There is great strength, however, in combining these disparate datasets to make inferences about broader patterns and therefore inform the discussion about the impacts and extent of plastic ingestion by providing data for sparsely sampled taxa. Here we summarise plastic ingestion records collected from seven seabird species in Western Australia and New South Wales, Australia to provide a baseline and updates on exposure of these species to plastics. For most of the species included in our assessment, this is the first data available regarding plastic ingestion in more than two decades. Very low rates of plastic ingestion were observed in Great-winged Petrels <em>Pterodroma macroptera</em>, Little Shearwaters <em>Puffinus assimilis</em>, and Providence Petrels <em>Pterodroma solandri</em> with only the adult and fledgling Wedge-tailed Shearwater <em>Ardenna pacifica</em> and Sable Shearwater <em>Ardenna carneipes</em> containing moderate amounts of plastic (&gt;8 % prevalence). Black-winged Petrels <em>Pterodroma nigripennis</em> and Masked Boobies <em>Sula dactylatra</em> did not contain any ingested plastic. These data were collected and reported using standardised methods to ensure the information can be used as a benchmark against prior and future plastic ingestion studies. Syntheses such as these provide valuable knowledge for regions or species with limited data, and in doing so, begin to reveal patterns of plastic pollution and its relevance to seabird conservation.</div></div>","PeriodicalId":18215,"journal":{"name":"Marine pollution bulletin","volume":"214 ","pages":"Article 117757"},"PeriodicalIF":5.3,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143520322","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, the recent construction of a 36 km-long causeway across the Bay and related land reclamation projects has disrupted the Bay's natural flushing processes, allowing pollutants and excess nutrients to accumulate more readily. However, the impact of these new infrastructures on the Bay's circulation patterns and water renewal capacity remains unquantified. Here, we use the multi-scale ocean model SLIM to simulate the fine-scale flow patterns in Kuwait Bay and evaluate water residence time distribution, focusing on its spatial and seasonal variability. By further comparing pre- and post-construction scenarios, we quantify the causeway's influence on Kuwait Bay's hydrodynamics and flushing properties. We find a complete renewal of the Bay within 150–320 days, driven by significant spatial and seasonal variations in water residence time, largely influenced by the prevailing winds and strong tidal flows interacting with the Bay's shallow depths. The introduction of the artificial structures extends the average residence time by only 1.29 days (+3.49 %), but with significant local variations ranging from −66 to +56 days, underlining the causeway's role as a physical barrier, and amplifying the risks of water quality degradation in some regions.
