INSIGHTS INTO THE NATURAL DEGRADATION RATE OF PLASTICS IN THE SEAWATER ENVIRONMENT AND THEIR DEGRADATION BY-PRODUCTS (PHTHALATES AND BISPHENOL A)
(Environmental Sciences, 2023 , Master Thesis)
Most plastics end up in the oceans. Their chemical additives that leach out into the ocean can be detrimental to humans and animals. This study investigates the degradation-fragmentation of different plastic types for 140 ...
INVESTIGATION OF TEMPORAL VARIABILITY OF CORALS REVEALED BY ROV VIDEOS AT OIL PLATFORMS IN THE ARABIAN GULF
(Environmental Sciences, 2023 , Master Thesis)
The study was conducted at AL-Shaheen oil field within the Arabian Gulf using remotely operated vehicle (ROV) footages in different oil platforms to investigate the impact of platform depth, age, and weight on coral relative ...
Phylogenetic Diversity of Cyanobacteria from Qatar Coastal Waters
(Biological and Environmental Sciences, 2014 , Master Thesis)
Cyanobacteria represent the major microorganism phyla, being diverse and widespread group inhabiting most of the earth's environments. The recent increase of occurrence of toxic cyanobacterial strains in the marine environment ...
Spatial and Temporal Distribution of Heavy Metals in Marine Sediment Along the Doha Bay
(Biological and Environmental Sciences, 2013 , Master Thesis)
Concentrations of twenty five heavy metals (Ag, Al, As, Ba, Be, Ca, Cd, Co, Cr, Cu, Fe, K, Li, Mg, Mn, Mo, Na, Ni, Pb, Sb, Se, Sr, V, Zn, and Hg) in surface sediment from ten transects each with five stations were studied. ...
Characterization of Microalgae Species from Qatar Coastal Waters for Animal Feed Production
(Biological and Environmental Sciences, 2014 , Master Thesis)
Food security worldwide is field of major research and investigation to improve and find new resource production systems for a continuously growing world population. The state of Qatar being an arid and with limited arable ...
Seasonal Changes in Biodiversity and Abundance of Invertebrates in Different Ecological Environments
(Biological and Environmental Sciences, 2013 , Master Thesis)
Biodiversity is a natural quality that must be measured to be understood. It is the measurement of the quantity and diversity of the biota in an area. Each area of the world has its own unique biodiversity as defined by ...
An Integrated Approach to Benthic Habitat Classification of the North Eastern Qatar Marine Zone Using Remote Sensing, Geographic Information System, and in Situ Measurements
(Biological and Environmental Sciences, 2014 , Master Thesis)
A key aspect in the conservation management of the coastal marine zone is mapping the benthic habitat, which is the focus of the work presented in this project. Multispectral Worldview-2 (WV2) satellite data acquired in ...
Disinfection By-Products of Chlorine Dioxide (Chlorite, Chlorate, and Trihalomethanes): Occurence in Drinking Water in Qatar
(Biological and Environmental Sciences, 2014 , Master Thesis)
The occurrence of disinfection by-products (DBPs) of chlorine dioxide (ClO₂) in drinking water, namely: chlorite, chlorate, and THMs as well as the concentration of ClO₂ were investigated. Two hundred ninety four drinking ...
Distinctive Physiology (Growth and Photosynthetic Efficiency) of Qatari Corals Under Variable Dynamic Factors, An Experimental Approach
(Biological and Environmental Sciences, 2014 , Master Thesis)
The Arabian Gulf is well known as being probably the most extreme environment in which zooxanthellate coral reef communities occur. A combination of both extremely high and low temperatures as well as high salinities, ...
Measurement and Modeling of NO2 Traffic-Related Air Pollution in Doha, Qatar
(Biological and Environmental Sciences, 2013 , Master Thesis)
Six major intersections along C-ring road of Qatar were investigated for NO2 emission. NO2 is considered to be a marker of vehicular pollution thus in this study, its relationship was established with traffic volume in ...
