Are offshore platforms a good candidate to restore functional diversity of reef fish communities in the Arabian Gulf?
( Elsevier B.V. , 2023 , Article)Human-made structures are ubiquitous in the marine realm. Complex structures such as oil and gas platforms may constitute a suitable habitat for species in areas where natural reefs have been highly degraded by coastal ... -
Assessing the vulnerability of socio-environmental systems to climate change along an altitude gradient in the Indian Himalayas
( Elsevier B.V. , 2019 , Article)Climate change is affecting biotic and abiotic components of the Himalayan ecosystem, disturbing existing socio-ecological systems. Future changes in the climate, coupled with ongoing development activities in the Himalayas, ... -
Burrowing crabs in arid mangrove forests on the southwestern Arabian Gulf: Ecological and biogeographical considerations
( Elsevier B.V. , 2020 , Article)Many species of mangrove crabs are essential in the formation of mangrove ecosystems, and the bioturbation resulting from the excavation of their underground chambers is directly correlated with substrate oxygenation and ... -
Characterization of the extracellular polymeric substances (EPS) of Virgibacillus strains capable of mediating the formation of high Mg-calcite and protodolomite
( Elsevier B.V. , 2019 , Article)The origin of dolomite –a common mineral in the geological record– is the subject of an ongoing debate. Among different hypotheses, it has been proposed that extracellular polymeric substances (EPS) excreted by microbes ... -
Characterizing fracture toughness using machine learning
( Elsevier B.V. , 2021 , Article)The existing models for fracture toughness characterization based on nanoindentations that account for the fracture length are limited to simple (ideal) geometries that are absent in shales. The present study proposes two ... -
Comprehensive pore size characterization of Midra shale
( Elsevier B.V. , 2021 , Article)Although the Middle East's carbonate reservoirs were the first and most studied rocks in the world, Middle Eastern shale reservoirs are still poorly understood compared with other unconventional formations in the US. We ... -
A comprehensive review of urban microplastic pollution sources, environment and human health impacts, and regulatory efforts
( Elsevier B.V. , 2024 , Article)Microplastic (MP) pollution in urban environments is a pervasive and complex problem with significant environmental and human health implications. Although studies have been conducted on MP pollution in urban environments, ... -
Ervilia castanea (Mollusca, Bivalvia) populations adversely affected at CO2 seeps in the North Atlantic
( Elsevier B.V. , 2021 , Article)Sites with naturally high CO2 conditions provide unique opportunities to forecast the vulnerability of coastal ecosystems to ocean acidification, by studying the biological responses and potential adaptations to this ... -
Hydroacoustics to examine fish association with shallow offshore habitats in the Arabian Gulf
( Elsevier B.V. , 2018 , Article)In order to implement spatial fisheries management in the Arabian Gulf, a better understanding of the distribution of fish in relation to benthic habitats is required. To facilitate this, hydroacoustic fish surveys were ... -
Increasing knowledge to restore oyster beds and related services in the Arabian-Persian Gulf
( Elsevier B.V. , 2023 , Article)The historical collapse of the pearl oyster ecosystem in the Arabian-Persian Gulf contributed to the long-term loss of biological and economic functionality within key shallow-water marine environments. This study introduces ... -
Microbially influenced formation of anhydrite at low temperature
( Elsevier B.V. , 2023 , Article)Calcium sulfate minerals are abundant in nature – on Earth and on Mars – and important in several fields of material sciences. With respect to gypsum and bassanite, anhydrite represents the anhydrous crystalline phase in ... -
Microplastics in different environmental compartments in India: Analytical methods, distribution, associated contaminants and research needs
( Elsevier B.V. , 2020 , Article)This study aims at reviewing the scientific literature related to microplastic (MP) pollution in various environmental matrices in India and highlighting the research gaps for future research priorities. Currently used ... -
Retrieval of suspended sediment concentration (SSC) in the Arabian Gulf water of arid region by Sentinel-2 data
( Elsevier B.V. , 2023 , Article)Suspended sediment concentration (SSC) in water increases temperature and turbidity, limits the photosynthesis of aquatic plants, and reduces biologically available oxygen. It is important to study SSC in the coastal waters ... -
Sentinel-2 image transformation methods for mapping oil spill – A case study with Wakashio oil spill in the Indian Ocean, off Mauritius
( Elsevier B.V. , 2021 , Article)Although several indices have been constructed and available at the Index database (IDB) for Sentinel-2 satellite to map and study several earth resources, no indices have been developed to map oil spill. We constructed ... -
Spatio-temporal distribution and sources identifications of polycyclic aromatic hydrocarbons and their alkyl homolog in surface sediments in the central Arabian Gulf
( Elsevier B.V. , 2019 , Article)The quantitative analysis of 18 parents and their alkyl homologs was performed in sediment samples from the central Arabian Gulf (Gulf) around Qatar Peninsula in six sequential seasons, winter 2014 to spring 2015, at 21 ... -
Targeted and suspect screening of contaminants in coastal water and sediment samples in Qatar
( Elsevier B.V. , 2021 , Article)In recent years, high resolution mass spectrometry (HRMS) combined with separation techniques has allowed comprehensive analysis of contaminants of emerging concern (CECs) as well as their metabolites and transformation ...
