Science Friday
A vast whale graveyard + Zombie sea cucumbers

Your chances of seeing a whale in the ocean is not equal everywhere.

Science Friday
A vast whale graveyard + Zombie sea cucumbers

Whales seem to prefer certain corridors.

Science Friday
A vast whale graveyard + Zombie sea cucumbers

Yeah.

Science Friday
A vast whale graveyard + Zombie sea cucumbers

And that's a result of decades and decades of work of tracking whales, where they go to feed, where they go to eat, to mate, all through the course of...

Science Friday

maybe a migration cycle.

Science Friday

And you kind of expect to find the remains of those superhighways on the seafloor underneath.

Science Friday
A vast whale graveyard + Zombie sea cucumbers

So there should be places around the world that you expect to find the remains of whales.

Science Friday
A vast whale graveyard + Zombie sea cucumbers

And I think this is probably one of them.

Science Friday
A vast whale graveyard + Zombie sea cucumbers

The other thing that's really spectacular about this finding is just the extent.

Science Friday
A vast whale graveyard + Zombie sea cucumbers

I mean, we're talking about an area that

Science Friday

in one linear distance might measure the same distance from New York to Chicago.

Science Friday
A vast whale graveyard + Zombie sea cucumbers

So imagine driving from New York to Chicago and there are just whale bones littered all across the highway.

Science Friday
A vast whale graveyard + Zombie sea cucumbers

That's a bit mind-bending, I think.

Science Friday
A vast whale graveyard + Zombie sea cucumbers

Yeah.

Science Friday
A vast whale graveyard + Zombie sea cucumbers

So they found two different categories of whale sites.

Science Friday
A vast whale graveyard + Zombie sea cucumbers

They found the remains of fossil whales, and then they also found a whale fall that is kind of like a whole ecosystem that colonizes on the carcass of the remains from a living whale.

Science Friday
A vast whale graveyard + Zombie sea cucumbers

And from that group, they found baleen whales and a lot of other beaked whales.

Science Friday
A vast whale graveyard + Zombie sea cucumbers

Most of the fossil sites seem to just be beaked whales.

Science Friday
A vast whale graveyard + Zombie sea cucumbers

I think that the experience the researchers must have had was just coming across whale skeleton after whale skeleton as they cruised in their submersible along the seafloor.

Science Friday

And that's why the researchers said, you know, this is a megacite.
