Covering the entire expanse of area south of Indian subcontinent, Indian Ocean is a vast feature of earth’s geographical blue print. But that’s not all that makes interesting facts about Indian Ocean.
Find out some interesting facts about the Indian Ocean.
1. Covers 20% of the Earth Surface
The first bit of Indian Ocean information that gets hold of anyone’s attention is its size. And it does not just look huge, it is huge. Covering almost 20% of earth’s total surface, Indian Ocean makes a huge contribution to the water load of the world.
Owing to its huge size, Indian Ocean has a whooping volume of 292,131,000 cubic kilometers, with an average depth of 3890 meters.
2. Several Continents by its sides/ Unique Location
Indian Ocean is bound by a number of continents on each side with Indian subcontinent towards the north, Africa towards west, The Sunda islands and Australian lands towards east and Antarctica towards south. The geographical facts about Indian Ocean depict the diversity of this Ocean through 57 islands groups, 16 African countries and 18 Asian countries being connected directly through its waters. Many other smaller ports or larger cities are connected indirectly through navigational options of this ocean.
3. The Highest Point is at the Sea Level Itself
Owing to the depth of this ocean, it is interesting Indian Ocean information that the lowest part this ocean is about 7,258 m deep lying on the Java Trench of the Sunda Shelf while its highest point is at the sea level.
4. Limited Marine Life
A rather interesting bit of information on the Indian Ocean is its limited marine animal life which is due to higher water temperature of this ocean. This ocean is the warmest ocean of the world and offers little scope to plankton and other species for growth.
5. Has Unique Chemical and Physical Properties
This ocean holds a unique place owing to its properties. As mentioned in the Indian Ocean facts, the water here has highest concentration of dissolved and floating hydrocarbons, has maximum negative water balance and is single source of water of highest and lowest salinity levels.
6. Has Several Tectonic Plate Boundaries
What is probably one of the little known facts about the Indian Ocean is that it bears many tectonic plate boundaries including the Rodrigues Triple Point where African, Indo-Australian and Antartic continental plates merge.
7. Has Lowest Oxygen Content
Waters in the Indian Ocean have one of the lowest oxygen content of the world owing to greater evaporation rate in this ocean than its run off or precipitation influx. This makes life growth in Indian Ocean rather unique.
8. 6000km of River Run
This ocean receives about 6000 km of river run off from various parts including rivers like Ganges and Brahmaputra- two of the largest rivers. Due to the closeness to equator, the evaporation rate here remains considerably high.
9. Has World’s Most Important Ports
Indian Ocean has ports that belong to different continents. Chennai, Mumbai and Kolkata are the Indian ports of this ocean while Colombo of Sri Lanka, Durban and Richards Bay in South Africa, Jakarta in Indonesia and Melbourne in Australia make the other important ports of this ocean.
These ports are important trade points in their respective countries and globally too. A part of this can be attributed to the Indian Ocean’s store of heavy minerals and off shore deposits.
10. Oil Deposit that Accounts to 40% of World Production
Indian Ocean has its own contribution in the world trade. Besides the navigation routes and mineral deposits, this ocean also has many oil deposits which make about 40 percent of total world production.
11. Has a Submerged Continent
An interesting trivia from Indian Ocean facts is the discovery of a submerged continent in this ocean named- the kerguelen Plateau’ which is believed to be of volcanic origins.
