Biography

Arthur Trembanis' research focuses on understanding how waves and currents shape the beach and seabed. He utilizes underwater robots to explore the sea and examine what lies on the ocean floor. Exploration sites include shipwrecks, artificial reefs, and mesophotic corals.

Trembanis develops new autonomous underwater robot technologies and data visualization techniques. Expeditions include sites throughout the Caribbean (Bonaire, Cayman Islands, Bermuda, Saba), throughout the Mediterranean and Agean seas, the Black Sea, Delaware Bay, New Zealand, Bikini Atoll amongst many others.

Much of Trembanis's recent work involves developing and utilizing machine learning (artificial intelligence) to understand coastal dynamics and imagery analysis. A major focus is on helping the build and expand the Blue Tech portion of the larger Blue Economy which involves partnering with commercial, educational, and agency stakeholders in building autonomous robots and the workforce to operate them in challenging marine environments.

Hydrodynamics and Sediment-Transport Pathways along a Mixed-Energy Spit-Inlet System: A Modeling Study at Chincoteague Inlet (Virginia, USA)

Journal of Marine Science and Engineering

2023 Tidal-inlet systems are dynamic features that respond to short-term (e.g., storms) and longer-term processes (e.g., sea-level rise, changes in tidal prism). The Chincoteague Inlet system, located along the northern Eastern Shore of Virginia (USA), is a dynamic coastal complex that experiences rapid change associated with sediment redistribution and a shifting inlet throat due to the southern elongation of adjacent Assateague Island.

Deep learning for pockmark detection: Implications for quantitative seafloor characterization

Geomorphology

2023 Occurring globally, pockmarks are seafloor depressions associated with seabed fluid escape. Pockmark ubiquity and morphologic heterogeneity result in an irregular seafloor that can be difficult to quantitatively describe. To address this challenge, we test the hypothesis that deep-learning based object detection and segmentation can be used to develop data-driven models for pockmark identification and characterization.

Development and Field Testing of an Optimal Path Following ASV Controller for Marine Surveys

IEEE

2022 Marine autonomous vehicles deployed to conduct marine geophysical surveys are becoming an increasingly used asset in the commercial, academic, and defense industries. However, the ability to collect high-quality data from applicable sensors is directly related to the robustness of vehicle motion caused by environmental disturbances.

Mechanisms and Rates of Sand Bypassing along a Rapidly Evolving Inlet-Spit System

AGU Fall Meeting 2021

2021 Chincoteague Inlet and the proximal barrier islands of Chincoteague, Assateague, and Wallops comprise a dynamic coastal complex that is experiencing rapid change associated with sediment redistribution (erosion and deposition) and a shifting tidal inlet and flood- and ebb-tidal delta sands. Understanding the morphodynamic and sediment-transport processes and underlying hydrodynamic and geomorphic controls within this rapidly evolving inlet spit system is critical to developing a regional sediment management plan that is protective of the Town of Chincoteague, southern Assateague Island, and the Mid-Atlantic Regional Spaceport and the NASA flight Facility on Wallops Island.

Developing a CNN for automated detection of Carolina bays from publicly available LiDAR data

Authorea Preprints

2020 For over a century, the enigmatic Carolina bays have captivated geologists and spurred contentious debate on their origin. These circular to ovate and shallow (median diameter of 222 m, median depth of 2.17 m, median area of 26,249 sq. m) depressions span the Atlantic Coastal Plain (ACP) from northern Florida to southern New Jersey, with total counts ranging between 10,000 and 500,000. Using 1 meter gridded, 1.7 km by 1.7 km LiDAR digital elevation models (DEMs) of Delaware as training images, a convolutional neural network (CNN) was trained to detect Carolina bays.
