Information from ocean exploration can help us understand how we are affecting and being affected by changes in Earth's environment, including changes in weather and climate. Insights from ocean exploration can help us better understand and respond to
earthquakes, tsunamis, and other hazards
.
Why is the deep sea important?
By
storing a large part of the CO2 produced by human activities
and by absorbing the heat accumulated by greenhouse effect, the Deep Sea slows down the warming of surface waters and land. Thanks to this immense mass of water, climate change is still “bearable” for most species on Earth.
What does the deep sea do for us?
The deep ocean is
critical for the maintenance of the Earth's climate
. … Warmer water is not able to hold as much oxygen as cold water; so as the ocean warms, it also loses oxygen. Sequestering carbon in the deep sea is being explored to help reduce carbon in the atmosphere.
Why is it important to learn about the ocean?
The air we breathe
: The ocean produces over half of the world's oxygen and absorbs 50 times more carbon dioxide than our atmosphere. Climate regulation: Covering 70 percent of the Earth's surface, the ocean transports heat from the equator to the poles, regulating our climate and weather patterns.
How does the deep sea impact humans?
The activities that may be of highest impact are
deepwater fishing together with climate change and ocean acidification
, as well as the accumulation of marine litter and chemical pollutants.
How deep in the ocean can fishes live?
Ocean-going fish can't live any deeper
than 8200 meters
, according to a new study. All fish have their limits—you'll never find sharks below 4 kilometers, for example—but why there aren't any fish at all below 8 kilometers remains a mystery.
What is deep inside the ocean?
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. Challenger Deep is approximately 36,200 feet deep.

At what depth is the ocean dark?
It is sometimes referred to as the midnight zone or the dark zone. This zone extends from
1,000 meters (3,281 feet) down to 4,000 meters (13,124 feet)
. Here the only visible light is that produced by the creatures themselves. The water pressure at this depth is immense, reaching 5,850 pounds per square inch.
What are the names of 3 major ocean basins?
The Pacific, Atlantic, and Indian
are the most commonly known. The Southern Ocean is the ‘newest' named ocean. It is recognized by the U.S. Board on Geographic Names as the body of water extending from the coast of Antarctica to the line of latitude at 60 degrees South.

Why is ocean water salty?
Salt in the sea, or ocean salinity, is
mainly caused by rain washing mineral ions from the land into water
. Carbon dioxide in the air dissolves into rainwater, making it slightly acidic. … Sodium and chloride, the main constituents of the type of salt used in cooking, make up over 90% of all the ions found in seawater.
Does the ocean produce oxygen?
The ocean produces
oxygen through the plants
(phytoplankton, kelp, and algal plankton) that live in it. These plants produce oxygen as a byproduct of photosynthesis, a process which converts carbon dioxide and sunlight into sugars the organism can use for energy.

How are humans helping the ocean?
Consider joining an organization that works to protect ocean habitats or volunteering at
local beach cleanups
. Support local restaurants, grocery stores, and businesses in your community that offer sustainable seafood and alternatives to single-use plastics.
