Luis Pomales Velázquez

Ph.D. Candidate in Physical Oceanography

Before joining the OPERA lab in 2019 Luis worked for the Caribbean Coastal Ocean Observing System in Puerto Rico on a wide array of projects that exposed me to the beauty of working in the interdisciplinary field of Oceanography. Besides my interests in science, I’m an avid explorer of life in general, I enjoy anything related to art and nature.

Research:

Luis' work focuses on using oceanographical data and passive acoustic recordings collected by two buoyancy-driven Autonomous Underwater Vehicles (AUVs) to assess the sound speed fluctuation as measured during the 2017 Canada Basin Acoustic Glider experiment (CABAGE, of the tomographic Canada Basin Acoustic Propagation Experiment.) Alongside this, I use RAM, a range dependent parabolic equation numerical model, to make acoustic predictions in CABAGE and generate solutions that can successfully achieve reliable and accurate subsea vehicle localization. The goal of this work is to achieve one-way tomography using AUVs.

Savannah Passaretti

M.S. Candidate in Ocean Engineering

Savannah graduated UNH with a B.S. in Mechanical Engineering and a minor in Sustainable Ag. & Food Systems. Her undergraduate projects in aquaculture lead her to join a capstone project related to mariculture and ocean engineering. After graduating, she completed a two year contract as a research technician at Scripps Institution of Oceanography, in the Coastal Observing R&D Center, focusing on remote surface drifting wave buoys.

Research:

Savannah's research at the OPERA Lab will focus on implementing low powered floats into OPERAs vehicle fleet for data collection in various upcoming projects.

Education:

• B.S. Mechanical Engineering. University of New Hampshire, 2020

Abigail Smith

M.S. Candidate in Ocean Engineering

Abby did her undergraduate degree in Mechanical Engineering at Michigan Technological University. During this time, she interned at the Naval Surface Warfare Center Crane Division, working on sonar technology. This is what got her initially interested in underwater acoustics. She worked to develop her research skills during internships with the Department of Energy, and looks forward to developing them further in the Opera Lab. 

Research:

Abby's research focus is on modelling long range propagation and investigating their arrival structures.
