The Persian Gulf is a shallow, semi-enclosed marginal sea where the Persian Gulf Water (PGW), one of the most saline water masses in the world, is formed due to the arid climate. The PGW flushes out of the Persian Gulf as a deep outflow and induces a surface inflow of the Indian Ocean Surface Water (IOSW), driving an inverse-estuarine type water exchange through the Strait of Hormuz. In this dissertation, the circulation and water mass transformation processes in the Persian Gulf and the water exchange with the Indian Ocean through the Strait of Hormuz, in response to the atmospheric forcing, are studied using the HYbrid Coordinate Ocean Model (HYCOM). The model is driven by surface wind stress, heat and fresh water fluxes derived from two sources: the COADS (Comprehensive Ocean-Atmosphere Data Set) monthly climatology and high frequency (2-hourly) MM5 (The Fifth-Generation NCAR/Penn State Mesoscale Model) output. This study is motivated by the time series measurements in the Strait during December 1996 to March 1998 by Johns et al. (2003), which also serve as a major benchmark for evaluating the model results. The simulations with climatological forcing show that the IOSW propagates in two branches into the Gulf, one along the Iranian coast toward the northern gulf and the other one onto the southern banks driven by the Ekman drift by the prevailing northwesterly winds. These two branches of inflow form two cyclonic gyres in the northern and in the southern gulf respectively. Cold, saline deep waters are formed both in the northern gulf and in the southern gulf during the wintertime cooling period and their exports contribute seasonally to the outflow in the strait. After formation in winter, the dense water in the shallow southwestern gulf spills off into the strait and causes high-salinity pulses in the outflow in the strait, a phenomenon also present in the observations. The export of dense waters from the northern gulf persists throughout the year, with the largest cold water export in summer. The intrusion of the IOSW in the model extends much farther into the Gulf in summer than in winter, which is in agreement with observations. By analyzing the salt balance in the basin and conducting sensitivity experiments, we show that it is the balance between the advection of IOSW and vertical upward flux induced by vertical mixing that mainly controls the seasonal variation of the surface salinity. The surface salinity in winter is increased by upward mixing from saltier subsurface waters, which is caused by the strong vertical mixing condition maintained by the surface heat loss. Surface wind stress, which opposes the inflow and is stronger in winter than in summer, plays a secondary role in modulating the seasonal intrusion of the IOSW. The MM5 high frequency forcing, capable of resolving synoptic weather events, leads to increased heat loss in winter, enhanced vertical mixing and higher annual mean evaporation rate. In the simulation with the high frequency forcing, the waters in the gulf are generally about 3 degree C colder and 1 psu fresher than with COADS forcing, and agree better with observations. The high-frequency forcing has little effect on the export of the dense waters from the northern gulf but delays the spillage of the waters from the southern gulf to April. A notable synoptic feature of the simulations is the annual appearance of eddies along the intruding salinity front. The typical sizes of the fully developed eddies in summer are about 100 km, about 3 times of the local Rossby deformation radius, consistent with a baroclinic instability process. The existence of these eddies is confirmed in satellite images of surface temperature in the Gulf.

This thesis is an attempt to provide a comprehensive overview of the British withdrawal from the Gulf in 1971, with special emphasis on the Trucial States before it became the United Arab Emirates in December 1971.The work commences with a review of the historical British connection with the Gulf from 1820 to the Kuwait operation of 1961. Then we look at various nationalist movements and the politicai upheaval around the Gulf, such as the Aden and Dhofar rebellions, and how that affected the British presence in the area. The British tried to curb such influence from reaching the Trucial States, especially those of Nasser and the Arab League, by introducing some economic development through the Trucial States Development Office. Furthermore, Britain gradually ceded various responsibilities such as legal and internal security to the rulers. At the same time the British companies working in the Emirates were encouraged to rely on their own resources without the protection of the British troops. The establishment of a federation between the nine emirates was Britain’s prime aim but when that failed in July 1971, the federation of the seven was established (Ras al-Khaimah entered the federation in February 1972). Furthermore, Britain worked hard to bring Saudi Arabia and Iran together in order to help to fill the vacuum that would occur after the withdrawal of the British troops. The latter policy changed Britain's stance on the territorial disputes from support for the rulers of the Trucial States to pressuring them to compromise with Iran over the Islands of Abu Musa and the Tunbs and with Saudi Arabia over Buraimi. The thesis concludes that all of these factors prepared the Emirates to stand on their own and consequently enabled the British withdrawal in December 1971.

When Bahrain's uprising began in February 2011, the opposition presented united front. By the time of the national dialogue a year later, however, it had fractured both along and within sectarian lines. The government’s inconsistent response to the uprising also demonstrated tensions within Bahrain’s royal family. An analysis of discourse on the national dialogue, terrorism and violence, expatriates, and the Gulf Union plan revealed that Bahrain's political factions were divided by their conceptions of Bahraini identity and citizenship. Bahrain was a young nation and questions of identity were still very much under debate. This work drew on newspaper opinion pieces, official statements published by political groups, and posters and videos they posted on social media to explain the questions of identity that developed around these political debates. I also examined how these debates continued to divide Sunni and Shi’i groups within the opposition as well as the moderate and conservative factions within the royal family. Finally, I considered how these groups used their varying conceptions of Bahraini citizenship to justify their tactics in pursuing or attempting to quash the uprising. Even as each group demanded rights for citizens, they disagreed on what citizenship meant. Similarly, denying that their opponents were “true citizens,” allowed each group to delegitimize views they disagreed with. / text
