UN: Ships Need To Shut Up So Whales And Dolphins Can Hear

The noises made by the gargantuan boats that move our stuff from one continent to another are ruining marine life. So, this week, new regulations have been issued by the International Maritime Organisation, the sea-faring agency of the United Nations, asking shipping companies to turn down the volume.


Shipping Containers Lost At Sea And The Search For Flight 370

Just how many large mysterious objects can there be floating at sea? That’s what many of us have wondered after the search for debris from Malaysia Airlines 370 turned up piece after piece of ocean trash. The search for flight 370 has focused our attention on empty patches of ocean and, in the process, shed light on the surreal world of lost shipping containers.


What Happens When You Throw Four Sharks Into A Giant School Of Fish

Four blacktip reef sharks swim amongst a school of bait fish off the coast of Argentina. The fish, naturally, do not seem happy to see said sharks. That is most certainly because the sharks are hungry…


Mysterious Underwater Rivers Criss-Cross The Bottom Of The Ocean

If you’ve ever made a trans-Atlantic call — or, heck, used the internet — then you might like to know a few things about the ocean floor. Mighty but enigmatic underwater rivers flow along the ocean bed. And it’s telecommunications companies, who have to lay thick cables for transoceanic phone and internet connections, with perhaps the most to worry about when it comes to mapping those rivers.


The UK Is Crowdsourcing Its Next Map Of The Ocean Floor

Believe it or not, we don’t know how deep large parts of the ocean off the British coast really are, and this is obviously not a good thing for the many sailors who cruise around those waters. A new project funded by the European Community is using technology to solve this problem — technology and lots of boats.


Tapping Into Wave Power With A Gigantic, Artificial 'Seafloor Carpet'

Scientists have known for decades that muddy coastal sediments absorb the power of waves as they roll toward beaches. The result is a free service courtesy of soft ocean bottoms that diminishes the sea’s energy before it reaches the communities living beyond them.


The Ultimate Whale Watching Vessel Isn't A Boat -- It's A Satellite

Whale watching: you’re out there on the water with salt spray in your face and wind in your hair, waiting for a gigantic sea mammal to surface and do something splashy. It seems like a touristy thing to do, but scientists actually track whale populations from that very same vantage point. Sea level’s cool and all, but wouldn’t it be awesome to monitor whales — FROM SPACE?? You’re damn right it would, and now it’s actually happening.


A Single Night Of Sex On This Luxury Hotel Submarine Costs $390,000

Well here’s a new option for the wealthy tourist who’s seen it all. No, it’s not a trip to space. It’s not a floating hotel room or even a wild safari. It’s a luxury submarine — an underwater palace built for a Bond villain that can be yours for the weekend. But it will cost you.


Our Rubbish Has Become A New Ocean Ecosystem Called 'The Plastisphere'

Sure, we all know pollution destroys ecosystems, but, for better or for worse, pollution can create ecosystems too. The billions of tiny pieces of plastic that are now floating in our oceans are exactly that: a novel ecosystem humans have unwittingly made by throwing away too much plastic. Microbes and insects that might have no business thriving in the middle of the ocean suddenly have found a new home amidst all that drifting plastic.
