Research Data Publication: how to do it FAIR and open

The talk deals with current standards in data publication, explains researchers´ role in making data findable, accessible, interoperable and re-usable (FAIR), and covers legal aspects including data licensing. While data repositories, publishers and institutions all have their own roles in enabling “FAIR and open” publishing, this talk focuses on the perspective and core tasks of researchers for best practice in research data publication

Andreas Hübner has been working as liaison librarian for the geosciences at the University Library of Freie Universität Berlin since summer 2021. He holds a PhD in geology and worked as postdoc at the University of Utrecht, The Netherlands. He joined the GFZ German Research Center for Geosciences in 2006, working on various projects related to public relations and science communication. His last project at GFZ was working five years for the Specialised Geoscience Information Service FID GEO. In this respect he was also part of the research data team at the GFZ.

Scientific drilling in the Oman ophiolite: new insights into the mechanism of accretion of fast-spreading oceanic crust

Invited by: Harry Becker

The talk deals with Scientific drilling in the Oman ophiolite in the frame of the ICDP (International Scientific Continental Drilling Program) Project "The Oman Drilling Project", which aims to test models related to the formation and alteration of oceanic lithosphere. The results of investigating the crustal drill cores embedded in an effort to present a reference section through the whole Oman paleocrust leads to a deeper understanding of the mechanism of accretion of fast-spreading oceanic crust.

After studying "Mineralogy" at the Technische Universität Braunschweig, I worked at the University of Hannover, where I used experimental and microanalytical methods. My main interests are the geodynamics of mid-ocean ridges with focus on magmatic processes at the interface between igneous and hydrothermal processes and the role of water during construction of the ocean crust.

It takes a village to run a model

Models are frequently used tools in research, and often perceived as objective tools to create new knowledge or to support decision making. In this talk, I will discuss social processes that influence modelling, and that therefore have implications on the objectivity of models. If we start to acknowledge that models are social constructs, we might adapt our way of working with models to the better of science and decision support.

Bio:
Lieke works as an assistant professor in the field of Computational Hydrology at Wageningen University, the Netherlands. During her PhD, she investigated technical uncertainty in hydrological models. This made her realize that the results were conditional on her own decisions, and made her decide to focus research on the decision-making process in the selection and configuration of models. She is now involved in research projects that focus on different parts of modelling, from participatory approaches to the development of good modelling practice guidelines.

Surge of ore metals in seawater and increased bio-activity in an Archaean VHMS deposit

The Nimbus Ag–Zn(–Au) deposit is a hybrid VHMS deposit with epithermal characteristics formed in the Eastern Goldfields Superterrane, Yilgarn Craton, under shallow water (~ 700 mbsl), low-temperature conditions. Trace elements in sedimentary nodular pyrite from multiple intervals along a single drillhole (NBDH010), indicate the existence of a sedimentary layer of enriched ore-metal content. Within this enriched interval, proxies indicate that the black shale matrix of the polymict conglomerate records increased bio-activity at that time, interpreted to be associated with the Ag–Zn(–Au) mineralization. The consequences of these observations are two-fold, they help better understand the paleo-envirement where increased biological activity would be recorded during the Archean, as well as help us develop exploration strategies in the search for similar deposits.

Vitor Barrote is a Postdoctoral researcher at the AG Geochemistry group at Freie Universität Berlin. His research interests lie in the field of isotopic geochemistry and geochronology, with a special interest in technical development and the use of multidisciplinary studies applied in unorthodox ways in order to solve unusual problems. He believes that mineral deposits are rare records of amplified geological processes, and could hold fundamental keys to the understanding of major questions that every geoscientist asks themself: the history of Earth’s evolution, the spark of life and what makes our planet so special. Vitor Barrote is also a member of the Traveling Geologist team and the host for Gneiss Chats on the Geology Podcast Network.

Identification of stress loading sources in the brittle crust at various scales: examples from Southern California and beyond

Earthquakes are violent processes associated with movement of the rock mass along fractures/faults, originating from continuous changes in the stress and strain field. Improved determination of the stress field is crucial for advancing in estimating seismic hazard and identifying main drivers of crustal deformation. At long wavelengths, the regional stress pattern is largely controlled by the plate motion. For intraplate regions, where distance from the plate boundary increases, additional loading sources become prominent, including surface loading or isostatic compensation. However, as earthquake detection capabilities improve due to densification of seismic networks, heterogeneities in the stress field can be resolved at regional and even at local scale. In this talk I review some of the main stress loading sources that influence the stress field at regional to local scale, including (1) the effect of local topography, (2) the presence of geological structures, (3) co-seismic stress changes, and (4) anthropogenic stress loading. I will illustrate the role of some of these local stress loading sources in the deformation and mechanics of faulting from some regions of the San Andreas Plate Boundary System, including the San Jacinto Fault Zone and the South Central Tranverse Ranges.

Bio:
I studied Fundamental Physics and a Master in Geophysics and Meteorology at the Universidad Complutense of Madrid. Then, I studied my PhD at the GFZ Potsdam and Free University of Berlin on the topic of “Seismo-mechanical characterization of fluid-induced seismicity”. I currently lead a Helmholtz Young Investigators Group at GFZ Potsdam (SAIDAN: www.saidan.org) related to the study of crustal deformation processes spanning a broad range of frequencies from seismic to aseismic. My main interests concern the study of earthquake physics and the imaging of fault state of stress and how can we utilize them to refine the assessment of seismic hazard.

Experimental study on fluid-driven carbonation of the forearc mantle

Significant amounts of carbon are released from the subducting slab into fluids, but less carbon is outgassed in arc volcanoes. This study investigates the fate of COH-fluids when they travel through the (partially) hydrated forearc mantle targeting the forearc mantle as a potentially relevant carbon reservoir.
Thermodynamic modelling and piston‑cylinder experiments are utilized to gain a comprehensive understanding on phase relations, trace element partitioning, reaction magnitudes and timescales when COH‑fluids infiltrate into serpentinites and peridotites between 1‑2.5GPa and 375‑750°C. The results are applied to carbonated high‑pressure rocks from the Western European Alps.

Bio:
Melanie Sieber is a Postdoctoral researcher at the AG Mineralogy at the University of Potsdam and lab manager of the internally heated gas-pressure vessel (IHPV) lab (GeoX Joint lab between University of Potsdam and GFZ). She holds a PhD in experimental petrology from the Australian National University and investigates by performing high pressure and temperature experiments the stability of carbonates in the upper mantle and the partitioning of trace element during crustal anatexis.
