Summary: This study evaluates the distribution, contamination, and environmental risk of potentially toxic elements (PTEs) in coastal sediments along the Arabian Gulf in Saudi Arabia. The results show severe enrichment of arsenic and mercury, while copper, lead, zinc, arsenic, and chromium concentrations do not pose a concern for benthic communities. However, nickel and mercury show a risk for benthic communities in certain areas. The sources of these elements include natural and anthropogenic factors, such as oil pollution, sewage, and industrial effluents near Al-Jubail industrial city.

Summary: The contamination and health risks of arsenic and chromium in the Al-Khobar coastal area have been assessed. The sediments showed low levels of contamination and the recorded values indicated acceptable or tolerable carcinogenic risks for both adults and children. However, children had higher cancer risks compared to adults.

Summary: A total of 886 Pinctada shells were collected from Al-Uqair beach along the Saudi Arabian Gulf coast, and their taphonomic signatures were studied. The results showed that these shells exhibited various trace fossils, with Entobia and Oichnus being the most common. The thin-shelled and smooth skeletons of the shells were preferable for the formation of these traces. In addition, the study revealed the presence of different encrusters and bioeroders on the internal surfaces of the shells, confirming the postmortem origin of the signatures. Disarticulation, fragmentation, and abrasion among the shells may be attributed to their mode of life as epifaunal byssate, filter-feeder bivalves in the shallow littoral and sublittoral zones of the continental shelf under strong currents conditions.

Summary: Geochemical analysis of sediment samples from a short core retrieved from a coastal creek in the Red Sea, Saudi Arabia, revealed three distinct units with different elemental enrichment characteristics. The lower and middle units show naturally driven enrichment, while the upper unit's enrichment is associated with road construction between the lagoons.

Summary: This study aimed to evaluate the sources and ecological risks of heavy metal contamination in soils of marine origin in central Saudi Arabia. Results showed that most of the soil samples had low risk, with only a small percentage categorized as moderate risk. Some heavy metals in the soil originated from natural processes, while others were attributed to anthropogenic processes, mainly from chemicals used in agriculture and phosphorus fertilizers.

Summary: This study examined bioeroded gastropod, bivalve, and coral specimens from the Jazan area along the Saudi Red Sea coast, identifying 22 ichnospecies of 8 ichnogenera. The traces were produced by various organisms such as sponges, drillers, bivalves, polychaete annelids, barnacles, and gastropods. The distribution and characteristics of these traces provide insights into the bioerosion processes in shallow, high energy marine environments.

Summary: The study investigated four Miocene outcrops of the Raghama Formation in NW Saudi Arabia for the first time, identifying facies types, facies associations, and sequence stratigraphy. The sections are controlled by fans flowing into the sea from higher altitudes, transitioning from alluvial fans and braided fluvial environments to lagoons and fringing reefs. The study revealed a well-preserved third-order depositional sequence, with variations in the A/S ratio related to factors such as sea level, climate, and tectonics.

Summary: The current study assessed the environmental risk of potentially toxic elements (PTEs) in the soils of Al-Ahsa, eastern Saudi Arabia, using various contamination indicators and multivariate methods. The results showed that the soil in Al-Ahsa is moderately polluted, primarily due to anthropogenic activities such as fertilizer and insecticide use. Furthermore, natural sources from earth crust materials also contribute to the levels of certain PTEs.

Summary: Thirty-four surface soil samples were collected from palm farms in the Al-Ammariah area of northwest Riyadh, Saudi Arabia to assess contamination and environmental risk of potentially toxic elements (PTEs). The samples were analyzed using ICP-AES and various pollution indices were employed to evaluate the contamination and environmental risks. The results showed indications of severe enrichment and significant contamination with mercury (Hg), and moderately severe enrichment with uranium (U) and arsenic (As). The PTEs originated from both natural and human sources.

Summary: This study aims to estimate the regional attenuation of coda waves in the southernmost part of the Arabian Shield. The analysis of the decay rate of coda wave envelope reveals a frequency-dependent attenuation relationship. The results indicate a low attenuation characteristic in the study area, possibly due to active rifting in the Red Sea combined with magma flow and migration.

Summary: The Upper Jurassic Jubaila Formation in central Saudi Arabia exhibits laterally coeval environments from the southwest to the northeast, showing characteristics of inner, mid-, and outer ramps. The distribution of microfacies in the Jubaila Formation is vertically arranged into four 3rd-order cycles, which correlate laterally overall the studied area, but are influenced by oscillations in eustatic sea-level during deposition.

Summary: A study identified various trace fossils in the Late Pleistocene coral reef along the Red Sea coast in northwest Saudi Arabia, mainly produced by sponges, bivalves, gastropods, polychaetes, and barnacles. The content of trace fossils suggested an Entobia ichnofacies formed in the coral reef during transgression, with habitat conditions changing gradually from shallow, high-energy back-reef to deep, low-energy reef slope.
