Despite the fact that we’re all inundated with stories of oceans and lakes both adventurous and horrific, “the depths,” so to speak, all tend to blend together. In a new video, animator and YouTuber MetaBallStudios helps to tease apart the dark waters of the world. And if you think you know how deep the ocean really is, you may need to think again.

Despite the fact that we’re all inundated with stories of oceans and lakes both adventurous and horrific, “the depths,” so to speak, all tend to blend together. In a new video, animator and YouTuber MetaBallStudios helps to tease apart the dark waters of the world. And if you think you know how deep the ocean really is, you may need to think again.
MetaBallStudios (or MBS), a Spanish animator whose real is name is Alvaro Gracia Montoya, recently posted the above video to his channel. For those unfamiliar, MBS has cranked out countless animated comparison videos before. The animator has, for example, compared the sizes of various spaceships from Star Wars. As well as how big various comets in our solar system are.
In this comparison, MBS goes for depth instead of his usual size angle. The video begins with the Sea of Azov, which is in Eastern Europe and has an average depth of only 23 feet. From there, MBS slowly works down into deeper and deeper bodies of water, providing familiar structures and event sites as references. At about 90 seconds in, for example, MBS shows that the average depth of the Timor Sea is 270 feet deeper than the Eiffel Tower is tall. (That would be over 1,060 feet.)

As the comparison continues, the depths become more and more dizzying. The average depths of the Argentine Sea, the Arctic Ocean, and the Black Sea all cluster around 4,000 feet deep. Which seems deep, until the animation pulls back, revealing depths that grow to tens of thousands of feet. With the Mediterranean really bringing the “abyss staring into you” factor to 11 with a depth of more than 17,000 feet.
The Atlantic Ocean crushes that depth, however, deepening in(?) at a whopping 27,000 feet deep. For reference, that’s approximately as deep as Mount Everest is tall.

The deepest floor of any ocean on Earth, however, is the Mariana Trench, which is in the western Pacific Ocean. The trench, which is home to alien crustaceans and sounds that will send chills down your spine, is an astounding 36,000 feet deep. What’s just as astounding, however, is that explorers have visited there and sadly found plastic waste.

Largest underwater eruption on record spawned a new volcano

Largest underwater eruption on record spawned a new volcano
On May 10, 2018, seismic rumbles began between the East African and Madagascar rifts, culminating in a magnitude 5.8 earthquake five days later.
Shortly after, researchers became aware that a volcanic event had occurred 50 kilometres off the eastern coast of the French territory Mayotte, situated between Africa's east coast and northern Madagascar.
A research team investigated a few months later - and they found a new volcano, one that hadn't been there before the earthquake.
"This is the largest active submarine eruption ever documented," the paper says - and the seismic activity is what spawned the new mountain, which rises 820 metres from the seafloor.
The new feature will help scientists better understand what happens deep in the earth.
The mountain isn't the only thing the French team discovered. When they began their survey in early 2019, several seismometers and sonar were used to take measurements. Between February 25 and May 6, 2019, 17,000 seismic events ranging in depth from 20 to 50 km below the seafloor were recorded. This is unusual, the researchers say, because most earthquakes are shallower than that.
The data helped the scientists paint a picture of how the new volcano may have come to be. The findings suggest a magma reservoir in the asthenosphere was drained up through the crust after tectonic processes damaged the layer above the asthenosphere, which is called the lithosphere.

This event likely caused "swarms" of earthquakes.
As of May 2019, the volume of the new volcanic feature is between 30 and 1,000 times larger than what's believed to be in other deep-sea eruptions.
The findings are detailed in a new paper published in the journal Nature Geoscience.
