This dataset contains the in situ oceanographic observations collected from using the 5th generation OceanPack by SubCtech to measure fCO2(pCO2,xCO2), sea surface salinity, chlorophyll a, and sea surface temperature. Besides, frequent samples were analyzed for microplastic concentration per cubic meter. The sampled water was pumped from the VO65 hulls scoop inlet at an average depth of 1.5 m for continuous measurements. Zero-calibrations were set to every 24 hours and autonomous span CO2 gas calibration was performed in every harbor after each leg. The observations in Europe were conducted from May to September 2019. The analysis for microplastic particle concentration was conducted according to Tanhua & Gutekunst et al. 2020, PLOS ONE (https://doi.org/10.1371/journal.pone.0243203, NCEI Accession 0170967).
