The Amargosa: A river at risk

The Amargosa River, which runs mostly underground over the course of its 180-mile stretch, is a lifeline for the unique and rare species that exist in the fragile habitats where it surfaces. The river stretches through southern Nevada, the Mojave Desert in southern California and winds into Death Valley, regions subjected to a “megadrought” for much of the last 20 years. Due to its proximity to a nuclear test site and a proposed nuclear waste

AI Applied Geoscience Hackathon results released

Seven teams of geoscientists and data scientists collaborated and competed 22 March–9 April SEG Advanced Modeling project (SEAM) OpenACC Organization, and NVIDIA co-hosted the SEAM AI Applied Geoscience GPU Hackathon from 22 March–9 April. Seven teams of geoscientists and data scientists collaborated and competed in developing solutions for two hard challenges in the use of machine learning and artificial intelligence to understand large seismic datasets. The first challenge involved a six-way “facies classification” of pixels

Record-breaking hole drilled off coast of Japan

On 14 May 2021, a team of scientists dug the deepest ocean hole ever, reaching a depth of nearly five miles below the ocean’s surface. The team of researchers penetrated the surface all the way to the bottom of the Japan trench in the western Pacific Ocean. In addition, researchers extracted a 120-foot sediment core using a Giant Piston Corer (GPC) making it the deepest sub-level sample ever recovered. In 2011, the nearby region was

New research offers theory for origin of subduction zone

In 2018, a group of scientists boarded the research vessel Marcus Langseth to study the Puysegur margin. This voyage, part of the South Island Subduction Initiation Experiment, set out to find answers to how subduction zones form. Since subduction zones are by nature destructive, they are difficult to study. The Puysegur margin, a fairly young subduction zone, has not yet matured enough to have lost its history, making it an ideal location to study the

Mars Shifting Climate Suggested by Dune Fields in Gale Crater

The Perseverance rover on Mars has received much of the focus in recent planetary news. Yet, data from the Curiosity land rover is still being analyzed to help researchers gain insight into the planet’s ancient atmosphere and potential habitability. An international team at Imperial College London recently released a study, which examines the dune fields around Gale Crater and offers possible explanations for the surface conditions on Mars. Looking to the rock record of the

Five questions with Dr. Douglas Oldenburg for GWB

Improving Water Security in Mon State, Myanmar via Geophysical Capacity Building How did this GWB project come about? Our GWB project was completed in mid-2020. Serenity (Ren) Fan was the catalyst for this project. In 2018 Ren, who I later hired as a project manager, worked in Myanmar with the Mon Department of Rural Development (MDRD). This was made possible with the support of Canadian International Development Organization Cuso International (equivalent of Peace Corps). Over
