From data to interpretable models: Machine learning for soil moistureforecasting

Soil moisture is critical to agricultural business, ecosystem health, and certain hydrologically driven natural disasters. Monitoring data, though, is prone to instrumental noise, wide ranging extrema, and nonstationary response to rainfall where ground conditions change. Furthermore, existing soil moisture models generally forecast poorly for time periods greater than a few hours. To improve such

Comparing root cohesion estimates from three models at a shallow landslide in the Oregon Coast Range

Although accurate root cohesion model estimates are essential to quantify the effect of vegetation roots on shallow slope stability, few means exist to independently validate such model outputs. One validation approach for cohesion estimates is back-calculation of apparent root cohesion at a landslide site with well-documented failure conditions. The catchment named CB1, near Coos Bay, Oregon, USA

What did they just say? Building a Rosetta stone for geoscience and machine learning

Modern advancements in science and engineering are built upon multidisciplinary projects that bring experts together from different fields. Within their respective disciplines, researchers rely on precise terminology for specific ideas, principles, methods, and theories. Hence, the potential for miscommunication is substantial, especially when common words have been adopted by one (or both) group(

Response of plant, microbial, and soil functions to drought and fire in California

California is experiencing changes in precipitation and wildfire regimes. Longer, hotter fire seasons along with extremes in precipitation are expected to continue. Not only do these disturbances affect the productivity and resilience of ecosystems, they also directly impact human health and wellbeing. Soils hold an immense amount of our terrestrial carbon pool, and the microorganisms and minerals...

2022 Post-Doctoral Fellow - Geophysical Techniques for Off-World Resource Surveys

USGS is partnering with NASA and the Office of the Under Secretary of Defense (OUSD) for Research and Engineering to increase capabilities in off-world resource surveying. We propose to explore the utility and feasibility of geophysical techniques to characterize potential resources in the near subsurface of the Moon and Mars, improving our ability to detect, map, and characterize in situ...
