Consequently the Indian Oceanic Plate is converging towards the Malaysia–Indonesia–Thailand plate at the rate of 30 mm/year (Curray, 2005). Makkah (Mecca) early trade city in Arabia that became an Islamic religious center with the Ka'bah. Figure 3. (i) Monsoon which comes as South-West monsoon in Indian sub-continent proceeds into two branches after hitting the Southern tip ^ Bay of Bengal branch; Arabian sea branch; Monsoon occurs in alteration of dry and wet spells. What continent does the Arabian Sea border? The NO3− concentrations within the OMZ are about two times higher in the BOB in contrast to that of AS (Naqvi et al., 2006a). This rate is slightly lower than the GMSL rate over the same period. In Greek literature (which is where the phrase entered Western literature), the Seven Seas were the Aegean, Adriatic, Mediterranean, Black, Red, and Caspian seas, with the Persian Gulf thrown in as a "sea." 1 and 2). The Arabian Sea is a region of the northern Indian Ocean bounded on the north by Pakistan, Iran, and the Gulf of Oman, on the west by the Gulf of Aden, Guardafui Channel and the Arabian Peninsula, on the southeast by the Laccadive Sea, on the southwest by the Somali Sea, and on the east by India. Major seas contributing to Asian Drainage are Andaman Sea, Arabian Sea, Banda Sea, Barents Sea, Bering Sea, Black Sea, Caspian Sea, East Siberian Sea, Java Sea, Kara Sea, Laccadive Sea, Sea of Japan, Sea of Okhotsk. As denitrification proceeds, the residual nitrate in the oxygen-deficit subsurface waters becomes progressively enriched in 15NO3−. (Also Read – 10 Largest islands of World) On what continent is the Arabian Peninsula? The situation is being further aggravated in the Indus delta along Pakistan’s coast, in Sindh province. A uniquely resilient organism all but unheard of in the Arabian Sea 20 years ago has been proliferating and spreading at an alarming pace, forming thick, ... with socio-economic implications for large populations of the Indian sub-continent and the Middle East. Oxygen and carbon isotope records from various planktonic and benthic foraminifera in several cores located within and away from the axis of the Somali Jet along the Oman Margin indicate that sea surface temperatures were lower and varied randomly during interglacials, reflecting strong upwelling induced by a strong summer monsoon (Figure 3). takes place mostly in the upper ocean (within 10 m from the surface) whereas carbon uptake happens throughout the euphotic zone. The West Coast of India is thus encountering strong lateral stresses. Winter Monsoon. Naidu, in Encyclopedia of Ocean Sciences, 2001. TECTONIC FRAMEWORK OF THE WESTERN ARABIAN SEA The major tectonic and depositional features of the western Arabian Sea include the Indus Fan, the Owen Ridge, the Owen Basin, and the Arabian margin off Oman (see Figs. The Arabian Sea is a region, in the northwest part of Indian Ocean, at strikingly intense geopolitical and economic crossroads, notably, via marine trade route for oil and gas resources export. What two seas border Saudi Arabia? In BOB, upwelling is very weak and does not rise close to the surface. THE ARABIAN SEA covers approximately 1,491,000 square mi (3,862,000 square km) and is located between the Arabian and Indian peninsulas in the northwestern area of the INDIAN OCEAN, bounded by INDIA, PAKISTAN, IRAN, OMAN, YEMEN, and the HORN OF AFRICA. Several studies detected a recent trend of SL rise at the Maldives (Khan et al., 2002; Woodworth, 2005; Church et al., 2006; Palanisamy et al., 2014). All of these features reflect the long, complex tectonic history of the Northern Indian Ocean. The variability in seasonal contrast during glacials and during interglacials suggests that interannual and interdecadal changes in monsoonal strength were also greater during glacial periods than during interglacials (Figure 4). 7.3). Arabian Sea is only a part of the Indian Ocean that is located between the Arabian Peninsula and the Indian subcontinent. Large planktonic–benthic differences indicate a more vigorous monsoonal circulation during the summer monsoon. In April–May and September–November, Trichodesmium spp. Carbon isotope differences between planktonic and benthic foraminifera show lower gradients during interglacials, and higher gradients during glacials. The isotopic fractionation of nitrogen associated with denitrification enriches 15NO3− as 14NO3− is preferentially converted to gaseous products. This river system, among the largest deltas on Earth, is dominated by human activity since 19th century and is presently affected by (1) artificial flood levees, (2) barrages and their irrigation canals, (3) sediment impoundment behind upstream reservoirs, and (4) interbasin diversion (Syvitski et al., 2013). An important feature was highlighted by Clarke and Liu (1994) who pointed that the interannual SL signal along the Indian west coast, from the equator to Mumbai, is generated by zonal interannual winds blowing along the equator. This is happening at the half rate of 50–60 mm/year across the NW–SE trending Carlsberg Ridge in the Arabian Sea, and at the half rate of 18–24 mm/year across the N–S oriented Central Indian Ocean Ridge (Ramana, Ramprasad, Kamesh Raju, & Desa, 1993; Kamesh Raju, Ramprasad, Rao, Ramalingeswara Rao, & Varghese, 2003). India accounts for 23.6 percent of its annual haul mostly from waters 6 to 9 mi (10 to 15 km) from the coast. The Arabian Peninsula is located in Asia. Thus, glacial decreases in productivity and denitrification in the Arabian Sea are attributed to the weakening of the summer monsoonal winds that drive seasonal upwelling and dominate mean annual export production. Some of the countries that border the Arabian Sea are Pakistan, Oman, Iran, and India. 1.1). Arabian Sea Arabian Sea, northwestern part of the Indian Ocean, covering a total area of about 1,491,000 square miles (3,862,000 square km) and forming part of the principal sea route between Europe and India. They estimated significant RSL trends from PSMSL TGs having at least 40 years length. Arabian Sea, northwestern part of the Indian Ocean, covering a total area of about 1,491,000 square miles (3,862,000 square km) and forming part of the principal sea route between Europe and India. The lower gradients indicate that upwelling was strong (and pelagic productivity high) during interglacials due to a strong summer southwest monsoon. (2015) showed that, in the Indus delta over the past 100 years, as much as ∼0.5 mm year−1 of the SL trend can be linked to erosion and deposition of sediment since the last glacial–interglacial cycles. (2014) compared two longest TGs: Malé and Gan (∼20 years of length, available from PSMSL dataset), with satellite altimetry and past SL reconstruction. P.D. Close to the Arabian Sea coast, the peaks of the 1600-km-long chain of the Sahyadri Ranges rise to an elevation of 1646 m in northern sector, 1646 m in the central sector, and 2695 m in the southern sector. During the period of Roman Empire, its name was Erythraean Sea. Minke whales consume salty foods as they swim around The Arabian Peninsula is located in the continent of Asia and bounded by (clockwise) the Persian Gulf on the northeast, the Strait of Hormuz and the Gulf of Oman on the east, the Arabian Sea on the southeast, the Gulf of Aden, Guardafui Channel and Somali Sea on the south, the Bab-el-Mandeb Strait on the southwest and the Red Sea, which is located on the southwest and west. Global Position System (GPS) measurements in the international terrestrial reference frame show the direction in which the Indian continental plate is moving. The intervening dry spells of monsoon is called ‘Breaks’ in monsoon. (2010) pointed to a much weaker interannual variability, in terms of low frequency, of the Indian west coast compared with the east coast. The floor of the Arabian Sea is moving northwards and plunging into the Oman Trench just south of the Makran coast of Pakistan (Plate. Similar to OMZ, the denitrification process in the Arabian Sea also varied through time during glacial and interglacial periods. The N2 fixation rates in the eastern AS varied from ∼0.1–34 mmol Nm−2day−1. The current position of ARABIAN SEA is at North East Atlantic Ocean (coordinates 48.19488 N / 6.07645 W) reported 8 mins ago by AIS. 8. The organic carbon record from the Indian margin suggests lower productivity during glacial periods. The deepest known point in the Arabian Sea is at Wheatley Deep, where depths are more than 19,000 ft (5,800 m). Although slightly lower, these estimates are consistent with GMSL rates. (Modify from Banerjee,P. On the eastern side, the floor of the Bay of Bengal is sliding under the Andaman Island Arc–Indonesian Archipelago. Max. London, UK. Costal islands exist around the Arabian Sea and have proven significant for political and military purposes. During the oligotrophic inter-monsoon period, surface waters are depleted of combined nitrogen thus restricting the production of phytoplankton (Bhattathiri et al., 1996). Along the Oman Margin of the Arabian Sea, strong south-west summer monsoon winds induce upwelling. The Third and Final Continent by Jhumpa Lahiri I left India in 1964 with a certificate in commerce and the equivalent, in those days, of ten dollars to my name. Encyclopedia of Ocean Sciences (Second Edition), Reactive Nitrogen in Coastal and Marine Waters of India and Its Relationship With Marine Aquaculture, Deep Sea Research Part II: Topical Studies in Oceanography. Plate 1.4. (2013) showed that the Indian west coast intraseasonal SL variations are mostly remotely forced by the winds from equatorial region, and Suresh et al. Sea. Arabian Sea. About Arabia Arabia or the Arabian Peninsula is a peninsula in Southwest Asia, northeast of Africa between the Red Sea in the west and the Persian Gulf in the east. The denitrification in the Arabian Sea has been reported as being between 12 and 30 Tg years−1 and thus could account for up to 10–25% of total marine denitrification. The smallest of the groupings - the area - comprises two to five provinces. Mumbai and Karachi are two large global megacities (with more than 10 million inhabitants, Fig. Dhows (sailing vessels) full of spices and slaves have given way to petroleum tankers and container ships, yet the trade continues unabated. Advertisement. Asia is the largest continent on Earth. D. Prema, ... V. Kripa, in The Indian Nitrogen Assessment, 2017. The Gulf of Aden in the west connects the Arabian Sea to the Red Sea through the strait of Bab-el-Mandeb, and the G… Unnikrishnan and Shankar (2007) conducted complete reanalysis of these records. Similarly, the oxygen isotope difference between planktonic and benthic foraminifera along the Oman Margin reflects changes in thermocline depth, associated with summer monsoon-driven upwelling. West of the Konkan–Saurashtra Coast, the Laxmi Basin in the bottom of the Arabian Sea (Plate 1.4 inset) was created as a result of symmetric sea-floor spreading. The northern Arabian Sea is one of the few regions in the open ocean where thermocline water is severely depleted in oxygen. The sea is of geostrategic interest as it is the transit route for a major portion of the world's oil supply. Deep water reaches close to the bordering lands except in the northeast, off Pakistan and India. There are nine countries associated with the Arabian Peninsula: Saudi Arabia, Bahrain, Kuwait, Oman, Qatar, the United Arab Emirates, Jordan, Iraq, and Yemen. (Ganeshram et al., 2000). There are no islands in the middle of the Arabian Sea, where depths average in excess of 9,800 ft (3,000 m).
