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

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.

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.

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.

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.
