Today's word

There haven't been many new words for me of late in the words of the day. Fortunately there's the occasional new one in the dictionary devil puzzle:

bathymetery /bə-ˈthi-mə-trē/ - the measurement of water depth at various places in a body of water; also :  the information derived from such measurements

I saw this at work on our recent trip to Tennessee for the eclipse, as our host was able to let us know the current depth of the water wherever we were on the Clinch river.
