The present study provides the first baseline assessment of marine litter distribution, composition, and ecological implications in seven macroalgal-dominated sites across the Andaman Islands, India. A total area of 8400 m² was surveyed using standardized transect-based visual assessments, documenting 2817 litter items (126.56 kg) comprising plastics, glass, and metals from both consumer and fishing-related sources. Plastics accounted for 79% of litter composition and 89% of litter mass, underscoring their pervasive presence. Litter density ranged from 0.11 to 0.69 items m⁻², with island sites exhibiting significantly higher accumulation compared to offshore diurnal stations. Environmental quality indices (CCI, GI, CEI, PAI, HII, and ERI) revealed elevated ecological risk at South Reef and Anderson Islands, characterized by higher contamination loads and hazard levels. Cluster analysis further distinguished sea-based from land-based litter, highlighting dual-source pathways. Marine litter represents a potential ecological risk to seaweed habitats through the accumulation of hazardous and entangling litter. Given the ecological and socio-economic importance of seaweed habitats in tropical island systems, these findings highlight the need for improved waste management, targeted mitigation, and long-term monitoring. This study provides a comprehensive baseline assessment of marine litter in seaweed ecosystems of a tropical island archipelago, establishing a benchmark for future monitoring, comparative studies, and evidence-based management.</div></div>","PeriodicalId":56021,"journal":{"name":"Anthropocene","volume":"55 ","pages":"Article 100573"},"PeriodicalIF":4.7,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148934795","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To overcome this gap in knowledge, we use a U-Net convolutional neural network to segment trawl marks across approximately 1069 km² of seafloor in the German sector of the Western Baltic Sea. The model was trained and applied to open-source bathymetric data collected between 2016 and 2025 with a resolution of 1 m. Trawling intensities vary substantially in space and over time, as evidenced by time-lapse bathymetric data for the Fehmarn Belt area. Here, repeated surveys of a Marine Protected Area (MPA) in 2024 and 2025 confirm seafloor regeneration timescales of approximately one year. Within the MPA, trawl mark densities and AIS-derived fishing effort both increased from 2024 to 2025, indicating continued trawling activity despite a bottom trawling ban that entered into force in 2025. Circular untrawled zones in Mecklenburg Bay, often with diameters of more than 500 m, coincide with seafloor pockmarks indicating localized fluid seepage. We attribute these untrawled zones to fishermen avoiding the pockmark depressions which pose a risk to bottom-contact gear. Trawl marks are morphologically healed in areas with intense commercial ship traffic.

We investigated the Ussuri (Wusuli) River basin in northeast China by analyzing major ions, DIC, DOC, POC, δ¹³C_DIC and <em>p</em>CO₂, and examined their linkages with catchment land-use composition. Land-use gradients were distinct: upstream sub-catchments were dominated by farmland (87%), middle reaches by urban areas (17%), and downstream reaches by forest (26%). Cropland-dominated sub-catchments exhibited higher mean DIC (96.6 ± 26.5 mg L⁻¹) and <em>p</em>CO₂ (3065.2 ± 2242.1 μatm), alongside more negative δ¹³C_DIC (–10.47‰). In contrast, forest- and wetland-influenced tributaries had lower DIC (65.2 mg L⁻¹) and more positive δ¹³C_DIC (–9.93‰), reflecting stronger soil-CO₂ inputs, in-stream processing, and CO₂ outgassing. Nutrient and major-ion distributions aligned broadly with agricultural and urban inputs, though land-use correlations were modest and should be viewed as spatial associations rather than causal evidence. Cropland proportion correlated positively with POC and C/N ratios, indicating enhanced export of soil organic matter. DOC concentrations were elevated in forest-dominated catchments compared to urban-cropland ones, suggesting land-use change modulates biogenic carbon mobilization and transport. Collectively, our findings demonstrate that anthropogenic land-use intensification acts as a primary driver reshaping both the concentration and isotopic composition of riverine carbon exports in this cold-temperate system.

Using sedimentation rates from 48 major dams and sediment load data from 23 gauging stations, we find that between 1969 and 2013, sediment load decreased by 115 Mt/a, while reservoir storage increased by 101 Mt/a. This near-complementary relationship suggests that a previously well-connected fluvial system has been disrupted by dam construction. In sub-basins with minimal dam influence, sediment load changes are lesser or insignificant, reinforcing the spatial coherence of this connectivity. Importantly, this connectivity extends all the way to the delta, where only 20% of the incoming sediment is retained.

However, evidence connecting heat exposure with suicide is largely based on short-term studies within individual countries, limiting understanding of global patterns and social disparities. This study examined associations between heatwave temperature anomalies and suicide mortality across countries with different socioeconomic contexts. We conducted a country-level panel analysis using harmonized suicide mortality records from the World Health Organization for 99 countries from 2000 to 2019, combined with gridded climate reanalysis data. Population-weighted country-year indicators of heatwave apparent temperature anomalies were linked to national suicide rates. Heatwave temperature anomaly is defined as the deviation of heatwave-day apparent temperature from the long-term (1990–2019) local climatological mean, capturing the intensity of extreme heat relative to local climate conditions. Poisson fixed-effects models estimated associations while accounting for country characteristics and long-term trends. Stratified analyses assessed heterogeneity by gender, age group, and socioeconomic vulnerability, and exploratory analyses examined national patterns of mental disorder burden. Higher heatwave apparent temperature anomalies were associated with increased female suicide mortality in middle-income countries. An 1 °C increase in apparent temperature during heatwaves corresponded to a 2.3% rise in female suicide rates. Associations were strongest among women aged 45–64 years and in countries with higher levels of vulnerable employment, representing approximately 0.33 billion and 0.24 billion people globally. National patterns of bipolar disorder burden were consistent with a potential mental-health pathway linking heat exposure and suicide vulnerability. These findings suggest that extreme heat may influence population-level suicide mortality, particularly in socially vulnerable settings, providing global empirical evidence supporting the association between heat exposure and suicide risk, and highlighting the need for integrated heat-adaptation and suicide-prevention strategies.</div></div>","PeriodicalId":56021,"journal":{"name":"Anthropocene","volume":"54 ","pages":"Article 100554"},"PeriodicalIF":3.9,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148184892","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results demonstrated that magnetic minerals in sediments of the two lakes were dominated by detrital magnetite, coupled with a minor contribution of high-coercivity minerals. The conventional parameters indicative of magnetic material concentration (χ_lf, χ_ARM, and SIRM) and grain size (χ_fd (%), SIRM/χ_lf) indicated a notable intensification of agricultural activities and the presence of industrial activities in catchments of the two lakes since the 1960s.

Interestingly, the isothermal remanent magnetization ratio (S₋₃₀₀), a magnetic parameter indicating the relative proportion of high- to low-coercivity magnetic minerals, markedly increased in post–1960s sediments of both lakes, and its values were linearly correlated with catchment GDP and population data.
