMobil for a great experience!

Summer 2017 update

Rachel and I have finally finished the move to Blacksburg and I’ve started my day-to-day at VT. It’s been a relatively smooth transition but we’re still getting used to hills…

A bulk of my summer is devoted towards sample prep of sediment from IODP Exp. 342, Site U1406 (offshore Newfoundland; for grain-size analysis. At VT, we measure the mean of the terrigenous fine fraction (<63 microns) and analyze the sortable silt proxy (10-63 microns). This range is thought to be a useful indicator of water velocity, as smaller grains/particles (i.e. clay minerals) tend to act cohesively and create aggregates which behave as larger grains and deposit accordingly. Lab work this summer includes decarbonation, sieving, and running samples through our x-ray Sedigraph.

I will also be incorporating seismic reflection data to my dissertation, with the major goal of further interpreting the broad depositional patterns of the North American Atlantic margin. I hope to identify a number of lines along the margin to help with this. As you can see, we aren't really hurt for data…

seismic coverage

Lastly, I am working to polish up a few manuscripts for submission. Updates to follow.
