Seafloor pressure data from two SBE53 pressure gauges on EMSO-Azores observatory, 2019-2020
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.

Devices
SBE53 Bottom Pressure Recorder (BPR). The sensor measures full ocean depth water level. It provides bottom pressure records by combining a time base with low-power frequency-acquisition circuitry, a Paroscientific Digiquartz® pressure transducer, a non-volatile 32 MB FLASH memory and a precision thermometer.
Parameters: seafloor pressure in psi and seafloor temperature °Celsius
