Localization of underwater gliders with acoustic travel-time in an observation network

, 2016
This paper presents a method to localize underwater gliders in observation networks, and this method is also applicable to other vehicles. Utilizing the travel time of acoustic signals from near-surface acoustic sources, the dead-reckoning positions of ...

Aquatic macrophytes as nature‐based solutions: Challenges and opportunities across inland and coastal waters

Limnology and Oceanography Letters, Volume 11, Issue 4, July 2026.
Abstract Macrophytes are foundation species whose use as nature‐based solution (NbS) in aquatic ecosystems can help reduce climate change impacts while mitigating biodiversity loss. The discrepancy in research and application of macrophytes as NbS across inland and marine coastal ecosystems is an opportunity to expand the concept and learn from ...

QUANTIFICATION OF THE OCEANOGRAPHIC CONTRIBUTORS TO TIME-VARIANCE IN THE UNDERWATER ACOUSTIC CHANNEL DURING THE DALCOMMS1 EXPERIMENT

, 2018
Underwater acoustic communication is a key enabler for civilian and military applications such as ocean sampling networks, offshore exploration, pollution monitoring and underwater surveillance (Akyildiz et al., 2005).

Enhancing Mechanical and Physical Properties of Jute/JUCO/Glass Fiber Hybrid Composites Through TiO2 and CuO Microparticle Reinforcement

SPE Polymers, Volume 7, Issue 3, July 2026.
Symmetrical Jute/JUCO/Glass hybrid epoxy composites were reinforced with TiO2 and CuO microparticles. Incorporating 3 wt.% CuO increased tensile strength by up to 63.7%, while 3 wt.% TiO2 maximized flexural and impact properties alongside superior moisture resistance, demonstrating that these fillers significantly enhance natural fiber biocomposites ...

Quantifying Southern Sea Otter (Enhydra lutris nereis) Reactions to a Quadcopter Drone in Central California

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Drones are useful for wildlife research and management, but they can cause disturbance and harassment to wildlife. Sea otters (Enhydra lutris) are candidates for drone‐based observation and monitoring but are vulnerable to disturbance. No studies have evaluated drone effects on sea otter behavior, but based on prior disturbance studies, we ...

Advancing Marine Bioacoustics With Deep Generative Models: A Hybrid Augmentation Strategy for Southern Resident Killer Whale Detection

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Automated detection and classification of marine mammal vocalizations is critical for conservation and management efforts but is hindered by limited annotated datasets and the acoustic complexity of real‐world marine environments. Data augmentation has proven to be an effective strategy to address this limitation by increasing dataset ...

Killer Whales in the Central Tropical Pacific: Occurrence, Resightings, Morphology, and Acoustics

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Compared to their well‐studied coastal temperate counterparts, killer whales (Orcinus orca) in tropical‐subtropical and oceanic areas are under‐documented. We used sighting, photo‐identification, and acoustic data of killer whales in the central tropical Pacific (CTP), collected from multiple platforms between 2002 and 2023, to assess their ...

Adaptive Acoustic Monitoring for Endangered Cook Inlet Beluga Whales in Complex Soundscapes

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Effective conservation of the endangered Cook Inlet beluga whale (Delphinapterus leucas) requires comprehensive spatiotemporal data, yet monitoring efforts remain spatially biased, underrepresenting important southern habitats. Passive acoustic monitoring (PAM) provides the necessary broad‐scale coverage, but its expansion introduces ...
