TC Kimi activity does influence the atmosphere and ocean dynamics around it, including in central and eastern Indonesian waters, with the highest increase in local winds occurring in Sangihe (315.8%), Gorontalo (236.3%), Seram (236.3%) dan Manado (225.8%). On the other hand, Gorontalo experienced the highest increase of significant wave height during TC Kimi active, with 921.4% increase. In this study, we analyze wave height change in central and eastern Indonesian waters before TC Kimi was active, at the peak intensity of TC Kimi, and after TC Kimi dissipated by employing Simulating Waves Nearshore (SWAN) wave model. From spatial lagged correlation analysis between wind from TC Kimi and local winds in Indonesia, we obtained 12 locations that have positive lag and correlation, namely: Denpasar, Waingapu, Rote, Majene, Gorontalo, Manado, Sangihe, Sanana, Seram, Raja Ampat, Agats dan Merauke. From time series lagged correlation, the locations that have negative lag are Denpasar (-6 h) and Rote (-1 h), those with 0 h lag are Raja Ampat and Agats, and those with positive lag are Waingapu (+ 8 h), Majene (+ 10 h), Gorontalo (+ 14 h), Manado (+ 6 h), Sangihe (+ 15 h), Sanana (+ 7 h), Seram (+ 5 h) and Merauke (+ 6 h). Surface wind analysis during the development and early phase of TC Kimi shows wind flows from Sulawesi Sea, Maluku Sea, Halmahera Sea, and Banda Sea towards the TC Kimi system. When TC Kimi approaches its strongest intensity, there are low-pressure areas (Low) that are also active, including Low in the Philippines and in the Gulf of Carpentaria, while the wind flow towards TC Kimi appears to be disconnected. Low in the Philippines and the Gulf of Carpentaria, respectively, play a role in maintaining the high waves in the northern and southern waters of Indonesia. It indicates that TC Kimi plays a role in the initial increase of wind speed in Indonesia, which is continued by the presence of Low in their respective local areas.</p></div>","PeriodicalId":100098,"journal":{"name":"Anthropocene Coasts","volume":"8 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2025-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s44218-024-00065-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142925766","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the environment can be stressed due to anthropogenic and non-anthropogenic pollutants. Plastics have been identified as a persistent pollutant that has been stressing the environment for over a few decades. Among these hazardous plastics, the accumulation of microplastics (MPs) has been identified as a growing global issue. MPs are generally defined as small pieces of plastic less than 5 mm in diameter. Considering the source, two categories are identified, primary and secondary MPs, and it has been recognized that MPs are released into the environment during plastic production, transportation, product usage, and product maintenance. Different processes including physical, chemical, photodegradation, and biological degradations tend to break plastics into MP fragments, which include MPs as well as nanoplastics. Among these degradation processes, physical degradation is prominent in the coastal regions, and chemical degradation can occur due to corrosive chemicals, acids, gases, and atmospheric pollutants, which was the case during the recent MV X-Press Pearl disaster in the Indian Ocean. Different methodologies can be applied for the pretreatment, separation, detection, identification, and quantification of MPs. Digestion of complex substances and ultracentrifugation or ultrafiltration are utilized as pretreatment methods, whereas density, magnetic and electrostatic separations, filtration, and size-exclusion chromatography are practiced as separation methods for MPs. Scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, atomic force microscopy (AFM), and mass spectrometry can be identified as the main analytical methods for MP detection. The ecological risk of MPs affects the marine environment, freshwater environment, and soil environment, ultimately influencing human health. To remediate the issue, removal methods for MPs are being developed, with currently progressing methods being physical sorption and filtration, biological removal and ingestion, chemical treatments, membrane processes, and magnetic separation. Considering the prospects, the need to conduct meta-analyses, and compare data from different studies done in various geographic regions is important, which, among other related topics such as policy development, are discussed thoroughly through this review article.</p></div>","PeriodicalId":100098,"journal":{"name":"Anthropocene Coasts","volume":"7 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s44218-024-00064-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142906075","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, information on beach accidents was collected on a recreational beach from 2004 to 2022 by searching the web or apps. The characteristics of beach accidents were therefore analysed in terms of age, gender, and activity of beachgoers. The potential factors were resolved in environmental aspects of meteorology, waves, tides, and beach morphology. Results show that beach accidents mainly occur in summer, with the highest occurrence in the afternoon and evening. The number of male beachgoers in accidents is five times higher than that of females. 90% of accidents occur when the beach is at a high-risk level for rip currents, providing evidence for the accuracy of the risk map built in a previous study. Three machine learning models, i.e., Support Vector Machine, Random Forest, and BP Neural Networks, are trained to predict beach accidents. The performances of these three machine learning algorithms are evaluated in terms of precision, recall, and F1 score. Support Vector Machine and BP Neural Networks significantly outperform Random Forest in terms of prediction. The accuracy in predicting \"safe\" and \"dangerous\" classes is approximately 80% of the Support Vector Machine model. This paper provides a preliminary study of machine learning based beach accident prediction for a specific tourist beach.

The rapid urbanization and industrialization along the east coast of India coupled with the transfer of contaminants into the Bay of Bengal through riverine systems, causing a direct impact on marine ecosystems. In the present study, an attempt has been made to understand the heavy metal distribution on shelf sediments in the western part of the Bay of Bengal to infer their source, processes, and historical changes in marine pollution. Three short sediment core samples were collected and analysed for sediment texture, organic matter, and heavy metals. Cores 1 and 2 contain a high amount of sand content, representing shallow marine with moderate to high-energy conditions, and were deposited at a recent time. Core 3 was dominated by muddy sand to sandy mud, which denotes calm sedimentation without any turbulence, and these sediments were deposited under relatively low-energy conditions. The higher concentration of organic matter in the top layers of the core indicates both marine and terrestrial input. The heavy metal contents show quite heterogeneous and variable distributions from one element to another and from one core to another. The calculated pollution indices such as Contamination Factor (CF), and Geoaccumulation Index (Igeo) and Pollution Load Index (PLI) values indicate that all the core sub-samples are severely enriched and highly polluted by Cd and moderately polluted by Pb. The increased heavy metal concentration in the upper portion of the sediment cores and moderate to considerable ecological risks indicate that these metals have been deposited in the study area for the past few decades.</p></div>","PeriodicalId":100098,"journal":{"name":"Anthropocene Coasts","volume":"7 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s44218-024-00056-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142672557","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To add to this, supporting a growing population through unsustainable anthropogenic activities for decades is considered a primary cause for deterioration of marine life, habitats, coastal and marine ecosystems and numerous ocean ecosystem services of this oceanic space. Since the health of the oceanic space is critical for survival of life of Earth, a detailed study of the impacts of a growing population on the coastal environment of the Bay is considered important. Unfortunately, since the anthropogenic activities causing this deterioration are numerous, they cannot be covered in one paper. Hence, only a select few critical anthropogenic activities causing coastal erosion, resource degradation, and marine pollution are being analysed here. The study shows that as a result of increasing population, terrestrial activities such as increasing built up area, industries, land use activities, fisheries and aquaculture, and construction of shore protection structures have resulted in reduced coastal vegetation and increased pollution of the ocean. As a result the coastal landscape is witnessing increased coastal erosion, coastal flooding and inundation, loss of vegetation and faunal communities especially fishes.
