3D SEISMIC ANALYSIS OF CENOZOIC SLOPE DEPOSITS AND FLUID FLOW PHENOMENA ALONG THE NIGERIAN TRANSFORM MARGIN
Published: 2023-01-26
Subjects: Education
High-resolution 3D seismic data covering an area of 2,845 km2 provide new insights on slope deposits and fluid-flow phenomena along the Nigerian Transform Margin, focusing on the ~ 2 km thick Cenozoic post-transform succession. The study documents large-scale mass-transport complexes, deep-water channel complexes, sediment waves, and a wide range of fluid flow phenomena. The focused fluid flow [...]
A Data-driven Approach to Petroleum Engineering Problems
Published: 2023-01-19
Subjects: Education, Engineering
In this work, a data-driven approach is taken to tackle problems in Petroleum Engineering domain, for both conventional and unconventional reservoirs. Conventional reservoirs face the problem of losing energy for flowing after a few years of production, thus operators choose to inject water and inject CO$_2$ as a secondary and tertiary recovery method. The question of interest is that how [...]
Strategies for making geoscience PhD recruitment more equitable
Published: 2022-10-28
Subjects: Earth Sciences, Education, Outdoor Education, Physical Sciences and Mathematics
Doctoral study is a crucial part of the academic pipeline, but discriminatory admissions procedures disproportionately impact students from ethnic minority backgrounds. We examine how doctoral recruitment policies contribute to inequity in the geosciences and propose improvements for change.
A critical review of the sedimentary record of the `Millennium Eruption' of Changbaishan/Paektu-san volcano
Published: 2022-09-29
Subjects: Education
The `Millennium Eruption’ of Changbaishan/Paektu-san Volcano, situated today on border between the People's Republic of China and Democratic People's Republic of Korea, ranks as one of the largest eruptions of the Common Era. Dated to 946 CE, its tephra deposits represent a critical marker spanning terrestrial and marine archives, as well as the glacial record of Greenland. Its geographically [...]
The Equator Project
Published: 2022-09-10
Subjects: Education, Physical Sciences and Mathematics
Geography, Earth and Environmental Science (GEES) research will play a vital role in addressing the grand challenges of the 21st century, contributing to many of the UN sustainable development goals and the global energy transition. However, geoscience knowledge cannot be successfully applied to global problems that impact people from all walks of life unless the discipline itself is equitable. [...]
A Reproducible and Reusable Pipeline for Segmentation of Geoscientific Imagery
Published: 2022-09-07
Subjects: Education, Engineering, Life Sciences, Physical Sciences and Mathematics
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
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 [...]
Intercomparison of deep learning architectures for the prediction of precipitation fields
Published: 2022-07-07
Subjects: Education, Engineering
In recent years, the use of deep learning methods has rapidly increased in many research fields. Similarly, they have become a powerful tool within the climate scientific community. Deep learning methods have been successfully applied for different tasks, such as identification of atmospheric patterns, weather extreme classification, or weather forecasting. However, due to the inherent complexity [...]
Discoverability of open data is critical to Earth system science
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 [...]
Interactive Hydrological Modelling and Simulation on Client-Side Web Systems: An Educational Case Study

Subjects: Civil and Environmental Engineering, Earth Sciences, Education, Engineering, Engineering Education, Environmental Education, Environmental Engineering, Hydraulic Engineering, Hydrology, Numerical Analysis and Scientific Computing, Other Civil and Environmental Engineering, Physical Sciences and Mathematics, Science and Mathematics Education, Water Resource Management
Computational hydrological models and simulations are fundamental pieces of the workflow of contemporary hydroscience research, education, and professional engineering activities. In support of hydrological modelling efforts, web-enabled tools for data processing, storage, computation, and visualization have proliferated. Most of these efforts rely on server resources for computation and data [...]
Strategies for and Barriers to Collaboratively Developing Anti-racist Policies and Resources as Described by Geoscientists of Color Participating in the Unlearning Racism in Geoscience (URGE) Program
Published: 2022-04-07
Subjects: Earth Sciences, Education
The Unlearning Racism in Geosciences (URGE) program guides groups of geoscientists as they draft, implement, and assess anti-racist policies and resources for their workplace. Some participating Geoscientists of Color (GoC) shared concerns about microaggression, tokenism, and power struggles within their groups. These reports led us to collect and analyze data that describe the experiences of GoC [...]

Museum exhibitions of fossils into commercial products: Unexpected outflow of 3D models due to unwritten image policies into commercial products
Published: 2022-02-09
Subjects: Education
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
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 [...]
No evidence for large subglacial source of mercury from the southwestern margin of the Greenland Ice Sheet.
Published: 2022-01-14
Subjects: Education
In the current Matters Arising we present results from verifying control measurements of dissolved mercury (Hg) in glacial meltwater from the Greenland Ice Sheet (GrIS), which significantly challenges the conclusions of the recent publication by Hawkings et al. (2021). By direct measurements of meltwater in the same glacial catchment area, we demonstrate that the input Hg concentration for the [...]
