ClimEx high frequency sea level observations from low-cost pressure sensors at Blancs Sablons (Le Conquet, France)

The dataset consists of raw pressure data and sea level data from 27 low-cost bottom pressure sensors (Mastodon probes) sampling at 2 Hz. The low-cost sensors were deployed at Blancs Sablons (Le Conquet, France) during more than 4 months, from 14 December 2023 to 25 April 2024. The coordinate files (coord_sensors.txt) contains the longitude and latitude of the 27 sensors. The RAW_PRESSURE_DATA directory contains 27 files in text format (csv). The pressure files (climex_blancs_sablons_M*_P.csv) contain a header (10 lines), and then one line per time record (every 0.5 s), with the date, the temperature (°C), and the pressure (bar). The SEA_LEVEL_DATA directory contains 27 files in NetCdf format (climex_blancs_sablons_M*_sea_level.nc). The ’sea_level’ variable is expressed in meters and related to Chart Datum. The ’time’ variable is expressed in seconds and represents the number of elapsed days since 1970-01-01 00:00:00 UTC.   Important Note: This submission has been initially submitted to SEA scieNtific Open data Edition (SEANOE) publication service and received the recorded DOI. The metadata elements have been further processed (refined) in EMODnet Ingestion Service in order to conform with the Data Submission Service specifications.
