Dumpsite Seabed Characterization of the San Pedro Basin, CA, From Autonomous Vehicle Observations

Journal of Field Robotics, EarlyView.
ABSTRACT A wide‐area seabed survey was conducted using autonomous underwater vehicles (AUVs) in a known dumpsite off the coast of Southern California that has been found to have widespread sediment contamination from the chemical dichlorodiphenyltrichloroethane (DDT).

AURP: An AUV-Aided Underwater Routing Protocol for Underwater Acoustic Sensor Networks

Sensors, 2012
Deploying a multi-hop underwater acoustic sensor network (UASN) in a large area brings about new challenges in reliable data transmissions and survivability of network due to the limited underwater communication range/bandwidth and the limited energy of ...

Hybrid Path Planning Using a Bionic-Inspired Optimization Algorithm for Autonomous Underwater Vehicles

Journal of Marine Science and Engineering, 2023
This research presents a hybrid approach for path planning of autonomous underwater vehicles (AUVs). During path planning, static obstacles affect the desired path and path distance which result in collision penalties.

Deep learning‐based super‐resolution reconstruction and improved YOLOv9 for efficient benthos detection: a case study at Lake Hamana, Japan

Remote Sensing in Ecology and Conservation, EarlyView.
This study presents a UAV‐based framework that integrates deep learning‐based super‐resolution reconstruction and an enhanced YOLO detector to improve centimetre‐scale benthic organism monitoring. Using hermit crabs in Lake Hamana, a coastal lagoon in Japan, as a case study, the method substantially enhanced small‐object detection performance ...

Scalable low‐cost seabed landers: the missing link for sustained, integrated, long‐term observations in dynamic shallow seas

Remote Sensing in Ecology and Conservation, EarlyView.
Seabed landers, when equipped with a range of biotic and abiotic sensors, offer a non‐invasive and cost‐effective solution for ecosystem‐scale monitoring of Essential Biodiversity Variables (EBVs) and Essential Ocean Variables (EOVs) in dynamic shallow seas.

Marine DC resistivity and self-potential survey in the hydrothermal deposit areas using multiple AUVs and ASV

Terrestrial, Atmospheric and Oceanic Sciences, 2020
Detecting resistivity and self-potential (SP) anomalies is useful for the exploration of hydrothermal deposits. Using autonomous underwater vehicles (AUVs) can increase survey effectiveness because it allows stable posture control without a towing wire ...

DeepZoo: A cost‐effective and modular sampler for ecological studies in the deep ocean

Methods in Ecology and Evolution, EarlyView.
Abstract Understanding the structure and dynamics of deep‐ocean communities requires effective sampling of pelagic organisms in near‐bottom waters. These dispersive organisms contribute to biodiversity, connectivity and ecosystem recovery. Yet, current sampling methods remain constrained by size, cost, and depth, leaving key questions unanswered in ...

A measurement distribution framework for cooperative navigation using multiple AUVs [PDF]

2010 IEEE International Conference on Robotics and Automation, 2010
In recent years underwater survey and surveillance missions with more than a single Autonomous Underwater Vehicle (AUV) have become more common thanks to more reliable and cheaper platforms, as well as the addition of remote command and control communications using, for example, the WHOI acoustic modem.

Whole‐Brain Monosynaptic Inputs to and Axonal Projections From Posterior Insular Cortex GABAergic Neurons in Mice

CNS Neuroscience &Therapeutics, Volume 32, Issue 9, September 2026.
We mapped whole‐brain inputs and outputs of PIC GABAergic neurons. This study revealed that PIC GABAergic neurons receive dense inputs from the isocortex and thalamus and send strong projections to the basal ganglia and amygdala, with these regions constituting key hubs of the connectivity network.
