    Abstract The rate of science information's spread has accelerated in recent years. In this context, it appears that many scientific disciplines are beginning to recognize the value and possibility of sharing open access (OA) online manuscripts in their preprint form. Preprints are academic papers that are published but have not yet been evaluated by peers. They have existed in research at least since the 1960s and the creation of ArXiv in physics and mathematics. Since then, preprint platforms—which can be publisher- or community-driven, profit or not for profit, and based on proprietary or free and open source software—have gained popularity in many fields (for example, bioRxiv for the biological sciences). Today, there are many platforms that are either disciplinary-specific or cross-domain, with exponential development over the past ten years. Preprints as a whole still make up a very small portion of scholarly publishing, but a large group of early adopters are testing out these value-adding tools across a much wider range of disciplines than in the past. In this opinion article, we provide perspective on the three main options available for earth scientists, namely EarthArXiv, ESSOAr/ESS Open Archive and EGUsphere.

    Abstract The ability of biochar to immobilize metals relies on the amount of functional groups at its surface but the contribution of each functional groups (e.g. carboxylic, phenolic) to metal bonding is poorly known. Using a new approach based on previous works on rare earth element (REE) interactions with humic substances, we aim at elucidating the relative contribution of these binding sites to metal sorption under various conditions (i.e. pH and ionic strengths, IS). Using batch experiments, REE sorption onto biochar was analyzed from pH 3 to 9 and IS 10−1 mol/L to 10−3 mol/L. Rare earth element patterns show a Middle REE (MREE) downward concavity at acidic pH and low ionic strength. These patterns are in good agreement with existing datasets quantifying REE binding with humic substances. Indeed, the MREE downward concavity displayed by REE-biochar complexation pattern compares well with REE patterns with various organic compounds. This similarity in the REE complexation pattern shapes suggests that carboxylic groups are the main binding sites of REE in biochar. Overall, our results indicate that the strength of the metal bonding with biochar increases when pH and IS increase, suggesting that biochar is more efficient for long-term metal immobilization at near neutral pH and high ionic strength.

    Abstract 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.

    Abstract Background: 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.Objectives: 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.Methods: 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 ...

    Abstract Abstract The results of this study allow the reassessment of the rare earth elements (REE) external cycle. Indeed, the river input to the oceans has relatively flat REE patterns without cerium (Ce) anomalies, whereas oceanic REE patterns exhibit strong negative Ce anomalies and heavy REE enrichment. Indeed, the processes at the origin of seawater REE patterns are commonly thought to occur within the ocean masses themselves. However, the results from the present study illustrate that seawater-like REE patterns already occur in the truly dissolved pool of river input. This leads us to favor a partial or complete removal of the colloidal REE pool during estuarine mixing by coagulation, as previously shown for dissolved humic acids and iron. In this latter case, REE fractionation occurs because colloidal and truly dissolved pools have different REE patterns. Thus, the REE patterns of seawater could be the combination of both intra-oceanic and riverine processes. In this study, we show that the Atlantic continental shelves could be considered potential REE traps, suggesting further that shelf sediments could potentially become a resource for REE, similar to metalliferous deep sea sediments.

    Abstract Rare earth elements (REE) are known to be emerging contaminants in hydrosphere, but roles of hydrous manganese oxyhydroxides (HMO) in REE transport in groundwater remains unknown. In this study, groundwater was sampled along a flow path in the North China Plain to determine the behavior of REE surface complexation to HMO by a modeling and field study approach. Results show that the proportion of neodymium (Nd) complexed by HMO ranges from 0.2% to 95.8%, and from 0.3% to 99.6% in shallow groundwater and deep groundwater, respectively. The amount of complexed REE increases along the flow path. REE bound to HMO exhibit decreasing trends with increasing atomic number. The process was determined to be independent of pH, HMO content, and metal loading. This finding further demonstrates HMO-REE complexation plays a key role in transport of REE in groundwater through preferential scavenging of light REE (LREE) over heavy REE (HREE). Nevertheless, carbonate ligands appear to be robust competitors in reducing the amount of REE sorbed to HMO when solution pH rises above 8.0. Assuming that 50% of Mn concentration occurs as HMO, the amount of complexed REE was predicted to show a more marked decrease in LREE compared to that of HREE.
