This dataset presents raw acoustic data in WAV format (sampling frequency : 256 kHz) recorded onboard R/V L'Atalante on March 9, 2025, between 12:30 and 16:30 UTC, off the West coast of Guadeloupe (Cruise ESSTECH-AT-2025-1: ship radiated noise measurement). Ambient noise data recorded on an acoustic recorder submerged 40m below the surface include numerous sound emissions from marine mammals (sperm whales observed visually in the area, other odontocetes and probably distant humpback whales).

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…
