This page provides data from the Deep-ocean Assessment and Reporting of Tsunami (DART®) buoys and processed NOAA/NOS/CO-OPS coastal tide-gauge stations. Files contain raw observations, fitted tidal components, and residual tide values. The DART® data are the real-time water level data (in meters) as recorded by the Bottom Pressure Recorder (BPR) in extended-reporting mode containing measurement types of 15 minutes, 1 minute, and 15 seconds. Real-time data were extracted from the National Data Buoy Center.
For DART 4G 46403 and 46410 data, records may be provided upon request. On the right of the Tsunami Travel Time map below there are links to individual data files under column Data. The columns in those files are as follows: Time is in Julian days from the beginning of the year, Year, Month, Day, Hours, Minutes, Seconds, Raw Observations, Fitted tidal component, and computed residuals in meters water column.
Details on the data processing methods.
