Inelastic neutron scattering (INS) measurements of powder D3(7Li)(193Ir)2O6 reveal low energy magnetic excitations with a scattering cross-section that is broad in ∣Q∣ and energy transfer. The magnetic nature of the excitation spectrum is demonstrated by

Marine debris impacts on Hawaiian green sea turtles (Chelonia mydas): High prevalence of hook-and-line fishing gear in strandings

March 29, 2025
Author(s)
Marthe Hoiberg, Jan Borgelt, Philip Mostert, Shawn Murakawa, Summer Martin, Jon Gelman, Jennifer Lynch, Francesca Verones
Stranding data are critical for monitoring threats to sea turtles. By analyzing four decades of green turtle (Chelonia mydas) strandings from the Main Hawaiian Islands, we elucidate temporal and spatial trends. In Hawai'i, fibropapillomatosis (FP) has been
