Olamide Dada, Ms Student University of Louisiana. Geology intern Black Elk Energy Thinking outside the box: (GEO)Physics as a career option
4
Question 1: What geophysics careers do you know about? Let’s get started Question 2: What geophysics subjects are you interested in? What geophysics skills do you already possess? Question 3: What are your other interests? What other skills do you possess?
5
Geophysicists Measure, examine, model, and explore the physical properties of Earth and other planetary objects, from the depths of the ocean to the tops of volcanoes, from Earth’s core to the edges of space and beyond.
6
Geophysics specialties Seismologist - study of earthquakes and the propagation of elastic waves through Earth or through other planet-like bodies. Marine geophysicist Petroleum geophysicist Mining geophysicist Environmental geophysicist Exploration geophysicist Data used…. Active seismic Electrical resistivity Electromagnetics GPS Gravity Infrasound Magnetics Passive seismic Data used…. Active seismic Electrical resistivity Electromagnetics GPS Gravity Infrasound Magnetics Passive seismic
7
How I came to geophysics… I took a geophysics course at the University of Oklahoma Worked with the USGS in finding faults responsible for earthquakes We use geophysical methods in exploration of oil and gas. PAST FUTURE Where will you drill?
8
Well-positioned for a GEOphysics career...

University Of Oklahoma Olamide Dada Preliminary Analysis of a High Resolution Seismic Profile Acquired Near Marianna, Arkansas
13
Objective Image the upper 1 km that underlies a set of Holocene sandblows Determine whether an earthquake fault underlies the lineament of sandblows

Data Quality
17
Paleozoic (Pz) Cretaceous (K) Tertiary (T) Quaternary ?(Q) ? Depth section Profile 1 – Hwy 243 Mar1 stk4 rstatK, unmigrated, post-stack filtering (FX decon, eigenvector filter), depth converted using vel3 single, 7-26-2010 Lineament xing East 1 km
18
Well known marker reflections imaging the top on the Paleozoic and overlying Cretaceous section There is a 20m fold on Eocene reflections at 400m depth There is a discontinuity in the Paleozoic reflections at 1100m depth, that is suggestive of steeply dipping reverse faulting. More processing and analysis is required to clarify this interpretation. Conclusion
19
Limitations of our study Vertical fault displacements could be smaller than the minimum resolution of the data Faulting lies outside the image area

Exploring (GEO)physics further Attend Geoscience colloquium – ADD DETAILS FOR TALKS ON CAMPUS OR NEARBY Take an elective from the Geoscience Dept. E.g. ADD GEO COURSE or TWO OFFERED ON CAMPUS Participate in a summer internship experience! IRIS Undergraduate Internships in Seismology UNAVCO’s Research Experiences in Solid Earth Sciences (RESESS)
21
IRIS 9 to 14 week summer internship Participants distributed both within the US and abroad – virtual communication emphasized. Research projects include all specialties within seismology Travel and weekly stipend ($550/week) Full funding to present research at the Fall AGU conference in San Francisco, CA Diversity Focused 10 week summer internship All participants located in Boulder, CO Research projects include a variety of solid Earth science topics Travel, lodging and weekly stipend ($550/week) Support in fall: $, GRE, scholarships & grad. school applications Internship Opportunities Deadline for both programs is February 1, 2014
