Best Earth Science Universities in Canada 2026

Institutions' positions in the ranking are determined by the aggregate of D-indexes (Discipline H-index) of all affiliated scholars whose primary area of publication is Earth Science. It is critical to note that the D-index only includes data on publications and citations specific to the Earth Science discipline, ensuring a focused and discipline-relevant evaluation.

Scope of the Evaluated Research

For this edition, a detailed assessment was conducted on 279,971 scientist profiles identified through various bibliometric data channels. From this pool, 31,170 researchers specializing in Earth Science were subject to in-depth analysis. Each scientist considered for the ranking had to meet a qualifying D-index threshold of 30, with the majority of their major publications situated firmly within the Earth Science domain.

Further, the evaluation protocol integrates qualitative measures such as a scientist’s awards and achievements in Earth Science. The D-index threshold used to filter top researchers is set in increments of 10, tailored to the total pool of scholars estimated for each discipline. This approach guarantees inclusion of at least the top 1% of leading scholars in every field. An additional criterion requires that there is at most a 30% difference between a scientist’s general H-index and their D-index to ensure genuine disciplinary expertise. The selection process doubly weighs significant recognitions and field-specific accomplishments of each candidate.

Additional Verification Practices

The researchers developing this ranking maintain a clear understanding that raw bibliometric data are not to be viewed as absolute measures of scholarly output. Accordingly, each scientist profile underwent thorough manual verification and was cross-validated against publications from a spectrum of trusted sources.

While the number of papers published in high-tier journals and conference proceedings does not contribute directly to a researcher’s rank within Research.com, it is acknowledged as an informative secondary indicator of influence and research contribution. The ultimate position in the ranking stems from each scientist’s H-index, with data meticulously extracted from OpenAlex and CrossRef—undoubtedly the most reliable bibliometric platforms available for academic research assessment.
