Abstract

This dataset contains seafloor pressure data acquired in the framework of EMSO-Azores observatory between June 2019 and September 2020 using SBE53 pressure gauges deployed on two sites. West site : The sensor was deployed on an existing benchmark installed with the submersible Nautile in August 2006 during the GRAVILUCK cruise (https://doi.org/10.17600/6010110). The benchmark sits on hard substratum with light hydrothermal sedimentation, on the North-West border of the Lucky Strike lava lake, next to a hydrothermal site. East site : The sensor was deployed on an existing benchmark installed by freefall in July 2007 during the MOMARDREAM cruise (https://doi.org/10.17600/7030060). The benchmark sits in the axial valley, East of the LuckyStrike volcano in a lightly sedimented area, with apparent pillow lavas. Instrument location bathymetric map
