AlpArray Field Activity: UNIBRA/DSEBRA - the German contribution to the AASN

Project in SSP 4D-MB Mountain Building in four dimensions

UNIBRA / DSEBRA is the German contribution to the AlpArray Seismic Network (AASN). UNIBRA is a consortium of seven German universities and research institutions, which have installed 10 stations each with (mostly) institutional funding in order to ensure the timely completion of AASN ahead of DFG funding becoming available. DSEBRA is a designated set of one hundred broadband sensors and dataloggers (Nanometrics Horizon 120) hosted jointly by the universities of Bochum, Frankfurt, Münster and Kiel, which is dedicated exclusively to array studies and was purchased with AASN as its first mission. The DSEBRA stations will replace the UNIBRA stations at the same site from spring 2017 onwards. GFZ has a small role in this project in operating 10 broad-band sensors (Trillium 240) in Austria as its UNIBRA contribution. The GFZ UNIBRA stations are A15, A22, A23, A25-29, A31 and A34, available to AlpArray Core Group members under FDSN network code Z3.
