The South African Geodynamic Observatory Sutherland (SAGOS) of GFZ was established during the years 1998 – 2000 based on an Agreement on Cooperative Activities between the National Research Foundation (NRF) and GFZ, signed in August 1998. SAGOS is located at the site of the South African Astronomical Observatory (SAAO). The operation and maintenance of the SAGOS instrumentation is jointly done by staff of SAAO and GFZ.
Geothermal Technologies: continuous microgravity monitoring for integrated mass and stress balance analysis in a volcanic geothermal field - contribution for exploitation sustainability in Indonesia and Iceland - MikroGraviMoTiS
Mass distribution changes are monitored by simultaneous measurements of spatially distributed high-performance, high-frequency gravitymeters in an operated geothermal field, to better understand the related reservoir processes.
