USNS Bowditch was placed out of service in 1988 and transferred to the Maritime Administration (MARAD) National Defense Reserve Fleet in Beaumont, TX.  She was struck from the Naval Register and disposed of by MARAD exchange on Mar 4, 1988.

This article from the trade journal Sea Technology describes events in Rio de Janeiro Harbor which ended Bowditch's distinguished thirty-year career in oceanographic survey.

Naval Oceanographic Office Bulletin, Apr/May 2003

An article by HMC Dennis Hunt, published in the Naval Oceanographic Office Bulletin, Apr/May 2003. Chief Hunt served on Bowditch in 1986-1987 during what was probably her last deployment.  This is a sad ending. I'm glad to see that the brass plate ended up at NAVOCEANO.  I wonder what happened to her bell?
