For the integration of this dataset, several research articles were collected from the catalog of The Global Heat Flow Data Assessment Project. Specifically, those that reported heat flow values within Mexican territory and in the country's surrounding seas.

The updated database now comprises 1230 heat-flow determinations compiled from 25 different publications. Within this dataset, 49% of the entries represent continental heat-flow data (onshore), while the remaining 51% correspond to marine data (offshore). This data set covers a period from 1970 to 2022. Notably, 92% of the reported heat flow values were obtained via direct temperature measurements (47% through borehole drilling and 45% through probe sensing), while the remaining data (8%) were estimated from indirect methods, such as geothermometer and Curie depth temperature calculations.

The data are presented according to the standards defined by the World Heat Flow Database Project and the International Heat Flow Commission (Fuchs et al., 2023).
