Langmuir circulation inhibits near-surface water turbulence

Langmuir circulation inhibits near-surface water turbulence | Remote Sensing of ocean & coastal waters | Scoop.it
In the surface ocean, breaking waves are a major source of air bubbles and turbulent kinetic energy. During the presence of a consistent surface wind, these wave-generated bubbles, along with other surface material like seaweed or foam, can be drawn into long rows along the surface.

Tropical cyclone waves detected with infrasound sensor array

Tropical cyclone waves detected with infrasound sensor array | Remote Sensing of ocean & coastal waters | Scoop.it
The strong winds of a tropical cyclone whip up the sea surface, driving ocean waves a dozen meters (about 40 feet) high. When one such ocean wave runs into another wave that has an equal period but is traveling in the opposite direction, the interaction produces low-frequency sound waves that can be ...

Satellites Spy on Fish Farms | The Scientist | Remote Sensing of ocean & coastal waters | Scoop.it

Scientists use Google Earth to fact check official reports of fish farming in the Mediterranean.

The fishing industry is notorious for underreporting the number of organisms that are being fished out of the world’s oceans every year. To this end, publicly available satellite imagery may prove a valuable tool for monitoring fishing practices worldwide as well double checking official data released by countries and organizations.
