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.
