Synthesis of regional crust and upper-mantle structure from seismic and gravity data [PDF]
Available seismic and ground based gravity data are combined to infer the three dimensional crust and upper mantle structure in selected regions. This synthesis and interpretation proceeds from large-scale average models suitable for early comparison ...

Determining Geological Properties by a Hybrid Seismic-Magnetotelluric Approach [PDF]
, 2002 This paper concerns the controlled source audio magnetotelluric technique (CSAMT) for imaging subsurface structure. Given the short time available, we limited our investigation to a simple 1D earth model where regional seismic and well logs suggest ...

Journal of Quaternary Science, EarlyView.ABSTRACT Like other perialpine basins and glaciated margins, the Geneva Basin in SW Switzerland is characterised by buried tunnel valleys, which are elongated incisions widely attributed to subglacial meltwater erosion beneath continental ice sheets. However, an inclusive understanding of the geological control on the evolution of the glacial landscape

Developing a seismic pattern interpretation network (SpiNet) for automated seismic interpretation
, 2018 Seismic interpretation is now serving as a fundamental tool for depicting subsurface geology and assisting activities in various domains, such as environmental engineering and petroleum exploration. However, most of the existing interpretation techniques are designed for interpreting a certain seismic pattern (e.g., faults and salt domes) in a given ...

Neural network with signal parameters featuring for near‐surface velocity model building
Near Surface Geophysics, EarlyView.Abstract This study presents a method that integrates spectral recomposition (SR) with a neural network to improve near‐surface seismic analysis. The approach incorporates SR‐derived wavelet‐timing attributes into a fully convolutional network (FCN) to enhance the characterization of shallow subsurface structures. Field evaluation was conducted using S‐

People and Nature, EarlyView.Abstract Indigenous Peoples in northern Alberta, including Dené and Cree of the Athabasca Chipewyan and Mikisew Cree First Nations (ACFN and MCFN), have been using Indigenous laws and stewardship principles to care for their homelands for thousands of years. Since ACFN and MCFN signed Treaty 8 with Canada in 1899, Alberta's land management policies and

Negative Stiffness Induced and Controlled by Constriction
physica status solidi (b), EarlyView.Structures with negative stiffness can be stabilized by constriction of external displacement. Furthermore, constriction can make a conventional positive stiffness material exhibit negative stiffness, either bidirectional or unidirectional (shown in the figure).
