THERE IS WATER AT THE BOTTOM OF THE OCEAN

CARRY THE WATER

REMOVE THE WATER

Actually! This was a very clever setup by a team of divers in the Arctic, I believe. The person is upside down, their buoyancy belt* calibrated just so that they are slightly lighter** than water, and able to walk upside down on the ice. In the first segment, when his mask vents***, watch the bubbles flow DOWNWARD, which is really the up that we know. Science is really fricking cool!

** Positively Buoyant
***Regulator

Eitherway, cool.

Can’t tell if that’s a bucket of air or really warm water though, as warm water has a different visual appearance to the cold Arctic waters.

the world wildlife fund estimates that each year 4.4 million sharks are unintentionally caught as bycatch from unregulated commercial tuna fisheries using long lines and drift nets. a shark caught in a net will suffocate to death. shark numbers have declined by as much as 80 per cent worldwide, with a third of all species now threatened by extinction (pew charitable trusts). photos by (click pic) fiona ayerst, adam baughterry maas and brian skerry
