PI: Tracy Mandel

The Ocean Hydrodynamics Lab studies turbulent flow at ocean margins. This includes topics from coastal flow through seagrass meadows and salt marshes to the surfacing dynamics of meltwater plumes discharged from marine-terminating glaciers. Our research is primarily experimental and observational, making use of the lab facilities in the Chase Ocean Engineering Lab at UNH and beautiful field sites in the New Hampshire Seacoast.

Tracy Mandel is an experimentalist in the field of environmental fluid mechanics. She received her Ph.D. in 2018 and M.S. in 2013, both from Stanford University, and her B.S. from Cornell University in 2012. Prior to joining UNH as an Assistant Professor in Mechanical and Ocean Engineering, she was a postdoctoral scholar at the University of California, Merced.

In her free time, she enjoys climbing, knitting, and coming up with fluid-vegetable puns.

You can find her on Google Scholar, ResearchGate, and occasionally Twitter.

Ocean Hydrodynamics Lab members

Dr. Theresa Oehmke - Postdoctoral Scholar in Mechanical Engineering

Dr. Oehmke is a postdoc in Mechanical Engineering at UNH, working with Prof. Chris White and with Prof. Mandel. She is a co-PI on a recently funded NH Sea Grant project focusing on the transport and dispersal of eelgrass seeds and pollen in turbulent flow through eelgrass meadows. She received her PhD from UC Berkeley and BS from MIT, all in Environmental Engineering.

Vivek Bheeroo - PhD student in Ocean Engineering

Vivek is a second-year PhD student in Ocean Engineering at UNH, working on laboratory measurements of the surface expression of submerged vegetation. This research is supported by the Office of Naval Research. Vivek received his M.S. degree in Coastal & Ocean Engineering from Oregon State University in 2019.

Zeeshan Saeed - PhD student in Mechanical Engineering

Zeeshan is a second-year PhD student in Mechanical Engineering at UNH, working on the dynamics and surface expression of turbulent buoyant plumes. He received his M.S. degree in Mechanical Engineering from Oklahoma State University in 2019.

Lab alumni

Jenna Ehnot - Undergraduate Researcher

Jenna graduated with a B.S. in Ocean Engineering from UNH in May 2022. Her research focused on seasonal variation in the biomechanical properties of dune plants, with the goal of understanding how plant stiffness and breakage throughout the year might affect the hydraulic properties of marshes. Check out Jenna's poster from the 2022 Undergraduate Research Conference here! This research was supported by New Hampshire Sea Grant.

Matthias Page - Undergraduate Researcher/Engineer

Matthias graduated with a B.S. in Ocean Engineering at UNH from May 2022. During his time in the lab, he designed, built, and programmed a small-scale wave tank and was the lead designer of the lab's new 10m recirculating flume.

Aidan Thayer - Undergraduate Researcher/Designer

Aidan graduated with a B.S. in Ocean Engineering from UNH in May 2022. He worked on the design and construction of the lab's new 10m recirculating flume.

Matthew Dowling - MEng student in Ocean Engineering

Matt graduated with an MEng in Ocean Engineering in May 2022. For his MEng project, he conducted experiments on the effectiveness of bubble screens in controlling the escape of turbidity/density currents from dredging areas.

Jobel Villafañe-Pagán - Undergraduate Researcher

Jobel was a visiting researcher at UNH in Summer 2021, hosted by the Coastal Research Response Center and the School of Marine Science and Ocean Engineering. He studied the settling of oceanic particles such as sediment, plastic, and marine snow in ambient density stratification.

Jobel is currently a senior in Geology at the University of Puerto Rico - Mayagüez.

Senior Project Teams

  • Ocean Engineering Senior Project Team, 2021-2022: Design and Construction of a Recirculating Flume for Lumpfish Adhesion Strength Testing (co-advised with Elizabeth Fairchild)

    • The team designed and built a modular racetrack flume for future studies to test the suction disc adhesion strength of lumpfish, a type of cleanerfish.

    • Won 1st place in Ocean Engineering projects at UNH's Undergraduate Research Conference! Check out their poster here.

  • Ocean Engineering Senior Project Team, 2020-2021: Turbidity Control with Bubble Curtains

    • The team designed and conducted laboratory experiments to study the effectiveness of bubble screens in controlling gravity currents for dredging operations. Check out their final project team presentation as part of UNH's Undergraduate Research Conference!
