Ocean Trenches - Woods Hole Oceanographic Institution
2019年11月7日 · The deepest trench in the world, the Mariana Trench located near the Mariana Islands, is 1,580 miles long and averages just 43 miles wide. It is home to the Challenger Deep, which, at 10,911 meters (35,797 feet), is the deepest part of the ocean. The Tonga, Kuril-Kamatcha, Philippine, and Kermadec Trenches all contain depths greater than 10,000 ...
Ocean Zones - Woods Hole Oceanographic Institution
The region extending from 6,000 to 11,000 meters is called the hadal, or hadalpelagic, zone after Hades, the Greek god of the underworld. They occur only in trenches across the…. The ocean water column is made up of five zones: the sunlight (epipelagic), twilight (mesopelagic), midnight (bathypelagic), abyssal (abyssopelagic) and hadal zones ...
Ocean Trenches – Woods Hole Oceanographic Institution
Nereus Soars to the Ocean’s Deepest Trench. It took a village of engineers to build a completely new type of unmanned deep-sea robot that can reach the deepest part of the ocean. On May 31, 2009, a….
Nereus Soars to the Ocean’s Deepest Trench
2009年6月4日 · Soars to the Ocean’s Deepest Trench. It took a village of engineers to build a completely new type of unmanned deep-sea robot that can reach the deepest part of the ocean. On May 31, 2009, a team of engineers at Woods Hole Oceanographic Institution (WHOI) celebrated as the unique vehicle called Nereus dove to 10,902 meters (6.8 miles) in the ...
A new way to discover life in the ocean’s hadal zone
2024年3月14日 · In 2020, Weston and her then-PhD supervisor, Alan Jamieson, discovered a new species of amphipod nearly 7,000 meters (22,965 feet) deep in the Mariana Trench in the western Pacific. After analyzing its gut contents, they were surprised to find a plastic microfiber and decided to name the organism Eurythenes plasticus to raise awareness of the ...
Mid-ocean Ridges - Woods Hole Oceanographic Institution
2020年11月10日 · At nearly 60,000 kilometers (37,000 miles) long, the mid-ocean is the longest mountain range on Earth. It formed and evolves as a result of spreading in Earth’s lithosphere—the crust and upper mantle—at the divergent boundaries between tectonic plates. The vast majority of volcanic activity on the planet occurs along the mid-ocean ridge ...
Abyssal Zone - Woods Hole Oceanographic Institution
2021年2月25日 · What is the abyssal zone? Earth’s vast oceans run deep, bottoming out around 4,000 meters (13,123 feet) in most places, although trenches can form underwater canyons extending another 7,000 meters (22,965 feet). The seafloor and water column from 3,000 to 6,500 meters (9,842 to 21,325 feet) depth is known as the abyssal zone, or the abyss.
Did you know: How do ocean robots take the pressure?
In 1998, operators of a Japanese remotely operated vehicle (ROV) named KAIKO were surveying the depths of the Mariana Trench in the Pacific Ocean when they spotted something shocking on the vehicle’s camera: a single-use plastic bag floating idly some 6.7 miles (10.8 kilometers) down at the Earth’s deepest point.
Tsunamis in the Caribbean? It’s Possible.
2005年3月25日 · The Puerto Rico Trench is about 900 kilometers (560 miles) long and 100 kilometers (60 miles) wide, and it runs roughly parallel to the northern coast of Puerto Rico, about 75 miles offshore. It is the deepest point in the Atlantic Ocean, descending 8,340 meters (27,362 feet) below the sea surface.
Hadal Zone - Woods Hole Oceanographic Institution
2024年6月10日 · The hadal zone is characterized by extreme depth and pressure, temperatures that hover just above freezing, and complete darkness—at least in terms of light from the sun. Bioluminescence allows organisms in the ocean depths to communicate. Walls of trenches are steep and descend through a gradient of depths and pressures, creating a variety ...
