Deep Prior-Based Unsupervised Reconstruction of Irregularly Sampled Seismic Data

open access: yesIEEE Geoscience and Remote Sensing Letters, 2022
Irregularity and coarse spatial sampling of seismic data strongly affect the performances of processing and imaging algorithms. Therefore, interpolation is a usual preprocessing step in most of the processing workflows. In this work, we propose a seismic

Upper mantle structure of Mars from InSight seismic data

open access: yesScience, 2021
Single seismometer structure Because of the lack of direct seismic observations, the interior structure of Mars has been a mystery. Khan et al., Knapmeyer-Endrun et al., and Stähler et al.

Application of high-resolution processing in seismic data based on an improved synchrosqueezing transform

open access: yesFrontiers in Earth Science, 2022
This study proposes a high-resolution processing technique for seismic data based on the improved synchrosqueezing transform (SST). The SST rearranges the complex spectrum of the wavelet transform along the frequency axis.

A High-Resolution Global Moho Model from Combining Gravimetric and Seismic Data by Using Spectral Combination Methods

open access: yesRemote Sensing, 2023
The high-resolution Moho depth model is required in various geophysical studies. However, the available models’ resolutions could be improved for this purpose.

Seismic data visualisation

open access: yes2015 38th International Convention on Information and Communication Technology, Electronics and Microelectronics (MIPRO), 2015
The focal mechanism of an earthquake and fault plane solutions provide insight into the geology of an area. The objective of this paper is to give a means of better understanding fault movement when an earthquake occurs. In this paper we present an interactive 3D visualisation of possible fault plane solutions, which are usually represented as 2D ...

Seismic Data Reconstruction Using Deep Bidirectional Long Short-Term Memory With Skip Connections

open access: yesIEEE Geoscience and Remote Sensing Letters, 2021
Due to environmental and economic constraints on their acquisition, seismic data are always irregularly sampled and include bad or missing traces, which can cause problems for seismic data processing.

Deep Convolutional Neural Network With Attention Module for Seismic Impedance Inversion

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023
Seismic inversion is an approach to obtain the physical properties of the Earth layers from the seismic data, which aids in reservoir characterization. In seismic inversion, spatially variable physical parameters, such as impedance ($Z$), wave velocities

The Denoising of Desert Seismic Data Based on Cycle-GAN With Unpaired Data Training

open access: yesIEEE Geoscience and Remote Sensing Letters, 2021
The seismic data with high quality are the essential foundation of imaging and interpretation. However, the real seismic data are inevitably contaminated by noise, which affects the subsequent processing and interpretation of seismic data.

Seismic Characteristics and Development of the Upper Jurassic Carbonate Buildups from the Miechów Trough (Southern Poland)

open access: yesGeosciences, 2020
The presented study is devoted to the subsurface Upper Jurassic carbonate buildups and surrounding stratified inter-buildup deposits in the hitherto less recognized area, in comparison with other parts of the northern Tethyan shelf in Poland and Europe ...

Characterising Seismic Data [PDF]

open access: yesProceedings of the 2014 SIAM International Conference on Data Mining, 2014
When a seismologist analyses a new seismogram it is oftenuseful to have access to a set of similar seismograms.For example if she tries to determine the event, if any,that caused the particular readings on her seismogram.So, the question is: when are two seismograms similar?To dene such a notion of similarity, we rst preprocessthe seismogram by a ...
