Oceans | Deep Sea, Marine Life, and Ocean Science

The ocean is Earth's largest habitat, covering 71 percent of the planet's surface and driving global climate, weather, and nutrient cycles. Despite its size, less than 20 percent of the seafloor has been mapped at high resolution, and new species are discovered on nearly every deep-sea expedition.

Marine Ecosystems and Biodiversity

Coral reefs, kelp forests, seagrass meadows, and deep-sea hydrothermal vents each host distinct communities of organisms adapted to extreme conditions. The health of these ecosystems is directly tied to ocean temperature, acidity, and nutrient availability. Our coverage tracks the latest research on marine heatwaves, coral bleaching, and species migration patterns as the ocean warms.

Deep-Sea Exploration

Advances in remotely operated vehicles (ROVs), autonomous underwater vehicles (AUVs), and satellite oceanography are opening new frontiers in deep-sea research. From hydrothermal vent ecosystems that operate without sunlight to abyssal plains that store centuries of carbon, the deep ocean remains one of the least understood environments on Earth.

Ocean and Climate

The ocean absorbs roughly 30 percent of anthropogenic carbon dioxide and over 90 percent of excess heat from greenhouse gas warming. This makes it the planet's most important climate buffer, but the cost is rising ocean temperatures, acidification, and deoxygenation. Understanding these physical processes is essential for predicting future climate scenarios.
