I would suggest an alternative possibility.
Whales eat squids.
And ships are made of iron.
Humans are probably putting more iron in the sea than whales do.

Rusty ships are avoided, some of the iron is molecularly bonded to other metals and minerals, and rust from ships will sink immediately, and isn't really very bio available anyway. Rust flakes and particles are kinda difficult (and large) for crustaceans to rend and digest.
Irony whale poop has buoyancy, and the iron is bio available.
And squid eat...
The plural of "squid" is "squid", as the plural of "sheep" is "sheep".
Perhaps "squids" refers to multiple superconducting quantum interference devices.
