The temperature data was bias-corrected with three and rainfall with six techniques. The 21-year (2000–2020) data was divided into two periods; i.e. 2000–2010 data was used for computing correction factors, and the remaining period data was used for validation by comparing with the ground station actual datasets. In temperature parameters, the CF_x (change factor daily basis) technique outperformed the SSBC_x (simple seasonal bias correction) and BC_x (bias correction daily basis) and showed excellent estimates similar to observed data. In the case of rainfall parameters, the CDF (cumulative distribution function) plots and KS (Kolmogorov–Smirnov) tests revealed no significant distribution differences across all locations before and after bias correction, except QMLC_x (quantile mapping linear correction) and QMPC_x (quantile mapping second-order polynomial correction) which added biases after bias correction. Amongst the six techniques evaluated for rainfall, the QM_x (basic quantile mapping) method reduces biases compared to raw rainfall data. We, therefore, recommend the direct usage of IMD raw gridded data for rainfall and bias-corrected data for temperature for climate change impact analysis for use in agricultural planning.</p></div>","PeriodicalId":476,"journal":{"name":"Arabian Journal of Geosciences","volume":"18 9","pages":""},"PeriodicalIF":1.827,"publicationDate":"2025-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145161492","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous knowledge of the lithofacies of older sediments in the onshore portion was largely inferred from geophysical exploration, while the sedimentology and depositional setting of the offshore section have not been documented in the literature. This study investigates the sedimentary facies and depositional environments of the sediments from the offshore Eastern Dahomey Basin, Nigeria, using core samples from well DN (depth: 2096–2150 m). Record of the vertical succession reveals lithologic characteristics such as channelized sandstone units, sand/heterolithic interbeds, varying sand/silt/mud heterolithic capturing alternations of bioturbated and non-bioturbated intervals, several <i>Glossifungites</i> demarcated discontinuity surfaces, and occasional fossiliferous sandstone. Many of the units/facies are recurrent, defined by sedimentary structures such as wavy, laser, lenticular, bidirectional beddings, cross bedding, consistent mud laminae and mud-rapes, coalified detritals, reactivation surfaces, and inclined heterolithic stratification. Six facies associations typical of ancient estuary-barrier mouth sediments were delineated, including fluvial channel, tidally influenced fluvial channel, intertidal flats, tidal sand bars, estuarine embayment, and shoreface. From the depth, 2150 to about 2114.5 m, the cores exhibit characteristics of a tide-dominated estuary bearing several transgressive surfaces of erosion; in contrast, 2114.5 to 2096 m corresponds to a regressive package of wave-dominated shoreface complex, characterized by initial predominance of suspension feeding structures at the lower shoreface and a generalized shallowing-upward succession. Trace fossil analysis reveals recurrent <i>Skolithos</i> and <i>Cruziana</i> assemblages, suggesting a brackish setting. The recurrence of <i>Glossifungites</i> ichnofacies helps identify surfaces of erosion/transgression and other stratigraphic surfaces which further strengthen an estuary setting for sediments. Abeokuta Group is a macrotidal estuary, and our findings suggest that Ise Formation represents a fluvial region, the Afowo Formation is a tide-dominated estuary, and Araromi Formation is the wave-dominated shoreface. This study provides new insights into the sedimentological evolution of the Abeokuta Group in the offshore Eastern Dahomey Basin.</p></div>","PeriodicalId":476,"journal":{"name":"Arabian Journal of Geosciences","volume":"18 8","pages":""},"PeriodicalIF":1.827,"publicationDate":"2025-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145160742","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Five distinct sand samples—Sumbal Sonewari sand soil, Kitchpora Wuyul 1 sand soil, Kitchpora Wuyul 2 sand soil, Preng sand soil, and Sumbal Sonmarg sand soil—were selected for examination. The primary objective is to elucidate fundamental characteristics crucial for understanding sand’s utility as a primary construction material in Kashmir. Experimental procedures, adhering to standard protocols, were conducted in the laboratory. Specific gravity measurement followed IS 2720-Part 3, water absorption testing adhered to IS: 3495, and sieve analysis complied with IS code 2386. Grain size distributions were evaluated through wet mechanical analysis, categorizing the samples as “poorly graded sand.” Additionally, mineralogical properties were scrutinized employing X-ray fluorescence and FE-SEM techniques to unveil the influence of mineralogy on physical attributes. Results indicate that Preng sand soil exhibited the highest specific gravity (2.62), while Kitchpora Wuyul 1 had the lowest (2.49). Water absorption tests revealed significant variation, with Sumbal Sonmarg (4.28%) and Kitchpora Wuyul 2 (4.09%) showing the highest rates, whereas Sumbal Sonewari (0.57%) and Preng (0.9%) exhibited the lowest. Gradation analysis classified all samples as poorly graded sand, requiring additional treatment for improved suitability in construction. These findings underscore the imperative need for reinforcement measures in utilizing such sand in construction endeavors to ensure structural integrity and durability. This research contributes valuable insights into optimizing the selection and application of sand resources in construction projects within the Kashmir region, enhancing sustainability and efficacy in infrastructure development.\u0000</p></div>","PeriodicalId":476,"journal":{"name":"Arabian Journal of Geosciences","volume":"18 8","pages":""},"PeriodicalIF":1.827,"publicationDate":"2025-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145170231","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study examines projected growth in water demand and supply over the next decade and its economic and environmental costs to inform policy development. Trends in water use were analyzed based on available data from 2010, with future projections extending to 2035 using the Water Evaluation and Planning (WEAP) model. The study revealed that the GCC’s water consumption averaged 463 cubic meters per capita annually, with 76% used in agriculture, 19% in domestic use, and 5% in industry. Variations in growth rates across countries indicate a need for balanced water management policies. Reducing water demand growth to 1–2%, combined with controlled desalination, groundwater extraction, and treated wastewater reuse, could mitigate future shortages. Virtual water trade and demand management measures are proposed to enhance efficiency.

This study uses field data sets, satellite-based observations, organic geochemistry, aeroradiometric data, and aeromagnetic data to look at intrasedimentary volcanic formations and detailed aeromagnetic and radiometric data in the Akiri region of the Central Benue Trough. We apply various enhancement methodologies to chart the structural and stratigraphic layout of the basement and enhance depth delineation, extending from 55.17 m to approximately 6735 m. Among these techniques for improving things are the first vertical derivative, analytic signal, source parameter imaging, Euler deconvolution, 2D power spectrum, center for exploration targeting (grid and porphyry), ratio maps, ternary maps, percentage potassium (%K), percentage thorium (eTh), and radiometric analyses. The results show six lithological units, several magmatic intrusions, and undulating and highly faulted basement surfaces with horst and graben structures. We determine shale to be the principal source rock for hydrocarbon maturation. The Central Benue Trough’s center region has a higher potential for hydrocarbon occurrence. However, further geophysical (seismic and well) studies are necessary to accurately locate and evaluate possible hydrocarbon reserves.

The temporal distribution of faunal records largely reflects both glacial-interglacial and millennial-scale changes in surface productivity in response to the monsoonal variations. The distinctive planktic foraminiferal assemblages reflect higher surface productivity resulting from intense southwest (SW) monsoon upwelling during interglacial MIS 1 and MIS 5 in both- coastal and open-ocean waters of the northwest Arabian Sea. Whereas the effect of the SW monsoon during MIS 3 was limited and contributed to the upwelling and surface productivity only in the coastal region. We also recorded the millennial-scale climate variability in the northwest Arabian Sea, which is closely linked with the extreme cold Younger Dryas (YD) event and several North Atlantic Heinrich (H) events. This explains the strong teleconnection between North Atlantic cold events and the reduced intensity of the southwest monsoon, resulting in a characteristic decline in surface productivity of the Arabian Sea. Furthermore, the spectral analysis of some faunal records allowed us to identify a Milankovitch and three sub-Milankovitch periodicities, which are both precession-driven and the harmonic progression of the precessional cycle, indicating that the high-resolution variabilities in surface productivity due to changing monsoonal strength are primarily governed by orbital forcing. The increased fragmentation of foraminiferal tests during interglacial intervals at deeper hole 722B (below OMZ) reflects increased carbonate dissolution, which could be caused by additional CO₂ release during the remineralization of a higher amount of organic matter.\u0000</p></div>","PeriodicalId":476,"journal":{"name":"Arabian Journal of Geosciences","volume":"18 8","pages":""},"PeriodicalIF":1.827,"publicationDate":"2025-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145163029","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
