How to publish in this journal


As in many areas of science, mathematics has also gained an unprecedented importance in geosciences. The complexity of the processes within the Earth, at its surface, and in the atmosphere can only be described, modelled, mapped, and understood by means of modern mathematical methodologies. GEM – The International Journal on Geomathematics encourages interdisciplinary research in this respect. It publishes high quality peer-reviewed mathematical papers which are (also) relevant in Earth sciences. This includes all kinds of mathematical methodologies (algebraic, analytic, computational, numerical, operator-theoretic, optimization-based, statistical, stochastic etc.) in every possible discipline of geosciences (such as, but not exclusively, climatology, exploration, fractured porous media modelling, geodynamics, geology, geomagnetics, hydrology, oceanography, satellite data analysis, seismology, solid Earth physics, and time series analysis) but also planetary sciences and cosmology. While GEM is a mathematical journal, we also welcome research papers from applied scientists who present innovations or enhancements for the mathematical techniques in their expertise. Moreover, we interpret geomathematics in the broader sense that also mathematical novelties for other applications but with applicability in Earth sciences are appreciated. There are numerous areas of applied mathematics with strong interrelations with geomathematics such as fluid dynamics and medical imaging, just to mention a few.

The SJR is a size-independent prestige indicator that ranks journals by their 'average prestige per article'. It is based on the idea that 'all citations are not created equal'. SJR is a measure of scientific influence of journals that accounts for both the number of citations received by a journal and the importance or prestige of the journals where such citations come from It measures the scientific influence of the average article in a journal, it expresses how central to the global scientific discussion an average article of the journal is.

Total Documents

Evolution of the number of published documents. All types of documents are considered, including citable and non citable documents.

Citations per document

This indicator counts the number of citations received by documents from a journal and divides them by the total number of documents published in that journal. The chart shows the evolution of the average number of times documents published in a journal in the past two, three and four years have been cited in the current year. The two years line is equivalent to journal impact factor ™ (Thomson Reuters) metric.

Total Cites 

Evolution of the total number of citations and journal's self-citations received by a journal's published documents during the three previous years.
Journal Self-citation is defined as the number of citation from a journal citing article to articles published by the same journal.

Cites per Doc

Evolution of the number of total citation per document and external citation per document (i.e. journal self-citations removed) received by a journal's published documents during the three previous years. External citations are calculated by subtracting the number of self-citations from the total number of citations received by the journal’s documents.
