- Ocean Trenches - Woods Hole Oceanographic Institution
Ocean trenches are steep depressions exceeding 6,000 meters in depth, where old ocean crust from one tectonic plate is pushed beneath another plate Trenches make up the world's hadal zone
- Ocean Trenches – Woods Hole Oceanographic Institution
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…
- Hadal Zone - Woods Hole Oceanographic Institution
The hadal zone occurs only in trenches, which can extend to 11,000 meters deep (36,000 feet) Hadal regions combined across all oceans make up an area about the size of Australia
- Ocean Zones - Woods Hole Oceanographic Institution
The ocean water column is made up of five zones: the sunlight (epipelagic), twilight (mesopelagic), midnight (bathypelagic), abyssal (abyssopelagic) and hadal zones (trenches)
- Abyssal Zone - Woods Hole Oceanographic Institution
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 Sunlight doesn’t penetrate to these depths, so the
- Mid-ocean Ridges - Woods Hole Oceanographic Institution
What are mid-ocean ridges? Mid-ocean ridges form the longest mountain range in the world, nearly all of which lies beneath the sea These ridges crisscross the world’s oceans like stitches on a baseball; together they measure nearly 65,000 kilometers (about 40,000 miles) in length Most of Earth’s volcanic activity occurs along mid-ocean ridges, which form along the seams between tectonic
- A new way to discover life in the ocean’s deepest, darkest places
If we want to learn more about the limits of life in our solar system, the ocean’s deep trenches and troughs are a great place to start Known as the hadal zone, a depth ranging from 6,000 meters (19,000 feet) and deeper, this ecosystem is home to animal life that is specially adapted to crushing pressure, inky blackness, and island-like
- Tsunamis in the Caribbean? It’s Possible. - Woods Hole Oceanographic . . .
The potential for earthquakes of magnitude 7 5 or greater in the trenches offshore Puerto Rico and Hispaniola pose additional risk While tsunamis are rare in the Caribbean, earthquakes are not A dozen earthquakes of magnitude 7 0 or greater have occurred near Puerto Rico, the Virgin Islands, and Hispaniola in the past 500 years
