This dataset contains the technical parameters acquired between July 2017 and August 2018 on EMSO-Azores observatory with the COSTOF2 (COmmunication and STOrage Front-end 2nd generation) of the EGIM.

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…
