Surface underway measurements of partial pressure (or fugacity) of carbon dioxide, salinity and water temperature collected from the sailing vessel HOLCIM during the Vendée Globe 2024 race in the Atlantic Ocean, Pacific Ocean, Indian Ocean from 2024-11-10 to 2025-01-25 (NCEI Accession 0310919)
This dataset includes data collected from the race sailing vessel HOLCIM during the Vendée Globe 2024 race. A flow-through membrane pCO2 sensor is integrated with the SubCTech Ocean pack. The vessel sailed around the world, from and back to Les Sables D'Olonnes (France), sampling in the Atlantic Ocean, Indian Ocean and Pacific Ocean. The most recent calibration of this sensor occurred before the race, in fall 2024. The system is composed of only one temperature sensor, and SST and membrane temperature are assumed to be the same (even if this hypothesis could be flawed, and should be improved in the future). This system is equipped with three pressure sensor, one measuring atmospheric pressure, one measuring the differential pressure between the membrane and the LICOR, and the LICOR pressure. To estimate the pressure of the measurement we added the differential pressure and the LICOR pressure. Since the system is not vented, it is not at atmospheric pressure, and the readings of the pressure are therefore not following the atmospheric pressure variations but more the cycles of the system. We acknowledge that the salinity is noisy, we did not do any processing or filtering to remove the noise.
