Short summary

As part of a geothermal project in Delft, the Netherlands, a 500 m deep multifunctional research borehole and monitoring station (called DAPGEO-02) was drilled in spring 2022. Cores and other solid samples were taken using a comprehensive logging programme using tools lowered into the borehole, and sensitive instruments were installed to measure any minor seismicity. The data from this borehole are publicly available, and physical sample requests can be made to promote scientific discovery.
