2023, Book chapter, River basin management: Under a changing climate
A multiscale perspective is essential for conservation planning of riverine fishes. Coarse-scale habitat (e.g., basis) can influence both finer-scale habitat characteristics (e.g., reaches and microhabitat) and associated species distributions. Finer-scale management and habitat rehabilitation efforts can fail without the consideration of coarser-scale constraints. We provide a conceptual hierarchical framework for...

Using machine learning techniques with incomplete polarity datasets to improve earthquake focal mechanism determination
Robert Skoumal, David R. Shelly, Jeanne L. Hardebeck
2023, Seismological Research Letters (94) 294-304
Earthquake focal mechanisms are traditionally produced using P‐wave first‐motion polarities and commonly require well‐recorded seismicity. A recent approach that is less dependent on high signal‐to‐noise exploits similar waveforms to produce relative polarity measurements between earthquake pairs. Utilizing these relative polarity measurements, it is possible...
