Ocean

A barnacle-encrusted camera found by Gizmag writer Ben Coxworth

If you place pretty much any type of solid material in the ocean, barnacles will firmly attach themselves to it. If you were to try applying a glue to any of those materials while they were underwater, however, it likely wouldn't stick. So, what do barnacles know that we don't? Scientists have recently discovered the answer, and it could lead to advances in human technologies.  Read More

The Clever Buoy is designed to detect sharks and send alerts to lifeguards

In many parts of the world, shark attacks are a very real possibility for anyone entering the ocean. While suspended nets do help keep the toothsome fish separated from swimmers, they're far from from 100 percent reliable, plus sharks (along with other marine animals) regularly get caught in them and perish – as sharks are one of the ocean's apex predators, removing them from the ecosystem could have disastrous consequences. The Clever Buoy, however, may prove to be an effective method of keeping humans and sharks apart, with no harm coming to either.  Read More

MIT proposes building floating nuclear power plants located 5 to 7 miles into the ocean, e...

The most frightening part of a tsunami hitting a nuclear power plant is what comes after – radioactive leaks that contaminate the water around the plant are exceedingly difficult to contain. The clean up of the radioactive water around the Fukushima Daiichi nuclear plant in Japan, which was struck by a tsunami in 2011, is expected to take decades. MIT researchers have come up with an alternative; they propose building floating nuclear plants, far enough offshore to simply ride out a tsunami and emerge unscathed.  Read More

With the use of its Cassini spacecraft and the Deep Space Orbiting Network, NASA has potentially discovered evidence for the presence of an ocean of liquid water locked away beneath the thick, icy crust of Saturn's moon, Enceladus.  Read More

A six-gill shark sports one of the camera packs

Perhaps you've seen footage from National Geographic's "Crittercam," an underwater video camera that has been attached to animals such as sharks and whales. Well, scientists from the University of Hawaiʻi at Mānoa and the University of Tokyo have gone one better. Not only have they been putting cameras on sharks to see what they get up to, but they've also been slipping them ingestible sensors, to monitor their dietary habits. The data that they've gathered could help protect shark populations, and the overall health of the ocean.  Read More

Using X-rays and other forms of radiation has been a standard tool for testing pipelines for decades, but until now it's been largely confined to factories and land-based pipelines instead of the deep seabed. That’s changing as GE adapts its medical X-ray systems to work in the crushing pressures of the deep oceans, as part of a remote-controlled submersible rig for examining pipelines in place.  Read More

A rubber mat forms the 'carpet,' and sits atop a grid of hydraulic actuators, cylinders an...

Many organizations around the world are looking at ways to harness the power of waves as a renewable energy source, but none are covering quite the same ground as a team of engineers from the University of California (UC), Berkeley. The seafloor carpet, a system inspired by the wave absorbing abilities of a muddy seabed, has taken exploring the potential of wave power to some intriguing new depths.  Read More

The Snorkelboard – it's like a glass-bottom boat, except a tad smaller

Just about everyone who's comfortable with swimming in the ocean is at least somewhat interested in seeing what's in the water below them. Not everyone, however, is so keen on actually sticking their head below the surface and breathing through a snorkel. If you're one of those people, you might like the Snorkelboard.  Read More

Heat stored in the Pacific Ocean could be a ticking climate time bomb (Photo: Shutterstock...

Despite an overwhelming consensus among climate scientists that warming trends over the past century are most likely the result of human activities, some claim that a plateau in global surface air temperatures since 2001 is evidence to the contrary. However, a new study suggests the recent stabilization of air temperatures is a result of abnormally strong east to west trade winds, causing warmth to be stored temporarily beneath the western Pacific ocean.  Read More

Starboard profile of Alvin that is returning to service after a three-year overhaul

The National Science Foundation (NSF) announced on Friday that the Alvin deep-sea submersible is returning to service. The DC3 of the oceanographic world was launched fifty years ago in 1964 and is ready to begin its second half-century of service after a three-year overhaul involving significant redesigns and upgrades.  Read More
