“It's like this whole alphabet soup of autonomous systems, robotic systems that are giving us a force multiplier in doing ocean exploration and mapping. They give us the ability to spend more time in the environment.” - Art Trembanis

**ABOUT OUR GUEST**
Arthur Trembanis is the director of the Coastal Sediments, Hydrodynamics and Engineering Laboratory (CSHEL) in the College of Earth, Ocean, and Environment at the University of Delaware. The work of CSHEL involves the development and utilization of advanced oceanographic instrumentation, particularly autonomous underwater vehicles for seafloor mapping and benthic habitat characterization. He received a bachelor's degree in geology from Duke University in 1998, a Fulbright Fellowship at the University of Sydney in 1999, and a Ph.D. in marine sciences from the Virginia Institute of Marine Sciences in 2004. His research interests include coastal and estuarine morphodynamics, sediment transport, hydrodynamics, autonomous underwater, aerial and surface vehicles, seafloor mapping, and geoacoustics.
