SIEGEL: A very well-traveled little bit of plastic there. How do you follow them around all the seas as they make their way?

Dr. EBBESMEYER: Well, I have a worldwide network of beachcombers who report in, and every quarter I summarize what they say, so there are eyes and ears around the world looking for things that fall out of cargo ships.

SIEGEL: Is this called flotsamology?

Dr. EBBESMEYER: Well, flotsametrics.

This term is still linked to its coiner, the oceanographer Dr. Curt Ebbesmeyer, meaning that mentions of the word still reference either Dr. Ebbesmeyer or his book, Flotsametrics and the Floating World. I usually don't cover a term until it gets "unlinked" from its coiner and is freely roaming the culture, but flotsametrics is just too good a word to pass by. A tip of the Word Spy fedora to reader Sharon Ede for passing this one along.
