The world's oceans cover more than 70% of Earth's surface. They're filled with currents, some much stronger than the fastest flowing large rivers. These currents can be harnessed as clean, marine ...

New research reveals how ocean warming triggered the large-scale retreat of the Northeast Greenland Ice Stream (NEGIS)—offering vital clues for understanding its modern-day vulnerability. NEGIS is the ...

While scientists have long studied currents of large eddies, the smaller ones -- called submesoscale eddies -- are notoriously difficult to detect. These currents, which range from several kilometers ...

This map of kinetic energy flux shows the global average power density calculated using drifter data in watts per square meter. As global electricity demand grows, traditional energy sources are under ...

The Atlantic meridional overturning circulation (AMOC) is a major oceanic current determining global climate that is showing signs of weakening. It transports warmer waters northwards in the Atlantic ...

How can open ocean currents generate energy? Ocean currents contain kinetic energy that can be converted to electrical power using turbines. This is similar to offshore wind farms, or wind turbines ...
