Hainan province of China, adjacent to the western North Pacific, is vulnerable to typhoon hazards. In this study, we constructed 65 typhoons using the Jelesnianski model to force the Advanced Circulation (ADCIRC)-Simulating Waves Nearshore (SWAN) coupled model and reproduced typhoon waves and surges, then assessed their extreme values around Hainan under 20-, 50-, and 100-year return periods. Taking Sanya station as an example, we further conducted joint risk analysis via considering bivariate and Trivariate hazard factors. The relative errors of modelled wind speed (V), significant wave height (SWH), and storm surge (S) are less than 10 % compared to in-situ observations. Using the Gumbel function, extreme values of V, SWH, and S under the 100-year return period around Hainan province can exceed 40 m s<sup>−1</sup>, 15 m, and 2 m. After Kolmogorov test, the Gumbel-Hougaard Copula function was used to estimate bivariate and trivariate joint probability distributions at Sanya station and calculate the “OR” return periods of different joint events. The “OR” return period of three factors at the Sanya station under the 100-year extreme value is 48.79 years, indicating a high probability of simultaneous occurrence on account of their correlation. This study focused on the complex topography surrounding Hainan Island and utilized a coupled model to compensate for the limitation of synchronous observational data in typhoon joint risk analysis.</div></div>","PeriodicalId":50056,"journal":{"name":"Journal of Sea Research","volume":"205 ","pages":"Article 102587"},"PeriodicalIF":2.1,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143855158","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First, we described inter- and intra (seasonal) annual patterns. Then, daily patterns in stings and monthly jellyfish abundances, by means of a model selection strategy, were connected with daily and monthly environmental drivers (zooplankton biomass, Sea Surface Temperature, SST, wind intensity, as well as climatic indices related to El Niño and La Niña events). We detected a strong seasonal trend in the number of jellyfish stings, with larger values in spring and summer relative to autumn and winter. <em>Physalia physalis</em> and <em>Velella velella</em> appeared during winter, which was also revealed by the model selection approach on the effect of environmental predictors (SST, in particular) on their abundances. In contrast, <em>Pelagia noctiluca</em> -the most abundant species - was present all year round, with the summer months as those with the highest abundances. There was a significant correlation between the daily number of stings and the daily presence of <em>Pelagia noctiluca</em> over time. In brief, the occurrence of the three jellyfish species, in the study area, is seasonally partitioned, with SST over time as the most relevant environmental predictor of both the number of stings and the abundances of the three jellyfish species.</div></div>","PeriodicalId":50056,"journal":{"name":"Journal of Sea Research","volume":"205 ","pages":"Article 102584"},"PeriodicalIF":2.1,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143855062","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, it examines the policy implications of varying the deployment of Automated Guided Vehicles (AGVs) and inspection platforms to optimize throughput and minimize operational delays during crises.

Here we aimed to 1) compile records on the distribution and area extent of seagrass meadows in the four wetlands of the Algarve region (southern Portugal) with historical occurrence of seagrasses, based on a systematic review, and 2) update the distribution maps and area extent of seagrass meadows in this region using a combination of manual and machine learning mapping techniques. The systematic review showed a general lack of data on the distribution of seagrass meadows in the Algarve, with patchy information at different times and using incomparable mapping techniques.

In the Ria de Alvor, some sparce scattered patches of seagrass were observed in the intertidal zone, while no seagrass was found in the Arade estuary. The total extent of seagrass in the Algarve region was estimated at 1231 ha, with nearly all (99 %) occurring in the Ria Formosa, where 85 % was intertidal.

This study evaluates the effectiveness of the nuclear 28S ribosomal RNA (28S rRNA) and mitochondrial cytochrome <em>c</em> oxidase I (COI) genes in identifying copepod species from the Northwest Pacific.

This study develops a three-tier supply chain model incorporating governmental authorities, port operators, and dual shipping companies to examine shore power adoption strategies. Through Nash equilibrium analysis, we investigate the efficiency of shore power utilization under both subsidized and non-subsidized scenarios in order to find the resilience solution for the relevant stakeholders. The findings reveal that in the absence of government intervention, shipping companies' equilibrium strategies are primarily determined by the relative costs of conventional fuel and shore power, leading to potential Prisoner's Dilemma situations.
