Wake Atoll: Evaluation of plant biosecurity

Corie Yanger, James D. Jacobi, Stephanie G. Yelenik, Stacie A. Hathaway

2025, Report

Introduced organisms can cause substantial effects across most landscapes. Island ecosystems, especially tropical islands, are at elevated risk from introduced organisms. The risks are even higher for tropical islands with moderate or high levels of transit, yet this can be minimized by application of appropriate biosecurity requirements. In this study,...

Outwash events inhibit vegetation recovery and prolong coastal vulnerability

Jin-Si R. Over, Christopher R. Sherwood

2025, JGR Earth Surface (130)

Overwash, when high ocean water levels and waves flood a coastline, is a common phenomenon that can lead to washover deposits and barrier rollover. Outwash, by contrast, involves seaward flow, often driven by high back-barrier water levels, and can produce washout channels and nearshore deposition. Our observations show that washout...

Waterline responses to climate forcing along the North American West Coast

Marcan Graffin, Rafael Almar, Erwin W.J. Bergsma, Julien Boucharel, Sean Vitousek, Mohsen Taherkhani, Peter Ruggiero

2025, Communications Earth & Environment (6)

Understanding waterline variability at seasonal to interannual timescales is crucial for predicting coastal responses to climate forcing. However, relationships between large-scale climate variability and coastal morphodynamics remain underexplored beyond intensively monitored sites. This study leverages a newly developed 25-year (1997–2022) satellite-derived waterline dataset along the North American West Coast. Our...

Gabor Kereszturi, Pablo Grosse, Melody Whitehead, Marie-Noëlle Guilbaud, Drew T. Downs, Rina Noguchi, Matthieu Kervyn

2025, Communications Earth & Environment (6)

Scoria cones are the most abundant type of volcano in the Solar System. They occur in every tectonic setting and often overlap with human populations, yet our ability to provide complete geochronology within volcanic fields remains limited. Appropriate geochronology underpins the reconstruction of size-frequency distribution and is a key input...

An empirical Green’s function approach for isolating directivity effects in earthquake ground-motion amplitudes

Grace Alexandra Parker, Annemarie S. Baltay, Evan Tyler Hirakawa

2025, Bulletin of the Seismological Society of America (115) 2336-2354

In this study, we apply an empirical Green’s function (eGf) method within a ground‐motion modeling framework to mitigate trade‐offs between source, path, and site effects. Many physical processes contribute to spatial variations in observed ground motions, including earthquake radiation pattern, directivity, variable path attenuation, and site effects. Current nonergodic ground‐motion...
