Mariana trench named after

The Mariana Trench hosts the Challenger Deep, the deepest known part of all of the earth's oceans. Researchers are eager to learn more about it by way of scientific discovery, all the while calling for its protection and preservation. As they seek to better understand the Mariana Trench and Challenger Deep, could they help in future life-saving breakthroughs as well? 5. Description The Mariana Trench is located in the Western Pacific ocean and east of the Philippines. The crescent shaped trench is about 124 miles east of Mariana Islands. According to the National Geographic, the Mariana Trench is over 1,500 miles long, and 43 miles wide on average. The trench’s deepest point is the Challenger Deep which according to the National Oceanic and Atmospheric Administration (NOAA) is 36,200 feet or about 11 kilometers in depth. The Challenger Deep is around 200 miles southwest of 4. Historical Role Depths of the Mariana Trench were first explored in 1875 by a British H.M.S Challenger ship during an oceanographic cruise. Scientists in the ship recorded a depth of about 8 kilometers using a weighted sounding rope, according to National Geographic. The Mariana Trench deepest point the Challenger Deep was named after the H.M.S Challenger ship. In 1951, the H.M.S Challenger II ship returned with an echo sounder and measured a depth of about 11 kilometers. Only two humans in history have descended into the Challenger Deep depths. In 1960, Jacques Piccard and Navy Lieutenant Don Walsh (...

We know more about the surface of the moon than about the ocean floor. Scientists estimate that 91 percent of life under the sea hasn’t been discovered yet and more than 80 percent of the ocean has never been explored. What we do know about the ocean makes it almost more mysterious. It’s an alien landscape, complete with undersea mountain ranges and trenches deeper than Mount Everest is tall, home to a glorious nightmare carnival of weird, often glowing animals. And most of what we know has only come to light in the last 150 years, starting with the expedition of HMS Challenger . From 1872 to 1876, the 200-foot-long warship was repurposed as a floating lab for the world’s first large-scale oceanographic expedition, circumnavigating the globe and dredging up samples of never-before-seen creatures from the ocean floor. The Challenger explorers brought to light thousands of new species and revealed the oceans to be a place of startling depths and untold wonders. Scientists today still rely on the Challenger findings to study everything from seashells to climate change. Sampling Another World The Challenger expedition was inspired, in part, by that age-old motivation: to prove somebody wrong . In 1843, a naturalist named Edward Forbes posited that “the number of species and individuals diminishes as we descend, pointing to a zero in the distribution of animal life as yet unvisited” at depths below 1,800 feet. But several small expeditions hinted that he couldn’t be right: HMS ...

Trieste is a submarine that was built in the early 1960s. It was designed to be able to operate at great depths, and was the first submarine to reach the bottom of the Mariana Trench. Trieste was decommissioned in 1984, and is now on display at the Museum of Science and Industry in Chicago. The Trieste, with two people aboard, was the first vehicle to reach the Mariana Trench. There is a segment of the ocean beneath the surface known as the Why Is The Bathyscaphe Trieste Famous? Picture source: pinimg.com The bathyscaphe Trieste is most famous for being the first vessel to reach the deepest known point on Earth, the Challenger Deep in the Mariana Trench. On January 23, 1960, the Trieste carrying Swiss oceanographer Jacques Piccard and US Navy Lieutenant Don Walsh reached a depth of 10,916 meters (35,813 feet), a feat that was not repeated for over 50 years. The Trieste remains the only bathyscaphe to have reached the Challenger Deep. The city of Trieste had a long and fascinating history before being annexed by Italy in 1920. As a port city on the Gulf of Trieste, it was once a key commercial and strategic center under Austrian rule. After World War I ended and Austria-Hungary dissolved, the city of Trieste was transferred to Italy along with the rest of the Julian March (the Venezia Giulia). As a result of the annexation, the city lost both strategic and commercial significance. It is still a significant port city in Friuli-Venezia Giulia and serves as the capital of the ...

You may have already heard that the Mariana Trench is the deepest part of the ocean, but what exactly is it? While coral reefs, kelp beds, and other coastal areas might be reasonably familiar, the Undoubtedly, the most impressive of all the terrain beneath the waves has to be the Mariana Trench. This article will answer all your questions, starting right at the beginning. • • • • • • • What Is the Mariana Trench? Deep below the surface, at an area in the Western Pacific Ocean between The Philippines, Papua New Guinea, and Japan, the crescent-shaped Mariana Trench dramatically opens up the seabed and is the deepest oceanic trench on Earth. To make it easier to imagine, we can think of oceanic trenches like canyons on land, but they’re considerably longer and wider. Why Is It Called the Mariana Trench? The deepest part of the world’s ocean was named after the nearby These islands were named after the Spanish However, it’s worth noting that the first humans arrived from the Philippines significantly earlier, between 1500 to 1400 BC. It is unclear who specifically came up with the name “Mariana Trench.” However, the earliest known reference was in a report by the British survey ship HMS Challenger (known as Challenger II.) The Royal Navy team explored the trench “using explosives and a hand-held stopwatch, a wire-line sounding machine with a 40-lb weight, and an echo sounder” in 1951. Before that, the trench was discovered during an expedition of the original in March 1875. Th...

To even comprehend all the weird stuff that’s going on in the Mariana Trench, we must first understand its sheer size. It’s easy to think that the place is just some deep, watery hole where a few creepy bioluminating critters hang about. In reality, however, the Mariana Trench is absolutely massive . It’s no less than 1,580 miles long and 43 miles wide, which understandably makes its exploration an incredibly daunting task even if you ignore the water pressure and the terrifying-looking lifeforms that lurk within its depths, which extend all the way down to roughly 36,000 feet below the surface at the trench’s deepest point, the Challenger Deep. The Trench is technically U.S. territory, but since a giant, super-deep ocean hole that contains all sorts of strange ecosystems is obviously fairly vulnerable to human tampering, President 9. The Mariana Trench mystery sound One of the strangest things that have emanated from the Mariana Trench hasn’t been a frightening sea monster, though we’d be surprised if the option isn’t on the table whenever the mysterious “bio-metallic” sound that sometimes emanates from the trench is heard. Marine researchers have dubbed this almost mechanical, “twangy” noise “Western Pacific Biotwang,” and it first turned up in 2014 when scientists recorded ocean sounds near the Mariana Trench with diving robots called “passive acoustic ocean gliders.” The complex, 3.5-second sound turned up several times during the research period, and while it seemed m...
