Abstract:
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, Navigation files in UKOOA-format (see raw data), and in the CDP-SHOT-latitude-longitude file (see primary data). 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 and (b) a list with CDP and SHOT numbers as well as geographical coordinates. 3. The data product is provided as (a) brute-stack version of the seismic profile in segy format. Please note that the low-frequency reflector that parallels the sea floor at depths of about 190 ms two-way travewltime (~150 m) is an artifact which has not been removed.
