The data publication contains all heat-flow data of offshore in the Guaymas basin. The data release contains data generated between 1959 and 2019 and constitutes a substantial update and extension compared to the last compilation provided by Becker & Fisher (1991). The data set comprises new heat-flow determinations published after 1991 as well as data from before 1991, which were not included in the Becker & Fisher (1991). The resulting updated database contains 487 determinations of heat-flow at 464 locations from 17 publications. 95% of the reported heat-flow values are determined from marine probe sensing technique and 5% in boreholes.

The reporting and storing of the database are following the structure of the IHFC Global Heat Flow Database (Fuchs et al., 2021). A comprehensive description, including field classifications and examples of associated data, is documented there. The IHFC database concept introduces parent elements (providing site-specific information), child elements (i.e., heat-flow values determined at the site and associated meta-data) and further fields providing additional information for the evaluation of heat flow quality. Thus, it provides a detailed collection of data and meta-data information, exceeding the sparse information on coordinates, name and heat-flow value.
