The definition of global mean surface pH refers to the top layer of the water in the ocean, up to around 20 or 100 m depth. In comparison, the average depth of the ocean is about 4 km. The pH value at greater depths (more than 100 m) has not yet been affected by ocean acidification in the same way.
At 36,070 feet (10,994 meters) below sea level, Challenger Deep in the Pacific Ocean’s Mariana Trench is the ocean’s deepest known point. (The graphic below contrasts relative ocean depth with the sizes of various locations, structures, and feats.) Chatbot answers are created from Britannica articles using AI.
Oct 19, 2023 · However, if depth were measured from the ocean floor, the Challenger Deep in the Pacific Ocean would be the lowest place on Earth. It measures 11,034 meters (36,200 feet) below sea level. Conversely, the top of Mount Everest in the Himalaya is the point with the highest elevation on Earth, at 8,848 meters (29,028 feet) above sea level.
Nov 11, 2024 · So horizontal dimensions of ocean basins are 1,000 times greater than the vertical dimension. A scale model of the Pacific, the size of an 8.5 × 11 in sheet of paper, would have dimensions similar to the paper: a width of 10,000 km scales to 10 in., and a depth of 3 km scales to 0.003 in., the typical thickness of a piece of paper.
The average depth of the ocean is about 3,682 meters (12,080 feet). The deepest part of the ocean is called the Challenger Deep and is located beneath the western Pacific Ocean in the southern end of the Mariana Trench, which runs several hundred kilometers southwest of the U.S. territorial island of Guam.
Oct 30, 2015 · The deepest point of the Earth’s oceans lies at 36,069.55 feet ± 131.234 feet (10,994 meters ± 40 meters). It is the maximum-known depth of the Mariana Trench (the Challenger Deep). Understanding these depths is crucial for mapping the ocean floor, monitoring climate change, and developing sustainable fishing practices.

Feb 27, 2024 · The depth of the ocean on planet Earth is not uniform. It varies a great deal on the basis of geography. DOERS/Shutterstock. To know the ocean is to know some mind-boggling numbers. About 71 percent of Earth's surface is covered by seawater. All that liquid takes up more than 332,519,000 cubic miles — or 1,386,000,000 cubic kilometers — of ...
