ABSTRACT The FAO's “blue transformation” roadmap necessitates a fundamental shift towards precision aquaculture to meet global food security targets while minimizing environmental footprints. This review provides a comprehensive overview of how artificial intelligence (AI) and decision support systems (DSS) serve as pivotal enablers for the “better ...

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

Abstract It has recently been demonstrated that modern recreational fish finders with high‐frequency (800 kHz) Sidescan transducers can detect submerged human bodies. This ubiquitous technology is widely used on the water and has the potential to be utilized for the rapid detection of submerged decedents in any waterbody.

Cache‐Cache: Dans les souffles du Grand Fleuve…
ABSTRACT Between ventriloquism and divination, devotion and consecration, an old and sublime marine game unfolds each day, with living breaths shared in the waters of the great river. In Tadoussac, on the north shore of the St. Lawrence Estuary, at the mouth of the Saguenay, the rumor of whales has long resonated.

Sonar-Based Simultaneous Localization and Mapping Using the Semi-Direct Method
The SLAM problem is a common challenge faced by ROVs working underwater, with the key issue being the accurate estimation of pose. In this work, we make full use of the positional information of point clouds and the surrounding pixel data.

Topology‐based Visual Analysis of Hydrothermal Plumes
Abstract Hydrothermal plumes are turbulent structures of intense heat and mineral smoke that rise and disperse into the deep ocean. Existing models generally characterize these systems as a single axisymmetric plume originating from a point source. However, this assumption breaks down in weakly venting, spatially distributed systems, where low‐flux ...

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 ...
