One Global Ocean, Five Distinct Regions
Earth’s oceans cover over 71% of the surface and hold 97% of its
water, making our planet truly unique.
The five officially recognized oceans are the Pacific, Atlantic,
Indian, Arctic, and Southern.
Despite their individual names, they are all interconnected,
forming one vast, dynamic global ocean system that regulates
climate and supports immense biodiversity.

support an incredibly rich marine biodiversity, from vast fisheries to
unique ecosystems.

The Arctic and Southern Oceans: Extremes of the Planet
The Arctic Ocean is the smallest and shallowest, largely covered by sea ice year-round. It's a critical habitat for polar ecosystems,
including polar bears, seals, and unique fish species.
The Southern Ocean is a newly recognized fifth ocean, encircling Antarctica. Its cold, nutrient-rich waters are key to global
climate regulation and support massive populations of krill, whales, and penguins.

Protecting Our Oceans: The Future of Earth’s Lifeblood
Our oceans are fundamental to life on Earth. They produce over half the oxygen we breathe and directly sustain billions of lives through food,
livelihoods, and climate regulation.

Understanding and preserving our oceans is
vital for future generations.
Rising temperatures lead to habitat loss and
species migration.
Addressing rising pollution, ocean acidification, and warming waters is essential to safeguard the health of our planet's most vital resource.
