This dataset contains raw data, drift corrected data and SeisComP 3 Data Structure (SDS) from Ocean Bottom Seismometers (OBS) deployed at EMSO-Azores from April 2015 to August 2016. The raw data are initialy in Lcheapo format. They are fixed at first to remove bugs and they are transformed to miniSEED format. The drift corrected data are obtained from fixed raw data. The drift corrected data are obtained from fixed raw data. A value is put in the Time Correction eld (eld 16) of each data header. By default, the correction is applied to the Record Start Time (eld 8) and the Time Correction Applied ag (eld 12, bit 1) is activated. Alternatively, only the Time Correction Applied eld is changed. Seiscomp3 Data Structure (SDS) is the final product. It's the correct structure to be use in the Seiscomp 3 software.

This dataset contains current data acquired between September 2016 and July 2017 using 2 TCM3 Ocean Bottom Tilt Current Meters installed next to the Tour Eiffel and Montségur hydrothermal vent sites. The TCM-3 Ocean Bottom Tilt Current Meter from Lowell Instruments LLC (North Falmouth, MA, USA) measures current using the drag-tilt principle. The logger is buoyant and is anchored to the bottom via a short flexible tether. Drag from moving water tilts the logger in the direction of flow. The logger’s accelerometer and magnetometer channels are used to record the amount of tilt and direction of tilt (compass bearing). The array comprised 3 currentmeters, deployed near the Tour Eiffel, Montségur and White Castle hydrothermal vent sites (the instrument at White Castle did not recover data). The array is not connected to an energy node. The currentmeter's internal clocks are set to UTC time before deployment. Clock drift after recovery is not implemented in data but added as metadata in the file "Sites and Sensor metadata".
