The Geo-INQUIRE transnational access portfolio encompasses a variety of state-of-the-art laboratories, experimental sites and computational resources enabling the development of excellent ground-breaking science. Below there is a list of the Geo-INQUIRE Transnational Access installations and their descriptions.

Transnational Access (TA) to selected research facilities of the ECCSEL research infrastructure. ECCSEL-ERIC, the European Research Infrastructure for CO₂ Capture, Utilisation, Transport and Storage (CCUS) is making five of its facilities available through the Geo-INQUIRE project.

Access to Software as a Service (SaaS) and Workflows as a Service (WaaS) in combination with High Performance Computing (HPC) facilities. These computational services center around the fields of seismology, volcanology, tsunami science and geohazard analysis. They involve resources from the Centre of Excellence for Exascale in Solid Earth (ChEESE-CoE), European Plate Observing System (EPOS-ERIC), HPC infrastructure of the Consorzio Interuniversitario (CINECA) and the European Earthquake Hazard and Risk (EFEHR). 

The selected testbeds represent state-of-the-art research infrastructures, covering diverse domains of the geospehere (the Earth's interior, atmosphere and sea), and different spatial scales (from small-scale laboratories to field observatories), with the goal of monitoring land, sea and air environments. They involve resources from the European Multidisciplinary Seafloor and Water Column Observatory (EMSO-ERIC), the Bedretto Underground Laboratory for Geosciences and Geoenergy (BedrettoLab), Ella-Link GeoLab Madeira, and the European Plate Observing System (EPOS-ERIC).
