Beschreibung: Digital infrastructures have become indispensable in the field of modern research and science. These technological frameworks play a crucial role for the entire research cycle, supporting literature searches, aiding in data collection and analysis, facilitating the creation and publication of scholarly works, and ensuring the thorough documentation and long-term storage of research findings. Additionally, these infrastructures serve as a vital means for networking and communication among peers, creating the essential foundation of an open and transparent science and research ecosystem. Helmholtz employees were invited to join the Helmholtz Open Science Forum "Towards Open Digital Research Ecosystems - Interconnection Infrastructures" on February 14, 2024, where options for the seamless integration of these digital infrastructures have been discussed. Speakers presented insights into diverse efforts to the provision of open infrastructure structures and how their interconnection offers new possibilities for seamless and integrated workflows within the increasingly digitized research. Further, it was examined how such an integrated ecosystem can support open science practices and vice versa

Beschreibung: Mit der Nationalen Forschungsdateninfrastruktur (NFDI) verfolgen Bund und Länder das Ziel, Datenbestände aus der Forschung für das deutsche Wissenschaftssystem nach den FAIR-Prinzipien systematisch zu erschließen, damit diese für Dritte besser zugänglich gemacht werden. Die NFDI wird als Netzwerk von Konsortien über einen Zeitraum von drei Jahren ab 2020 in drei aufeinanderfolgenden Förderphasen aufgebaut. Eine wichtige Rolle spielt dabei auch die Abdeckung disziplinübergreifender Querschnittsthemen. Zur Förderung des Dialogs zur NFDI in der Helmholtz-Gemeinschaft veranstaltete das Helmholtz Open Science Office am 4. Mai 2021 ein digitales Helmholtz Open Science Forum unter dem Motto „Helmholtz in der Nationalen Forschungsdateninfrastruktur (NFDI)“. Als Impuls für die weitere Diskussion lud das Helmholtz Open Science Office alle interessierten Mitarbeitenden der Helmholtz-Gemeinschaft zu diesem virtuellen Helmholtz Open Science Forum ein. Neben einer Einführung durch das NFDI-Direktorat stellten Vorträge die Bandbreite der NFDI-Beteiligung in Helmholtz dar (z. B. Praxisberichte bereits bewilligter Konsortien sowie Vorträge zum Umgang mit der NFDI aus Perspektive eines Zentrums, eines Forschungsbereichs und einer Plattform des Inkubators “Information & Data Science”); auch wurde das Zusammenspiel von NFDI und European Open Science Cloud (EOSC) vom Büro Brüssel der Gemeinschaft beleuchtet. Im Kern stand die Identifikation und Diskussion zu Helmholtz-spezifischen Aspekten bei der Realisierung der NFDI.

Beschreibung: Zum Austausch von Best Practices aus den Zentren und zur Förderung der FDM-Community in Helmholtz veranstaltete das Helmholtz Open Science Office am 3. Februar 2022 das erste „Helmholtz Open Science Praxisforum Forschungsdatenmanagement“. In dem Helmholtz-internen Forum wurden exemplarisch verschiedene Herangehensweisen aus Zentren zur Organisation des FDM vorgestellt. Darüber hinaus standen konkrete Service-Angebote zu FDM im Mittelpunkt. Außerdem wurde die Vernetzung mit externen Akteuren, z. B. im Rahmen der NFDI, EOSC oder der RDA, beleuchtet. Die regen Diskussionen verdeutlichten den hohen Bedarf nach übergreifendem Community-Building im Bereich des FDM innerhalb von Helmholtz und darüber hinaus.

Beschreibung: Present day system Earth research utilizes the tool ‘Scientific Drilling’ to access samples and to monitor deep Earth processes that cannot be tackled by other scientific means. Unlike most laboratory experiments or computer modelling, drilling projects are massive field endeavours requiring intense collaboration of researchers with engineers and service providers. In the framework of the International Continental Scientific Drilling Program, ICDP, more than seventy drilling projects have been conducted, from multiyear big research programs to short, smallscale deployments such as lake drilling projects. ICDP has supported these projects not only through grants covering field-related costs, but also through a variety of scientific-technical services and support, as well as active help in data management, outreach and publication. These services are described in this booklet. Due to its instructional character, we call it the ICDP Primer.

Beschreibung: This brochure is designed for scientists and engineers of upcoming drilling projects and explains the key steps and important challenges in planning and executing continental scientific drilling.

Beschreibung: Reconstructions of global hydroclimate during the Common Era (CE; the past ∼2000 years) are important for providing context for current and future global environmental change. Stable isotope ratios in water are quantitative indicators of hydroclimate on regional to global scales, and these signals are encoded in a wide range of natural geologic archives. Here we present the Iso2k database, a global compilation of previously published datasets from a variety of natural archives that record the stable oxygen (δ18O) or hydrogen (δ2H) isotopic compositions of environmental waters, which reflect hydroclimate changes over the CE. The Iso2k database contains 759 isotope records from the terrestrial and marine realms, including glacier and ground ice (210); speleothems (68); corals, sclerosponges, and mollusks (143); wood (81); lake sediments and other terrestrial sediments (e.g., loess) (158); and marine sediments (99). Individual datasets have temporal resolutions ranging from sub-annual to centennial and include chronological data where available. A fundamental feature of the database is its comprehensive metadata, which will assist both experts and nonexperts in the interpretation of each record and in data synthesis. Key metadata fields have standardized vocabularies to facilitate comparisons across diverse archives and with climate-model-simulated fields. This is the first global-scale collection of water isotope proxy records from multiple types of geological and biological archives. It is suitable for evaluating hydroclimate processes through time and space using large-scale synthesis, model–data intercomparison and (paleo)data assimilation. The Iso2k database is available for download at https://doi.org/10.25921/57j8-vs18 (Konecky and McKay, 2020) and is also accessible via the NOAA/WDS Paleo Data landing page: https://www.ncdc.noaa.gov/paleo/study/29593 (last access: 30 July 2020).

Beschreibung: A vision for the establishment of a Geopark in Jordan is given in this work, with a subsequent application to the UNESCO Global Geopark programme. The Dead Sea area and its surroundings have suffered strong changes in the last decades, accompanied by a variety of natural hazards related to enhanced erosional processes. The aspiring Geopark will thematically encompass the influence that these changes and related natural hazards, including flash floods and subsidence, have had on the local population, from geological, over historical up to recent times. The hydrogeology and geomorphology, i.e., the connection between erosion by water, dissolution of minerals, and landscape evolution, will be the main guiding theme that connects the Eastern Rim Highlands with the Dead Sea rift valley through ephemeral wadis, vegetated springs areas, and traditionally communities. The creation of the Geopark is aimed at holistic, sustainable development and management of the area by eco-tourism, and includes education on water resource management, hazard awareness and resilience, as well as international research. We here present the conceptual approach to the initial development of a Geopark network in Jordan. In a narrative discourse, we highlight realised and further implementation steps, with an evaluation of the expected timeline, potential partner institutions, regional involvement and the chances for realisation.

Beschreibung: Riverine nutrient export is an important process in marine coastal biogeochemistry and also impacts global marine biology. The nitrogen cycle is a key player here. Internal feedbacks regulate not only nitrogen distribution, but also primary production and thereby oxygen concentrations. Phosphorus is another essential nutrient and interacts with the nitrogen cycle via different feedback mechanisms. After a previous study of the marine nitrogen cycle response to riverine nitrogen supply, we here additionally include phosphorus from river export with different phosphorus burial scenarios and study the impact of phosphorus alone and in combination with nitrogen in a global 3-D ocean biogeochemistry model. Again, we analyse the effects on near coastal and open ocean biogeochemistry. We find that the addition of bio-available riverine phosphorus alone or together with nitrogen affects marine biology on millennial timescales more than riverine nitrogen alone. Biogeochemical feedbacks in the marine nitrogen cycle are strongly influenced by the additional phosphorus. Where bio-available phosphorus is increased by river input, nitrogen concentrations increase as well, except for regions with high denitrification rates. High phosphorus burial rates decrease biological production significantly. Globally, riverine phosphorus leads to elevated primary production rates in the coastal and open oceans.
