An example of metphor in science:

"But, then, when the phytoplankton die, and when the zoo plankton defecate and produce faecal pellets, these particles rain down through the ocean, so we call it marine snow because you can imagine it drifting slowly down through the depths to 4000 metres."

Prof. Carol Robinson

Prof. Carol Robinson (Professor of Marine Sciences at the University of East Anglia) was talking on an episode ('Plankton') of BBC's In Our Time

'Marine snow' might be consider a 'dead metaphor' within science as it has come to be used as a technical term.

Mixed metaphor: Should 'marine snow' 'snow down' rather than 'rain down'?
