Large-scale mountain modifies the atmospheric circulation directly through dynamic and thermodynamic process, and also indirectly through the interaction with the ocean. To investigate orographic impacts on tropical climate, a fully coupled general circulation model (CGCM) is de…

This study describes the ocean circulation of the Indonesian Seas based on results using a 3D regional model. The model has four open ports to simulate inflow of North Pacific Water from the Mindanao Current, inflow of South Pacific Water from the New Guinea Coastal Current, out…
The tectonic opening and closing of ocean gateways played a key role in global climate change during the Cenozoic. Although changes in these gateways affected ocean circulation and heat transport, many of their paleoceanographic effects are still unknown. This dissertation exami…
Climate variability has large impacts on humans and their agricultural systems. Farmers are at the center of this agricultural network, but it is often agricultural planners—regional planners, extension agents, commodity groups and cooperatives—that translate climate information…
Monthly mean sea levels in the Arabian Sea have been investigated for seasonal-to-annual variation and interannual oscillations. Relative Sea level in the Port of Aden is rising either due to the widening sea floor and/or to volume changes caused by thermal expansion. However, a…
The phytoplankton abundance indicated by chlorophyll concentrations is a key indicator of the Kuwait's aquatic environmental sustainability, the primary productive environment of Kuwait. Unfortunately, there is little information about the spatial and temporal phytoplankton vari…
Attempts to use stable isotope carbon (δ13C) and nitrogen (δ15N) ratios to construct trophic positions and track mercury biomagnification in zooplankton and 13 fish species from a coastal food web of the Gulf of Oman illustrated some potential differences in this environment com…
Organic and inorganic geochemical proxies from two cores in the northeastern (NE) and western Arabian Sea were employed to study orbital and suborbital climate variability of the Indian Ocean monsoons. In the NE Arabian Sea 230Th-nonnalized 232Th fluxes and authigenic uranium co…
Indonesia is a center of marine biodiversity and its coral reef ecosystems are some of the most threatened worldwide. To help address questions related to the ecology and conservation of these important reefs, I applied a population genetic approach to understand the connectivit…
The Indian Ocean is one of the three principal ocean basins in the world, yet it is the least explored. It is unique in that it is not connected directly to the Arctic and is forced by seasonally reversing monsoons, which play a very important role in its variability. Previous s…
The northern Red Sea and the Dead Sea rift represent the incipient stage of accreting plate boundary, occurring partly at sea and partly on land. The evolution of the Red Sea as a deviatoric boundary between the Arabian and the Nubian plates started in the Late Oligocene-Early M…
An idealized box model of the Indian Ocean is used to examine the hypothesis proposed by Godfrey and Weaver (1991) that the buoyancy-forced Leeuwin Current off the west coast of Australia is a manifestation of a basinwide thermohaline circulation driven by the Indonesian through…
The data from INSAT-IB geosynchronus satellite has been used to make maps of albedo, solar energy and temperature distribution over the Arabian Sea which includes the Pakistan's fifth province in the ocean. Visible data in the range of 0.55 to 0.75 μm and infrared data in the ra…
Current meter data in the mid-Lombok Strait region in 1985 show that 42% of the variance in the currents is within the intraseasonal frequency band (10-100 day-1). It is about two times the variance of the tidal currents. This intraseasonal variability appeared as episodic north…
Sixty eight species of decapod Crustacea were collected in the coastal waters of Dubai, United Arab Emirates. These consisted of one species of peneid shrimp, fourteen species in four families of caridean shrimp, one scylarid lobster, six species of hermit crabs, ten species of …
The distribution patterns of infaunal polychaetes can be influenced by several factors (e.g., predation, competition, and, or disturbance). Adult-larval interactions have been shown to be important in communities where adult densities are high. Manipulative field experiments wer…
The goal of this research has been to determine the nature and origin of low-latitude terrestrial climate variability prior to and after the rapid expansion of high-latitude ice sheets near 2.4 Myr to understand the interactions between high- and low-latitude climate systems sin…
A real time numerical model is developed to simulate tidal flow in the interconnected Musi-Upang estuaries, South Sumatra, Indonesia. The model adopted the existing code for solving two dimensional shallow water wave equations. The code utilized an explicit finite difference sch…
