Abstract. Since 2000 and for the following 20 years hydrological data of the Mediterranean Sea, with a particular focus on the western and central Mediterranean sub-basins, have been acquired to study the hydrodynamics at both coastal and open sea scales. Totally 1468 hydrological casts were realized in 29 oceanographic cruises planned due to scientific purposes linked with funding research projects but sometimes driven by sea conditions and type of vessel. After an accurate quality assurance and control, following standard procedures, all hydrological data were included in four online public open access repositories in SEANOE available from (Ribotti et al., 2022). Hydrological and dissolved oxygen data are always present in all the datasets whereas pH, fluorescence, turbidity and CDOM are available just for some cruises. Samplings were carried out mainly along transects with some repetitions in the years. Then the results of two data analyses, staircase systems in the Tyrrhenian Sea and in the Algero-Provencal sub-basin and spreading of the Western Mediterranean Transient, are mentioned.

Short summary
Over 1468 hydrological vertical profiles were acquired in 21 years in the Mediterranean Sea. This allowed to follow the diffusion of the Western Mediterranean Transient along all western seas or make some important repetitions across straits, channels or at defined locations. This amount data is now available in four open access online datasets, composed by profiles of water temperature, conductivity, dissolved oxygen, Chlorophyll-α fluorescence and, after 2004, turbidity and, once, pH.
