Data Sources and Citation Metrics
The 5th edition of the Research.com Best Earth Science Scientists in Panama Ranking is founded on comprehensive bibliometric data primarily sourced from OpenAlex and CrossRef, complemented by a variety of additional reputable databases. These sources collectively offer extensive and up-to-date records of scholarly publications, citations, and related metadata. Bibliometric data collection for the citation-based metrics utilized in constructing this ranking was completed on January 12, 2026. A scientist’s position in the ranking is determined based on their D-index (Discipline H-index), a metric that exclusively evaluates papers and citation impact within the specific discipline under examination—in this case, Earth Science.
Scope of Research and Qualification Criteria
The ranking assessment began with an examination of 279,971 scientist profiles identified through multiple bibliometric platforms spanning all scientific disciplines. Of those, 2 scientists were identified specifically within the Earth Science discipline. To qualify for inclusion in the ranking, a scientist must meet a minimum D-index threshold of 30, ensuring a substantial and measurable impact within Earth Science. Additionally, the majority of a qualifying scientist’s key publications must focus on Earth Science topics. Awards and notable achievements relevant to Earth Science were also taken into account as supplementary factors in evaluating scientific contribution.
It is important to note that the D-index threshold is methodically calibrated in increments of 10, reflecting the estimated total scholar population within each discipline, while simultaneously ensuring representation of the top 1% of leading researchers. Furthermore, qualifying scientists exhibit a proximity of 30% or less between their general H-index and their D-index, which confirms their focused expertise within Earth Science while maintaining an overall strong citation profile.
Verification and Validation Practices
The team behind this ranking fully acknowledges that raw bibliometric data alone cannot be considered an absolute measure of scholarly impact or output. Consequently, each scientist profile underwent manual verification, including cross-correlation with publication records across an array of trustworthy sources. This rigorous validation ensures integrity and accuracy in representing the contributions of each individual.
Although not directly influencing the numerical ranking position, the volume of publications in prominent journals and keynote conference proceedings is considered a valuable secondary indicator of a scientist’s influence and contribution within Earth Science.
The reported ranking positions are established strictly on the basis of each researcher’s D-index as derived from OpenAlex and CrossRef—the most recognized and trusted bibliometric databases accessible to the academic community.
