A global scale granitoid belt can be readily identified from Sikhote-Alin in the north all the way to Northwest Borneo and to the Qiangtang terrane, as representing a giant magmatic arc system in response to the direction change of the subduction of the Izinagi plate and the Indian-Australian plate at ∼100 Ma. This global subduction/magmatic system was displaced in the Early Cenozoic as the result of India-Asian collision, followed by the development of the escape tectonics characterized by strike-slip fault systems. The subsequent rifting further broke and dispersed the granitoid belts into fragments to the present locations in the Greater Southeast Asian tectonic realm.</div></div>","PeriodicalId":11483,"journal":{"name":"Earth-Science Reviews","volume":"259 ","pages":"Article 104970"},"PeriodicalIF":10.8,"publicationDate":"2024-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142655368","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}

While this &gt;1.6 million km-long network has been designed to be highly resilient, subsea cables can be damaged by a number of natural hazards that occur across all water depths in the ocean. Here, we explore the diversity of natural hazards that can damage cables, considering a broad frequency-magnitude spectrum. This paper is the first global perspective of actual and potential hazards affecting cables. As such, it is an accessible overview of the regional variability and complexity of hazards. Relatively rare and extreme events, such as super typhoons, submarine landslides or associated turbidity currents and volcanic eruptions, can synchronously cause widespread damage to multiple systems, in some cases disconnecting entire countries or dramatically slowing data traffic. We show that damage is rarely linked to an initial event, instead arising from cascades of processes that can lag by years. Not all instances of cable damage that relate to natural processes are linked to extreme events. We show that much smaller intensity meteorological and oceanographic processes such as storms and continuous seafloor currents that have been overlooked by previous studies can also damage subsea cables. New analysis of past instances of cable damage reveals that a significant proportion of previously unattributed faults may relate to such low-level but sustained impacts. It is these hazards that are most likely to change in frequency and magnitude in response to ongoing climate change but are also more predictable. Through mapping of exposure to these different hazards, we identify geographically-constrained hazard hotspots and identify various mitigation measures to enhance the evidence base and further strengthen subsea telecommunications network resilience.</div></div>","PeriodicalId":11483,"journal":{"name":"Earth-Science Reviews","volume":"259 ","pages":"Article 104972"},"PeriodicalIF":10.8,"publicationDate":"2024-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142655371","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on an extensive review of published literature, current knowledge of floodplain lakes and links between hydrology and ecology are summarized and synthesized. River-lake interactions determine hydrological conditions in floodplain lakes, with high spatial heterogeneity influenced by topography, geophysical properties, and climate. Seasonal fluctuations in water level and hydrological connectivity affect the community structure of aquatic organisms and biogeochemical processes. The interplay of floods and terrain shapes vegetation dynamics. Hydrological regimes sustain the quantity and quality of habitats, along with food resources for waterbirds and other organisms. Although certain species have adaptive capacities to changing hydrology through life history strategies, behavioral modifications, or physiological adjustments, long-term pressures from reservoir construction, intensive land use, and other human activities appear to be inducing cumulative, non-linear impacts that may push these ecosystems towards critical thresholds. Sustained pressures increase the risk of regime shifts, threatening ecosystem functionality. Current research often overlooks the complex interactions and feedbacks within ecosystems, leading to uncertain predictions regarding species resilience and ecosystem function. Existing methods are insufficient for fully integrating both short-term disturbances and long-term pressure. Advancing understanding of species adaptations across different temporal scales remains a priority, highlighting the need for more comprehensive frameworks for biodiversity conservation that effectively account for changing environment. Future efforts should focus on comprehensive in-situ monitoring and observation strategies, jointly with the application of advanced mathematical models, to enhance our understanding of ecology of floodplain lakes.</div></div>","PeriodicalId":11483,"journal":{"name":"Earth-Science Reviews","volume":"258 ","pages":"Article 104967"},"PeriodicalIF":10.8,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142561351","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}

The primary methods for evaluating these parameters include direct core observations, experimental testing, and indirect evaluation techniques. Since its introduction, geophysical logging has been used to evaluate and invert reservoir parameters owing to its wide coverage. With an increasing focus on unconventional natural gas reservoirs, more refined reservoir evaluations and multiparameter analyses are required for their development to address the complex and microscopic models differing from those of the conventional petroleum reservoirs. Geophysical logging is important in several unconventional fields. Machine learning (ML) was used in unconventional gas reservoirs as an effective method to establish relationships between parameters and logging features. However, the accuracy of evaluating storage layers using a single ML method is limited. Studies focusing only on algorithm updates and indicator values are problematic in terms of interpretability and production applications. A need to standardize the use of algorithms and introduce validation comparisons such as geological methods is evident. In this study, we reviewed ML algorithms and models commonly used for logging inversion applications. The current research status and issues were analyzed for different unconventional gas reservoir parameters. Our findings emphasize the importance of combining geological and other methods for logging inversion using ML. We also used the random forest algorithm to accurately predict the reservoir porosity, gas content, coal structure, and macrolithotypes. Combined with established permeability and vitrinite reflectance models, factor analysis was used to comprehensively analyze and evaluate the coalbed methane reservoirs in the study area. In our assessment of the challenges and future work on ML-based inversion, we observed a clear advantage for ML algorithms under geologically validated methods and experimental control. ML has great potential for optimizing the application of logging inversion for unconventional reservoir parameters.</div></div>","PeriodicalId":11483,"journal":{"name":"Earth-Science Reviews","volume":"258 ","pages":"Article 104969"},"PeriodicalIF":10.8,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142573283","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}

However, our understanding remains limited regarding which processes―air-sea exchange, ocean circulation, and the biological pump―primarily influence the spatial dynamics of the oceanic carbon cycle. To address this knowledge gap, the present study compiles global stable carbon isotope (δ¹³C) records from various sources, including shallow and deep planktic, along with epifaunal and infaunal benthic foraminifera. The synthesis reveals a total increase of 0.37 ± 0.05 ‰ in marine δ¹³C values since the last glacial maximum. Of this increase, 68 ± 5 % is attributed to the response of the oceans in the southern hemisphere, while 32 ± 4 % is attributed to the northern hemisphere. By analyzing the difference between planktic and benthic foraminifera, a decreased vertical δ¹³C gradient (δ¹³C_sp–sb) is observed during the last deglaciation, indicating rapid carbon exchange between surface and deep waters during deglaciation. Additionally, the offset between the epifaunal and infaunal δ¹³C (δ¹³C_sb–db) provides insights into changes in productivity and bottom water oxygenation. Overall, the global synthesis suggests that the δ¹³C variation is largely controlled by ocean circulation in the northern hemisphere and at higher latitudes of the southern hemisphere, while primary production significantly influences subtropical regions. Furthermore, the δ¹³C confirms that the rise in atmospheric CO₂ during the first phase of Heinrich Stadial 1 (HS1) resulted from reduced primary production in subtropical regions along with strong ventilation in the second phase of HS1. Interestingly, the δ¹³C variations during the Younger Dryas (YD) suggest strong ventilation without evident changes in primary production. This four-dimensional dataset provides valuable insights into the transient changes in the ocean carbon cycle during deglaciation.</div></div>","PeriodicalId":11483,"journal":{"name":"Earth-Science Reviews","volume":"258 ","pages":"Article 104966"},"PeriodicalIF":10.8,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142552466","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}

However, the specific mechanisms underlying the interplay between these geospheres still remain unclear. Here, we take the eastern Himalayan syntaxis, the most typical region undergoing ferocious geosphere interplay on the planet, as our primary research area. We incorporated a topography-dependent precipitation model into traditional geomorphological-thermomechanical modelling and conducted over 200 experiments to investigate the interplay between climate, tectonics, and surface processes during the evolution of the orogenic wedge. The results show that a distinct type of orogenic wedge emerges when the convergence rate and average precipitation fall within specific ranges determined by the crustal geothermal field. Within this type of orogenic wedge, a sustained, stationary, localized and relatively rapid erosion process can be established on the windward flank. This can further induce sustained and rapid uplift of rocks, exhumation and deformation, forming a large-scale antiform, which exhibits a certain degree of similarity to the eastern Himalayan syntaxis. We propose that the formation of the eastern Himalayan syntaxis share this similar mechanism. Our analysis of the results indicates that the influences of climatic forcing, tectonic forcing, and geothermal field on the evolution of orogenic wedge can be integrated into a single parameter (<span><math><msub><mi>E</mi><mi>F</mi></msub></math></span>), and we propose that 0.24≤<span><math><msub><mi>E</mi><mi>F</mi></msub></math></span>≤0.45 is a necessary condition for the development of a syntaxis, which provides a quantitative constraint on the formation of a syntaxis for the first time.</div></div>","PeriodicalId":11483,"journal":{"name":"Earth-Science Reviews","volume":"258 ","pages":"Article 104964"},"PeriodicalIF":10.8,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142552523","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}
