Abstract:
The data comprise continuous records of seismic raw data acquired with ocean bottom seismometers (OBS). The data were collected at Venere mud volcano during expedition POS515 with the research vessel POSEIDON (Riedel et al., 2017) in the Mediterranean Sea, Calabrian Arc offshore southern Italy (map under further details). The entire data set consists of 11 OBS stations. Each OBS consist of 4 channels (channel 1: hydrophone; channel 2: horizontal component 1; channel 3: horizontal component 2; channel 4: vertical component). Data are not corrected for clock-drift. Data format is Passcal-SEGY. Data are accessible using the seismological software tools provided by EarthScope: https://www.passcal.nmt.edu/content/software-resources. The data were recorded using: HTI-04_PCA_ULF hydrophones from High Tech Inc., Short-period 4.5 Hz geophones and three-component seismometers (K/MT-210 manufactured by KUM GmbH). The recording device is an MBS recorder of SEND GmbH.

Comment:
Data are stored for each OBS location separately. Data comprise the entire recording period. We are using the Julian Day numbering convention. There are 11 OBS stations in total (V01, V02, V03, V04, V05, V06, V07, V08, V09, V11, V12). Julian days are from day 171 (= June 20, 2017) until day 183 (= July 2, 2017).
Physical location of OBS drop position can be found in the associated cruise report (Riedel et al., 2017).
A data-file for any given OBS has a name following this format:
e.g. V.01.17.171.16.56.18.0504.4
V.*..*....**. Venere mud volcano: V

...*...18.***** Second of the start of the record: 18
...*....0504. Serial number of the MBS-Recorder: 0504
...*....***.4 This value is the recorded channel (1= hydrophone, 2= horizontal 1, 3 = horizontal 2, 4 = vertical)
Sampling rate of the recordings was at 1000 Hz.
