Segmentation of Earth science imagery is an increasingly common task. Among modern techniques that use Deep Learning, the UNet architecture has been shown to be a reliable for segmenting a range of imagery. We developed software - Segmentation Gym - to implement a data-model pipeline for segmentation of scientific imagery using a family of UNet models. With an existing set of imagery and labels, [...]

Analytical and numerical modeling of viscous anisotropy: A toolset to constrain the role of mechanical anisotropy for regional tectonics and fault loading

Dunyu Liu, Simone Puel, Thorsten W. Becker, et al.

Published: 2022-07-12
Subjects: Education, Engineering, Physical Sciences and Mathematics

Whether mechanical anisotropy is required to explain the dynamics of the lithosphere, in particular near fault zones where it may affect loading stresses, is an important yet open question. If anisotropy affects deformation, how can we quantify its role from observations? Here, we derive analytical solutions and build a theoretical framework to explore how a shear zone with anisotropic viscosity [...]

Discoverability of open data is critical to Earth system science

Aditi Sengupta, Nicholas Ward, James Stegen

Published: 2022-06-21
Subjects: Education, Life Sciences

There is consensus throughout the Earth system science research community that “open data” is of critical importance. However, discoverability and accessibility are often overlooked, raising the question of how useful archived, but not easily discoverable data are. As part of evaluating databases suitable for our own research data archival, we conducted a data discovery exercise (aggregators and [...]

Recent innovations and cost reductions in photogrammetry-based 3D modeling have enabled museum visitors to create 3D models based on photographs exhibited in galleries without breaking museum policies. While several museums make 3D museum data available on sharing platforms, museum visitors publish unofficial 3D data belonging to museum exhibits using a photogrammetry-based approach. This [...]

The revolutionary impact of the Deep Time concept: Geology’s modernity and societal implications

Andrea Fildani

Published: 2022-02-05
Subjects: Education, Physical Sciences and Mathematics

I propose throughout this short op-ed that Geology, as one of the most recently established core sciences, is the one most at risk of societal misinterpretation precisely because of its innovativeness. The discovery of ‘deep time’ and the revelation of temporal change were triggered by the advance of geological methodology, which pushed the boundary of the scientific establishment of the time [...]
