25 Facts You Should Know

For weight and depth, the Pacific Ocean is the biggest in the world. In addition to covering more than a third of the planet’s surface, it also holds half of the planet’s water. The North Pacific, as well as the South Pacific, usually are separated artificially by the equator’s line. After passing the Panama Isthmus of Darien, Spanish navigator Vasco Nunez de Balboa discovered the South Sea in 1513. Portugal’s Ferdinand Magellan gave it its present name in 1520 on his first voyage around the globe on behalf of the Spanish crown. Spanish Juan Sebastian Elcano also participated.

What Is The Origin Of The Term “Pacific Ocean”?

Spanish explorer Ferdinand Magellan set out in 1519 to find a westward path to the Spice Islands through South America, a trip that took him across the Atlantic Ocean. Before long, his little fleet had crossed the Straits of Magellan and reached an unknown ocean in November 1520. Because of the tranquility and quiet of the sea at the time, he named this body of water the Pacific.

They believed the Spice Islands were within striking distance when Magellan and his men crossed the Pacific Ocean. Their goal was still hundreds of kilometers away, and they didn’t realize it. They’d traveled into the world’s most enormous ocean. The Pacific Ocean is the biggest of the world’s ocean basins, covering 59 million square miles and contains more than half of the planet’s free water. The Pacific Ocean basin is large enough to accommodate all seven continents.


Monsoons are rain-bearing winds linked with low-pressure systems that form across tropical Asia in the summer when the air masses are heated. This low-pressure system influences trade winds from both hemispheres. A colder continent causes an increase in Asian high-pressure systems, which bolsters the Northern Hemisphere trade winds. Continental forces associated with dryness and cold and marine effects associated with moisture and heat produce significant seasonal variations in western Pacific weather.

Little cloud cover and mild precipitation are standard in the trade wind belts. Trade winds from the Northern and Southern hemispheres meet in the equatorial area, which experiences calms known as the doldrums. Trade winds along the western coastlines of the American continent cause low, heavy clouds and fog to build widely because of upwellings of cold, underground water.

25 Fascinating Facts


1. The Pacific Ocean is sandwiched between the Americas towards the east and the Asian as well as Australian continents to the west of the basin. Concerning geography, it’s easy to see how the North Pacific Ocean and South Pacific Ocean are separate spheres of influence.


2. Pacifism is a core value of the Pacific Ocean name. Magellan gave his name to the Pacific Ocean, which he discovered and named after himself. He dubbed it “mar pacific,” which translates to “quiet sea” in Spanish.


3. Known as the Ring of Fire, Pacific Ocean volcanoes create a ring encircles the ocean basin. This region is prone to earthquakes and other natural disasters because of the interaction between the tectonic and oceanic plates. The movement of the latter may cause tsunamis. The most famous eruption, which happened in 1883 with Krakatoa, killed about 37,000 people and was impacted by many more by earthquakes, ash and dust cloud, and tsunamis.

4. In terms of total surface area, the Pacific Ocean surpasses all others. More than a third of the planet’s surface is covered by it. If you put together the landmasses of every continent, it would be even more significant than this one.


5. The Pacific Ocean is the deepest in the world. The Challenger Deep inside the Mariana Trench is one of the deepest trenches in the world. The HMS Challenger investigated this trench in 1875.


6. The Pacific Ocean basin is where the ring of fire is situated on Earth’s surface. The basin’s name derives from the ring of volcanoes that surrounds it. This region is prone to earthquakes because of volcanic activity and tectonic plate movement. More than 75,000 volcanoes dot the Pacific Ocean.


7. Temperatures in the Pacific Ocean may fluctuate significantly. The warmer the water, the closer to the equator it is. The temperature of the water near the poles drops below freezing!


8. Most of the world’s islands may be found in the Pacific Ocean, including the Hawaiian island of Hawaii. The Pacific Ocean is home to more than 25,000 different islands.

9. Around one inch is being taken out of the ocean every year. Underwater plate tectonics is to blame for this. Despite this, the Atlantic Ocean increases at the same rate every year throughout the basin.


10. Additionally, the Pacific Ocean is home to a plethora of Atolls. Coral reefs surround a lagoon on an Atoll, a coral island. Only warm-water atolls can be found in the world’s oceans.


11. The Great Barrier Reef of Australia is located in the Pacific Ocean. This 1,429-mile-long reef system is the world’s most extensive coral barrier reef system. As a result, it has been designated a UNESCO World Heritage Site.


12. Every year, the Pacific Ocean declines by one inch! Tectonic plate motion is to blame for this. There is a constant increase in the size of the Atlantic Ocean each year!


13. Pacific Ocean pollution has surged by more than 100-fold during the previous four decades. Northeastern Pacific Ocean pollution is the worst. Small pieces of plastic floating in the water are the primary cause of water pollution, contaminating the surrounding ecosystem and putting animals at risk. It has also been contaminated by satellite debris, such as Mars 96, that broke apart across 200 miles of ocean and affected Chile and Bolivia.


14. 190 million years ago, the Pacific Ocean began to develop.


15. The Pacific Ocean’s second-largest island, New Guinea, is a volcanic island.


16. A Dutch adventurer found Easter Island on April 1st, giving it the name “Easter Island” in honor of the holiday.

17. The Pacific Ocean is the world’s most densely populated ocean, with more than 25,000 islands. Depending on the tides and earthquake activity, the population may fall as low as 20,000.


18. The Mid-Oceanic Ridge, the world’s most extended mountain range, sits under the surface of the Pacific Ocean.


19. New Zealand and Australia’s continental shelves are home to vast petroleum and natural gas reserves.


20. At 165 million square kilometers, the Pacific Ocean accounts for nearly a third of the planet’s surface. In terms of total area, it dwarfs the world’s 148 million square kilometers.


21. The ocean is made up of salt water, which varies in salinity based on your location. In comparison to the equator, the seas are saltier in the southeast. According to experts, salinity levels have dropped significantly in central ocean basins due to heavy rains.


22. According to scientists, sea levels have been increasing at a pace of ten millimeters each year over the last two decades. Small, uninhabited Pacific islands near the Solomon Archipelago have been lost due to this. People on larger inhabited islands are also being forced to relocate because of the loss of their coastal holdings.


23. Kelly Walsh, Walsh’s 52-year-old son, made the dive in 2020, 60 years after his father. He and his team scoured the ocean depths in a 12-ton two-passenger submersible named Limiting Factor.


24. Satellites often crash in the Pacific Ocean. Fobos-Grunt, Mars 96, and the Upper Atmospheric Research Satellite are just a few of the spacecraft that have ended up in the water. Some debris may survive after re-entering the Earth’s atmosphere. Hydrazine, plutonium, and nitrogen tetroxide, to name a few, may be found in these.


25. There will be 1.25 million metric tonnes of wastewater at the Fukushima nuclear facility by 2021. There is a shortage of storage capacity for these tanks on the site. Japan’s government approved a 30-year term for this water to be disposed of in the Pacific.
