What is meant by ocean current?

The term “current” describes the motion of the ocean. Ocean currents are driven by wind, water density differences, and tides. Oceanic currents describe the movement of water from one location to another.

Does the ocean currents flow near the surface of the continental shelf?

This chapter discusses the different aspects of ocean currents over the continental slope. Continental slopes underlie some 12% of the world ocean’s surface area. Coastal currents driven by density differences due to river runoff are common on continental shelves but reach to the upper slope only in a few places.

How do ocean currents affect continental margins?

Currents over the Continental Shelf tend to flow southeastward in summer, causing nutrient-rich cool waters to upwell onto the shelf. The abrupt steeping of the slope topography in the northern part of the study area also causes northwestward-flowing slope currents to turn toward the deep ocean.

What is continental shelf in the ocean?

A continental shelf is the edge of a continent that lies under the ocean. Continents are the seven main divisions of land on Earth. A continental shelf extends from the coastline of a continent to a drop-off point called the shelf break.

What is called continental shelf?

The term “continental shelf” is used by geologists generally to mean that part of the continental margin which is between the shoreline and the shelf break or, where there is no noticeable slope, between the shoreline and the point where the depth of the superjacent water is approximately between 100 and 200 metres.

What is an example of a continental shelf?

Example of a Continental Shelf Landform: Siberian Shelf, Arctic Ocean. The picture is of Southeast Florida Continental Shelf (It is under water). It is smaller than the side in the Gulf of Mexico.

What is the deepest of all ocean deeps?

The deepest part of the ocean is called the Challenger Deep and is located beneath the western Pacific Ocean in the southern end of the Mariana Trench, which runs several hundred kilometers southwest of the U.S. territorial island of Guam. Challenger Deep is approximately 36,200 feet deep.

How deep in the ocean can you go?

The deepest point ever reached by man is 35,858 feet below the surface of the ocean, which happens to be as deep as water gets on earth. To go deeper, you’ll have to travel to the bottom of the Challenger Deep, a section of the Mariana Trench under the Pacific Ocean 200 miles southwest of Guam.

What is the shallowest ocean?

The Arctic Ocean is the smallest and shallowest of the world’s five major oceans. This water body is completely surrounded by the continents of Asia, North America, Europe and the island of Greenland.

What is the third deepest ocean?

The deepest point here lies at a depth of 8,378 ± 5 meters. In the Indian Ocean, the third-largest of the world’s oceans, the deepest feature is a yet unnamed 7,187 ± 13 meters deep point within the Java-Trench, not as previously believed the Dordrech Deep, with 7,019 ± 17 meters.

What is the deepest point in the ocean?

11,022 m

Which ocean is the deepest Atlantic or Pacific?

But just how deep is the Mariana Trench? First off, here are the average depths of the earth’s oceans; the Arctic Ocean is 1,038 meters (3,407 feet) deep, the Indian Ocean is 3,960 meters (12,990 feet) deep, the Atlantic Ocean is 3,339 meters (10,955 feet) deep and the Pacific Ocean is 4,188 meters (13,740 feet) deep.

What is the difference between the Atlantic and the Pacific Ocean?

The Atlantic Ocean is known to have higher sea surface salinity than the Pacific Ocean at all latitudes. This asymmetry may be a result of salt transport in the ocean or an asymmetry in the surface water flux (evaporation minus precipitation; ) with greater over the Atlantic than the Pacific.

Can you survive at the bottom of the ocean?

You can’t breath at the bottom of the ocean. If you can’t breath, your body won’t stay alive for more than about 30 minutes. The pressure from the water would push in on the person’s body, causing any space that’s filled with air to collapse. (The air would be compressed.)

What are ocean currents short answer?

An ocean current is any more or less permanent or continuous, directed movement of ocean water that flows in one of the Earth’s oceans. The currents are generated from the forces acting upon the water like the earth’s rotation, the wind, the temperature and salinity differences and the gravitation of the moon.

Why ocean currents are formed?

Ocean currents can be caused by wind, density differences in water masses caused by temperature and salinity variations, gravity, and events such as earthquakes or storms. These currents move water masses through the deep ocean—taking nutrients, oxygen, and heat with them.

Can you get pregnant from a whale?

The answer is no. Because whales are marine mammals, the females carry the offspring in their wombs and have live births! However, since whales are fully aquatic mammals, how whales give births is much different than the births of terrestrial and semi-aquatic animals.

What Colour is whale sperm?

They are uniformly grey in colour though may appear brown in sunlight (the “Great White Whale” of Melville’s novel, if such an animal existed, was an albino, and white sperm whales have been reported in reality as well).

Is foam in the ocean whale sperm?

No, Sea Foam is not whale sperm. Sea Foam created by the agitation of sea H2O containing high concentrations of dissolved organic matter including proteins, lignins & lipids derived from sources such as the offshore breakdown of algal blooms. These compounds can act as surfactants or foaming agents.

Is whale poop worth money?

(Modern science says the waxy substance is more like a whale gallstone, or whale poop.) Although it sounds pretty repellant, ambergris is actually worth big bucks — the chunk that these guys stumbled upon weighed 176 pounds (80 kilograms) and was allegedly worth nearly $3 million.

Can whales fart?

Yes, whales do fart. I’m yet to experience this, but I know of some lucky scientists who have seen a humpback whale fart. They tell me it looks like bubbles coming out underneath its body near the tail. That’s where the whale bum is — the smellier blowhole.

Why is whale vomit so expensive?

Ambergris has been called the treasure of the sea and floating gold. It is hugely valuable – it commands a higher price than gold. This is because it is highly prized as a fixative and ingredient in fine perfumes. Ambergris is only produced in the guts of sperm whales, which vomit the substance occasionally.

Do expensive perfumes contain whale poop?

Perfumers covet a rare kind of whale poop known as ambergris. Though it develops in the intestine of sperm whales, it produces a prized scent used in high-end fragrances. This is ambergris. It might look like a rock, but it’s actually a rare kind of whale poop.

Has anyone been eaten by a whale shark?

During the dive, the largest whale shark in the area began to act differently. It appeared to be swimming directly at divers with its mouth wide open. The diver recalls being hit hard by the whale shark. Then the diver was sucked into the mouth of the whale shark — head first — and half-swallowed up to her thighs.

What is the most expensive part of a whale?

Ambergris is formed from a secretion of the bile duct in the intestines of the sperm whale, and can be found floating on the sea or washed up on coastlines.

What does sperm whale poop look like?

In addition to feces, the digestive system of sperm whales produces ambergris, a solid, waxy, flammable substance of a dull grey or blackish color which can be found floating on the sea or washed up on the coast.

How large is whale poop?

200 litres

Why is sperm whale poop expensive?

Kemp, the author of “Floating Gold: the Natural (and Unnatural) History of Ambergris” (University Of Chicago Press, 2012), notes that the stuff commands a high price because “only one percent of the 350,000 sperm whales can actually make it,” he told ABC News. “Because it’s so rare, it’s very valuable.”

How long can you survive inside a whale?

DECCAN CHRONICLE. According to the man he stayed inside the whale for three days and three nights.

What is the biggest animal poop?

blue whale

How big is a blue whale poop?

A blue whale is capable of producing up to 200 litres of excrement with each bowel movement, which in itself plays a vital role in ensuring a constant food supply.

Can a human get swallowed by a whale?

While the veracity of the story is in question, it is physically possible for a sperm whale to swallow a human whole, as they are known to swallow giant squid whole. However, such a person would be crushed, drowned or suffocated in the whale’s stomach. Like ruminants, the sperm whale has a four-chambered stomach.

What color is blue whale poop?
