Ocean

When it's determined that a boater is officially missing at sea, it helps very much to know when and where their vessel sank. According to new research, barnacles growing on flotsam could provide that information.

When we hear about microplastic particles polluting the ocean, the usual suspected sources are degraded plastic goods and synthetic textile fibers. A new study, however, suggests that much of the blame lies with hull coatings on ships.

If you were a marine animal that just sat and waited for food to drift by, you might not choose to live in a place where little life is believed to exist. Nonetheless, such critters have recently been found deep beneath an Antarctic ice shelf.

Home to oceans of liquid methane, Saturn’s moon Titan is one of the most fascinating bodies in the solar system. Now scientists have used radar to probe the depth of its largest sea, Kraken Mare, and estimated it to be at least 300 m deep.

San Francisco-based aquatic drone-maker Saildrone has returned with a bigger and better version of its unmanned vehicle designed to explore the seas, the newly introduced 72-ft (22-m) Saildrone Surveyor.

A new study as shone a light on the role deep-sea trenches can play in the movement of plastic pollution, revealing how they can act as traps, accumulating large amounts of microplastic particles and holding them there.

It is said that we know more about the surface of Mars than the seafloor. A new technique could help us fill in the blanks by using deep-dwelling rays to survey the seabed for us, and possibly even power the required hardware themselves.

Although AUVs (autonomous underwater vehicles) excel at gathering marine data without human intervention, they're still limited by battery life. Texas startup Terradepth has set out to address that problem, with a novel tag-team system.

While it's important for biologists to know which organisms have colonized the seabed in a given area, excavation is both labor-intensive and ecologically unsound. That's where the Autonomous Reef Monitoring Structures (ARMS) are made to come in.

A team of scientists from three notable oceanographic institutions has discovered the largest-ever aggregations of fish to be seen in the abyssal deep-sea region of between 9,800 and 19,600 feet beneath the ocean surface.

With the world continuing to warm and sea levels continuing to rise, NASA and the ESA are eyeing the next decade of climate change and its consequences, launching a new satellite to observe the ocean in greater detail from orbit.

When natural ocean shoreline is replaced by an artificial seawall, a lot of precious intertidal habitat is lost. A new study, however, indicates that by covering those walls with specially designed tiles, a substitute habitat can be created.
