Raman spectroscopy of the Dukhan sabkha: identification of geological and biogeological molecules in an extreme environment
(
The Royal Society
, 2010 , Article)
The characterization of minerals and biogeological deposits in a terrestrial Arabian sabkha has a direct relevance for the exploration of Mars since the discovery by the NASA rovers Spirit and Opportunity of evaporate ...
Lithology, mineral assemblages and microbial fingerprints of the evaporite-carbonate sediments of the coastal sabkha of Abu Dhabi and their extraterrestrial implications
(
cambridge university press
, 2010 , Article)
Deep-core and surface samples collected from the coastal sabkha of Abu Dhabi were subjected to a multi-proxy study, including petrographic, geochemical and spectroscopic analyses. The sediments studied are composed of ...
Microbial dolomites from carbonate-evaporite sediments of the coastal sabkha of Abu Dhabi and their exploration implications
(
wiley online library
, 2010 , Article)
Detailed petrographic studies of Recent dolomites from the coastal sabkha of Abu Dhabi using SEM and Energy Dispersive X-ray (EDX) analyses indicate that most of the dolomite started to form in " micro-niches" (i.e. small ...
Seismic detection of a sinkhole using spectral-based analysis
(
Society of Exploration Geophysicists
, 2014 , Conference Paper)
Seismic data recorded during a survey in the vicinity of a sinkhole revealed distinct resonances at 70 Hz. Frequency domain data inversion based on exact modeling produced effective elastic parameters for the location over ...

(
Elsevier B.V.
, 2017 , Conference Paper)
Pedestrian signal control is a main influencing factor on the Level of Service of crossing facilities and on the safety performance considering conflicts with vehicles. In signal design, pedestrian clearance time is a key ...
Flow mapping of multiphase flows using a novel single stem endoscopic particle image velocimetry instrument
(
Institute of Physics Publishing
, 2011 , Conference Paper)
Particle image velocimetry (PIV) is a successful flow mapping technique which can optically quantify large portions of a flow regime. This enables the method to be completely non-intrusive. The ability to be non-intrusive ...

(
Elsevier Ltd
, 2017 , Article)
In this study, Aluminum matrix composite reinforced with 5, 10 and 15 vol% Al2O3 particles were fabricated using microwave assisted rapid sintering technique followed by hot extrusion. The effect of concentration of Al2O3 ...
Phytoplankton along the coastal shelf of an oligotrophic hypersaline environment in a semi-enclosed marginal sea: Qatar (Arabian Gulf)
(
Elsevier
, 2013 , Article)
Phytoplankton biomass (chlorophyll a concentration), primary production, abundance, species diversity and species groupings were measured in the coastal waters surrounding Qatar (Arabian Gulf) at 13 stations in February ...
Sources of primary production supporting food webs in an arid coastal embayment
(
Springer Nature
, 2012 , Article)
Penaeid shrimp can be useful ecological indicators of linkages between shallow tropical coastal habitats, acting as integrators of carbon and nitrogen sources due to their generalist feeding habits and their mobility between ...
