Enhancing underwater target detection: Fusion of spatio‐temporal incompletely‐aligned AIS and sonar information via DTW and multi‐head attention mechanism

IET Radar, Sonar & Navigation
In the field of underwater target detection, the passive sonar is an important means of long‐distance target detection. The sonar detection information typically includes both surface and underwater targets, whereas it is a great challenge on effectively

Behavioural Diversity of Fishes: Concepts, Drivers and Its Role in Conservation and Management

Fish and Fisheries, EarlyView.
ABSTRACT Human activity has altered nearly all ecosystems on Earth, contributing to substantial biodiversity loss across taxonomic, genetic and functional dimensions, from the intraspecific to the ecosystem scale. Yet some components of biodiversity remain hidden or underappreciated, including behavioural diversity.

Shallow water depth (≤5 m) estimation based on single-beam echo sounder and optical satellites

Geocarto International
This study combined single-beam echo sounder data with PlanetScope multispectral data to invert shallow water depth (≤5 m) around Weizhou Island, analyzing how each band's reflectance varies with depth by establishing their quantitative relationship and ...

Examining the Impact of Derelict Pots on Blue Crab (Callinectes sapidus) Catch and Harvest Within a Recreational Fishery

Fisheries Management and Ecology, EarlyView.
ABSTRACT Derelict fishing gear can negatively affect marine ecosystems through mortality in coastal environments. This study explored the impact of derelict and active crab pots on recreational blue crab (Callinectes sapidus) catch rates and landings in a Mid‐Atlantic estuary by deploying experimental pots in four habitat strata within three sections ...

Side looking sonar image quality assessment using reference targets

, 2018
Side-looking sonar systems, including side-scan sonar and synthetic aperture sonar, are widely used for seabed characterization. They also have applications in the detection and classification of objects on the seabed.

Delphi consensus: First‐line use of biologics and small molecules in hidradenitis suppurativa

Journal of the European Academy of Dermatology and Venereology, EarlyView.
This Delphi Consensus study identified upgrade criteria for the use of biologics and small molecules as first‐line therapy in hidradenitis suppurativa (HS). European HS experts evaluated 16 clinical scenarios, voting on eligibility for therapy escalation.

Modeling potential masking of echolocating sperm whales exposed to continuous 1–2 kHz naval sonar

, 2021
Modern active sonar systems can (almost) continuously transmit and receive sound, which can lead to more masking of important sounds for marine mammals than conventional pulsed sonar systems transmitting at a much lower duty cycle.

Plant‐Based Diet and Sleep Quality in Adults: Exploring the Role of Lifestyle and Health Mediators

Nutrition Bulletin, EarlyView.
ABSTRACT This study investigated the association between plant‐based dietary indices (PDI) and sleep quality and examined the mediating roles of lifestyle and health‐related factors. A total of 5260 participants (18–65 years) were included. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI). PDI—including overall (oPDI), healthy

Target discrimination in bubbly water

, 2012
A man-made sonar that can operate in bubbly water is relevant: decades of active sonar experience built up for deep water applications are insufficient for shallow water operations required of a changed maritime security landscape.
