Marine sediment samples were collected along the Jeddah coast, Red Sea, Saudi Arabia, in order to assess radiation hazards and the exposure to human and marine living organisms. Using collaborative techniques, grain size, mineralogical characteristics, and natural radioactivity were investigated. To examine the influence of sediment characteristics over the distribution of the measured radionuclides, resulting data were statistically processed by using multivariate analyses. 238U, 232Th, and 40K levels were specified to be 19.50, 9.38, and 403.31 Bq kg−1, respectively. Radionuclides distributions were affected by sediment mud content, organic matter, and heavy minerals index. The calculated radiation risk parameters are within the safe range and lower than the global average. Natural radiation from these marine sediments is normal and poses no significant radiological risk to the public or marine living organisms. The natural radioactivity of the marine sediment in this Jeddah coastline will have to be monitored on a regular basis to avoid overexposure to the residents.

“…A number of studies have focused on trace metals (Al Farawati et al, 2011;Youssef, 2015;Brima and AlBishri, 2017;Al Mur et al, 2017;Ali et al, 2017;Fallatah et al, 2018;Al Mur 2020;Mannaa et al, 2021;Halawani et al, 2022;El Zokm et al, 2022) and/or organic pollutants (PAHs, polycyclic aromatic hydrocarbons) (El Maradny et al, 2023). Very few studies, also related mainly to metals and organic contaminants, are limited to local marine environments such as Al Lith (Abu-Zied and Hariri, 2016;Bantan et al, 2020), Yanbu (El Sorogy et al, 2023, and Jizan (Kahal et al, 2020). The sporadic and geographically confined nature of contaminant measurements acquired in the Red Sea highlight the importance of the dataset obtained in this work, since it extends along the whole Saudi Arabian coastline of the Red Sea.…”

Abstract. During the last decades, the coastal areas of the Kingdom of Saudi Arabia, on the Red Sea and the Arabian Gulf, have been subjected to intense economic and industrial growth. As a result, it may be expected that the overall environmental status of Saudi Arabian coastal marine waters has been affected by human activities. As a consequence, adequate management of the Saudi Arabian coastal zone requires an assessment of how the various pressures within this zone impact the quality of seawater and sediments. To this end, environmental surveys were conducted over 15 hotspot areas (areas subject to environmental pressures) in the Saudi Arabian coastal zone of the Red Sea and over three hotspot areas in the Saudi Arabian waters of the Arabian Gulf. The survey in the Red Sea, conducted in June/July 2021, acquired measurements from hotspot areas spanning most of the Saudi coastline, extending from near the Saudi–Jordanian border in the north to Al Shuqaiq and Jizan Economic City (close to the Saudi–Yemen border) in the south. The survey in the Arabian Gulf, carried out in September 2021, included the areas of Al Khobar, Dammam and Ras Al Khair. The main objective of both cruises was to record the physical and biogeochemical parameters along the coastal waters of the kingdom, tracing the dispersion of contaminants related to specific pressures. Taken together, these cruises constitute the first multidisciplinary and geographically comprehensive study of contaminants within the Saudi Arabian coastal waters and sediments. The measurements acquired revealed the influence of various anthropogenic pressures on the coastal marine environment of Saudi Arabia and also highlighted a strong influence of hydrographic conditions on the distribution of biochemical properties in the Red Sea and the Arabian Gulf. The data can be accessed at SEANOE https://doi.org/10.17882/96463 (Abualnaja et al., 2023), whereas the details of the sampling stations are available at https://mcep.kaust.edu.sa/cruise-postings (last access: 25 March 2024). The dataset includes the parameters shown in Tables 1a, b and 2a.

“…Precambrian volcanic, volcanoclastic, intrusive rocks, tertiary siliciclastic terrigenous rock series (sandstones and conglomerates), and gabbroic dikes are the major rock units present in these mountains. 16 The southwestern half of the area predominantly consists of Quaternary sediments, such as carbonate islands, sand deposits, coral reefs, pediments, alluvial deposits, sabkhas, dunes, and wadi flood plains. 17 Since ancient times, geothermal systems have piqued the interest of numerous scientists around the world.…”

The Al-Lith geothermal field in western Saudi Arabia is a characteristic medium-high enthalpy geothermal system, exhibiting features associated with tectonic activities linked to the Red Sea rifting. Ain Al-Harrah hot spring is located in the Al-Lith field, with discharge temperatures varying from 56 to 81 °C. The determination of water temperature and composition in a geothermal reservoir is critical to the design of utilization strategies, surface production facilities, and choice of materials. This research presents a comprehensive hydrochemical characterization of the Ain Al-Harrah hot spring and its relationship with the underlying geothermal system. This study was conducted in two main phases; first, the fieldwork involved the collection of water samples from the hot spring, measuring the temperature, pH, and electrical conductivity (EC) of the water. The second phase involved laboratory analyses of the collected samples, including major and trace element analyses, isotopic analysis, and geothermometry. The dominant hydrogeochemical processes in the region were determined by analyzing the hydrochemistry of the water samples. Thermal waters analyzed exhibited high concentrations of Na + (410−463 mg/L), HCO 3 − (64.48−90 mg/L), and Cl − (472.76− 581.95 mg/L), intermediate levels of K + (50.2−93.0 mg/L), and low levels of Mg 2+ (1.27−2.04 mg/L). The total dissolved solids (TDS) concentration ranges between 1830 and 2055 mg/L. The hot spring is categorized as Na-HCO 3 type facies that are moderately alkaline, with pH values ranging between 7.9 and 8.2. Analysis of trace element concentrations revealed that the hydrochemical processes were primarily governed by the abundance and solubility of trace elements in the rocks surrounding the hot spring, the pH, and the temperature of the hot spring water. The stable isotope data for δD (−12.36 to 15.21%) and δ 18 O (−2.84 to −3.38%) provided evidence that the thermal spring is of meteoric origin. Based on Na−K−Ca, K 2 /Mg, and quartz geothermometers, the temperature range of the reservoir was determined to be between 150 and 205 °C. The temperature range suggests a medium-to-high enthalpy geothermal system.
