![]() ![]() Because of being generally warm (T > 21˚C), and subject to dry winds much of the year, the Gulf is a site of high evaporation rates, estimated at 0.5-1.0 cm/day. Nonetheless, inter-annual variability in wintertime temperatures appears to set the depth of maximum mixing. Much of the seasonal stratification variability is determined by exchanges with the rest of the Red Sea. The Gulf exhibits a seasonal cycle of stratification in spring, maintenance of a shallow thermocline in summer, and subsequent deepening of the thermocline to produce deep mixed layers in winter. The Gulf is connected to the Red Sea by the Strait of Tiran, which has a sill depth of about 265 m. The bathymetry of the Gulf is arranged in three deep elongated basins separated from each other by relatively low sills. The deepest point in the Gulf reaches 1825 m with an average depth of 800 m. It is a semi-enclosed basin that extends over a length of 180 km with a width between 5 and 25 km with an average of 16 km ( Figure 1). The Gulf of Aqaba is located in the sub-tropical arid zone between 28˚-29˚30N and 34˚30-35˚E. The water of the Gulf of Aqaba is the warmest among the world’s seas due to the climate of the region. The Gulf of Aqaba is the north-eastern extension of the Red Sea. Slightly high values of total hydrocarbon wereĭetected, which can be solved by regular cleaning. In conclusions, the environmentalĬondition of the RYC’s marina is acceptable in term of the residence time andĮxchange system with open water. Gate with open water was 5.33 ± 2.63 cm/s, which is relatively comparable withĬurrent speed in vicinity of study area. The mean value of current speed at the RYC’s marina This flushing time is acceptableĪvoid stagnant seawater. Time of waters inside the marina was 1.32 days. Therefore, the major factors that influence theĭistribution of total hydrocarbon within the marina are the current system andīoats’ movements as well as the location reference to the gate. There was no correlation betweenĭistribution of total hydrocarbon and temperature (R 2 = 0.048 p = 0.49) in the marina. Hydrocarbon were found at the corners of the marina and at areas with The measurements range of total hydrocarbon in the Which are all comparable with open waters. ![]() Results of physical parameters revealed no significant differences among sites, The mean values of temperature, salinityĪnd density at surface and bottom waters in the RYC’s marina were 27.13☌ ±Ġ.03☌, 40.51 ± 0.02 psu and 26.83 ± 0.02 kg The water exchange and residence time were calculated using data of current speedĪnd direction at 16 sites (C1 - C16). Total hydrocarbon was measured at surface at 12 sites (HC1-HC12). (temperature, salinity and density) were measured at surface and bottom waterĪt 19 sites (T1 - T19). (RYC), which is located in the Jordanian Gulf of Aqaba. This research was aimed at studying the generalĮnvironmental status of the marina at Royal Yacht Club ![]()
