Quartiles

The set of journals have been ranked according to their SJR and divided into four equal groups, four quartiles. Q1 (green) comprises the quarter of the journals with the highest values, Q2 (yellow) the second highest values, Q3 (orange) the third highest values and Q4 (red) the lowest values.

SJR

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.

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.

Country	Netherlands	120 H Index
Subject Area and Category	Earth and Planetary Sciences Earth-Surface Processes Environmental Science Environmental Chemistry Water Science and Technology
Publisher	Kluwer Academic Publishers
Publication type	Journals
ISSN	01682563, 1573515X
Coverage	1984-ongoing
Scope	Biogeochemistry publishes original papers and occasional reviews dealing with biotic controls on the chemistry of the environment, or with the geochemical control of the structure and function of ecosystems. Cycles are considered, either of individual elements or of specific classes of natural or anthropogenic compounds in ecosystems. Particular emphasis is laid on the interactions of element cycles. The journal covers global aspects of biogeochemistry in the form of work on the global carbon and sulfur cycles, for instance. Studies on both natural and artificial ecosystems are published when they contribute to a general understanding of biogeochemistry. (source)
