The Indian Ocean is the world's warmest ocean, holding the record for the highest average sea surface temperatures, generally ranging from 22°C to 28°C (72°F to 82°F) due to its tropical location and enclosed geography, which traps heat and limits cold polar water inflow. Its warmth significantly influences global climate, affecting monsoons and supporting rich marine life, notes Guinness World Records and Wikipedia.
The Indian Ocean has the warmest surface temperature of all the world¹s oceans, as most of it is found in the tropics.
The Red Sea is the hottest, and saltiest sea on earth, but vibrant, healthy coral reefs thrive here. Researchers want to understand what makes these corals so resilient, as it could unlock how to saving threatened reefs around the world.
The Pacific claims the crown for size, depth, biodiversity, and consistent surf. While the Atlantic holds its own charm, the Pacific Ocean stands out for surfers chasing steady waves and vibrant seas.
It surrounds the Arctic and the North Pole. The Arctic is the coldest of all the oceans. Most of the Arctic Ocean is covered with ice all year.
The South Pacific is the least polluted of the world's oceans. There are about 150 million metric tons of plastic in the oceans and a further 8 million metric tons are added to the oceans annually.
As the world's largest ocean, the Pacific Ocean harbors some of the most dangerous waters. Typhoons, strong currents, and rocky shores pose significant threats to unprepared ships navigating this expansive region.
Holding more than half of the Earth's open water supply, the Pacific Ocean was named by explorer Ferdinand Magellan in 1520, who called this body of water “pacific,” due to the calmness of the water at the time ('pacific' means peaceful).
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean, or, depending on the definition, to Antarctica in the south, and is bounded by the continents of Asia and Australia in the west and the Americas in the east.
The most polluted ocean is the Pacific with 2 trillion plastic pieces and one third of the plastic found in this ocean circulates in the North Pacific Gyre. An ocean gyre is a large system of circular ocean currents formed by global wind patterns and forces of the Earth's rotation.
“Antarctic bottom water” is the coldest, saltiest water on the planet. These waters play a crucial role in the ocean's ability to act as a buffer against climate change by absorbing excess heat and human-caused carbon pollution.
Most adults will suffer third-degree burns if exposed to 150 degree water for two seconds. Burns will also occur with a six-second exposure to 140 degree water or with a thirty second exposure to 130 degree water. Even if the temperature is 120 degrees, a five minute exposure could result in third-degree burns.
Ninety-five percent of the ocean remains unexplored not because it is empty… But because it is too powerful, too deep, too mysterious for us to rush into carelessly. The ocean is not hiding from us.
More than 70% of our planet is ocean – and 90% of that ocean is deep sea.
The immense size of the Pacific Ocean
Ships prefer longer, safer routes rather than crossing the North Pacific directly between Russia and the US. This is because this region faces winds that reach 160 km/h, frequent storms and waves that can reach 30 meters in height.
Psalm 104:25-26 – “There is the sea, vast and spacious, teeming with creatures beyond number-living things both large and small. There the ships go to and fro, and Leviathan, which you formed to frolic there.” Psalm 95:5 – “The sea is his, for he made it, and his hands formed the dry land.”
Eight scary sea creatures that really exist
Violent winds from a hurricane or tornado, lightning from thunderstorms, and rising floodwaters come to mind. But the weather event that actually produces the greatest number of fatalities is heat.
Summary: 2025 is a transformative year for ocean governance, marked by three landmark events: the UN BBNJ Convention entering into force, new WTO fisheries subsidies regulations taking effect, and the adoption of a historic political declaration at the 2025 UN Ocean Conference.
