Dynamic modeling of coastal compound flooding hazards due to tides, extratropical storms, waves, and sea-level rise: a case study in the Salish Sea, Washington (USA)
Published: 2023-03-13
Subjects: Education
The Puget Sound Coastal Storm Modeling System (PS-CoSMoS) is a tool designed to dynamically downscale future climate scenarios (i.e., projected changes in wind and pressure fields and tem-perature) to compute regional water levels, waves, and compound flooding over large geographic areas (100s of kilometers) at high spatial resolutions (1 m) pertinent to coastal hazard assessments and planning.

Equality, Diversity and Inclusivity: Report of a survey of its members and others by the Mineralogical Society of the UK and Ireland
Published: 2023-03-04
Subjects: Education, Physical Sciences and Mathematics
During its November 2020 Council meeting, the Mineralogical Society decided to conduct a survey of its members and others to assess views on equality, diversity and inclusivity (EDI) in terms of the experience of individuals. Although many organizations, including Learned Societies, have developed policy on the basis of surveys, meetings at executive and other committee level, and through the [...]
Investigation of Capillary Pressure Effects on Well Cleanup after Hydraulic Fracturing
Published: 2023-02-20
Subjects: Education, Engineering
Nowadays hydraulic fracturing is becoming the most popular practice for low permeability reservoirs. While in some cases fractured wells show superior productivity than non-fractured wells, in other cases the effective fracture length which is used to channel gas and oil from reservoir to wellbore, is much shorter than the propped fracture length, thus leading to a lower-than-expected production [...]
SEDucate: Sedimentary Log Exercises for an Active Learning Environment
Published: 2023-01-26
Subjects: Education
Active learning in education has been shown to improve a students’ learning experience in higher education by focusing on a student-centered learning environment; however, development of realistic activities that replicate the complexity of real-world examples without being too complex for the novice learner is often challenging. Here we present SEDucate, a GIS plugin to build realistic [...]
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: 2022-07-13
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
Published: 2022-06-22
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 [...]
