Geoscientist | Gulf of Mexico
Marianne Coholich is an Earth Scientist at Chevron, based in the Greater New Orleans Region. She has a strong academic background, having earned her Master of Science in Geological Sciences from Stanford University. During her studies, she was involved in the Stanford Project on Deep-water Depositional Systems (SPODDS), where she focused on analyzing modern sand deposits and their implications for geological risks, particularly in relation to offshore wind farm construction in California.1
Her research utilized advanced techniques such as jumbo piston cores and high-resolution autonomous underwater vehicle (AUV) seafloor imaging to study the Lucia Chica deep-water channel system. This work is significant for understanding earthquake periodicity and reservoir properties in deep-water environments.12
In August 2023, Coholich announced her full-time position with Chevron, where she contributes to projects in the Gulf of Mexico business unit.3 Her LinkedIn profile indicates that she has over 500 professional connections and is actively engaged in her field.2
Highlights
This month I completed my thesis, “The last days of the Lucia Chica submarine channel system, offshore central California: A geohazard assessment for windfarm infrastructure”.
I would like to thank my advisor, Steve Graham, for prioritizing teaching and mentoring while leading the School of Earth through its transition into the Stanford Doerr School of Sustainability during a global pandemic. Also, special thanks to MBARI for collaborating with me on this project and providing an exceptional dataset. And thank you to all the individual people at Stanford and in the geosciences community who supported me during these challenging yet formative years.
I’m excited to announce that I will be starting a full-time position with Chevron as an Earth Scientist in their Gulf of Mexico business unit. Looking forward to this next chapter.
Today I gave my last presentation as an Earth Science Intern at Chevron. I am extremely grateful to have experienced a fully in-person internship in Midland, Texas this summer - complete with field work and Permian Basin facility tours.
I would like to thank my amazing mentors, Andrew Roark and Lauren Bane, for their guidance as well as my supervisor, Amy DeGeest, for her leadership and support.
It has been a rewarding summer growing my capabilities and building relationships. Leaving West Texas is bittersweet, but I now have a sizable collection of Permian rock samples to take with me!
