RSL data were collected by the Brazilian Institute of Geography and Statistics (IBGE) and the Oceanography Institute of the University of São Paulo (IOUSP), on several geographical locations along the Brazilian coast, along with information from Global Positioning System (GPS) data. These data were used to calculate the trends of mean sea level, seasonal variability and interannual variability. The tidal constituents were computed using harmonic analysis, for the analyzed stations. The results, referenced to the Brazilian Vertical Datum (BVD) established in 1949–1957, indicate rising rates above the global mean RSL, based on tide gauge records spanning from 1948 to 2020, depending on the location. The observed values are 4 ± 0.8 mm/year in Imbituba, 4.3 ± 0.2 mm/year in Cananéia, 2.2 ± 0.027 mm/year in Ilha Fiscal, 3.1 ± 0.5 mm/year in Salvador, 2.4 ± 0.3 mm/year in Fortaleza, and 3.4 ± 0.32 mm/year in Santana. These trends, influenced by global factors and local conditions, such as land subsidence and climatic events like ENSO, emphasize the urgent need for continuous monitoring of the coastal zones and the implementation of adaptive measures.

The evolution of modern propellers began with the discovery of steam power and has led to complex engineering solutions that enhance the efficiency of maritime transport. The choice of propeller has a critical impact on a ship's performance. This paper aims to determine the most suitable propeller systems for vessels such as tankers, dry cargo vessels, chemical tankers, container vessel operating at speeds above 10 knots. The types of propellers analyzed include fixed pitch propellers, controllable pitch propellers, ducted propellers, Grim Vane wheels, propeller-stator systems, and Z-Drive units. Every propeller system is assessed according to a number of parameters such as high thrust power, high maneuverability, initial investment cost, maintenance and repair costs, construction ease or difficulty, operational or usage ease or difficulty, breakdown risk during the voyage, and an increase in total propulsion efficiency. The selection process utilizes the intuitive fuzzy TOPSIS method, which ranks alternatives based on their similarity to an ideal solution. The IF-TOPSIS method was applied to determine the most suitable propeller types among six alternatives. The closeness scores were as follows: Fixed Pitch Propeller (0.120), Controllable Pitch Propeller (−0.028), Z-Drive Units (−0.073), Propeller Stator System (−0.080), Ducted Propeller (−0.085), and Grim Vane Wheel (−0.162).

In this research, a typical coastal commercial fish, Silver pomfret <em>Pampus argenteus</em> in the East China Sea, was selected as a case study to preliminary explore the performance. Based on fisheries statistical data and independent survey data, multiple methods were used to understand the life history traits and population dynamics of Silver pomfret. The growth, maturity and mortality characteristics have all greatly changed, i.e smaller size and faster growth, in recent years compared with the previous period. Two length-based models LBSPR and LIME estimated different parameter values, but both suggest an overfished status of Silver pomfret in the East China Sea in 2020, with high fishing mortality and low spawning potential ratio. The catch-based surplus production models BSM and SPiCT, estimated an unrealistically healthy situation of this stock. Considering many other influencing factors affecting the population and fishery dynamics of Silver pomfret, the population has not yet recovered, despite the implementation of multiple management strategies that have reduced fishing pressure. We also strongly advocate for species-specific management of Silver pomfret, e.g. increasing minimum landing size by 10 g and 1 cm, and setting total allowable catch as the 90 % of the three-year average historical catch.</div></div>","PeriodicalId":21070,"journal":{"name":"Regional Studies in Marine Science","volume":"89 ","pages":"Article 104299"},"PeriodicalIF":2.1,"publicationDate":"2025-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144480350","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
