The 2nd edition of Research.com ranking of the best scientists in the
discipline of Earth Science relies os data
combined from a wide range of data sources including OpenAlex and
CrossRef. The bibliometric data for devising the citation-based metrics were
acquired on 21-12-2022. Position in the ranking is based on a
scientist's D-index (Discipline H-index), which
includes exclusively publications and citation
metrics for an examined discipline.

The focus of our Earth Science research
Research.com’s best scientists ranking is a reliable
list of leading scientists from the field of
Earth Science, established by means of a meticulous
examination of 166,880 scientists discovered
from various bibliometric data sources. For the area of
Earth Science, more than 7637 scientists were
examined.
What is D-index acceptance threshold for Earth Science
The D-index threshold for accepting a researcher to be
evaluated is established 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 researchers are based on the D-index, ratio
of the contributions made within the given area
in addition to the awards and achievements of the scholars. The
D-index threshold for considering leading scientists is
set as an increment of 10 depending on the overall number of scholars
estimated for each area od study whilst
guaranteeing that the top 1% of best scholars are
considered into the ranking. We estimate a proximity of
30% or less between a scholar’s general H-index and their D-index.
Additional verification methods
Because our primary goal is to make sure that only
credible scientists are mentioned in
our ranking we realize that numbers are never
meant to be a full tool to evaluate the
work of researchers. This is why
we manually verify every profile and cross-correlate it against publications in a
varied range of credible sources. Even though it’s not a
element impacting a researcher’s position in
the ranking, the number of documents published in
major journals and conference proceedings should constitute a
valuable secondary signal of their contribution to research in a
given discipline. Position in the ranking is
based on each scholar’s D-index
with the help of metrics collected from OpenAlex and
CrossRef, which are the most trustworthy and well-known bibliometric
databases of this kind accessible to the scientific community. A
thorough definition of our research policy
can be found on our
methodology page.
Our mission
Our goal is to inspire researchers,
companies and politicians
around the world to examine where top experts are heading
and to provide an opportunity for the entire research community to
get to know who the leading experts in specific
disciplines, in different countries, or even within research
institutions are.
