Há 5 dias · The average depth of the oceans is about 4 km. More precisely the average depth is 3,688 meters (12,100 ft). Nearly half of the world's marine waters are over 3,000 meters (9,800 ft) deep. "Deep ocean," which is anything below 200 meters (660 ft), covers about 66% of Earth's surface.
Há 3 dias · The new MyOcean viewer powered by the Copernicus Marine service is an opportunity for everyone to be able to display maps of the ocean in 4 dimensions (longitude, latitude, depth, and across time).
Há 1 dia · The Pacific Ocean's mean depth is 4,000 meters (13,000 feet). Challenger Deep in the Mariana Trench , located in the northwestern Pacific, is the deepest known point in the world, reaching a depth of 10,928 meters (35,853 feet). [4]
Há 2 dias · The mean depth of the Pacific (excluding adjacent seas) is 14,040 feet (4,280 metres), and its greatest known depth is 36,201 feet (11,034 metres)—in the Mariana Trench—also the greatest depth found in any ocean.
Há 12 horas · Specifically, deep oceans (>200 m below sea level) are among the most underestimated habitats, partly because of their remoteness and high cost of field sampling. In contrast to the upper oceans (<200 m depth), deep oceans are characterized by a few specific conditions such as a lack of light, low temperature and high water pressure.
Há 2 dias · The Atlantic Ocean has an average depth (with its seas) of 11,962 feet (3,646 meters) and a maximum depth of 27,493 feet (8,380 meters) in the Puerto Rico Trench, north of the island of Puerto Rico. What is a major feature of the seafloor of the Atlantic Ocean?
Há 5 dias · The largest single hadal features in the Southwest Pacific Ocean are the Kermadec and Tonga trenches at 145,103 and 111,951 km 2 respectively. In the Indian Ocean, the Java Trench represents the only subduction trench, and has an area of 69,095 km 2, albeit partitioned by a bathymetric high into two hadal components.
