Benthic surveys of the historic pearl oyster beds of Qatar reveal a dramatic ecological change
(
Elsevier
, 2016 , Article)
The study aimed to confirm the presence of historic oyster banks of Qatar and code the biotopes present. The research also collated historical records and scientific publications to create a timeline of fishery activity. ...
Associated effects of storage and mechanical pre-treatments of microalgae biomass on biomethane yields in anaerobic digestion
(
Elsevier
, 2016 , Article)
The pre-treatment of microalgae cell walls is known to be a key factor to enhance methane (CH4) yields during anaerobic digestion. This study investigated the combined effects of two different biomass storage methods and ...
Mercury accumulation in Lethrinus nebulosus from the marine waters of the Qatar EEZ
(
Elsevier
, 2017 , Article)
Total mercury (THg) and methylmercury (MeHg) were recorded in the commercial demersal fish Lethrinus
nebulosus, caught from six locations in Qatar EEZ (Exclusive Economic Zone). Concentrations of THg decreased
in the ...
Prevalence of microplastics in the marine environment of Qatar's exclusive economic zone
(
Bloomsbury Qatar Foundation Journals
, 2015 , Conference Paper)
Microplastics are now firmly recognized as a ubiquitous and growing global threat to marine biota, as well as their associated ecology and habitats. The prevalence of microplastics in the marine waters within Qatar’s ...
Characteristics and sources of anthropogenic and biogenic hydrocarbons in sediments from the coast of Qatar.
(
Elsevier
, 2017 , Article)
Surface sediment samples from the coastal zone of Qatar were collected and analyzed to determine the characteristics, and sources of anthropogenic and biogenic hydrocarbons. The main compounds in these surface sediments ...
Trace element composition of size-fractionated suspended particulate matter samples from the Qatari Exclusive Economic Zone of the Arabian Gulf: the role of atmospheric dust
(
Copernicus Publications

The arid subtropical ecosystem of the central Arabian Gulf was used to explore the combined effects of low primary productivity, high salinities, and variable temperatures on the composition and structure of benthic ...
The benthic sea-silk-thread displacement of a sessile bivalve, Pinctada imbricata radiata (Leach, 1819) in the Arabian-Persian Gulf
(
Public Library of Science
, 2019 , Article)
A number of molluscs within the Class Bivalvia are defined by their ability to secrete fine silk like threads known as byssus which are used to anchor themselves to solid substrates. With relatively few exceptions the ...
The biological effects of chemical contaminants in the Arabian/Persian Gulf: A review
(
Elsevier
, 2020 , Article)
© 2019 Elsevier B.V. The Arabian Gulf is a shallow sea naturally exposed to extreme conditions of temperature and salinity due to its location, semi-enclosed nature, bathymetry and restricted circulation. Compared to open ...
