Sustainable Development Goals Applied to the Maritime Transportation Sector: Setting Sail for the Future

open access: yesNatural Resources Forum, EarlyView.
ABSTRACT The 2030 Agenda for Sustainable Development aims to eradicate poverty, protect the environment, and promote prosperity through 17 Sustainable Development Goals (SDGs). Achieving these goals requires a multi‐sectoral approach. Maritime transportation, vital to the global economy, significantly contributes to several SDGs and plays a strategic ...

A scheme to analyze the influence of ocean sound propagation on passive sonar target classification and recognition

open access: yesAIP Advances
The time-varying, space-varying, and frequency-varying characteristics of the marine environment severely affect the classification and recognition of underwater passive sonar targets.

Sailing Through Time: Building Pacific Maritime Resilience

open access: yesGlobal Policy, EarlyView.
ABSTRACT This article examines the Pacific Blue Shipping Partnership (PBSP), an ambitious initiative aimed at decarbonising maritime transport across Oceania. The study explores the cultural, historical and technological aspects of wind‐propelled shipping in the Pacific.

The Classroom as a Work of Art

open access: yesInternational Journal of Art &Design Education, EarlyView.
Abstract This article is the product of a project that stems from an educational environment, challenges it, and aims to transcend its boundaries. Within the project, the ordinary flow of a classroom was intervened with through play, and ways to reunite students – who are often perceived as ‘surpluses’ within the current education system – were ...

Impact of light pollution on fishes: Mechanisms and ecological consequences

open access: yesJournal of Fish Biology, EarlyView.
Abstract The increasing prevalence of artificial light at night (ALAN) is of growing ecological concern. By altering natural light regimes, ALAN affects the behaviour, physiology and life‐history of organisms. While research has largely focused on terrestrial ecosystems, aquatic ecosystems are increasingly exposed.

Model for the radiated noise source spectra of merchant ships [PDF]

open access: yesThe Journal of the Acoustical Society of America, 1976
Ocean ambient noise in the frequency range 20–300 Hz is, in many cases, dominated by the radiated noise from merchant ships [G. M. Wenz, J. Acoust. Soc. Am. 34, 1936 (1962)]. Predictions of noise in this frequency regime have usually been based on a ship spectrum of a highly simplified type.

A Year in the Bones: Investigating Bone Resorption Across a Reproductive Year in Wild Female Assamese Macaques

open access: yesJournal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Reproduction places considerable metabolic demands on females, particularly during pregnancy and lactation, when calcium homeostasis and bone metabolism are challenged. Urinary C‐terminal telopeptide of type I collagen (CTX‐I) offers a useful non‐invasive marker to assess bone resorption.

Using Small Unoccupied Aerial System (sUAS) Multispectral Imagery to Compare Hydrodynamics Around Different Aged Patches of Marsh Vegetation

open access: yesEcohydrology, Volume 19, Issue 7, November/December 2026.
ABSTRACT Wetland vegetation influences water and sediment transport by altering flow resistance. Vegetation presence, stem density, leaf and stem morphology, and flexibility, among other characteristics, control the degree to which vegetation impacts transport patterns.

Radiated Noise Measurement of Ships Based on Stochastic Resonance [PDF]

open access: yesThe Open Mechanical Engineering Journal, 2015
The radiated noise of ships involves strong low-frequency line spectrum, which is greatly related with the working states of auxiliary equipment and the rotation of propeller, and then regarded as the important basis in feature extraction of ships. Moreover, the stochastic resonance has special advantages in the extraction of weak signal. Aiming at the
