Abstract
The Geophysical Instrument Pool Potsdam (GIPP) consists of field instruments, sensors and equipment for temporary seismological studies (both controlled source and earthquake seismology) as well as for magnetotelluric (electromagnetic) experiments. These instruments are mainly mobile digital recorders, broadband seismometers and short period sensors, and they are used to reveal the subsurface structure and to investigate earthquakes. Sensors for magnetotellurics include induction coil and fluxgate magnetometers and non-polarizing silver / silver-chloride electrodes. It is operated by the Helmholtz Centre Potsdam GFZ German Research Centre for Geosciences. The instrument facility is open to all academic applicants, both national and international. Instrument applications are evaluated and ranked by an external steering board. Currently, for seismological applications >850 geophysical recorders, >170 broadband seismometers and >1300 short period geophones are available (among others). Available for magnetotelluric experiments are > 50 real-time data-loggers, >150 induction coils, and >500 electrodes. User guidelines and data policy are in force and data archives are provided (standard exchange formats).
Highlights
Geophysical eld measurements play an important role when investigating “System Earth” by providing new and important insight into the structure of our planet and ongoing processes

Due to the large size of the object under investigation experiments have to be carried out in situ in the eld and not in the lab. Most of these experiments are performed from the Earth’s surface, and they utilize for example elastic waves or electromagnetic elds
Summary
Geophysical eld measurements play an important role when investigating “System Earth” by providing new and important insight into the structure of our planet and ongoing processes. Due to the large size of the object under investigation (planet Earth) experiments have to be carried out in situ in the eld and not in the lab. Most of these experiments are performed from the Earth’s surface, and they utilize for example elastic waves (seismology) or electromagnetic elds (magnetotellurics). The Geophysical Instrument Pool Potsdam (GIPP) is a large infrastructure facility providing the equipment for these experiments such as digital recorders, seismometers, magnetometers and electrodes (www.gfz-potsdam.de/gipp). Between 1993 and 2015 the GIPP supported almost 300 experiments, and almost 400 ISI publications based on data gathered with GIPP instruments have been published (see full list via www.gfz-potsdam.de/gipp)
