Global studies have investigated plastic polymer distribution, but few have investigated the drivers of polymer deposition. Little work has been done in Australia, particularly on Western Australian beaches. In 2018, Wow Ecotours collected daily plastic samples from Shelley Beach on the south coast of Western Australia. A subset of 873 items was taken from five different density categories, and their polymer types were identified using Raman Spectrometry. The most abundant polymer was high-density polyethylene 45 %, followed by polypropylene and low-density polyethylene, with 33.5 % and 14 %, respectively. Onshore wind was the predominant factor driving plastic accumulation on the beach, but this did not vary significantly between polymers. The spring season has significant fluctuations in the length, mass, and area of the collected samples.

Concentrations of five metals together with hematological and morphological parameters were measured in three coastal fish species collected in two sites of the Antarctic Peninsula. Furthermore, we assessed isotopic niche widths among fish populations to better understand their trophic ecology. Nothotenia coriiceps from Fildes Bay displayed high concentrations of Fe and Cu, while those from South Bay had higher concentrations of Cd. All fish from South Bay had higher Zn levels than specimens from Fildes Bay. Effects such as biomagnification of Fe, increased fish metal levels and niche width expansion of Nothotenia coriiceps and Harpagifer antarcticus could be attributed to suboptimal environmental conditions in Fildes Bay. Our findings suggest that early warning signals in coastal Antarctic fish may be linked to increased metal bioavailability as a result of climate change and increased human pressure.

Biofouling within vessel sea chests and internal seawater systems (ISS) presents a range of operational and biosecurity issues. Marine Growth Prevention Systems (MGPS) are designed to prevent biofouling accumulation in these areas, however independent data regarding their efficacy is scarce. Sacrificial copper anode MGPS, which operate by releasing reactive copper ions, have the dominant market share. In this study, we tested copper dosages generated using cupric chloride to mimic cupric ion (Cu2+) generation by copper anode-based MGPS. We assessed the effect of copper dosages, including those recommended by MGPS manufacturers, on mortality of larval biofouling species (Ciona savignyi and Crassostrea gigas) and mature biofouling communities under various environmental conditions. Minimum inhibitory concentrations (MICs) were 2–3 orders of magnitude higher than MGPS manufacturer-reported dosages for both larval and mature biofouling. Efficacy varied with exposure regime, organic matter load, biofouling species, and organism development stage. Based on our results, short-term copper MGPS dosing according to current manufacturer recommendations appears insufficient to manage biosecurity risks within sea chests and ISS.

A coupled three-dimensional hydrodynamic water-quality model has been applied to Barnegat Bay-Little Egg Harbor Estuary, a shallow, back-barrier lagoon located along the central New Jersey coastline. The study aims to enhance understanding of phytoplankton dynamics and nutrient cycling and to quantify estuarine response to potential nutrient load management strategies. The model was calibrated with data from Spring and Summer of 2012 and adequately reproduced spatiotemporal water-quality variability, distribution patterns, trends, and gradients throughout the system.
The calibrated model was used to run scenarios for evaluating estuarine response to various nitrogen load reduction intensities. Model results show that geographically focused, variable nitrogen reductions can mitigate the effects of eutrophication and promote improvements in water quality. This study illustrates the role of modeling in developing informed management strategies, highlights complex, nonlinear responses of estuarine environments to anthropogenic influences, and demonstrates how models can be used to develop adaptive, location-specific nutrient management practices.

The monitoring capability of marine debris detection of Sentinel-2 was tested over the European seas in July–August 2023, supported by spectral discrimination criteria derived from river-debris samples. The detected aggregates of floating materials were investigated focusing on the natural aggregation processes occurring at the sea surface and on the probability to find marine debris. Limits of the current monitoring ability of Sentinel-2 have been critically reviewed suggesting which improvements can be expected from the next-generation of satellite sensors of this class. Finally, the organization of a future satellite monitoring system of marine debris detection is discussed with the aim to provide homogenous measurements of plastic pollution in European coastal areas.

The Mondego Estuary (W Portugal) experienced a process of eutrophication in the late 20th century, making it one of the most impacted systems in southern Europe. To examine its recent environmental evolution, sedimentary records were analyzed from a multiproxy approach, involving biotic, sedimentological, geochemical, physical, and radionuclide data. Results evidenced the transformation of the estuary due to anthropogenic cumulative impacts. The closure of the upstream branch triggered rapid ‘continentalization’ in the southern arm, altering the hydrosedimentary regime and favoring eutrophication. However, the middle and lower sectors exhibited stronger marine influences. Foraminiferal biota responded effectively to management interventions to improve hydrodynamics, while showing no discernible ecotoxicological responses to agricultural discharges. Pesticide accumulations patterns are shaped by natural and anthropogenic factors, with strong agrochemical fingerprints in the upper and lower sectors. The topmost 20-cm layer of sediments contain high pesticide concentrations and microplastics, posing challenges for future management and pollutant mitigation.

This study investigates the ecotoxicological effects of BDE-209, a persistent organic pollutant (POP), prevalent in Kuwait's coastal-industrial zones, on meiofaunal communities. A mesocosm experiment was conducted, exposing sediment-dwelling meiofaunal communities from sediments near Failaka Island (Kuwait) to gradient concentrations of BDE-209 (0.01–20 mg/kg) over a 4-week period. The effect on meiofaunal communities was evaluated by changes in the taxonomic composition, alpha and beta diversity metrics, and the Nematodes/Copepods (Ne/Co) ratio. Our findings reveal that BDE-209 exposure significantly reduced alpha diversity and induced shifts in the community structure, favouring resilient taxa such as nematodes. The increasing Ne/Co ratio underscores structural changes and highlights the pollutant's potential to disrupt sedimentary ecosystem functions. Temporal analyses confirm the persistence of BDE-209 in sediments despite partial degradation, reinforcing its classification as a POP with long-term ecological risks. This study provides valuable insights into the responses of meiofaunal communities to POPs like BDE-209, demonstrating their efficacy as bioindicators for sediment quality. By integrating meiofaunal biomonitoring metrics with mesocosm experiments, this research provides a robust method for assessing the ecological impacts of BDE-209, particularly in regions lacking regulatory frameworks. It also raises awareness of the broader implications of POPs in marine ecosystems. These findings highlight the urgent need for enhanced monitoring programs and stricter regulations to mitigate PBDE contamination in marine ecosystems. Future research should focus on field-based validation of mesocosm results and investigate the interactive effects of BDE-209 with other pollutants to better understand its cumulative ecological impact.

Cephalopods are ecologically and economically important species and play a key role in marine ecosystems. However, knowledge about the presence and effects of microplastic (MP) ingestion in this taxonomic group is still limited.
The present research aimed to explore plastic ingestion and health status in the cuttlefish, Sepia officinalis, from the Gulf of Patti in the southern Tyrrhenian Sea, for the first time. In addition, this helps in assessing the MP pollution risks in the area. Plastic occurrence and characterization were investigated, and Le Cren's relative condition factor (Kn) calculated as an index of health status. MP concentrations and polymer hazardous were also used to preliminarily detect the environmental risk.
High MP occurrence values (%O = 69) were recorded in this commercially important cephalopod species from the Mediterranean Sea suggesting that the habitat, feeding habits and digestive system (morphology and function) play an important role in affecting the occurrence and distribution of MP in S. officinalis. Absence of a clear correlation between MP ingestion and Kn in this study does not exclude the possibility of more subtle or long-term impacts of plastic on common cuttlefish health. Preliminary risk assessment confirms that the study area is subject to MP pollution and hazardous polymers.
The data from this study suggests that common cuttlefish have the potential to be usefully assessed as a bioindicator for Mediterranean scale plastic pollution monitoring. We propose the addition of this species to the current monitoring programs such as the ones performed within the Marine Strategy Framework Directive.

International biodiversity agreements aim to expand protected areas by up to 30 %, including areas beyond national jurisdiction. The high seas' extent, shared governance, and limited biodiversity data challenge the identification of large-scale areas to be protected. This study uses seascapes defined from satellite data as proxies for biodiversity in the Atlantic high seas to assist in preliminary designations of protected areas. Seascape's extent is compared with modelled distributions of phytoplankton groups, fish species, and endangered species to assess their biodiversity representativity. Furthermore, the study addresses trade-offs between protecting 30 % of each seascape, covering endangered species distribution, and main human activities in high seas (shipping and fishing). Marine traffic lanes are defined where there is currently more activity, redirecting other activities in the centroid of the seascapes to these lanes. This strategy protects 21 %, 35 %, 44 %, and 48 % of the habitat of the considered endangered species, while displaced human activity ranges from 3 % to 7 % for shipping and up to 4 % for fishing. The size of areas with high concentrated noise increases by 7.8 %, affecting all trophic levels, but areas without activities with only propagated noise increase by around 78.9 %. These results suggest that protecting at least 30 % of each seascape with activity lanes is a good prioritization starting point for high seas protection, which can be redefined later based on the presence of rare species or key habitats and socio-economic factors agreed with stakeholders within a systematic spatial planning approach.

Microplastics (MPs) are considered one of the main pollution issues on the planet. This study constitutes the initial assessment of MPs on sandy beaches in Cuba. Four beaches with different characteristics and anthropogenic activities were selected on the north and south coasts of the island's central region. MPs (0.3–5 mm) were identified at three out of four beaches studied, with 0–196 MPs m2 (0–47 MPs kg−1). The MPs found on the south coast, Tetas de Tomasa Beach in Cienfuegos Bay, exhibited the highest average abundance, 95 ± 61 MPs m2, followed by Rancho Luna with 3 ± 4 MPs m2. On the north coast, Las Gaviotas Beach showed an average abundance of 2 ± 4 MPs m2, and no MPs were found at Cañón Beach. Fragments were the main morphology (55 %), while the most prevalent colors were white/transparent (65.2 %) and blue (19.4 %). Polyethylene was the predominant synthetic polymer (52 %), followed by polypropylene (32 %) and polystyrene (14 %).
