The tide, and the water around it.
NOAA's tide for our creek under the real sky, the Weather Service's flood, surf and marine forecasts, and the buoys off Charleston, in one place. Official numbers come first and say whose they are; where the arithmetic is ours, it says so.
Answers come from the node, live NOAA and weather-service data, our research on 59 animals, and a plain-English glossary. It matches keywords; it isn't AI, so when it doesn't know, it says so.
