Stable Isotope–Enabled Particle Drift Models Predict Where High‐Resolution Isotope Analyses Can Discriminate Among Larval Trajectories in Atlantic Mackerel

Fisheries Oceanography, EarlyView.
ABSTRACT Marine fish commonly move across distinct habitats throughout their lifetimes, particularly during larval stages, when they are particularly difficult to track. Such transitions are necessary as environmental demands and predation pressures change dramatically with increases in body size.

DS-SIAUG: A Self-Training Approach Using a Disrupted Student Model for Enhanced Side-Scan Sonar Image Augmentation

Sensors
Side-scan sonar is a principal technique for subsea target detection, where the quantity of sonar images of seabed targets significantly influences the accuracy of intelligent target recognition.

Simulating the Impacts of Deep Geothermal Development on Shallow Hydrothermal Resources in a Rocky Mountain Rift Valley

Groundwater, EarlyView.
Abstract Numerical modeling has been widely used to assess the feasibility of geothermal energy development at sites across the world, but modeling applications simulating the potential impacts on shallow hydrothermal resources and surface water are relatively scarce. In this study, we apply the MODFLOW 6 groundwater energy (GWE) code to simulate fully

Critical tipping points in dung beetle communities: Implications for conservation in the Atlantic Forest biome

Insect Conservation and Diversity, EarlyView.
Minor land‐use changes consistently lead to abrupt biodiversity shifts across all diversity dimensions, favoring generalist dung beetle species while excluding sensitive specialists. These shifts are observed at lower environmental change rates than previously considered, with significant changes apparent after just 25% habitat loss.

Multi-Scale Marine Object Detection in Side-Scan Sonar Images Based on BES-YOLO

Sensors
Aiming at the problem of low accuracy of multi-scale seafloor target detection in side-scan sonar images with high noise and complex background texture, a model for multi-scale target detection using the BES-YOLO network is proposed.

A new catfish species of Microcambeva Costa & Bockmann, 1994 (Siluriformes: Trichomycteridae) from southern Brazil, with a redescription of M. ribeirae Costa, Lima & Bizerril, 2004

Journal of Fish Biology, EarlyView.
Abstract Among the few species of Microcambeva reported as occurring in more than one hydrographic basin, M. ribeirae has been previously listed from both the Ribeira de Iguape and the Guaraqueçaba basins. However, morphological and molecular analyses revealed that the specimens from Guaraqueçaba represent a new species, which is described in this ...

An Automatic Generalization Method of a Block-Based Digital Depth Model Based on Surface Curvature Features

Journal of Marine Science and Engineering
Addressing the limitations of current multi-scale seabed terrain construction methods for a Digital Depth Model (DDM) and the low computational efficiency of automatic generalization algorithms, this paper draws on the concept of curvature simplification

Marine heatwaves shape size‐dependent thermal exposure, habitat use and marine residency in Arctic char (Salvelinus alpinus)

Journal of Fish Biology, EarlyView.
Abstract Marine heatwaves (MHWs) are increasing in high‐latitude oceans, yet behavioural responses of anadromous fishes to these potential stressors during short marine feeding seasons remain poorly understood. We combined acoustic telemetry (internal temperature and depth) with satellite‐derived sea surface temperature data to quantify Arctic char ...

An Algorithm for Sound Velocity Error Correction Using GA-SVR Considering the Distortion Characteristics of Seabed Topography Measured by Multibeam Sonar Mounted on Autonomous Underwater Vehicle

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Aiming to address the problem that autonomous underwater vehicle (AUV) with multibeam echo sounder system (MBES) for underwater topographic survey cannot autonomously obtain the sound velocity of the acoustic path to correct bathymetric data, this ...

Shape of Water: Power Dynamics for Supply Chain Resilience

Journal of Supply Chain Management, EarlyView.
ABSTRACT The world is facing climate change‐driven disruptions such as extreme weather events, which affect nature as well as firms and their supply chains. Nonetheless, little is known about how supply chain players shape their socioecological resilience, including from a power perspective.
