I got to write 'acoustic Doppler current profiler' in a story today!

"Something bad isn't happening locally" isn't a very exciting news story, but sometimes fun stuff comes out of it. I have an article today about sequestraton and automatic stream gauges which notes that our local ones aren't threatened - ho-hum - but I did get to write about "acoustic Doppler current profiler".
That's how the gauges determine the flow of the river, as compared to just the depth. They bounce sound waves off debris floating in the water to determine the speed and volume of the water column at their location. Cool!
