Overview

What this was about

Laura Tilley described GeoDARA, a six-month (May-November) EOSC Gravity small project by the CETAF Earth Science Group and partners exploring how earth science collection data can be made more FAIR through GeoCASe and connected to the EOSC thematic node DataTERRA. Three case-study datasets (Quaternary pollen records from Estonia, 7,500-year tree-ring isotope records from the University of Helsinki, and HMS Challenger foraminifera from NHM London) are being used to assess metadata such as object type, taxonomy, origin, age, depositional environment and provenance. A key finding is the mismatch between specimen-level standards (ABCD-EFG, Darwin Core) and DataTERRA's dataset-level DCAT, so the project is mapping between them and will deliver a demonstrator, guidance and an online training workshop on 28-29 October.

Why it matters. Earth science collections hold deep-time environmental records that are largely invisible outside the collections community; connecting them to EOSC could support climate and environmental research.

Key ideas

In the room

  • Earth science collections allow interdisciplinary, deep-time research but have low visibility, inadequate metadata and limited access.
  • GeoDARA is funded as a six-month small project under EOSC Gravity and aims to connect GeoCASe to DataTERRA, an EOSC thematic node for environmental and observation data.
  • Case studies: Estonian pollen records, Finno-Scandinavian tree-ring records (University of Helsinki) with oxygen/carbon isotopes, and HMS Challenger foraminifera (NHM London).
  • Collections use ABCD-EFG or Darwin Core at specimen level, whereas DataTERRA uses DCAT at dataset level, which cannot carry individual specimen information.
  • Next steps: complete the metadata assessment, improve datasets and possibly the GeoCASe data model, publish via GeoCASe, map to DCAT and produce a demonstrator plus guidance.
  • An online training/demonstrator workshop is planned for 28-29 October.

Programme abstract

Improving Access to Earth Science Collections Data via GeoCASe and the European Open Science Cloud

Laura Tilley

Earth Science collections curated by natural history museums and research institutions contain critical records documenting past climates, environmental change, natural hazards, biodiversity dynamics, and geological processes across deep time. Despite their considerable scientific and societal value, these data have often remained fragmented, inconsistently described, and difficult to integrate with other Earth observation datasets. The CETAF Earth Science Group (ESG) is working to improve the discoverability, interoperability, and reuse of Earth Science collections data across Europe. ESG is leading the further development of GeoCASe (https://geocase.eu), a data network, aggregation service, and web portal for geoscientific collections data. The recently launched EOSC-Gravity project “Geodera” aims to integrate geological specimen-and sample-level data within the European Open Science Cloud (EOSC) through their Data Terra thematic node. Geodera will use representative case studies from different branches of geology to analyse and identify researchers’ data service needs, and to evaluate the usefulness of collections-based records for scientific applications and cross-domain research. Particular attention will be given to metadata harmonisation with external research platforms and datasets, including Earth observation data services within EOSC and Data Terra. This work includes assessing existing TDWG community standards, such as ABCD and Darwin Core, together with their geoscience extensions, as well as emerging concepts such as digital specimens. The project will identify gaps in current metadata schemas, provide training and practical guidelines to improve data quality, expand the GeoCASe consortium, and strengthen interoperability across the Earth Sciences domain.
