A postdoctoral research position is available for a three-year National Science Foundation-funded project titled “Collaborative Research: Internal tide decay mechanisms and their effects on the heat budget in the equatorial Pacific.” The successful candidate will provide crucial numerical modeling support for the NSF-funded MOTIVE (Mixing belOw Tropical Instability waVEs) project, a large national collaboration of observational scientists. This role involves close collaboration with co-PI Dr. Barkan at the University of California in Los Angeles. The MOTIVE project will deploy long-term moorings and conduct in-situ surveys focused on tropical instability waves, internal waves, their interactions, and the resultant mixing processes within the equatorial Pacific. The primary objectives of the postdoctoral researcher and the associated team are to perform and diagnose model simulations to enhance the understanding of internal tide decay as they propagate across the equatorial Pacific.

Primary Job Duties and Responsibilities

• Develop and implement numerical ROMS simulations focused on the equatorial Pacific.
• Generate and deliver model data to MOTIVE scientists to inform observational cruise planning and mooring deployments.
• Validate the accuracy of ROMS simulations through rigorous comparison with datasets from TPXO, SWOT, and mooring observations.
• Employ advanced coarse-graining and modal decomposition techniques to analyze simulations, quantifying cross-scale fluxes and ocean mixing processes.
• Actively collaborate with project scientists and students to foster a productive research environment.
• Participate in project meetings, including travel, to discuss progress and facilitate knowledge exchange.
• Lead the writing of approximately one first-author manuscript per year for peer-reviewed publication related to the NSF project and contribute as a co-author on other relevant manuscripts.
• Present scientific findings at national and international conferences to disseminate research outcomes.
• Contribute to the preparation of annual reports for the funding agency, as needed, and undertake other responsibilities as assigned.

MINIMUM QUALIFICATIONS

Applicants must have a Ph.D. from an accredited college or university in physical oceanography or a similar field or must have successfully defended no later than December 31, 2024. Applicants must also have a publication record that illustrates the ability to conduct and communicate independent research and experience with diagnosing ROMS simulations and observational data, running ocean models, coding, time series analysis, and internal wave processes. The successful candidate will be required to pass a USM employment background check and a NASA background security check to work at Stennis.
