Wavefield-reconstruction-based full waveform inversion on noisy data in seismic exploration

Frontiers in Earth Science
Full waveform inversion (FWI) is commonly used in seismic exploration to calculate parameters of the medium, such as velocity, from the signal as it passes through the medium.

Challenges and Opportunities in Multi‐Method Integrated Geophysical Prospection of Buried Building Remains at the Sanctuary of Olympia

Archaeological Prospection, Volume 33, Issue 3, Page 731-744, July/September 2026.
ABSTRACT Ancient Olympia was one of the most important sanctuaries and the venue for the Olympic Games in Greek and Roman times. Its remains are located in the Olympia Terrace (Peloponnese, Greece) at the present‐day confluence of the rivers Alpheios and Kladeos at the base of Mount Kronos.

The CRESCENT Generation 0 Cascadia Community Velocity Model: Constraints From the Joint Inversion of Teleseismic Receiver Functions and Ambient Noise Data

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract The Cascadia subduction zone can produce M9+ megathrust and M6.5+ intraplate earthquakes, motivating the need for a detailed 3‐D model of seismic properties at scales relevant to regional geology, basins, and infrastructure. To construct the Generation 0 Cascadia Region Earthquake Science Center Community Velocity Model (CRESCENT CVM), we ...

Including Fitness and Health Proxies Can Alter Our Understanding of Habitat Selection

Ecology Letters, Volume 29, Issue 7, July 2026.
Habitat selection studies rarely account for fitness or health, yet our simulations show that ignoring such information can misguide management actions. Using three case studies, we demonstrate how easily health and fitness proxies can be integrated into habitat selection analyses and the added insights they provide, such as links between habitat ...
