Summary: In order to address marine debris and promote sustainable marine industries, legislation and regulations have been implemented worldwide. The International Convention for the Prevention of Pollution from Ships (MARPOL) is one of the most important agreements, focusing on reducing ship-sourced marine pollution. MARPOL Annex V, which deals with solid waste disposal, became effective in 1988 but was only amended to include a complete ban on waste disposal in 2013. Evaluating the effectiveness of these regulations is essential for informed decision-making about ocean management.

Summary: The objective of this paper is to devise and simulate a collection system based on Internet of Things technology, which is an intelligent simulator capable of sensors' imitation, relaying data, evaluating vehicle routing algorithms and calculating performance indicators. Using a numerical experience adapted from the regional context in Morocco, the metrics show that the intelligent scenario outperforms the status quo in terms of collected quantities, transportation distances and tank storage levels. The total distance travelled has decreased by 45.25%, and the average quantity collected per round has risen by 24.22%. On average, every cubic meter stored in a port saves 16.4 km of monthly travelled distances. Additional study is needed to evaluate the impact of a national coverage extent, and further tests on investment requirements in terms of network implementation and storage resources are essential to prove long-term viability of this solution.

Summary: This article introduces a combined method of remote sensing, artificial neural networks, and game theory to develop a system for safe ship traffic management at sea. It uses serial data transmission from ARPA anti-collision radar to support the computer-assisted maneuvering decisions of navigators when encountering a large number of ships. The safe and optimal trajectory of a ship is determined using static optimization, dynamic programming with neural constraints, and positional and matrix games. The presented algorithms are then used for computer calculations in a real navigational situation in the Skagerrak-Kattegat Straits recorded on the radar screen of the r/v HORYZONT II research/training vessel.

Summary: Little information is available on the evolution of chemicals in terms of types, concentrations, and distribution over the years. This study aims to establish an emerging contaminants database in the pearl river basin by reviewing the spatial and temporal distribution of emerging contaminants with limited toxicology data. The findings show that seven groups of emerging contaminants are abundant in the region, with higher concentrations detected prior to 2011. Antibiotics, phenolic compounds, and acidic pharmaceuticals are prevalent in water, while phenolic compounds are a major concern in soil. Flame retardants and plastics are extensively studied in organisms. The fluctuation of field concentrations and frequencies over time renders the current data unsuitable for regulation purposes.

Summary: In order to prevent frequent maritime accidents, researchers investigated and studied typical cases of maritime accidents along the coast of China, and constructed a network model of China's coastal maritime traffic accidents. The overall structural characteristics of the maritime accident network were analyzed based on the characteristic parameters of complex network. Additionally, through network robustness analysis based on node betweenness and PageRank value, key factors in maritime accidents were identified and risk prevention and control measures were proposed. The research showed that the maritime traffic accident network has a short average path length, high clustering coefficient, and risk spreads quickly in the network, which can lead to accidents. By managing and controlling key risk factors, the evolution of risks can be effectively blocked and large-scale maritime accidents can be reduced.

Summary: This study aims to identify factors related to seafarers' mental health and develop a mental health management model. The environment may play a pioneering role in the job demand resource model. Job demands are negatively correlated with job resources, leading to low engagement and high burnout. Job burnout, engagement, and job safety are related to turnover intention, while job unsafety may promote turnover intention. This framework can help shipping companies and policymakers design intervention strategies to improve seafarers' mental health and enhance navigational safety.

Summary: In this paper, the authors propose a two-stage pricing game model to improve container terminal operation efficiency by focusing on inbound container storage pricing. Two types of objective functions, profit maximisation and cost minimisation, are investigated for the container terminal operators. The study considers the price-dependent container storage time and derives the pricing equilibria through theoretical analysis. Numerical studies show that the cost-minimising objective is recommended to alleviate yard congestion. Container terminal operators have an incentive to increase storage prices to tackle terminal yard congestion.
