Investigation of long-term, basin-scale thermohaline trends in Qatar's marine region in response to environmental and climatic change
Husrevoglu, Y. Sinan; Al-Ansari, Ebrahim S. ( Hamad bin Khalifa University Press (HBKU Press) , 2016 , Conference Paper)The Arabian Gulf, an economically and geopolitically important marine area, is a semi-enclosed and shallow basin with an average depth 36 m. The Gulf is one of the seasonally warmest (i.e., in summer) and most saline marine ... -
Prospects for climate-scale regional numerical modelling for the Arabian Gulf and Qatar's marine region
Husrevoglu, Y. Sinan; Al-Ansari, Ebrahim S. ( Hamad bin Khalifa University Press (HBKU Press) , 2016 , Conference Paper)Physical oceanographic studies at the Environmental Science Center (ESC) entail observational and numerical aspects.
