>ELEPHANT SEAL DIVE >2400 METERS DEEP That one caught me off guard. I'm used to seeing stories (or "tales") of e.g. Sperm Whales accomplishing incredible dives like that. An elephant seal doesn't really seem to be tuned to that kind of performance dives.

I am not sure how deep they would be able to go with this technique but it might be helpful in shallow water. I mean, to equalise at 20m they would need to generate 2bar (~30psi) of pressure. That is quite a lot! For reference, humans can normally push about 0.1bar (1-2psi) by blowing.. and their sinuses would need to withstand that pressure at the surface, before they dive. Also, this has nothing to do with decompre…
>Also, this has nothing to do with decompression sickness (aka 'the bends'). That is to do with dissolved gases in the blood which turn into bubbles when the pressure is lowered. Dissolved gases dropping out of solution and forming bubbles is literally decompression sickness.

Yes, I'm pretty sure that is exactly what I wrote?

Dissolved bubbles in blood has everything to do with the bends.
and for clarity: 'forcing air into respiratory cavities in the skull' would not prevent the bends.
The content and presentation is fantastic. The page is using up 15-20% CPU and GPU when it is the active tab even when not scrolling. That seems unexpected and unfortunate. (I noticed because by the time I got to 3400 meters, my laptop's fans became audible.)
Same, dell xps13 is on fire. GPU 99%, cpu 30%. Unsure why.

This is because you are artificially pressurized by the air you're breathing when scuba diving that deep. If you held your breath and went that deep, you would definitely feel the pressure.
I think you can already feel that pressure when holding your breath and diving just 3m deep.

I read that some seals can also force air into respiratory cavities in their skull, which keeps them from suffering decompression sickness.

> Air is forced from the lungs during a dive and into the upper respiratory passages, where gases cannot easily be absorbed into the bloodstream. This helps protect the seal from the bends.
