Overview

Top Research Topics at Estonian Journal of Earth Sciences?

The journal is mainly concerned with subjects like Paleontology, Ordovician, Geochemistry, Devonian and Conodont. Biostratigraphy, Baltica, Stage (stratigraphy), Facies and Biozone are among the areas of Paleontology tackled. While work presented in it provided substantial information on Ordovician, it also covered topics in Sedimentary rock, Fauna, Taxon and Genus.

  • Paleontology (49.09%)
  • Ordovician (23.48%)
  • Geochemistry (10.67%)

What are the most cited papers published in the journal?

  • Calcareous tubeworms of the Phanerozoic (87 citations)
  • The succession of Hirnantian events based on data from Baltica: brachiopods, chitinozoans, conodonts, and carbon isotopes (80 citations)
  • Three global carbon isotope shifts in the Silurian of Podolia (Ukraine): stratigraphical implications (51 citations)

Research areas of the most cited articles at Estonian Journal of Earth Sciences:

The journal publications facilitate discussions on Paleontology, Ordovician, Isotopes of carbon, Climatology and Baltica. The most cited articles with studies in Paleontology featured incorporate elements of Excursion and Chemostratigraphy. The Tremadocian studies presented in the most cited papers fall under the field of Ordovician, but they also have connections to other fields such as Monophyly.

What topics the last edition of the journal is best known for?

  • Ecology
  • Paleontology
  • Genus

The previous edition focused in particular on these issues:

The journal aims to foster the development of research in Paleontology, Geochemistry, Ordovician, Holocene and Slope stability. The journal explores issues in Paleontology which can be linked to other research areas like Chemostratigraphy and Core (optical fiber). The presented Geochemistry study covers related areas such as Tremadocian, Mineral chemistry and Gneiss and also touches on topics like Pressure temperature.

While Estonian Journal of Earth Sciences focused on Ordovician, it was also able to explore topics like Sedimentary basin, Tectonics, Ostracod, Ridge (meteorology) and Facies. The research on Holocene featured in Estonian Journal of Earth Sciences combines topics in other fields like Groundwater flow, Pleistocene, Fire frequency, Physical geography and Artesian basin. Research in Slope stability tackled falls within the umbrella of Geotechnical engineering.

The most cited articles from the last journal are:

  • Fire frequency during the Holocene in central Latvia, northeastern Europe (1 citations)
  • Geochemistry, mineral chemistry and pressure–temperature conditions of the Jõhvi magnetite quartzites and magnetite-rich gneisses, NE Estonia (1 citations)
  • Three-dimensional slope stability model of the Turaida castle mound (0 citations)

Papers citation over time

A key indicator for each journal is its effectiveness in reaching other researchers with the papers published at that venue.

The chart below presents the interquartile range (first quartile 25%, median 50% and third quartile 75%) of the number of citations of articles over time.

Publication chance based on affiliation

The publication chance index shows the ratio of articles published by the best research institutions in the journal edition to all articles published within that journal. The best research institutions were selected based on the largest number of articles published during all editions of the journal.

The chart below presents the percentage ratio of articles from top institutions (based on their ranking of total papers).Top affiliations were grouped by their rank into the following tiers: top 1-10, top 11-20, top 21-50, and top 51+. Only articles with a recognized affiliation are considered.

During the most recent 2021 edition, 100.00% of publications had an unrecognized affiliation. Out of the publications with recognized affiliations, nan% were posted by at least one author from the top 10 institutions publishing in the journal. Another nan% included authors affiliated with research institutions from the top 11-20 affiliations. Institutions from the 21-50 range included nan% of all publications and nan% were from other institutions.

Returning Authors Index

A very common phenomenon observed among researchers publishing scientific articles is the intentional selection of journals they have already attended in the past. In particular, it is worth analyzing the case when the authors participate in the same journal from year to year.

The Returning Authors Index presented below illustrates the ratio of authors who participated in both a given as well as the previous edition of the journal in relation to all participants in a given year.

Returning Institution Index

The graph below shows the Returning Institution Index, illustrating the ratio of institutions that participated in both a given and the previous edition of the conference in relation to all affiliations present in a given year.

The experience to innovation index

Our experience to innovation index was created to show a cross-section of the experience level of authors publishing in a journal. The index includes the authors publishing at the last edition of a journal, grouped by total number of publications throughout their academic career (P) and the total number of citations of these publications ever received (C).

The group intervals were selected empirically to best show the diversity of the authors' experiences, their labels were selected as a convenience, not as judgment. The authors were divided into the following groups:

  • Novice - P < 5 or C < 25 (the number of publications less than 5 or the number of citations less than 25),
  • Competent - P < 10 or C < 100 (the number of publications less than 10 or the number of citations less than 100),
  • Experienced - P < 25 or C < 625 (the number of publications less than 25 or the number of citations less than 625),
  • Master - P < 50 or C < 2500 (the number of publications less than 50 or the number of citations less than 2500),
  • Star - P ≥ 50 and C ≥ 2500 (both the number of publications greater than 50 and the number of citations greater than 2500).

The chart below illustrates experience levels of first authors in cases of publications with multiple authors.
