Comparing results of an AI neural network method with a sparse optimization method for frequency-band reconstruction of seismic images

Motivated by environmental concern, the industry has been developing an alternative marine seismic source, in particular a marine vibrator. By spreading the emitted energy out over time, vibrator sources are perceived to be less intrusive to marine mammals. It is also believed that vibrators have greater control of the emitted source wavelet...

Near-Surface Characterization of Mars InSight Data by Polarization Analysis

On the 25th of November 2018, NASA’s InSight Mars-lander landed at Elysium Planitia on Mars (NASA, 2022a). The lander includes the SEIS instrument, which measures the seismic signals on the planet (NASA, 2022b). Because seismic waves are altered by the medium they travel through from the source to the receiver, they contain information on the...

Airborne geomagnetic mapping with an unmanned aerial vehicle: development of a sensor calibration scheme

In the last decade, technological advances in the field of multicopters enabled a widespread use of drones that include professional research applications covering a wide field from civil engineering to geosciences and agriculture. In recreational spheres drones became popular for sport and leisure activities like private photography. In...
