( Springer Nature , 2023 , Conference Paper)The Lower Triassic Mahil Formation in North Oman is the outcrop time-equivalents to the hydrocarbon-bearing reservoir, Upper Khuff Formation (referred to as KS-1 cycle). The studied sections of the KS-1 cycle in the ... -
Distribution and environmental geochemical indices of mercury in tar contaminated beaches along the coast of Qatar
( Elsevier , 2022 , Article)The current study aimed to gauge total mercury (THg) concentration and the environmental geochemical indices in tarmat contaminated sediments and test their presence in targeted coastal species. Layers of hard asphalt-like ... -
Distribution, characterization and weathering of tarmats along the west coast of Qatar
( Qatar University Press , 2021 , Poster)Oil residue in the form of tarmat (TM) deposited on the coast of Arabian Gulf countries is a major environmental concern. In this study, the current TM pollution trend along the west coast of Qatar has been assessed and ... -
Distribution, pollution, and human health risks of persistent and potentially toxic elements in the sediments around Hainan Island, China
( Elsevier , 2022 , Article)Human activities have changed the global concentration of potentially toxic elements (PTEs) and significantly altered the marine ecosystem. Little is known about the concentrations of these PTEs around Hainan Island in ... -
Divergent changes of the elevational synchronicity in vegetation spring phenology in North China from 2001 to 2017 in connection with variations in chilling
( Royal Meteorological Society , 2021 , Article)Mountain ecosystems are sensitive to climate change, and vegetation phenology provides one of the best signals to exemplify ecosystem responses to climate change. Vegetation phenology of mountain ecosystems is usually ... -
Diversity and Zonation of Benthic Amphipod Crustaceans Affected by the Mississippi Submarine Canyon in the Northern Gulf of Mexico
( Frontiers Media S.A. , 2022 , Article)Amphipod crustacean diversity and zonation are described from the large Mississippi Canyon that extends from the continental shelf across the entire continental margin. Benthic amphipods were sampled on four cruises from ... -
Diversity of arbuscular mycorrhizal fungi and its chemical drivers across dryland habitats
( Springer , 2021 , Article)Qatar is largely characterized by a hyper-arid climate and low soil fertility which create a stressful soil environment for arbuscular mycorrhizal (AM) fungi. In a study of AM fungal communities and their relationship with ... -
Diversity of benthic macrofauna and physical parameters of sediments in natural mangroves and in afforested mangroves three decades after compensatory planting
( Springer , 2018 , Article)Mangroves in the Arabian Gulf are under pressure from land use change, leading to compensatory planting at sites without natural mangroves. In this study, we examine the potential long-term success of this form of ... -
Do changes in current flow as a result of arrays of tidal turbines have an effect on benthic communities?
( Public Library of Science , 2016 , Article)Arrays of tidal energy converters have the potential to provide clean renewable energy for future generations. Benthic communities may, however, be affected by changes in current speeds resulting from arrays of tidal ... -
Dolomite: Perspectives on a perplexing mineral
( research qate , 2009 , Other)Dolomite is a metastable mineral that can precipitate directly from solutions containing magnesium, calcium and carbonate to form cement or unlithified sediment. It can be categorized into two classes such as penecontemporaneous ... -
Editorial: Challenges in characterizing nano- to macro-plastics and adhered substances in the aquatic environment
( Frontiers Media , 2022 , Other)Globally, plastic contamination is one of the serious planetary threats, affecting almost all environmental matrices such as air, water, soil, sediment, and biota (including humans). It is estimated that ∼19 to 23 million ... -
Edms model verification considering remarkable changes in airport traffic system
( Hungarian Meteorological Service , 2016 , Conference Paper)This paper presents the verification process of the Emission and Dispersion Modeling System adapted to evaluate the air quality of Liszt Ferenc International Airport. One receptor point was selected at the Airport, at ... -
