What are the features of the Indian Ocean?
most prominent features of the Indian Ocean is its seismically active, rugged and inverted Y shaped Mid-Indian Ridge, which is cut by numerous north-northeast trending fracture zones. The seismic Ninety-Degree East Ridge, 4800 km long and the Chagos-Laccadive Plateau are the unique features of the indian Ocean.
What is unique about ocean circulation in the Indian Ocean?
Its circulation is distinctive to the other tropical oceans in numerous ways. Unlike the Pacific and Atlantic that have sustained equatorial and eastern boundary upwelling, in the Indian Ocean the shallow upwelling of cool, nutrient-rich waters primarily occurs north of the equator and east of Madagascar1.
Why is the Pacific so dirty?
That’s when the warmer surface temperatures of the ocean move further out to sea and are replaced with deeper, colder and more sediment-rich waters. The Pacific Ocean is huge and turns a lot of water brownish-gray as a result of upwelling. Murky water is home to a lot of marine life like jellyfish, too.
Why is the Ocean 2 different colors?
The red, yellow, and green wavelengths of sunlight are absorbed by water molecules in the ocean. In coastal areas, runoff from rivers, resuspension of sand and silt from the bottom by tides, waves and storms and a number of other substances can change the color of the near-shore waters.
Why are colder oceans darker?
The molecular density of cold ocean water are higher then warmer water. This is why they appear dark.
Why is the North Sea so dark?
In contrast cold waters are dirty and full of life due to the upwelling of water from the ocean bottom. All that dirt and all the life it supports absorbs sunlight very fast. That produces an ocean that is very dark colored, and where the blue wavelengths are muted by the reds and greens to produce a muddy blue-gray.
Why is Blackpool sea so dirty?
The turbulence picks up particles of sand and beach material and holds it in suspension in the sea water. That’s why it looks so brown most of the time. If you were to collect a bucket of sea water and leave it to stand for long enough, the fine silt would settle out.
Why does the North Sea look dirty?
“The main reason is the sediment suspended in the water all the time, very common in shallow seas, and the huge amount of large shipping we have moving through it and stirring it up,” he said. “It doesn’t mean the water is ‘dirty’ but that is what gives it its colour.
Is ocean water dirty?
According to the Centers for Disease Control and Prevention , ocean water can be contaminated with animal waste, sewage spills, stormwater runoff, fecal matter, and germs from the rectal areas of swimmers.
Is there poop in water?
swim. Also if you have diarrhea or have recently had diarrhea, please don’t lower your infectious body into a body of water shared with other people. Of course, outdoors in lakes, ponds, rivers, and the ocean, poop can get into the water even without someone actively pooping in it.
Is it safe to swim in the ocean at night?
It isn’t safe to swim in the ocean at night. Swimming in the ocean at night can pose a greater risk than swimming during daylight hours, especially for inexperienced swimmers. This is due to the loss of vision in the darkness, the lack of people nearby, and the nocturnal behavior of ocean predators.
