The SEIS experiment is now fully operational on Mars following the successful landing of the InSight mission in late November, 2018 and the installation of the seismometer and its wind protection on the Martian surface in early 2019.
After more than one year of operation, the InSight mission has now recorded several hundred of events and has collected long time series for the 6 seismic channels and pressure/wind channels. These data sets enable now systematic data analysis, enabling stack/cross-correlation on both events and noise and enhancement of the signal to noise thanks to pressure decorrelation and other noise correction
The goal of this postdoc will be to develop automatic seismic signal processing technics on the InSight SEIS data pipeline, on both the detected events and on noise, and to initiate waveform inversions for 1D and 3D structure with local and regional events, including through the search of long period signals associated to either events or to continuous excitation of Mars micro-seismic noise.
About 20% of the postdoc activities will be devoted to one of the weekly SEIS operation activities.
The candidate will therefore have to demonstrate his/her skill in broadband (0.1-10 Hz) seismic data processing, and must curious as the SEIS Mars data are new with respect to Earth seismic standard.
Experience in seismic modelling will be also welcome, as well/or is site effects modelling and/or crustal seismic exploration.
The Paris Institute of Physics of the Globe is a large higher education and research establishment. It brings together more than 500 people: researchers recruited from all over the world, engineers, technicians, administrative agents and post-doctoral students and doctoral students from all countries sharing the same passion for the sciences of the Earth, planets and the environment. Many cooperation agreements are set up with prestigious foreign institutions, allowing permanent scientific exchanges around the world.
The planetology and space sciences team is one of the components of the Paris Institute of Globe Physics. It participates in the preparation of future space missions in planetology and Earth observation, designs and produces on-board instruments and develops research themes in planetology and Earth observation.
The Postdoc, funded by the Mars Geophysics for InSight (MAGIS) ANR funded project, will join the IPGP SEIS team, a group of about 10 scientists, postdoc, PhDs and engineers. Although most of the activity will be held in the Planetary and Space Science Team of IPGP, there will be strong interaction with the Seismology team of IPGP.
