Acoustic signal, data from the EGIM, EMSO-Azores observatory, 2017-2018

This dataset contains acoustic signal acquired between July 2017 and August 2018 on EMSO-Azores observatory by the EGIM. Acoustic signal is one of the 7 core parameters monitored by the EGIM, EMSO Generic Instrumental Module.

The EGIM prototype was deployed at Lucky Strike hydrothermal vent site, 25 m south west of the active edifice Tour Eiffel, to monitor local hydrodynamic variability and complement the data obtained by the numerous sensors set on this site: oceanographic mooring deployed south of the vent field, the multidisciplinary Seamon East node, autonomous current meters, array of temperature probes…
