Abstract:
In May of 2019 the US American research vessel Marcus G. Langseth shot seismic profile p01 across the Emperor Seamounts in the northwest Pacific Ocean. Shots were recorded on 27 ocean-bottom-seismometers (OBS) of the US American Pool and GEOMAR Helmholtz Centre for Ocean Research Kiel. Seismic data in SEGY format of the GEOMAR OBS are here available from PANGAEA Datacenter. Please note that the data have a time offset of 1 sec and a reduction velocity of 8 km/s. The SEGY data from the US American OBS are available at the Incorporated Research Institution for Seismology (IRIS) under the network code ZU. The seismic survey was funded by the US American National Science Foundation (Awards OCE17-37243, OCE17-37245).
