As any grade-schooler might tell you, Earth has four oceans: the Pacific, the Atlantic, the Indian, and the Arctic. Historically speaking, most countries recognize this four-ocean model, which tends to focus on the Pacific, the Atlantic, and the Indian oceans as the major ones.

Geography, 5-8

The United States is officially bordered by three oceans: the Pacific Ocean to the west, the Atlantic Ocean to the East, and the Arctic Ocean to the north.

It’s not two oceans meeting, its glacial melt water meeting the off shore waters of gulf of Alaska. The reason for this strange phenomenon is due to the difference of water density, temperature and salinity of the glacial melt water and off shore waters of gulf of Alaska, making it difficult to mix.

The primary reason airplanes don’t fly over the Pacific Ocean is because curved routes are shorter than straight routes. Flat maps are somewhat confusing because the Earth itself isn’t flat. Rather, it’s spherical. As a result, straight routes don’t offer the shortest distance between two locations.

Gulf of Alaska

The Indian Ocean and the Pacific Ocean meet in the Gulf of Alaska, but we can say that these two oceans do not even meet together. This is because its water is never mixed into each other.

The reason the ocean is blue is due to the absorption and scattering of light. The blue wavelengths of light are scattered, similar to the scattering of blue light in the sky but absorption is a much larger factor than scattering for the clear ocean water.

Arctic Ocean

“The river water flows into the sea and decomposed organic waste like leaves of trees have mixed with sea water. Since the sea is volatile, this waste is being washed to the shore and that is the reason why the water looks black when one sees it from the beach.”

American undersea explorer Victor Vescovo has become the first person to dive to the deepest points of the earth’s five oceans, and he’s now back on dry land to reveal his discoveries. Meanwhile, his excursion to the bottom of the Molloy Trench marked the first manned dive to reach to the bottom of the abyss.

Mariana Trench

60 feet

the Dead Sea

The seabed (also known as the seafloor, sea floor, or ocean floor) is the bottom of the ocean, no matter how deep.

At 35,814 feet below sea level, its bottom is called the Challenger Deep — the deepest point known on Earth. In fact, to put it into perspective, think about the Titanic, which was found 12,600 feet below the surface of the Atlantic Ocean — nearly 2.4 miles down.

In fact, most of it is deep. Officially anything deeper than just 200 metres is considered the “deep sea”, but the average depth of the entire ocean is about 3.5km and the deepest point – the Challenger Deep in the Mariana Trench, in the western Pacific – is a little short of 11km down.

Despite its immense distance from everywhere else, life seems to be abundant in the Trench. Recent expeditions have found myriad creatures living out their lives at the bottom of the sea-floor. Xenophyophores, amphipods, and holothurians (not the names of alien species, I promise) all call the trench home.

Dr Ram says that still little is known about the lifeforms inhabiting the Trench but despite the lack of light, acidic and freezing conditions, more than 200 known microorganisms and small creatures, including crustaceans and amphipods, have been known to be living there.

The Mariana Trench is a crescent-shaped trench in the Western Pacific, just east of the Mariana Islands near Guam. The Mariana Trench contains the deepest known points on Earth, vents bubbling up liquid sulfur and carbon dioxide, active mud volcanoes and marine life adapted to pressures 1,000 times that at sea level.

If this list of scary deep sea creatures is any indication, what will be discovered could be just as terrifying if not even more frightening.

Just when you thought puppy-sized spiders were the creepiest creatures on the planet, we found a few more to give you nightmares.

Supermassive black holes are strange. The biggest black hole discovered so far weighs in at 40 billion times the mass of the Sun, or 20 times the size of the solar system. Whereas the outer planets in our solar system orbit once in 250 years, this much more massive object spins once every three months.

Fear of the ocean is actually one of several “prepared” fears, which are grounded in our survival instincts. Or, as he puts it: “The ocean’s a dangerous place.” It’s pretty justifiable to find the ocean scary because of rip currents, sharks, or the possibility of drowning. Dr.
