The footage shows some impressive fields of stalked barnacles, an abundance of shrimp and some really cool sulfide chimneys and elemental sulfur flows.
Popular Science has just published its annual "Ten worst jobs in science" issue, and two of them are in marine science! How is this possible? Marine science is clearly the best job since, well, ever. Hmmmm, lets take a closer look.crushing depths, some of the snot also dissolves under the immense pressure of all the water above it, much like snow melting before it reaches the ground. In this way, the snot plays a very important part in taking nutrients produced at the surface, and dissolving them in the water at great depths. Maybe not the most attractive concept, but pretty important in the grand scheme of things. Like Tom Cruise says in The Firm: "Its not sexy, but its got teeth".
2. Whale slasher. OK, I have to concede that one. I've seen a few stranded whales being cut up on the beach (this is called a necropsy, not an autopsy, which is reserved for people only), and it pongs. I'm not talking sweat sock pong, or even doggy-breath-after-eating-goose-poo pong, but serious, invasive, gets-into-your-hair, throw-your-clothes-away stink. While the cause of death is always interesting, wading through week-old whale giblets that have been baking on the beach? Not so fresh...
Work reported in Nature today from a presentation at the annual AGU meeting shows easily the deepest underwater volcano ever filmed. The eruption was filmed from a remote submarine at 1200m depth - far more than the previous 500m depth record - and shows lava bursting out onto the sea floor. The discovery helps scientists understand how pillow basalts form and how sea floor materials are added to the oceanic crust.
Its hard to imagine how extreme that process is. We're talking hot enough to melt lead, at pressures that would turn a styrofoam cup into a thimble!
