        The dataset contains seafloor pressure data acquired by the seismic hydrophone installed on NEMO-SN1 observatory in the frequency band 50mHz - 1kHz. Pressure is sampled at 2kHz rate by two A/D converter (12 bit) which supply two data channel (with low, 30dB and  high, 60 dB gain). Pressure data are stored in counts units; 1 count corresponds to 0.546 Pa and 0.0172 Pa for low and high gain channel respectively. Absolute time reference is available thanks to GPS data embedded in each packet of data and distributed from land station to seafloor. The wide frequency range allows to study acoustic ambient noise in the deep water, detect sperm whale and cetaceans and detect seismic signals. It was designed to be able to detect also low frequency hydroacustic signal generated by a tsunami in case this was generated by large seismic event on the seafloor. The set contains 292.5 Gbyte of data stored in 52560 files of ten minutes each and covers 8717.82 hours of acquisition (292.5 days) which was continuous during the mission, excluding some periods when acquisition was stopped for observatory maintenance and calibrations.
