Data Sources and Bibliometric Information
The 5th edition of the Research.com Best Earth Science Scientists in Trinidad and Tobago Ranking is primarily based on comprehensive bibliometric data sourced from OpenAlex and CrossRef, among multiple other reputable academic data repositories. These platforms provide extensive metadata on scholarly publications, citations, and related metrics, forming the backbone for the citation-based indicators employed in our ranking methodology. The bibliometric data used to devise the citation-based metrics for this ranking were collected as of January 12, 2026.
A scientist’s position within the ranking is determined by their D-index (Discipline H-index), a refined bibliometric measure that considers only publications and citation metrics directly relevant to the examined discipline—in this case, Earth Science. This ensures that the ranking focuses on disciplinary impact rather than overall citation performance.
Scope of Research and Inclusion Criteria
The ranking framework began with a wide pool of 279,971 scientist profiles identified across diverse bibliometric data sources covering all academic disciplines globally. From this, 1 scientist specializing specifically in Earth Science in Trinidad and Tobago was thoroughly evaluated for inclusion.
To qualify for the ranking, scientists were required to have a D-index of at least 30. Additionally, a majority of their top-tier publications needed to be directly related to Earth Science to confirm disciplinary relevance. Beyond bibliometric indicators, scientists’ awards and documented achievements in Earth Science were also considered to present a holistic perspective on their contributions.
The threshold for the D-index varies incrementally by 10 points, depending on the estimated total number of scholars in each discipline, while ensuring that the top 1% of leading scholars within that field are captured. Moreover, to maintain alignment between general and discipline-specific impact, a proximity of 30% or less between a researcher’s overall H-index and their D-index was maintained as an additional quality control measure.
Verification Practices and Data Integrity
Recognizing that raw bibliometric data alone cannot absolutely evaluate scholarly output, the team behind the ranking conducted extensive manual verification of all scientist profiles. Each profile was cross-correlated against publications listed in a broad range of trusted academic sources to verify accuracy and attribution.
Although the number of papers published in prominent journals and conference proceedings does not directly influence a researcher’s ranking position, it serves as a valuable secondary indicator of a scientist’s substantive contributions within their scientific domain.
The final ranking positions are established based on each researcher’s D-index, calculated from curated data provided by OpenAlex and CrossRef—two of the most authoritative and widely recognized bibliometric databases available to the research community.
