Raw multibeam bathymetry data were collected aboard RV SONNE during cruise SO314 using a Kongsberg EM 122 multibeam echosounder. The expedition took place during 2025-08-13 – 2025-10-15 from Papeete (French Polynesia) to Antofagasta (Chile) in the South Pacific. There are detailed reconstructions of past sea-level changes but there are no corresponding high-resolution records of how geological processes on the ocean floor have evolved over time. The generation of such records along fast spreading Mid Ocean Ridge of the Southeast Pacific Rise (SEPR) was the goal of cruise SO314. Data were recorded within international waters. Sound velocity profiles (SVP) were applied on the data for calibration. Please see environmental data and the cruise report for details. The data are unprocessed and can therefore contain incorrect depth measurements (artifacts) if not further processed. Note that refraction errors may occur when no proper SVP is applied. Data acquisition was done by GEOMAR Helmholtz Centre for Ocean Research Kiel, provision of the data is supported by the DAM Project Underway Research Data and published according to the FAIR principles. ** For all details see the full metadata description at "https://doi.pangaea.de/10.1594/PANGAEA.992882"! ** These data should not be used for navigational purposes.
