The Regional Oceanographic Data Base (BaRDO) contains 25,845 quality-controlled oceanographic stations acquired by INIDEP research vessels in the Southwest Atlantic. This paper describes the operability of the data management system, the characteristics and accuracy of the dataset, the quality-control procedures, and the main errors detected and corrected during the flagging process. In addition, we present information on the geographical and temporal distribution of the data, the evolution of the dataset in response to technological advances, and recommendations for its use. BaRDO contains two main data types: quasi-continuous CTD profiles (conductivity, temperature, and depth) and discrete, low-resolution OSD (Ocean Station Data) profiles. The majority of observations comprise temperature and salinity, while fluorometry, oxygen, and turbidity are also available when measured.
