Distress signal at sea (3)

I believe the answer is:

sos

(Other definitions for sos that I've seen before include "Coded distress signal" , "request for aid" , "urgent appeal" , "Morse Code for help" , "plea" .)

I've seen this clue in the Newsday, the USA Today, the L.A. Times Daily and the Newsday.com.
