When that carbon is absorbed, a series of chemical reactions takes place that produces more hydrogen ions and leads to more acidic waters. Oceans, which absorb about 30 percent of the CO 2 released into the atmosphere, are also highly susceptible to the changes taking place in a warming world. Ocean acidification and ‘the blob’īurning fossil fuels and releasing carbon dioxide into the air doesn't just alter the makeup of our atmosphere. Scientists know little about many of these creatures and the roles they may play in the global ecosystem because they are so hard to study. Yet the deep sea is home to a diverse group of sea creatures with mysterious lives, from glowing lures to huge eyes. Creatures in the deep sea exist in waters with zero light, crushing pressure, and conditions no human could ever survive. Scientists are just beginning to learn about life in the deepest parts of the oceans. Today, scientists periodically send remotely operated vehicles to the bottom of the trench for various research purposes. Navy submersible, and film director and explorer James Cameron made a solo trip in 2012. Humans descended into the Challenger Deep in 1960 inside a U.S. The deepest point in the trench is called Challenger Deep, at 36,000 feet down. Everest is tall, reaching down roughly seven miles. It's the deepest known spot on the planet-deeper than Mt. The Mariana Trench is one such deep ocean trench that sits along the Ring of Fire in the Mariana Archipelago east of the Philippines. Learn why healthier oceans means a healthier planet, and how you can help. The oceans cover 72 percent of the Earth and supply half its oxygen, and it’s in danger. The subduction of tectonic plates-when a plate slides beneath another one-in certain areas also helps form deepwater trenches. The resulting chain of volcanoes is roughly 25,000 miles long and springs to life where the Pacific tectonic plate slides against or collides into the other tectonic plates that circle it. The Pacific basin is called the “ Ring of Fire” because of the area of earthquake and volcanic activity around its edges. The storms feed on the energy of warm water, making the Pacific a powerful breeding ground for them. Hurricane is used in the eastern Pacific, typhoon in the northwestern Pacific, and cyclone in the southwestern Pacific. Hurricanes, typhoons, and cyclones are actually different names for the same weather pattern. At its strongest, the storm’s winds topped 165 miles per hour, uprooting trees, destroying homes, and causing deadly mudslides. It hit the Philippines in late September before dissipating over mainland China. For example, in 2018 the strongest storm of the year was Super Typhoon Mangkhut. The Pacific Ocean stirs up some of the strongest hurricanes ever seen. Find out more about the ocean, including the consequences of climate change. Oceans are the planet’s largest habitats and also help to regulate the global climate.
