Dataset Information

The seismic waveform dataset of the Sardinia Passive Array Experiment (SPAE).

ABSTRACT: The Sardinia Passive Array Experiment (SPAE) was carried out in central-northern Sardinia (Italy), between July 2014 and September 2016, with the main goal of acquiring new data for studies on the lithospheric structure of Mediterranean region and seismicity of the Sardinia-Corsica block. The array consisted of 8 three-component portable seismographs, deployed progressively through the observing period. The stations operated in continuous mode recording at 100 sps, providing more than 50 GB of digital waveforms for the analysis. This data article describes the main characteristics of the temporary network and the valuable content of the seismic dataset assembled. The SPAE waveform dataset and the station metadata are accessible at the European Integrated Data Archive (EIDA) repository.

Project description:By the end of 2018, 42 years after the landing of the two Viking seismometers on Mars, InSight will deploy onto Mars' surface the SEIS (Seismic Experiment for Internal Structure) instrument; a six-axes seismometer equipped with both a long-period three-axes Very Broad Band (VBB) instrument and a three-axes short-period (SP) instrument. These six sensors will cover a broad range of the seismic bandwidth, from 0.01 Hz to 50 Hz, with possible extension to longer periods. Data will be transmitted in the form of three continuous VBB components at 2 sample per second (sps), an estimation of the short period energy content from the SP at 1 sps and a continuous compound VBB/SP vertical axis at 10 sps. The continuous streams will be augmented by requested event data with sample rates from 20 to 100 sps. SEIS will improve upon the existing resolution of Viking's Mars seismic monitoring by a factor of ∼2500 at 1 Hz and ∼200000 at 0.1 Hz. An additional major improvement is that, contrary to Viking, the seismometers will be deployed via a robotic arm directly onto Mars' surface and will be protected against temperature and wind by highly efficient thermal and wind shielding. Based on existing knowledge of Mars, it is reasonable to infer a moment magnitude detection threshold of Mw∼3 at 40∘ epicentral distance and a potential to detect several tens of quakes and about five impacts per year. In this paper, we first describe the science goals of the experiment and the rationale used to define its requirements. We then provide a detailed description of the hardware, from the sensors to the deployment system and associated performance, including transfer functions of the seismic sensors and temperature sensors. We conclude by describing the experiment ground segment, including data processing services, outreach and education networks and provide a description of the format to be used for future data distribution.Electronic supplementary materialThe online version of this article (10.1007/s11214-018-0574-6) contains supplementary material, which is available to authorized users.
