Scientists discover the biggest seaweed bloom in the world

Scientists led by the USF College of Marine Science used NASA satellite observations to discover the largest bloom of macroalgae in the world called the Great Atlantic Sargassum Belt (GASB), as reported in Science.

New model suggests lost continents for early Earth

A new radioactivity model of Earth's ancient rocks calls into question current models for the formation of Earth's continental crust, suggesting continents may have risen out of the sea much earlier than previously thought ...

In search of an undersea kelp forest's missing nitrogen

Plants need nutrients to grow. So scientists were surprised to learn that giant kelp maintains its impressive growth rates year-round, even in summer and early fall when ocean currents along the California coast stop delivering ...

Following the ocean's flow

The dramatic sight of Atlantic waves crashing onto UK shores from the vast, surging ocean illustrates perfectly the joke behind its nickname of 'The Pond'.

Mapping the ocean's unseen heroes, one microbe at a time

The picture of how climate change is impacting our ocean is often told via its larger inhabitants: scrawny polar bears, bleached coral, dwindling catch in fishing nets. But just as importantly, microscopic marine organisms ...

New study finds microplastic throughout Monterey Bay

Many people have heard of the "Great Pacific Garbage Patch," a vast area of ocean between California and Hawaii where ocean currents concentrate plastic pollution. However, it turns out there may also be a lot of plastic ...

How deep-ocean vents fuel massive phytoplankton blooms

Researchers at Stanford University say they have found an aquatic highway that lets nutrients from Earth's belly sweep up to surface waters off the coast of Antarctica and stimulate explosive growth of microscopic ocean algae.

Ocean current

An ocean current is a continuous, directed movement of ocean water generated by the forces acting upon the water, such as the Earth's rotation, wind, temperature, salinity differences and tides caused by the gravitational pull of the Moon and the Sun. Depth contours, shoreline configurations and interaction with other currents influence a current's direction and strength.

Ocean currents can flow for thousands of kilometers, and together they create the great flow of the global conveyor belt which plays a dominant part in determining the climate of many of the Earth’s regions. Perhaps the most striking example is the Gulf Stream, which makes northwest Europe much more temperate than any other region at the same latitude. Another example is the Hawaiian Islands, where the climate is cooler (sub-tropical) than the tropical latitudes in which they are located, because of the effect of the California Current.
