JOHNS HOPKINS UNIVERSITY

During my time at Johns Hopkins University, I served as a Research Assistant for a joint project between the Johns Hopkins Departments of Mechanical Engineering and Earth and Planetary Sciences. This project was funded by the National Science Foundation (NSF) to study near boundary layer flow of ocean currents. These currents are responsible for the transport of a large portion of ocean plant life and pollutants. The study leveraged a custom article image velocimetry (PIV) system used laser light to illuminate 2D planes of the water column and track individual particle movement from frame to frame in high speed photos. This is the published research article from the study.
In the months prior to deployment, my responsibilities included the assembly and test of the submersible systems. Additionally I helped to integrate multiple sensors including, cameras, lenses, and acoustic doppler velocimeter. Using CAD, I modeled the PIV system to calculate its mass and center of gravity for stable deployment. I also wrote Matlab code for real time visualization of sensor data. My research position culminated in a two week trip on a research vessel, miles off the coast of Delaware. During the expedition the PIV system was deployed multiple times and numerous data sets were recorded.

Aboard a 150’ research vessel, the PIV system awaits deployment. Measurements are taken at night so maximum contrast between the illuminated particles and water can be observed.

A small portion of the data collected and published in the Journal of Atmospheric and Oceanic Technology. Shown is a vector map of the of the near-boundary layer flow of an ocean current.

All hands on deck as the PIV system is deployed into the Atlantic miles off the coast of Delaware.
