As carbon dioxide accumulates in the atmosphere, the Earth will get hotter. But exactly how much warming will result from a certain increase in CO2 is under study. The relationship between CO2 and warming, known as climate ...

Volunteer clean-ups have resulted in almost nine metric tons of marine litter being cleared from beaches across the Seychelles, in what researchers have described as a powerful demonstration of the potential of citizen science.

Tropical marine species venturing into new areas as the climate changes could fall victim to another effect of the phenomenon—as bursts of cold water from the deep sea suddenly kill them.

Global climate models, such as the Energy Exascale Earth System Model developed by the U.S. Department of Energy, rely on many underlying equations that simulate Earth's natural processes. These include the water cycle, carbon ...

A new study published in Nature Communications has revealed that the interplay between meandering ocean currents and the ocean floor induces upwelling velocity, transporting warm water to shallower depths. This mechanism ...

A team of marine biologists and oceanographers at the Woods Hole Oceanographic Institution in Falmouth, Massachusetts, has found that creating soundscapes for coral larvae encourages them to settle on desired coral reefs.
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.
