Context: The IMD has forecast a low-pressure system forming over the east-central Arabian Sea, likely to intensify into a depression in the next 36 hours.
About Arabian Sea:
• Location: The Arabian Sea is a northwestern extension of the Indian Ocean, bordered by India to the east and the Arabian Peninsula to the west.
• Neighbouring Nations: Coastal countries: India, Pakistan, Iran, Oman, Yemen, and Somalia. Key maritime links: Gulf of Oman (to Persian Gulf) and Gulf of Aden (to Red Sea).
• Coastal countries: India, Pakistan, Iran, Oman, Yemen, and Somalia.
• Key maritime links: Gulf of Oman (to Persian Gulf) and Gulf of Aden (to Red Sea).
• Indian Coastal States: Indian states bordering the Arabian Sea include: Gujarat, Maharashtra, Goa, Karnataka, Kerala, and Lakshadweep UT.
• Geographical Features: Depth: Average depth ~2,734 m and max depth at Wheatley Deep ~5,803 m Major Submarine Features: Carlsberg Ridge (seismic, mid-ocean ridge) Murray Ridge, Somali and Arabian Basins Indus submarine canyon and abyssal cone Key Islands: Socotra (Yemen), Kuria Muria Islands (Oman), Lakshadweep (India) Role in Monsoon: Monsoon Influence: Southwest monsoon winds (April–November) gather moisture from the Arabian Sea, triggering heavy rains in India. Upwelling near the Somali and Arabian coasts aids in nutrient cycling and monsoon onset. Ocean Currents: Hosts the Somali Current, one of the fastest ocean currents (~13 km/hr), seasonally reversing with monsoons. Drives clockwise circulation during summer and weakens during winter monsoon. Sediments & Marine Geology: High sedimentation from the Indus River. Known for ferromanganese nodules, hydrogen sulfide zones, and polymetallic sulfides.
