Hollywood director James Cameron returned safely from a dive that took him nearly seven miles to the bottom of the Mariana Trench. Encased in a narrow submersible of his own design, Cameron reached the bottom in an area of the trench known as Challenger Deep after a 2.5 hour descent. He spent three hours exploring the sea bottom using the well-outfitted submarine's cameras and sampling equipment to collect images, fauna, and other data from the silty seabed. The single-person capsule - built to withstand up to 1000 atmospheres of pressure - held up well under the eight tons(!) per square inch that six and a half miles of ocean water exerted upon it. As today goes on, I'm sure more information will come out about this remarkable feat. In the meantime, I'm really anxious to see what images he captured down there, and we'll all get that chance when the National Geographic Society - one of the expedition's sponsors - comes out with a planned future program about the dive.

Ever wanted to explore the ocean? Calm down, don't get out of your armchair, yet, Midwest. Thanks to Google Earth and researchers at Columbia University, you can take a sea cruise without leaving your pop or your Twitter account behind.

Why should you care about the oceans? Did you know that we have already consumed 90% of the population of large fish species in the ocean? That tiny plankton in the ocean provide 50-85% of the oxygen in the air we breathe? That ocean water is becoming more acidic from the same carbon dioxide emissions that warm our climate, thereby making it tough for some sea-life to survive?

Is a life without fish sticks really a life worth living?

Of course, you may not get all of that out of a spin on Google Earth, but exploring may well be the first step in your life-long romance with a crafty young cephalopod or a craggy-faced mid-ocean ridge. Plus, it's just darn cool.
