Fine‐Scale Structure and Kinematics of an Active Submarine Strike‐Slip Fault From Micro‐Bathymetric Mapping and Analog Modeling: The North Alfeo Fault Offshore Catania (Eastern Sicily)

Tectonics, Volume 45, Issue 5, May 2026.
Abstract Southern Italy and eastern Sicily have been the site of several destructive historical earthquakes. Here at the junction between the western edge of the Calabrian subduction zone and the Malta Escarpment several strike‐slip faults have been mapped, which may be the surface expression of the lateral slab tear fault and are candidate sources for

Ecology and Seasonal Habitat Use of Northern Bottlenose and Sowerby's Beaked Whales in the Azores

Marine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT Beaked whales are among the least known cetaceans, yet they are regularly observed in the Azores, a region recognized as a hotspot for deep‐diving species. In this study, we analyzed opportunistic sightings collected during 1492 whale‐watching trips, including 149 beaked whale encounters, of which 89 were Sowerby's (Mesoplodon bidens) and 31 ...

Environmental DNA Reveals Diverse and Depth‐Stratified Biodiversity in East Indian Ocean Submarine Canyons

Environmental DNA, Volume 8, Issue 2, March/April 2026.
Environmental DNA metabarcoding reveals diverse animal communities across Cape Range and Cloates submarine canyons off Western Australia. Two assays detected 234 species spanning 125 families across 11 phyla, highlighting canyon‐specific assemblages and demonstrating the value of eDNA for establishing biodiversity baselines in remote and poorly ...

Real‐Time Detection and Prevention of DoS Attack in Unmanned Marine Vehicles Using Machine Learning

SECURITY AND PRIVACY, Volume 9, Issue 2, March/April 2026.
ABSTRACT Unmanned marine vehicles (UMVs) are one of the most crucial components of the underwater communication and surveillance system in the marine and oceanographic environment. This research introduces a novel approach to stabilize the connection in an unstable underwater environment by inheriting features of communication velocities.

Conceptual Design of Future Undersea Unmanned Vehicle (UUV) System for Mine Disposal [PDF]

IEEE Systems Journal, 2014
A conceptual design is proposed for an effective mine countermeasure (MCM) system, which consists of three unmanned underwater vehicles (UUVs) and 10-20 small charged deliverable vehicles. New underwater optical communication systems are introduced to improve onboard mine reconnaissance and decision making with the key technologies focused on system ...

Marine Mammals in the Anthropocene: Developing a Systematic Evidence Base of Threats to Nineteen Species

Mammal Review, Volume 56, Issue 1, March 2026.
Marine mammals are vulnerable to a variety of anthropogenic threats, yet a global systematic map of the literature for 19 species found both spatial and temporal disparity in research effort between threats and between species. There are knowledge gaps for species and threats, with effort unequal across many species' ranges.

UNDERSEA: An Exemplar for Engineering Self-Adaptive Unmanned Underwater Vehicles (Artifact).

Dagstuhl Artifacts Ser., 2017
Recent advances in embedded systems and underwater communications raised the autonomy levels in unmanned underwater vehicles (UUVs) from human-driven and scripted to adaptive and self-managing. UUVs can execute longer and more challenging missions, and include functionality that enables adaptation to unexpected oceanic or vehicle changes.

Light‐Promoted Hydrazine Dehydrogenation over Ni/NH2‐MIL‐125: Unraveling Mechanisms for Efficient Hydrogen Production

Advanced Science, Volume 13, Issue 11, 23 February 2026.
Highly dispersed and electron‐rich Ni nanoparticles (≈2.7 nm) supported on NH2‐MIL‐125 significantly promote the dehydrogenation of hydrous hydrazine under visible‐light irradiation, achieving a turnover frequency of 220.2 h−1 at 323 K, which is more than twice that in the dark (108.1 h−1) and outperforms most reported non‐precious metal catalysts ...

Private Network Realignment: State Strategies Versus Market‐Driven Globalization in the Subsea Cable Network

Global Policy, Volume 17, Issue 1, Page 94-106, February 2026.
ABSTRACT Much of the subsea cable network, which carries the vast majority of global internet traffic, is developed, owned, and operated by private corporations. In an era of growing global tensions, states have come to view these cables as critical to their interests. The article addresses the disconnect between statecraft‐centric explanations and the
