Lake sturgeon (Acipenser fulvescens) growth and longevity estimated from adult capture–mark–recapture data

Journal of Fish Biology, EarlyView.
Abstract Effective fishery management policy depends on accurate life‐history data, particularly for harvested species. Longevity is a core life‐history trait that is directly related to annual survival and lifetime reproductive potential, but fish longevity is generally not well documented, particularly for long‐lived species.

Head and Whisker Behaviours Observed During Foraging in Northern Elephant Seals (Mirounga angustirostris)

Ecology and Evolution, Volume 16, Issue 5, May 2026.
We observed a range of behaviours during foraging, including forward swimming, vertical diving, swooping, dabbing, sweeping and rotations. Head dabbing was also sometimes accompanied by the seal producing infrasounds, the bouts of which coincided with rhythmic whisker protractions. ABSTRACT Pinnipeds use their whiskers to detect and follow hydrodynamic

PING‐Mapper: Open‐Source Software for Automated Benthic Imaging and Mapping Using Recreation‐Grade Sonar

Earth and Space Science, 2022
The characterization of benthic habitats is essential for aquatic ecosystem science and management, but is frequently limited by waterbody visibility and depth. Recreation‐grade side‐scan sonar systems are increasingly used to aid scientific inquiries in

CONCERT: A Modular Reconfigurable Robot for Construction

Journal of Field Robotics, Volume 43, Issue 3, Page 1332-1362, May 2026.
ABSTRACT This paper presents CONCERT, a fully reconfigurable modular collaborative robot (cobot) for multiple on‐site operations in a construction site. CONCERT has been designed to support human activities in construction sites by leveraging two main characteristics: high‐power density motors and modularity. In this way, the robot is able to perform a

Highly Variable Methane Production and Fluxes in a Hypereutrophic Lake Despite Uniform Bathymetry and Sediment Chemistry

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 5, May 2026.
Abstract Hypereutrophic lakes support high sedimentation of labile organic carbon, promoting sediment anoxia and GHG potential production. Lakes with complex morphometry exhibit extensive spatial heterogeneity in sediment methane (CH4) and carbon dioxide CO2 dynamics. We wondered: do lakes with uniform bathymetry show low spatial variation in sediments'

A Mapping Method Fusing Forward-Looking Sonar and Side-Scan Sonar

Journal of Marine Science and Engineering
In modern ocean exploration, forward-looking sonar (FLS) provides real-time 2D imaging of the seabed ahead, but its detection range is relatively limited.

Caratterizzazione fisiografica, geomorfologica e bionomica della Rias di Santa Teresa di Gallura: Sardegna nord-orientale = Physiographic, geomorphological and bionomic characterization of the Santa Teresa di Gallura Rias (N.E. Sardinia) [PDF]

, 2011
An underwater survey in the Rias of S. Teresa di Gallura was made to characterize the benthic environment by integrating three methods: Side Scan Sonar, ROV, SCUBA diving. The main bionomic features at different depths were described and mapped.

Evaluation of Catch Performance and Environmental Impact of Technical Gear Modifications for a More Sustainable Scallop Dredging Fishery

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
Catch and environmental performance of modified scallop dredge designs were assessed. Skid belly bags increased scallop catch by 14%–19% and reduced gear wear. N‐Virodredge reduced catch of scallop juveniles and sorting time. Gear footprint on the seabed was reduced by 50% for skid belly bags. N‐Virodredge cut fuel use by 30%, reducing carbon emissions
