Incredible diversity exists in the ocean, from microscopic organisms to the largest animals on Earth.
The ocean covers more than 70% of Earth’s surface and contains 97% of the planet’s water. This vast, critical reservoir supports a abundance of life and helps regulate Earth’s climate.
The ocean water column is made up of five zones: the sunlight (epipelagic), twilight (mesopelagic), midnight (bathypelagic), abyssal (abyssopelagic) and hadal zones (trenches).
Explore how the ocean shapes life on Earth. It sustains us, surprises us, and holds mysteries we're only beginning to understand. Dive into key topics here.
The ocean is a vast and critical reservoir that supports a diversity of life, helps regulate climate, provides a large amount of the planet’s oxygen, and stores an abundance of carbon dioxide. NASA satellite, airborne, and in-situ missions and projects are constantly collecting data about the global ocean.
Oceans Got pesky, invasive corals? Blast ‘em away with air guns Compressed air bids bye-bye to invasive sun corals in Brazil. The blasts obliterated soft tissue and fragments couldn't regenerate.
Understanding how the ocean works is foundational to understanding life on this planet and to the discipline of oceanography. Get to know the big systems of the ocean: its cycles, circulation, zones, and connection to the atmosphere. Learn about ocean chemistry, life and landscapes on the seafloor, plate movements, shorelines, and icy regions.
