Sukhoi Superjet avionics are calibrated to a maximum permitted sealevel pressure of 1052 hPa.

It was 1054 hPa in St. Petersburg today, so they got grounded.

Sailing north out of Nassau, Bahamas I noticed something different about the water.  It was a deep, dark almost black blue.  My kid asked me why it was so dark and I quipped that meant the water was probably in excess of 6,000 feet deep.

Literally just from stuff I picked up by hanging out with Navy types.

Turns out I was right.  

Just north of Nassau is a part of the ocean called "Tongue of the Ocean" that cuts through the plateau that makes up most of the shallow seas that give the Bahamas such beautiful water.  And yes - it was about 6,000 feet deep where we were.  Not far from there it can get as deep as 13,000 feet deep!

The Bahamas

FWIW - Nassau is pretty much in the middle of the map in the link above.

This is a Craspedacusta sowerbii, or a peach blossom jellyfish. It is a very unusual, freshwater jellyfish. Well, not actually a jellyfish, biologically speaking, but close enough. It is a very small creature, only 20-25 mm in diameter. Like all jellyfish, its body consists mostly of water. If placed in sea water, it would probably die, but the jellyfish's body would contain more water by volume, than the water it was swimming in. A bucket of water with a C. sowerbii in it would probably, on average, be so little polluted that it would pass most regulations for drinking water. It is only a small pinch of material more than water itself.

Now for the fun fact: a single C. sowerbii has more of a spine than every single politician in the Republican Party put together.
