The 2nd edition of Research.com ranking of the best scientists in the
discipline of Earth Science relies os data
consolidated from multiple data sources including OpenAlex and
CrossRef. The bibliometric data for devising the citation-based metrics were
collected on 21-12-2022. Position in the ranking is based on a
researcher’s D-index (Discipline H-index), which
includes exclusively papers and citation
values for an examined discipline.

The scope of our Earth Science research
Research.com’s best scholars ranking is a credible
lineup of leading scholars from the area of
Earth Science, established by means of a detailed
analysis of 166,880 researchers discovered
from multiple bibliometric data sources. For the discipline of
Earth Science, as many as 7636 researchers were
examined.
What is D-index acceptance threshold for Earth Science
The D-index threshold for approving a researcher to be
considered is placed at 30 if
the majority of of their publications are in the area of Earth Science. The
acceptance factors for researchers to be
considered into the ranking of top scholars are based on the D-index, proportion
of the contributions made within the given field of study
as well as the awards and achievements of the scientists. The
D-index threshold for considering top researchers is
set as an increment of 10 depending on the overall number of scientists
projected for each discipline whilst
ensuring that the top 1% of best scholars are
added into the list. We expect a proximity of
30% or less between a researcher’s general H-index and their D-index.
Additional verification methods
As our leading goal is to ensure that only
genuine scientists are mentioned in
Research.com ranking we realize that metrics are never
supposed to be an absolute measure to assess the
work of scholars. This is why
we manually inspect every profile and cross-correlate it against publications in a
varied range of trustworthy sources. Although it’s not a
factor impacting a researcher’s position in
the ranking, the number of documents published in
well-known journals and conference proceedings should constitute a
credible secondary implication of their contribution to research in a
specific field of study. Position in the ranking is
established using each researcher’s D-index
using information compiled from OpenAlex and
CrossRef, which are the most credible and well-known bibliometric
databases of this kind available to the research community. A
thorough explanation of our research procedures
can be found on our
methodology page.
Our agenda
Our aim is to inspire scholars,
businessmen and politicians
worldwide to investigate where prominent experts are heading
and to offer a way for the whole research community to
get to know who the leading experts in specific
fields of research, in various countries, or even within research
institutions are.
