Ensemble of Neural Networks Utilizing Seismic Attributes for Rock‐Property Inversion With Uncertainty Estimation

open access: yesEarth and Space Science, Volume 11, Issue 6, June 2024.
Abstract Seismic inversion holds significant importance across various domains of geoscience and engineering, including the characterization of energy resource reservoirs, the assessment of polluted sites, and CO2 storage. It is a process of estimating rock properties from seismic data that is inherently uncertain, nonlinear, non‐unique, and highly ...

Provisioning services decline for both people and Critically Endangered wildlife in a rainforest transformation landscape

open access: yesPeople and Nature, Volume 6, Issue 2, Page 627-645, April 2024.
Abstract The loss and degradation of forests and other ecosystems worldwide threaten both global biodiversity and the livelihoods of people who use natural resources. Understanding how natural resource use impacts landscape provisioning services for both people and wildlife is thus critical for designing comprehensive resource management strategies. We

Historical tree phenology data reveal the seasonal rhythms of the Congo Basin rainforest

open access: yesPlant-Environment Interactions, Volume 5, Issue 2, April 2024.
Ground‐based long‐term (1937–1956) phenological observations of tropical tree species in the central Congo Basin are recovered and allow for the analysis of species‐specific phenological patterns. The onset of leaf phenophases in deciduous species was triggered by drought and light availability for a subset of species and showed a species‐specific ...
