Speak of Tethys,
Panthalassa, Iapetus,
Now on mountain tops,
or subducted, long ago.

Fly our rich North Atlantic,
or the vast, plastic, Pacific,
Indian, Arctic,
Here for a while…

Entirely white,
I’ve flown most of these,
punctuated only by the black point
of my mind’s eye.

but of all the Oceans we know
The best cannot be seen:
Waters kept from the Sun, beneath ice, a globe entire;
Europa, Deep Blue Moon.
