The dataset contains the real-time GNSS position solutions from ships in the Ship-based GNSS Tsunami Detection Pilot Network. Each file contains the full rate ascii position data for one calendar year per ship with one line per record and the following columns:

    YYYY MM DD HH MN SS LAT LON ELEV SIGMAY SIGMAX SIGMAZ
    

    Date and time are in UTC. LAT LON are in degrees, with ELEV being the antenna reference point height in meters above the WGS84 ellipsoid. SIGMAX|Y|Z are the formal errors returned by the RTX Positioning service onboard each ship's GNSS receiver (Units are meters).

    Files are named by ship and year. (Note that the Maersk Aotea started the project named Maersk Svend, and its name was changed during the project. We have gathered all the data under its Aotea name.

    • The R/Vs Kamimikai and Kilo Moana are research vessels from the University of Hawaii
    • The R/V Ron Brown is a NOAA research vessel.
    • M/V Mahimahi and Manoa are Matson Inc container ships.
    • Maersk ships are all the same model of container ship.
