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.

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 ...

Fish welfare in a changing world: New developments and current challenges
Abstract The welfare of non‐human animals is central to ethical discussions on animal use, with increasing attention to fish welfare across research, aquaria, aquaculture, and fisheries. This paper reviews current theoretical approaches to animal welfare and recent advances in defining and assessing fish welfare since the seminal paper by Huntingford ...

High-Resolution Sonars: What Resolution Do We Need for Target Recognition?
Target recognition in sonar imagery has long been an active research area in the maritime domain, especially in the mine-counter measure context. Recently it has received even more attention as new sensors with increased resolution have been developed ...

Abstract Dietary analysis has contributed to our understanding of animal niches, interspecific interactions, community structure and the flow of matter and energy in food webs. We employed three methods of dietary analysis to estimate trophic niche overlap between two peacock bass species, Cichla cataractae and Cichla ocellaris, across sympatric ...

Adaptive Coverage Path Planning for Underwater Sonar Scans in Environments with Changing Currents
This article considers underwater sonar scans that utilize a sonar-equipped Autonomous Marine Ship (AMS). The AMS finds an underwater object by towing a tow fish, having active sonars for imaging the sea bottom.

Abstract Introduction Over 44% of European lakes fail to meet ecological quality standards, prompting substantial investment in lake restoration to achieve good ecological status. Unfortunately, effects are often short‐lived due to persistent internal phosphorus (P) loading and strong cyprinid‐driven bottom‐up control, which limits water quality ...

River Sand and Gravel Mining: Global Drivers, Impacts, and Pathways for Sustainable Management
Abstract River sand and gravel are mined worldwide at volumes that now rival their natural replenishment, yet quantitative knowledge of this mining activity and its consequences lags far behind many other global environmental pressures. We synthesize 411 peer‐reviewed studies published since 1974 within a new Driver‐to‐Management Pathway for ...
