This report documents the acquisition and archiving of a major controlled source and passive seismic imaging project, the Seismogenesis Hikurangi Integrated Research Experiment (SHIRE). The SHIRE project aims to identify and quantify factors controlling the long-term evolution of the Hikurangi margin and the mode of slip along the subduction megathrust. The components of the data volume were acquired in two phases; between October 2017 – April 2018 (SHIRE I) and February–March 2019 (SHIRE II). The...

The energy dialog varies by economic status. Western Europe and the United States suggest there is clean and renewable vs dirty and non-renewable energy, and further that clean energy is cheaper than dirty energy. In this narrative, carbon neutral drives the dialog. Some propose to eliminate coal, oil and even natural gas and nuclear altogether, and suggest that solar, wind and batteries can power the world and address climate change. The IEA just released a...

Understanding climate and human impacts on water storage is critical for sustainable water-resources management. Here we assessed causes of total water storage (TWS) variability from GRACE satellites by comparison with climate forcing, particularly droughts and irrigation water use, in major aquifers in the U.S.. Results show that long-term variability in TWS from 2002 – 2020 tracked by GRACE satellites is dominated by interannual variability in most of the major aquifers. Low TWS trends in the...

The reaction of serpentinized peridotites with CO2-bearing fluids to listvenite (quartz-carbonate rocks) requires massive fluid flux and maintained permeability despite volume increase. Here we investigate listvenites and serpentinites samples from Hole BT1B of the Oman Drilling Project to improve our understanding of the mechanisms and feedbacks of fracturing and vein formation during peridotite carbonation. The samples are characterized by a high abundance of magnesite veins which are often bundled into closely-spaced, parallel sets. Relative cross-cutting...

As our world becomes increasingly globalized in social, economic, and political contexts, U.S. students choose to study abroad to develop their international communication skills, cross-cultural competencies, and second or third languages (NAFSA, 2017). However, an under-researched element of the international education enrollment process is how readable and translated international admissions instructions are, especially for language-minority students whose first language is not English, comprising over 92 million people living in the U.S. (Dillinger, 2017). Examining the...
