B a c kground: Earth sciences is one of those sensitive field sciences that are closely needed to solve local problems within local physical and social settings. Earth researchers find state-of-the-art of topics in earth sciences by using scientific databases, conduct research on the topics, and write about them. However, the accessibility, readability, and usability of those articles for local communities are major problems in measuring the impact of research, although it may be covered by well-known international scientific databases. Obj ectives: To ascertain empirically whether there are differences in document distribution, in the proportions of openly accessible documents, and in the geographical coverage of earth sciences topics as revealed through analyses of documents retrieved from scientific databases and to propose new measures for assessing the impact of research in earth sciences based on those differences. M e th ods: Relevant documents were retrieved using ‘earth sciences’ as a search term in English and other languages from ten databases of scientific publications. The results of these searches were analysed using frequency analysis and a quantitative- descriptive design. Results: (1) The number of articles in English from international databases exceeded the number of articles in native languages from national-level databases. (2) The number of open-access (OA) articles in the national databases was higher than that in other databases. (3) The geographical coverage of earth science papers was uneven between countries when the number of documents retrieved from closed-access commercial databases was compared to that from the other databases. (4) The regulations in Indonesia related to promotion of lecturers assign greater weighting to publications indexed in Scopus and the Web of Science (WoS) and publications in journals with impact factors are assigned a higher weighting. Conclusions: The dominance of scientific articles in English as well as the paucity of OA publications indexed in international databases (compared to those in national or regional databases) may have been due to the greater weighting assigned to such publications. Consequently, the relevance of research reported in those publications to local communities has been questioned. This article suggests some open-science practices to transform the current regulations related to promotion into a more responsible measurement of research performance and impact.

Background: Open access (OA) implies free and unrestricted access to and re-use of research articles. Recently, OA publishing has seen a new wave of interest, debate, and practices surrounding that mode of publishing. Obj ectives: To provide an overview of publication practices and to compare them among six countries across the world to stimulate further debate and to raise awareness about OA to facilitate decision-making on further development of OA practices in earth sciences. M e th ods: The number of OA articles, their distribution among the six countries, and top ten journals publishing OA articles were identified using two databases, namely Scopus and the Web of Science, based mainly on the data for 2018. Results: In 2018, only 24%–31% of the total number of articles indexed by either of the databases were OA articles. Six of the top ten earth sciences journals that publish OA articles were fully OA journals and four were hybrid journals. Fully OA journals were mostly published by emerging publishers and their article processing charges ranged from $1000 to $2200. Conclusions: The rise in OA publishing has potential implications for researchers and tends to shift article-processing charges from organizations to individuals. Until the earth sciences community decides to move away from journal-based criteria to evaluate researchers, it is likely that such high costs will continue to maintain financial inequities within this research community, especially to the disadvantage of researchers from the least developed countries. However, earth scientists, by opting for legal self- archiving of their publications, could help to promote equitable and sustainable access to, and wider dissemination of, their work.

Diversity, at every step along the scientific path, drives innovative research. Scientific societies, like the Geochemical Society (GS) and the European Association of Geochemistry (EAG), have a significant influence over which discoveries and innovators are celebrated. Such choices impact the future of research, and therefore influence the evolution of our discipline and its relationship to the global community. Our professional societies are well positioned to define and promote the success of all scientists, including those from under-represented groups, through proactive advocacy, inclusive mentorship, awards, and leadership. At present, only binary gender data are available to examine the distribution of under-represented groups among memberships, awardees, and leadership positions. To assess gender diversity in the geochemistry and cosmochemistry community, we have reviewed available records of GS and EAG membership through Goldschmidt Conference attendees, and compared these to awardees and leadership data. Awards have in the past been disproportionately given to white men, though this is changing. The GS and EAG have taken positive steps to increase both diversity of awardees (e.g., broadened definition of Fellows criteria) and inclusion (e.g., mentoring efforts aimed at early career and underrepresented minority scientists). This work identifies strategies to continue to improve professional societies’ recognition of excellent science resulting in a more diverse representation of awardees. The strategies (e.g., revisions to award criteria and procedures to enlarge and diversify nomination pools) will require ongoing analysis and modifications. Future work is needed to address historically under-represented groups. We must work together to create a legacy of inclusion.

The elevated concentrations of rare earth elements (REE) and yttrium (REE+Y) in acid mine drainage (AMD) constitute an opportunity for REE+Y recovery. However, the source and control of REE+Y signatures in AMD remains uncertain. Water, rock, sediment and sludge samples were collected from an ion-adsorption rare earth mining area to investigate REE+Y concentration and fractionation patterns in AMD. High concentrations of REE+Y occur in the pristine mine water (MW), and decrease progressively with MW passing through nitrification-denitrification (NDT) and coagulating-precipitation (CPT) treatment procedures in a water treatment plant. Concentrations of REE+Y are 1 to 3 orders of magnitude higher in MW, NDT and CPT samples than those in well water (WW), and are negatively correlated (R2 0.72) with pH (3.8 to 8.7), suggesting that an enhanced acidic dissolution of minerals contributes REE+Y to AMD from the source area. Speciation calculation indicates that REE+Y are mainly free ions and sulfate complexes in MW and NDT samples, while carbonato and dicarbonato complexes in CPT samples. Normalized REE+Y patterns of water samples show a coherent enrichment of heavy REE (HREE) over light REE (LREE) and negative Ce anomalies. HREE-enriched patterns and Ce anomalies are kept relatively constant in MW, NDT and CPT samples, despite their huge disparity in REE+Y concentrations, indicating a limited impact of preferential precipitation of LREE over HREE on REE+Y fractionations. The HREE-enriched patterns possessed by AMD are similar to those of sediment samples, while are distinct from whole rocks. These behaviors suggest a major role of sediment source in controlling REE+Y concentrations and patterns in AMD. Results of XRD show abundance of muscovite, kaolinite and feldspar in sediments. Combining to SEM-EDS examinations, minerals such as kaolinite, schwertmannite (Fe16O16(SO4)3(OH)6(H2O)10·10H2O) and ferrihydrite are suggested to be the main hosts of REE+Y in sediments. Hence, HREE-enriched patterns of AMD result from preferential leaching of HREE from sediments which accumulate REE+Y after being initially mobilized from rocks under the conditions prevailing in mine site. The free form and sulfate complexation preserves REE+Y patterns and facilitates REE+Y mobility in the AMD system. Based on the plant treatment capacity, the potentially recoverable LREE and HREE are calculated to range between 1116 g/day and 3373 g/day, and between 1288 g/day and 3764 g/day, respectively.

The use of the term “heavy metal” is regularly questioned by the scientific community. Here, we followed the evolution (1970–2020) in the number of published papers including this term in their title. Thus, we can evidence a continuous, albeit sometimes stabilizing, increase especially in environmental journals. After several other warning opinions, we propose that it should be replaced in the scientific literature by terms like “metal”, “metalloid”, “trace metal elements” or “potentially toxic element”.

Diversity, at every step along the scientific path, drives innovative research. Scientific societies, like the Geochemical Society (GS) and the European Association of Geochemistry (EAG), have a significant influence on which innovators are celebrated. Such choices have the consequence of shaping the future of research, and so are responsible for the evolution of our discipline and its relationship to the global community. These professional bodies are uniquely positioned to define and promote the success of all scientists, including those from under-represented groups, through proactive advocacy, inclusive mentorship, awards, and leadership. At present, the only data available to examine the distribution of under-represented groups between memberships, awardees leadership are those of gender. To assess gender diversity in the geochemistry and cosmochemistry community, we thus introspectively review available records of GS and EAG membership through Goldschmidt Conference attendees, awardees, leadership, and editorial boards. This work identifies areas for growth and begins a dialogue about how the society and its members can work together to better reflect and progress our community. Our examination of the record spanning the last decade demonstrates that leadership positions, awards, and honors have continued to be disproportionately given to white men, to the exclusion of women. The GS and EAG have recently taken positive steps towards becoming more inclusive; however, much more work is needed. In order for both communities to become diverse, equitable and inclusive, where all scientists flourish, we offer suggestions for swift steps that the GS and EAG and their members can pursue. The suggested structural improvements will require ongoing analysis and reforms, which must be shared by all of us, to create a sustainable legacy that we can be proud of.

The communication presented here focusses on international disparities in open access publication practices of the Earth Science community. We provide an overview of actual publication practices and comparison between several countries (from Global North and Global South; China, Denmark, France, Indonesia, South Africa, United Kingdom and United States of America) with the intention of stimulating further debate and raising awareness to aid the decision-making processes for the further development of open access practices in the Earth Sciences. This communication represents the authors’ opinions on the reasons for and background of the actively developing practice of scientific publishing via open access, as well as briefly contrasting the current conditions of academic publishing in different countries.

Background: The researcher’s need to construct the state-of-the-art of a topic in Earth sciences is the only plausible reason to use scientific databases. However, nowadays, the primary function of such databases is often mixed up, confused with functions that are not intended for it, such as to select content based on language (e.g. English vs. Non-English issue), as well as to rank publications based on certain metrics. It is urgent to prove the fallacy of the trending use of the indexation.Objectives: This study aims to describe empirically whether there are differences in document distribution, openly accessible documents, and geographical coverages of Earth sciences topics based on searched scientific databases, as the basis for proposing new perspectives in Earth sciences research assessment.Methods: Document selection using ‘Earth sciences’ keywords in English and native languages was done on ten databases. Quantitative-descriptive design with a frequency analysis technique was employed. Results: (1) The number of English-written articles in international databases significantly exceeded the number of those written in native languages that were detected in national-level databases; (2) The sum of open access (OA) articles in national databases is higher than in other databases; (3) The geographical coverages of Earth sciences documents are unbalanced between countries when comparing retrievals from closed-commercial databases with the other databases. Conclusions: Earth sciences is one of the geographical sensitive field sciences that is closely needed to solve local problems with local physical and social settings. A combination of quantitative and qualitative measurements are very much needed in research performance assessment. Keywords: database bias; indexation; national database; Earth Science; Indonesia

In this communication, we look at Open Access (OA) publishing practices in geochemistry. We examine a list of 56 journals and assess whether Article Processing Charges (APCs) and Journal Impact Factors (JIFs) appear to influence publication or not. More than 40% of articles in 2018-2019 were published OA, and about 70% of that portion in fully OA journals. These had a mean APC of US$ 900, whereas the remaining were published in hybrid journals with a higher mean APC of more than $US 1,800. A moderate and positive correlation is found between the number of OA articles published in hybrids journals and their JIF, whereas there is a stronger positive relationship between the number of OA articles published in fully OA journals and the APC. For OA articles published in hybrid journals, it seems that the proportion of OA articles tends to increase in journals with higher JIF.

In recent years, the pace of the dissemination of scientific information has increased. In this context, the possibility and value of sharing open access (OA) online manuscripts in their preprint form seem to be growing in many scientific fields. More and more platforms are especially dedicated to free preprint publishing. They are published, non-peer-reviewed scholarly papers that typically precede publication in a peer-reviewed journal. They have been a part of science since at least the 1960s. In 1990, Tim Berners-Lee created the World Wide Web to help researchers share knowledge easily. A few months later, in August 1991, as a centralized web-based network, arXiv was created. arXiv is arguably the most influential preprint platform and has supported the fields of physics, mathematics and computer science for over 30 years. Since, preprint platforms have become popular in many disciplines (e.g., bioRxiv for biological sciences) due to the increasing drive towards OA publishing, and can be publisher- or community-driven, profit or not for profit, and based on proprietary or free and open source software. A range of discipline-specific or cross-domain platforms now exist, with exponential growth these last five years. While preprints as a whole still represent only a small proportion of scholarly publishing, a strong community of early adopters is already beginning to experiment with such value-enhancing tools in many more disciplines than before. The two main options for geochemists are EarthArXiv and ESSOAr. A “one size fits all” model for preprints would never work across the entire scientific community. The geochemistry community needs to develop and sustain their own model.

Struvite is increasingly considered a promising alternative to mined phosphorus (P) fertilizer. However, its solubility is very low under neutral to alkaline pH while it increases with acidification. Here, we investigated whether supplying ammonium to stimulate rhizosphere acidification might improve struvite solubility at the vicinity of roots and, ultimately, enhance P uptake by plants. Using a RHIZOtest design, we studied changes in soil pH, P availability and P uptake by ryegrass in the rhizosphere and bulk soil supplied with either ammonium or nitrate under three P treatments: no-P, triple super phosphate and struvite. We found that supplying ammonium decreased rhizosphere pH by more than three units, which in turn increased soluble P concentrations by three times compared with nitrate treatments. However, there was no difference between P treatments, which was attributed to the increase of soluble Al concentration in the rhizosphere, which subsequently controlled P availability by precipitating it under the form of variscite-like minerals (predicted using Visual MINTEQ). Moreover, although ammonium supply increased soluble P concentration, it did not improve P uptake by plants, likely due to the absence of P deficiency. Further studies, especially in low-P soils, are thus needed to elucidate the role of nitrogen form on P uptake in the presence of struvite. More generally, our results highlight the complexity of manipulating rhizosphere processes and stress the need to consider all the components of the soil-plant system.

There is no clear-cut boundary between Free and Open Source Software and Open Scholarship, and the histories, practices, and fundamental principles between the two remain complex. In this study, we critically appraise the intersections and differences between the two movements. Based on our thematic comparison here, we conclude several key things. First, there is substantial scope for new communities of practice to form within scholarly communities that place sharing and collaboration/open participation at their focus. Second, Both the principles and practices of FOSS can be more deeply ingrained within scholarship, asserting a balance between pragmatism and social ideology. Third, at the present, Open Scholarship risks being subverted and compromised by commercial players. Fourth, the shift and acceleration towards a system of Open Scholarship will be greatly enhanced by a concurrent shift in recognising a broader range of practices and outputs beyond traditional peer review and research articles. In order to achieve this, we propose the formulation of a new type of institutional mandate. We believe that there is substantial need for research funders to invest in sustainable open scholarly infrastructure, and the communities that support them, to avoid the capture and enclosure of key research services that would prevent optimal researcher behaviours. Such a shift could ultimately lead to a healthier scientific culture, and a system where competition is replaced by collaboration, resources (including time and people) are shared and acknowledged more efficiently, and the research becomes inherently more rigorous, verified, and reproducible.

Open Access (OA) describes the free, unrestricted access to and re-use of research articles. Recently, a new wave of interest, debate, and practice surrounding OA publishing has emerged. In this paper, we provide a simple overview of the trends in OA practice in the broad field of geochemistry. Characteristics of the approach such as whether or not an article processing charge (APC) exists, what embargo periods or restrictions on self-archiving' policies are in place, and whether or not the sharing of preprints is permitted are described. The majority of journals have self-archiving policies that allow authors to share their peer reviewed work via green OA without charge. There is no clear relationship between journal impact and APC. The journals with the highest APC are typically those of the major commercial publishers, rather than the geochemistry community themselves. The rise in OA publishing has potential impacts on the profiles of researchers and tends to devolve costs from organizations to individuals. Until the geochemistry community makes the decision to move away from journal-based evaluation criteria, it is likely that such high costs will continue to impose financial inequities upon research community. However, geochemists could more widely choose legal self-archiving as an equitable and sustainable way to disseminate their research.

There are major challenges that need to be addressed in the world of scholarly communication, especially in the field of environmental studies and in the context of the United Nations Sustainable Development Goals. Recently, Sonne et al. (2020) published an article in Science of the Total Environment discussing some of these challenges. However, we feel that many of the arguments misrepresent critical elements of Open Access (OA), Plan S, and broader issues in scholarly publishing. In our response, we focus on addressing key elements of their discussion on (i) OA and Plan S, as well as (ii) Open Access Predatory Journals (OAPJ). The authors describe OA and Plan S as restricting author choice, especially through the payment of article-processing charges. The reality is that 'green OA' self-archiving options alleviate virtually all of the risks they mention, and are even the preferred 'routes' to OA as stated by both institutional and national policies in Denmark. In alignment with this, Plan S is also taking a progressive stance on reforming research evaluation. The assumptions these authors make about OA in the "global south" also largely fail to acknowledge some of the progressive work being done in regions like Indonesia and Latin America. Finally, Sonne et al. (2020) highlight the threat that OAPJs face to our scholarly knowledge production system. While we agree generally that OAPJs are problematic, the authors simultaneously fail to mention many of the excellent initiatives helping to combat this threat (e.g., the Directory of Open Access Journals). We call for researchers to more effectively equip themselves with sufficient knowledge of relevant systems before making public statements about them, in order to prevent misinformation from polluting the debate about the future of scholarly communication.
