This is a complete database of Lake Baikal sediment core AMS radiocarbon data from papers published before 2025. Most radiocarbon data has already been published but is not easily accessible on a public database. We also provide access to previously unpublished radiocarbon data from cores CON01-603-5 and CON01-605-5. The presented dataset amends previous reporting mistakes on the location of cores, the depth of samples and the Lab ID of some radiocarbon data. The data was collected to investigate the radiocarbon age offset (similar to reservoir age) in Lake Baikal. ** For all details see the full metadata description at "https://doi.pangaea.de/10.1594/PANGAEA.973799"!
