Radioactivity levels in the marine environment along the Exclusive Economic Zone (EEZ) of Qatar
( Elsevier , 2015 , Article)A study on 137Cs, 40K, 226Ra, 228Ra, and 238U was carried out along the EEZ of Qatar. Results serve as the first ever baseline data. The level of 137Cs (mean value 1.6 ± 0.4 Bq m 3) in water filters was found to be in the ... -
Recognizing Panulirus meripurpuratus sp. nov. (Decapoda: Palinuridae) in Brazil—Systematic and biogeographic overview of Panulirus species in the Atlantic Ocean
( Magnolia Press , 2016 , Article)Genetic analysis divides Panulirus argus into two different species, physically separated by the Amazon-Orinoco plume since the Last Glacial Maximum. Panulirus argus sensu stricto is distributed north of this biogeographic ... -
Relationship Between Tree Size, Sediment Mud Content, Oxygen Levels, and Pneumatophore Abundance in the Mangrove Tree Species Avicennia Marina (Forssk.) Vierh
( MDPI , 2021 , Article)Mangroves are important in protecting and stabilizing coastal zones. Pneumatophores of the mangrove species Avicennia marina can form a large aboveground complex of aerial roots, which are important in supporting mangrove ... -
Reproductive effort of the European clam Ruditapes decussatus (Linnaeus, 1758): influence of different diets and temperatures
( Taylor & Francis , 2016 , Article)Ruditapes decussatus is a species of importance to aquaculture. For hatcheries to consistently produce spat it is essential to develop broodstock conditioning techniques. Food and temperature are the main factors that ... -
Short-term behavioural responses to thermal stress by hawksbill turtles in the Arabian region
( Elsevier , 2014 , Article)We present a previously unrecorded short-term behavioural response by hawksbill sea turtles to elevated sea surface temperatures in the Persian/Arabian Gulf. Surface waters typically exceed 30°C for sustained periods during ... -
Sources, spatial distribution and characteristics of marine litter along the west coast of Qatar
( Elsevier , 2020 , Article)The spatial distribution, sources and characteristics of marine litter (ML) from 36 locations spread over 12 beaches along the west coast of Qatar have been assessed. A total of 2376 ML items with varying sizes were found ... -
Spatial distribution, structural characterization and weathering of tarmats along the west coast of Qatar
( Elsevier , 2020 , Article)Oil pollution resulting from natural and anthropogenic activities in the Arabian Gulf as well as oil residue in the form of tarmat (TM) deposited on the coast is a major environmental concern. The spatial distribution, ... -
Spatio-temporal distribution and sources identifications of polycyclic aromatic hydrocarbons and their alkyl homolog in surface sediments in the central Arabian Gulf
