Subject: PhD Position Opening in Seafloor Distributed Fiber Optic Sensing for Ocean Hydrodynamic Observations - Oregon State University

Advisor: Dr. Meagan Wengrove (meagan.wengrove<at><meagan.wengrove<at>>),

Location: School of Civil and Construction Engineering (Coastal and Ocean Engineering), Oregon State University

At Oregon State University, we are seeking a PhD candidate to quantify the potential for using Distributed Acoustic Sensing (DAS) as an ocean bottom sensor. DAS provides an opportunity to use fiber in pre-existing telecommunication and science cables laid on the sea floor to measure ocean bottom strain at the nanoscale. DAS measures strain applied to the cable at resolutions as low as 1-2 m over distances as large as 150 km making DAS the most spatially dense and long-range measurement of seafloor dynamics of any in-situ ocean sensor. To date, DAS has been used extensively in the seismic community. Our focus will be to push the technology forward to robustly measure ocean hydrodynamics. We seek to 1) quantify the capability of DAS networks to become reliable ocean sensors and 2) use DAS to investigate spatially varying bottom dynamic pressure in the region between the nearshore to inner shelf ocean. We are preforming a set of field and laboratory experiments to validate and verify DAS signal to ground truth measurements from trusted ocean instrumentation. Field experiments are performed in cooperation with the USACE Duck Field Research Facility and the Oregon State University Pacific Marine Energy Center. Field experiments will be performed in Oregon, North Carolina, and Hawaii. Lab work will be performed at the Oregon State University O.H. Hinsdale Wave Research Laboratory.

Qualifications: We seek applicants with strong programming skills that are interested in the challenges that accompany complex signal processing problems. Candidates with signal processing capabilities in adjacent fields are encouraged. Candidates already holding an M.S. are preferred, but not required.

Applications: Applicants should send a curriculum vitae, a one-page cover letter, and the contact information of three references to Meagan Wengrove (meagan.wengrove<at><meagan.wengrove<at>>). Please use the subject line "PhD Application for Ocean-DAS". Questions regarding the position and application procedure should be directed to the same email address. Review of applications begins immediately and will continue until the position is filled.
