TL;DR: In this article, the authors explored relationships between existing seaport sustainability and the current narrative that exists related to sustainability improvements, and identified operational trends linked to sustainability claimed by seaports.

TL;DR: Zhang et al. as discussed by the authors used a comprehensive weight model including the entropy method and the best-worst method (BWM) to measure the level of marine technology innovation in China's coastal regions from 2006 to 2016.

TL;DR: Wang et al. as mentioned in this paper detected and compared the spatiotemporal changes in coastline and coastal reclamation in three developed coastal areas: the Bohai Bay-Yellow River Estuary Zone (BHB-YREZ), the Yangtze River Estation-Hangzhou Bay Zone (YRE-HZBZ), and the Pearl River Estulation Zone (PREZ) using Landsat images from 1980, 1990, 2000, 2010 and 2018.

TL;DR: A new method to evaluate the importance of ports by incorporating centrality measures of networks into the TOPSIS framework is proposed and a case study of the ports along the MSR shipping network is conducted to demonstrate the feasibility and effectiveness of the proposed method in identifying essential ports.

TL;DR: Wang et al. as discussed by the authors used Landsat data for eight periods from 1984 to 2020 to explore the spatial and temporal characteristics of the land-use landscape pattern, and performed a supervised classification using the maximum likelihood-based method to obtain the information about the land use and land cover changes in the study area, and an accuracy evaluation was carried out.

TL;DR: Wang et al. as mentioned in this paper proposed a conceptual index system using entropy weight method and coupling coordination degree model for analysis of the coupling coordination relationship among the regional economy, ecological environment and island tourism.

TL;DR: In this paper, the main COVID-19 plastic pollution threats and LAC beaches' regulations are assessed based on literature research and a review of plastic waste regulations, and the main findings suggest that unifying the ongoing fragmented and overlapped policies is key to abate plastic pollution, including plastic industry regulations and circular economies.

TL;DR: In this article, an integrated vulnerability assessment of coastal erosion is essential to produce detailed and accurate erosion vulnerability information to support mitigation strategies, which can be used by concerned authorities to protect coastal erosion and minimise its effects on properties and coastal environments.

TL;DR: In this paper, the authors studied how the ship's behavior changes under ECA policy and simulated the ship evasion trajectory under different ECA policies using AIS data, and analyzed the change of ship cost and emission reduction under different policies, and found that the distorted emission reduction is increasing first and decreasing with the ECA boundary moving far away from the coastline.

TL;DR: In this paper, the authors distinguish the marine generated organic part of beach cast as a separate management object and discuss research questions related to its management and economically viable use, based on experiences from the Baltic Sea and existing practices from countries with different management systems.

TL;DR: In this paper, the authors used a slacks-based model (SBM) and considered undesired output to estimate the marine economic efficiency of 20 countries along the Maritime Silk Road (MSR) from 2007 to 2017.

TL;DR: In this paper, the authors conducted a qualitative systematic review to estimate the potential environmental effects of deepwater, floating offshore wind energy facilities during operation, as well as potential mitigation measures to address some of the effects.

TL;DR: Based on panel data of 11 coastal provinces and cities in China during 2006-2015, stochastic frontier analysis (SFA) is used to calculate the efficiency of marine science and technology innovation in this paper.

TL;DR: The experimental results show that the proposed model and algorithm can effectively solve the LSTD and provide necessary decision support for the operation of the liner alliance.

TL;DR: In this article, a review affirms the international consensus that anthropogenic underwater noise is a currently pervasive yet relatively transient form of pollution, the effects of which can be significantly reduced through effective mitigation and regulatory action.

TL;DR: In this paper, the authors analyzed decadal and regional trends in one type of shore protection method: beach nourishment, since its beginning in the U.S. nearly 100 years ago.

TL;DR: Zhang et al. as mentioned in this paper used the evolutionary game to analyze the interaction mechanism of tripartite behaviors, where the strategic space for government is non-incentive and incentive, port company is not-implement and implement, power company is noninvestment and investment.

TL;DR: In this article, the authors surveyed experts from the 32 European countries with a coastline about how their country is planning for sea level rise (SLR) and found that most coastal countries in Europe are planning for SLR, but 25% still do not.
