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. 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). 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. Global Position System (GPS) measurements in the international terrestrial reference frame show the direction in which the Indian continental plate is moving. Along the Oman Margin of the Arabian Sea, strong south-west summer monsoon winds induce upwelling. About Arabian Sea: The Facts: Area: 1,491,000 sq mi (3,862,000 sq km). The variability in seasonal contrast during glacials and interglacials suggests that interannual and interdecadal changes in monsoonal strength were also greater during glacial periods than during interglacials (Figure 4). Aparna et al. It lies southwest of Sri Lanka and India, about 1,000 kilometres from the Asian continent. The DIN from rivers exported to the BOB is less (<0.5 Tg N a−1) compared to AS (Naqvi et al., 2010). Interseismic geodetic motion and far-field coseismic surface displacements caused by the 26 December 2004 Sumatra earthquake observed from GPS data. 4. coastline : Asia h s 'a ela ively smooth coastline with few in entat o s. Along the east coast is the China Sea, the Yellow Sea and the Sea of Japan. During the period of Roman Empire, its name was Erythraean Sea. The Maldives, located from 7°N to 0.5°S in the northeastern Arabian Sea, consists of 1190 small islands with 80% of the land area to be less than 1 m above SL (Khan et al., 2002). Naidu, in Encyclopedia of Quaternary Science, 2007. 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. Similar to OMZ, the denitrification process in the Arabian Sea also varied through time during glacial and interglacial periods. All of these features reflect the long, complex tectonic history of the Northern Indian Ocean. (a radiolarian) and pollen reveal that the south-west monsoon winds were more intense during interglacials (warm periods) and weaker during glacials (cold periods), recognized by the oxygen isotopic stratigraphy in the same samples. Iran. Fig. (2013) showed that the Indian west coast intraseasonal SL variations are mostly remotely forced by the winds from equatorial region, and Suresh et al. 9) (Ganeshram et al., 2000). Winter Monsoon. The north western part of India grows colder than Arabian Sea and Bay of Bengal and the flow of the monsoon is reversed. 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.

The δ15N and organic-carbon profiles indicate higher productivity and denitrification during the Holocene as compared to the last glacial period. The hypoxia along the Western Indian continental shelf might have increased by augmented nitrogen input from runoff and atmospheric deposition through anthropogenic activities (Naqvi et al., 2009). We updated the RSL trends at Cochin to be 0.7 mm year−1 and at Mumbai to be 1.5 mm year−1 (Table 7.8), and ∼1.8–2.5 mm year−1 from the SL reconstruction (Fig. 1.1). Lying more than 2100 m deep under the Arabian Sea, the sediment-covered Laxmi Basin, with its seamounts and guyots adjoining the NW–SE trending Laxmi Ridge, is characterized by a pattern of gravity and magnetic anomalies resulting from the intrusion of magmatic material in an essentially oceanic crust and thus pointing to seafloor spreading (Chaubey, Bhattacharya, Murty, & Desa, 1993; Bhattacharya et al., 1994). (2014) focused on the long-term SL rise in the northwestern Persian Gulf. Arabian Sea. On average, over the same period, Asian megacities faced an annual population growth rate of 3.7% against a rate of 2.6% in the rest of the world (Singh, 2014). We find the major harbors of Kochi and Mumbai on the southwest coast of India, and further in the northwest, the largest and most frequented ports serving the Arabian Sea, and, in the northeast, the major port of Karachi in Pakistan. Detailed analyses of various monsoon tracers such as abundance of G. bulloides and Actinomma spp. Fishing stocks are being depleted because of a combination of overfishing and pollution along the Indian coast. The Arabian Sea is a body of water that is very important as a shipping lane. Compared with the Arabian Sea, circulation in the Bay of Bengal is weaker and less predictable, and its response to monsoon reversal more complex, because it is partially open on its eastern margin where there is connection with the western Pacific through the Indonesian archipelago. Primary branches of the Arabian Sea are the Gulf of Oman, which joins it to the Persian Gulf via the Strait of Hormuz and the Gulf of Aden, which joins it with the Red Sea via the BAB EL MANDEB. It is surrounded by water bodies on all sides. A larger oxygen isotope difference between planktonic and benthic foraminifera during interglacials reflects the presence of a shallow thermocline, as a result of the strong summer monsoons. 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. The deepest known point in the Arabian Sea is at Wheatley Deep, where depths are more than 19,000 ft (5,800 m). They explained this by the changes in salinity in coastal waters, due to the seasonal fluctuations in river runoff, related to the strength of the monsoon and to the dynamics of ocean currents along the Indian coast. These skates were used thousands of years ago in present-day Finland on which continent? 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. (Modify from Banerjee,P. On the west coast of India, they selected three TGs from the PSMSL data set at Mumbai (also known as Bombay), Mangalore, and Kochi (or Cochin) with a time length sufficient to detect significant changes. Thermal stratification is strongest in April and May because of the northern excursion of the sun and cloudless skies, though because salinity distribution largely determines mixed-layer depth, the pycnocline remains rather shallow and abrupt. The overexploitation of fish stocks is mostly due to large fishing vessels operating illegally near the coast. (2010) pointed to a much weaker interannual variability, in terms of low frequency, of the Indian west coast compared with the east coast. Periods with a pronounced OMZ (such as the present times) are characterized by shallow winter mixing, while annual surface-water productivity is high. Shankar and Shetye (1999) demonstrated that the interdecadal SL variations recorded by the Mumbai TG closely follow the monsoon rainfall over the Indian subcontinent. Table 7.8. ... a continent south of Europe and between the Atlantic and Indian oceans. Arabian Plate One of the present-day minor lithospheric plates, separated from the African Plate by the spreading Red Sea, the continuation of the Carlsberg Ridge into the Gulf of Aden, and the Dead Sea transform system, while the boundary with the Indo-Australian Plate is the Owen Fracture Zone; the plate is colliding with the Iran Plate. Circulation and mixed-layer depth in the north of the Bay of Bengal is determined by winter cooling and by the very large fluvial input of freshwater from the mouths of the Ganges and Irrawaddy rivers, as well as by the reversing monsoon winds and the influence of the zonal currents lying across the south of the embayment. The northern Arabian Sea is one of the few regions in the open ocean where thermocline water is severely depleted in oxygen. Figure 3. N. Niitsuma, P.D. 7.4) and from altimetry (5–7 mm year−1, Fig. Two TG records with 30-year length are available from the RLR PSMSL data set in the capital of Mauritius Port Louis, where we found an RSL rate of ∼4 mm year−1, and the Rodrigues Island with an RSL trend of ∼6 mm year−1 (Table 7.8). In the north-east is the Sea of Okhotsk and the Bering Sea. 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. True or false: The easternmost point of the Asian continent is 55 miles (89 kilometers) from the westernmost point of the continent of North America. The Arabian Sea, however, is more exciting and diverse off the Bombay – Cochin coastline. Whales can only taste salty foods. 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. We provide “Turnkey” solutions for clients requirements for all above destinations and also undertake cargo on inducement basis. blooms occur in the eastern and central AS when bioavailable nitrogen is relatively scarce at the surface due to denitrification. The average rate of sedimentation was higher during glacials than during interglacials, because the enhanced precipitation over the Arabian Peninsula during glacials caused enhanced transport of terrigenous material by rivers into the Arabian Sea. As denitrification proceeds, the residual nitrate in the oxygen-deficit subsurface waters becomes progressively enriched in 15NO3−. It is bounded to the west by the Horn of Africa and the Arabian Peninsula, to the north by Iran and... Encyclopedia / Oceans & Seas Deep water reaches close to the bordering lands except in the northeast, off Pakistan and India. 1 and 2). Asia is the largest continent on Earth. These high rates are confirmed by the ASL trends from the SL reconstruction (3–4 mm year−1, Fig. What is the difference between Indian Ocean And Arabian Sea? Therefore, the δ15N record and associated data indicate that the Arabian Sea has exhibited large, climate-driven variations in denitrification, probably forced directly by changes in the intensity of the summer monsoon and associated upwelling (Altabet et al., 2002). There are nine countries associated with the Arabian Peninsula: Saudi Arabia, Bahrain, Kuwait, Oman, Qatar, the United Arab Emirates, Jordan, Iraq, and Yemen. Such studies show that the seasonality was stronger during glacials and weaker during interglacials, because during glacials the south-west summer monsoon was weaker and the north-east winter monsoon stronger. Minke whales consume salty foods as they swim around 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.Its total area is 3,862,000 km 2 (1,491,000 sq mi) and its maximum depth is 4,652 meters (15,262 ft). On the eastern side, the floor of the Bay of Bengal is sliding under the Andaman Island Arc–Indonesian Archipelago. D. Prema, ... V. Kripa, in The Indian Nitrogen Assessment, 2017. These atoll islands are morphologically sensitive to floods, tsunamis, and SL changes (Kench et al., 2006). The southern and southeastern boundaries of the Arabi… The northern area has very low surface salinities year-round, so that the 33.5%o isohaline lies zonally, and almost permanently, at the sea surface across the Bay of Bengal at 10–15°N. An ocean bounded by North America and South America in the Western Hemisphere and by Europe and Africa in the Eastern Hemisphere. Alan R. Longhurst, in Ecological Geography of the Sea (Second Edition), 2007. (Ganeshram et al., 2000). Gandhi et al. 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). This population increase and industrial development create major pollution problems. This phenomenon has also been reconstructed for the Oman margin, based on a glacial-age decline in biobarium and organic carbon accumulation recorded in regional sediments. (2012) demonstrated that the dominant climatic signals, IOD and ENSO, do not display any coherent response along the eastern Arabian Sea, in contrast to the BoB. The Indian Ocean is the third largest ocean; it separates India from Africa. The Arabian Desert is bounded by the landmass of the Syrian Desert only on the northern side, whereas it is bounded by the sea on all of its other sides. 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. This phenomenon has also been reconstructed for the Oman margin, based on a glacial age decline in biobarium and organic-carbon accumulation recorded in regional sediments. The Arabian Peninsula is located in Asia. The N2 fixation rates in the eastern AS varied from ∼0.1–34 mmol Nm−2day−1. Rising high against the 40–120 m of undulating terrain of the coast of emergence, the 900- to 2695-m high Sahyadri is remarkable for its spectacular western flank that is characterized by high escarpments alternating with narrow, irregularly tilted terraces forming a ‘landing stair’ (ghat) geomorphic architecture known as the Western Ghat. (B) Carbon isotope profiles of planktonic foraminifera (δ13CP) and benthic foraminifera (δ13CB) and the difference between planktonic and benthic records (Δδ13CB−P) over last 800 000 years at ODP Site 723 in the Arabian Sea. 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. (a) Oxygen isotope profiles of planktonic foraminifera (Pulleniatina obliquiloculata, δ18OP) and benthic foraminifera (Uvigerina excellens, δ18OB), and the difference between oxygen isotopes of planktonic and benthic foraminifera (Δδ18OB–P). The other months of the year, winds are typically from the northwest off the dry continent. The Indian Ocean is the warmest of all the ocean and also the youngest of all oceans. Although slightly lower, these estimates are consistent with GMSL rates. The peninsula is separated from Africa by the Red Sea. The Arabian Sea is an important link among the neighboring countries like Iran, UAE, Yemen, Oman, Pakistan, India, and the Horn of Africa nations. The NO3− concentrations within the OMZ are about two times higher in the BOB in contrast to that of AS (Naqvi et al., 2006a). Benthic Foraminifera δ18O, δ15N and organic-carbon content from a sediment core along western continental margin of India (MD76-131). Figure 4. The principal waterway draining directly into the Arabian Sea is the INDUS RIVER. The variations in difference between planktonic and benthic values reflect the magnitude of the seasonal changes in surface and bottom waters through time. Figure 9. Makkah (Mecca) early trade city in Arabia that became an Islamic religious center with the Ka'bah. For half the year (April–October), the winds in this region are from the southwest, reversing in the other half of the year. Shankar et al. The intensity of the OMZ has varied through orbital and suborbital timescales and this variability is thought to be driven by changes in surfacewater productivity and the depth of winter mixing. Pakistan. travel guide. The city of Karachi had a high population growth rate of 5.3% over 1960–2010 (Singh, 2014). Denitrification and recurrent occurrence of N2 fixing microorganisms in the AS makes it a suitable global basin for testing marine nitrogen equilibrium (Naqvi, 1987). The topography of the mixed layer of the central Bay of Bengal is less predictable than in the Arabian Sea, perhaps because of undersampling, but also because this region is characterized by abundant, strong, and variable mesoscale eddies of both signs. A larger oxygen isotope difference between planktonic and benthic foraminifera during interglacials reflects the presence of a shallow thermocline, as a result of the strong summer monsoons. This rate is slightly lower than the GMSL rate over the same period. We have strong presence in major sectors such as U.A.E., Far East, South East Asia, Indian Sub-continent, Arabian Sea, and East Africa Ports and Red Sea. They provided statistical evidence, from the power-law statistics framework, that 64% (i.e., ∼0.7 mm year−1) of the observed SL trend at Mumbai over the 20th century could be induced by externally driven changes in the Indian Ocean currents. Such studies show that the seasonality was stronger during glacials and weaker during interglacials, because during glacials the southwest summer monsoon was weaker and the northeast winter monsoon stronger. The first ice skates were made from animal bones. In winter the sun’s apparent path is vertically over the Tropic of Capricorn. At the northern end of the Red Sea, ships can enter the canal and can get to the Mediterranean Sea without having to sail all around the continent of Africa. The Arabian Sea has been the historic trade route from Occident to Orient since the dawn of commerce between the cradles of civilization. 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. During the oligotrophic inter-monsoon period, surface waters are depleted of combined nitrogen thus restricting the production of phytoplankton (Bhattathiri et al., 1996). Hotspots of Relative Sea Level Rise in the Tropics, Giosan et al., 2006; Syvitski and Kettner, 2011, Khan et al., 2002; Woodworth, 2005; Church et al., 2006; Palanisamy et al., 2014, Ecological Geography of the Sea (Second Edition), Ramana, Ramprasad, Kamesh Raju, & Desa, 1993, Chaubey, Bhattacharya, Murty, & Desa, 1993. This substantiates that lower denitrification during glacial periods in the Arabian Sea could have resulted from a decrease in upwelling and the settling flux of organic material through the water column. The implication is that this spreading of the Laxmi Basin floor is exerting strong pressure on the offshore as well as onshore belts encompassing the Tertiary basins of the Maharashtra and Gujarat coastal belt, including Kachchh (Kutch) (Plate 1.4). The symbol ∗ corresponds to nonsignificant trend (P-value > 0.1). The intervening dry spells of monsoon is called ‘Breaks’ in monsoon. The rate of denitrification (Naqvi et al., 2009) in the coastal hypoxic zone is less than that in the open ocean oxygen-minimum zones (OMZ). (Reproduced with permission from Reddy, P. R. (2010). Advertisement. Sea. Therefore, the δ15N record and associated data indicate that the Arabian Sea has exhibited large, climate-driven variations in denitrification, probably forced directly by changes in the intensity of the summer monsoon and associated upwelling (Altabet et al., 2002). Some of the countries that border the Arabian Sea are Pakistan, Oman, Iran, and India. 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 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. Mumbai, with a current population of about 20 million, expects to achieve a 35% growth rate by 2025, and in Karachi, the current population of 14 million is expected to see an increase of 45% by 2025 (Kourtit and Nijkamp, 2013). The nations that share the management and use of the Arabian Sea have no comprehensive plan for conservation and management of the resources or uses of this critical area of ocean. They estimated significant RSL trends from PSMSL TGs having at least 40 years length. Arabian Sea is only a part of the Indian Ocean that is located between the Arabian Peninsula and the Indian subcontinent. Arabian Sea 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. Commercial fishing is a major activity in the Arabian Sea with the leading species fished being sardines, prawns, and mackerel. Setting up a connection between the Arabian Peninsula and the Indian subcontinent, the Arabian Sea lies in the north-west part of the Indian Ocean. The interaction between these diverse forcings is complex and results in highly variable circulation. N. Niitsuma, P.D. Globally, long-term, interannual, and decadal changes in the SL of the Arabian Sea have rarely been a subject of specific studies, probably due to the lack of historical quality data; the focus has primarily been on the regional physical oceanography of the northern Indian Ocean or that of the BoB. Minimum mixed-layer depths along this ridge are 30–40 m and south of the ridge, mixed-layer depths reach 90 m during the Northeast Monsoon. What two seas border Saudi Arabia? Off the Konkan–Gujarat Coast the floor of the 3000 m deep Laxmi Basin in the Arabian Sea is spreading. (2010) reported that around ∼79% of the nitrogen in suspended particles of surface waters in the northeastern AS was contributed from recently fixed nitrogen by Trichodesmium. (b) Carbon isotope profiles of planktonic foraminifera (δ13CP) and benthic foraminifera (δ13CB), and the difference between planktonic and benthic records (Δδ13CB–P) over last 800 000 years at ODP Site 723 in the Arabian Sea. Figure 3. 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). Its total area is 3,862,000 km (1,491,000 sq mi) and its maximum depth is 4,652 meters (15,262 ft). Pesticides and organic wastes flow untreated into the coastal waters from cities and agricultural land. As early as the 8th century and onward, Arabian and Persian mariners learned to navigate this area by using prevailing winds and the surface currents generated by the summer and winter monsoons. As denitrification proceeds, the residual nitrate in the oxygen-deficit subsurface waters become progressively enriched in 15NO3−. 7.1). M. Klose, Content Writer Answered: Jul 28, 2020. The Arabian Sea's seasonally reversing monsoons drive one of the most energetic current systems in the world and the greatest seasonal variability observed in any ocean basin (1, 2).It is the only ocean basin that fully reverses its circulation on a semiannual basis (3, 4), a phenomenon in which the Indian Ocean, the Eurasian continent, and the Pacific Ocean play important roles (). The northern Arabian Sea is one of the few regions in the open ocean where thermocline water is severely depleted in oxygen. The Maldives, officially the Republic of Maldives, is a small island nation in South Asia, located in the Arabian Sea of the Indian Ocean. Reconstruction of denitrification at centennial time scale from the coastal eastern Arabian Sea document a substantially weakened denitrification during Little Ice Age (AD 1500 to 1750), as a result weak SW monsoon (Agnihotri et al., 2008) This suggests that the denitrification process of the Arabian Sea is tightly coupled with the SW monsoon strength in both millennial and centennial time scale. 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. It is a product of the differential–intermittent uplift on these faults, predominantly in the Quaternary era. It has also been found that the lowest oxygen levels in the oxygen minimum correlates with productivity maxima in sedimentary records from the Pakistan margin. The average of 15 TGs records, obtained from PSMSL, produces an RSL rate of 2.4 mm year−1 for the period 1979–2007. Plate 1.4. This high terrigenous supply during glacials was not caused by the low sea-level stands (and larger surface area of the continents), because the maximum terrigenous supply did not occur during the maximum phase of regression. However, it only represents the climatic component of SL changes, and therefore does not take into account local subsidence that can amplify the RSL change, i.e., directly felt by the population. These cities already faced major challenges of flooding and aquifer salinization, amplified by regional SL rise. P.D. This makes it easier to discern at a glance what "makes up" a region and a province's value when considering mission goals, territorial claims, Victory cards, etc. Max. Large planktonic–benthic differences indicate a more vigorous monsoonal circulation during the summer monsoon. The situation is being further aggravated in the Indus delta along Pakistan’s coast, in Sindh province. (2014) to detect human influence on SL rise. (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. Palanisamy et al. The organic carbon record from the Indian margin suggests lower productivity during glacial periods. Which Asian desert is located in northern China and southern Mongolia? The Indus River forms a wide delta near its mouth at the Arabian Sea on which continent? Concomitantly, it is sliding under the Andaman–Nicobar Island Arc, as testified by the long deep Java Trench fringing the island arc and by the occurrence of large and great earthquakes far too often (Fig. It lies southwest of Sri Lanka and India, about 1,000 kilometres from the Asian continent. The sea is of geostrategic interest as it is the transit route for a major portion of the world's oil supply. This air flow from sea to land bring heavy rainfall to the Indian subcontinent. Another important process occurs in this specific region: the influence of the groundwater depletion, deforming the Earth’s solid surface and depressing the geoid and slowing SL rise near areas of significant groundwater loss (Veit and Conrad, 2016).
