Geochemical composition of dust from Qatar peninsula
(
Hamad bin Khalifa University Press (HBKU Press)
, 2015 , Conference Paper)
Atmospheric dust samples have been collected from different areas in Qatar and analyzed for major and trace element composition. This region of the Arabian Gulf represents an area largely affected by dust from natural and ...
Chlorophyll-a concentrations in the Arabian Gulf waters of arid region: A case study from the northern coast of Qatar
(
Elsevier
, 2022 , Article)
Remote sensing of spectrally active Chlorophyll-a (Chl-a) in the gulf water of an arid region is important to understand the spatial and temporal variations of phytoplankton and biomass in the water. This study characterizes ...
Population structure of marine turtles in coastal waters of Qatar
(
Inter-Research Science Publishing
, 2015 , Article)
Knowledge of the interrelationships between habitats and life-stage development in marine turtles requires an understanding of recruitment, size and age at maturity, sex ratios, growth and sexual development rates, ...
Mangrove-bearing limestone from the Eocene Dammam Formation, Arabian Gulf: Implications for the mangrove dispersal controversy
(
springer link
, 2012 , Article)
Fossil mangrove remains are found within the shallow carbonate strata of the Middle Eocene Dammam Formation of the Arabian Gulf. This formation is of wide distribution across most eastern parts of the Arabian Platform and ...
Methylmercury bioaccumulation among different food chain levels in the EEZ of Qatar (Arabian Gulf)
(
Elsevier
, 2020 , Article)
Methylmercury (MeHg) concentrations in three different species from different trophic levels with different amounts of Hg exposures were determined for the first time in the EEZ of Qatar. Sampling was conducted during ...
Characteristics and renewal of zooplankton communities under extreme environmental stresses in the oligotrophic hypersaline Arabian Gulf
(
Elsevier

Impacts of the exceptionally high temperature and salinity on species composition, abundance, biomass and diversity of zooplankton communities were examined in the central Arabian (Persian) Gulf in late winter and summer ...
Seasonal and body size-dependent variability in the bioaccumulation of PAHs and their alkyl homologues in pearl oysters in the central Arabian Gulf
(
Elsevier
, 2022 , Article)
Spatiotemporal concentration patterns for 19 parents and their alkyl homologues were measured in Pinctada radiata from 7 locations in the central Arabian Gulf around Qatar in the winter, spring and summer (2014–2015).
The ...
Phytoplankton-zooplankton relations in three inland seas along the Qatari coast (Arabian Gulf)
(
Taylor and Francis Ltd.
, 2005 , Article)
Phyloplankton and zooplankton community structures and abundance were studied in three inland seas around Qatar, two along the eastern coast and one along the northwestern coast. Despite some irregularities, the direct ...
Physical drivers of chlorophyll and nutrients variability in the Southern-Central Arabian Gulf
(
Academic Press
, 2023 , Article)
The southern-central Arabian Gulf demonstrates a poor understanding of nutrients and chlorophyll dynamics in physical-biogeochemical settings. Here, using data of chlorophyll, nutrients and hydrographic parameters collected ...
Seasonal variability of hydrography off the east coast of Qatar, central Arabian Gulf
(
Springer Nature
