The data set provides unprocessed and processed seismic reflection data collected during Expedition PS115-2 onboard RV Polarstern across the southeastern Lomonosov Ridge and in the Amundsen Basin in 2018. Detailed data acquisition parameters for the profile are documented in the expedition report (Stein, 2019). Metadata, recording parameters, and the seismic data processing sequence are documented in the EBCDIC-Headers enclosed in the seg-y files. Navigation information is included in the seg-y headers, and in the CDP-SHOT-latitude-longitude file (see data product). A ReadMe file additionally lists the metadata and recording parameters for the seismic profile. The data set is grouped into three categories: 1. Raw data comprise (a) demultiplexed seismic data in segy format, (b) navigational data in a P1/90 UKOOA- file. 2. Primary data consist of (a) CDP-sorted data in segy format 3. The data product is provided as (a) stacked version of the seismic profile in segy format and (b) a list with CDP and SHOT numbers as well as geographical coordinates.
