Best Earth Science Scientists in Iceland

The 2nd edition of ranking of the best researchers in the field of Earth Science is based on data combined from a wide range of data sources including OpenAlex and CrossRef. The bibliometric data for evaluating 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 publications and citation values for an examined discipline.

The range of our Earth Science research’s best scholars ranking is a credible account of leading researchers from the area of Earth Science, established by means of a thorough study of 166,880 scientists determined from multiple bibliometric data sources. For the discipline of Earth Science, as many as 7637 scientists were investigated.

What is D-index approval threshold for Earth Science
The D-index threshold for including a scientist to be considered is established at 30 if the majority of of their publications are in the area of Earth Science. The inclusion criteria for researchers to be considered into the ranking of top researchers are based on the D-index, ratio of the publications made within the selected discipline as well as the awards and achievements of the scientists. The D-index threshold for listing leading scientists is set as an increment of 10 depending on the overall number of scholars projected for each area od study whilst guaranteeing that the top 1% of best researchers are added into the list. We expect a proximity of 30% or less between a scientist’s general H-index and their D-index.

Other verification methods
As our primary goal is to guarantee that only credible scientists are mentioned in ranking we are aware that numbers are never supposed to be a full measure to assess the work of scientists. This is why we manually verify each profile and cross-correlate it against publications in a wide range of credible sources. Although it’s not a factor impacting a researcher’s position in ranking, the number of documents published in major journals and conference proceedings should constitute a reliable secondary signal of their contribution to research in a selected discipline. Position in the ranking is based on each scholar’s D-index according to information collected from OpenAlex and CrossRef, which are the most prominent and well-known bibliometric databases of this kind accessible to the scientific community. A comprehensive explanation of our research policy can be found on our methodology page.

Our goal
Our aim is to motivate researchers, entrepreneurs and decision-makers around the world to explore where prominent experts are heading and to provide an opportunity for the whole scientific community to discover who the leading experts in specific fields of research, in various countries, or even within research institutions are.
