Yet, many coastal lagoons face growing threats from salinisation and eutrophication driven by climate change and human activities. Climate-induced salinisation arises from multiple factors, including elevated temperatures, enhanced evaporation, reduced precipitation and freshwater inputs, and rising sea levels that trigger upwelling and direct saline intrusion to lagoons. These fragile and complex environments offer valuable models for understanding how coastal zones worldwide respond to global change. This review examines how salinity shapes microbial community composition and biogeochemical processes in hypersaline lagoons. Elevated salinity reduces microbial α-diversity, favouring salt-tolerant taxa and restructuring nitrogen and carbon cycling. Key processes, such as nitrification, denitrification, and methane production are disrupted, altering nutrient retention, organic matter decomposition, and greenhouse gas emissions. Increased salinity also intensifies eutrophication, creating positive feedback loops that weaken ecosystem health and reduce carbon sequestration. Microbial communities exhibit adaptive responses, including osmoregulatory strategies and horizontal gene transfer, which support resilience under rising salinity. By synthesising evidence on these interactions, the review illustrates the importance of understanding microbial-mediated processes to inform the conservation and management strategies for coastal lagoons under climate and anthropogenically-induced salinity change.</div></div>","PeriodicalId":11483,"journal":{"name":"Earth-Science Reviews","volume":"266 ","pages":"Article 105150"},"PeriodicalIF":10.8,"publicationDate":"2025-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143898697","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a potential ERW material, carbonate is characterized by rapid dissolution kinetics and is environmentally friendly. However, the CDR potential, cost, and effectiveness of carbonate-based ERW implementation are not well explored. Using a carbonate equilibrium equation, and the CMIP6 (Coupled Model Intercomparison Project Phase 6) GCM (Global Climate Model) and LCA (Life Cycle Assessment) models, here we analyze the CDR potential, carbon footprint, and cost of a carbonate-based RW strategy (so-called enhanced carbonate weathering, ECW). We estimated that the current global potential carbon removal (PCR) of ECW could reach ∼2.66 (Representative Concentration Pathway (RCP) 4.5) and ∼ 2.82 (RCP8.5) Gt CO<sub>2</sub> a<sup>−1</sup>, and that the cumulative CO<sub>2</sub> removal by the end of this century could reach 241.32 Gt CO<sub>2</sub> a<sup>−1</sup> (RCP4.5) and 246.64 Gt CO<sub>2</sub> a<sup>−1</sup> (RCP8.5). This could potentially neutralize ∼23.11 % (RCP4.5) and ∼ 23.62 % (RCP8.5) of future global carbon dioxide emissions. We also found that the global CDR potential of ECW can respond sensitively to global environmental perturbations, and that the CDR potential in the future will generally increase in high-latitude regions due to global climate change. We compared the cost of enhanced silicate weathering (ESW) with ECW implementations for seven major countries with high CDR potential and found that the cost per mol of CO<sub>2</sub> removal by ECW is 1.33–2.07 times lower than that for ESW. While the stability of dissolved inorganic carbon (DIC) is debated in many studies, we suggest that the new approach represented by ECW should consider the role of aquatic photosynthesis. Overall, the biological pump induced by aquatic photosynthesis is significant for increasing the carbon storage of ECW in inland waters. For future ERW implementation, we stress the need to develop an Enhanced Coupled Carbonate Weathering plus aquatic photosynthesis strategy (ECCW) that can both offset the negative effect of CO<sub>2</sub> degassing and also increase the total CDR of ECW to a greater degree than expected. ECCW remains in the developmental stage, and its large-scale implementation requires further laboratory and field experiments to determine its CDR-efficiency and environmental effects and risks.</div></div>","PeriodicalId":11483,"journal":{"name":"Earth-Science Reviews","volume":"266 ","pages":"Article 105149"},"PeriodicalIF":10.8,"publicationDate":"2025-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143882901","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to understand and quantify the processes regulating sediment generation and transfert in the uphill catchments of the Sierra Nevada de Santa Marta (SNSM) - the world's highest coastal range within subtropical regions. We tackle the complex task of quantify the role of external forcings on sediment production in 17 drainages basins within the SNSM by challenging conventional assumptions and introducing new compositional models. Our research significantly expands the existing knowledge base on compositional modelling by presenting a systematic framework for characterizing sediment generation, particularly focusing on the influence of tectonics, climate, lithological factors, and analytical reliability. We produced a robust compositional database encompassing optical petrography (11,463 grains), Raman heavy mineral analysis (44,782 grains), detrital geochronology (apatite, titanite, and zircon – 6378 grains), apatite (1159 grains) and titanite (1571 grains) geochemistry, and bulk-rock and silt-clay geochemistry.We present a novel linear log-ratio (end-member) sediment generation model calibrated on geomorphological parameters as connectivity and erodibility, facilitating the evaluation of sediment generation capacities from metamorphic, plutonic, and volcanic lithologies. Sediment texture and composition vary remarkably from drainage to drainage, providing the elements to model both the relative (by comparing lithologies) and absolute capacity of drainage lithologies to produce sediments, in the settings of the SNSM. Our results reveal significant variations in sediment texture and composition among drainages, providing insights into both the relative and absolute capacity of different lithologies to produce sediments in the SNSM setting. We found that metamorphic rocks produce higher amounts of sand compared to plutonic and volcanic lithologies, while the sediment generation capacity of plutonic rocks is up to 9 times higher than that of volcanic lithologies. In mixed drainages with equal proportions of metamorphic and other rocks, metamorphic detritus can constitute up to 60 % of sand compositions. Surprisingly, geomorphological parameters like structural connectivity and erodibility played a minor role in sediment generation in this tectonic setting, contrary to findings in other regions.

In rifts developed in relatively cold lithosphere (e.g. East African Rift) inherited fabrics are predominantly old (Precambrian), widely separated in time from rifting. Rift location is strongly linked to where lithospheric mantle strength is reduced by deep mantle processes. Conversely, in Thailand (SE Asia) Cenozoic rifting developed in hot lithosphere (upper plate of major subduction zones), inherited fabrics comprise a highly diverse range of types (folds, thrusts in Phanerozoic sequences, gneiss domes, granite plutons, metamorphic foliations, strike-slip faults) that formed primarily during the Triassic (Indosinian Orogeny), Late Cretaceous and Paleogene. The orogenic development of gneiss domes in Thailand has parallels with Caledonian structures below the northern North Sea rifts. Rift location is controlled by the area of weakest crust, i.e. the Indosinian Paleotethys suture zone. Rift mode in Thailand varies from wide to narrow to core complex not only in response to crustal conditions (temperature, thickness), but also to local magmatism and fabric inheritance (major Indosinian detachment zones). The wealth of fabrics in Thailand influenced the location, dip direction, dip value, strike orientation, propagation and linkage history, fault length-displacement characteristics, fault population size distribution and map-view patterns of normal faults. Fabric influence on Thailand's rift basins is important to identify for a variety of reasons including: 1) as an extra factor to crustal thickness and geothermal gradient that influences rift mode, 2) as a major control on rift location, 3) as means of explaining atypical fault patterns in rift basins, and thereby supporting an extensional origin, rather than an escape-tectonics related strike-slip origin, 4) as a major influence on the characteristics of individual rift basins and how structures of economic importance have developed. 5) Causing fault populations to evolve in a variety of ways during the rift initiation phase.

Despite the impact of BCEs as natural climate solutions, the mechanisms responsible for carbon retention have not been clearly summarised, limiting our chance to manage BCEs for maximum carbon storage. Here, we explore a great mystery of the blue carbon cycle by reviewing existing published literature: Why is some coastal carbon remineralised into CO<sub>2</sub> and CH<sub>4</sub> by microbes within seconds/min while other carbon escapes microbial attack and becomes sequestered for millennia? The answer to this question will help predict and manage the global blue carbon cycle. We find that microbial communities are fundamental drivers of carbon mineralisation in BCE sediments, with their metabolic pathways dictating the fate of sequestered organic matter. Contrary to earlier notions, microbial diversity and composition are shown to significantly impact carbon stabilisation, with distinct microbial taxa targeting different organic compounds. Furthermore, anthropogenic disturbances such as habitat alteration and eutrophication can disrupt microbial communities, leading to increased carbon mineralisation and CO<sub>2</sub> and CH<sub>4</sub> emissions. Environmental parameters such as temperature, salinity, and nutrient availability also exert considerable influence on carbon stability in BCEs. Changes in these factors can alter microbial activity and the degradation rate of organic matter, highlighting the importance of understanding their additive and synergistic effects. For instance, warming combined with oxygen exposure due to habitat disturbance can amplify microbial carbon mineralisation, particularly in submerged BCEs like seagrass beds. Future research directions include characterising carbon at molecular levels, understanding region-specific drivers of carbon stability, and prioritising conservation efforts based on physiographic and geomorphologic settings. This review underscores the need for a holistic approach to BCE management, considering both microbial processes and environmental factors.

Conversely, in foreland basins, EGMS maps show higher values than GNSS data, which reflect regional interactions between ongoing tectonics and compaction. Local discrepancies between EGMS and GNSS in industrialized areas are attributable to industrial activities, as evidenced by the EGMS subsidence rates (8 mm/yr) observed in Ravenna, which exceed regional long-term estimates (0.8 mm/yr).
