The thermal environment of Cascadia Basin [PDF]

open access: yesGeochemistry, Geophysics, Geosystems, 2012
Located adjacent to the NE Pacific convergent boundary, Cascadia Basin has a global impact well beyond its small geographic size. Composed of young oceanic crust formed at the Juan de Fuca Ridge, igneous rocks underlying the basin are partially insulated from cooling of their initial heat of formation by a thick layer of pelagic and turbidite sediments

The 2025 Puerto Rico and Virgin Islands U.S. National Seismic Hazard Model Update: Ground Motion Model Selection and Comparison

open access: yesEarthquake Spectra, Volume 42, Issue 2, May 2026.
We evaluate, select, and describe the ground‐motion models (GMMs) used in the 2025 update of the U.S. National Seismic Hazard Model (NSHM) for Puerto Rico and the U.S. Virgin Islands (PRVI). We identify the most appropriate models that align with GMM selection criteria for use in the PRVI region to improve the accuracy of seismic hazard assessments ...

A stochastic approach to reconstruction of faults in elastic half space [PDF]

open access: yes, 2018
We introduce in this study an algorithm for the imaging of faults and of slip fields on those faults. The physics of this problem are modeled using the equations of linear elasticity.

Evaluation of Earthquake‐Induced Slope Displacements in Greater Vancouver Based on Probabilistic Framework and Using NBCC 2020 and EqDisp Code Platform

open access: yesEarthquake Spectra, Volume 42, Issue 2, May 2026.
Engineers frequently use simplified seismic slope displacement procedures to evaluate the performance of earth structures and natural slopes. Current practices typically adopt Newmark‐type and semi‐empirical seismic displacement prediction models (SDPMs) to estimate the seismic slope displacements (D) based on ground motion intensity measures at a ...

Extent and Duration of the 2003 Cascadia Slow Earthquake [PDF]

open access: yes, 2005
Inversion of continuous GPS measurements from the Pacific Northwest show the 2003 Cascadia slow earthquake to be among the largest of ten transients recognized here. Twelve stations bracketing slow slip indicate transient slip propagated bi-directionally

Water quality in reference watersheds in the United States: A compilation and analysis of small watershed data

open access: yesJournal of Environmental Quality, Volume 55, Issue 3, May/June 2026.
Abstract The natural background contribution from grasslands and forest lands is important to consider in research and management to address the contribution of agricultural, industrial, and urban lands to water quality degradation. To our knowledge, no study has compiled and analyzed reference water quality from small reference grasslands and forests ...

Journey Through Cascadia

open access: yes, 2019
On the West Coast of North America lies the bioregion of Cascadia. Encompassing numerous watersheds, this bioregion is made up of mountains, islands, temperate rainforests, and many more landscapes inherent to its identity. Known for its natural beauty, the region has also been characterized as being environmentally focused with politically left ...

Flux and Isotopic Composition of Sedimentary Carbon Subducting Along the World's Trenches

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract Here we provide comprehensive estimates for the subducted sedimentary flux of inorganic and organic carbon and δ13C at 16 trench segments worldwide. Our calculations provide minimum (incoming sediment), maximum (trench fill) and best estimates (underthrust) of carbon fluxes.

Differential Vulnerability to Ship Strikes Between Day and Night for Blue, Fin, and Humpback Whales Based on Dive and Movement Data From Medium Duration Archival Tags

open access: yesFrontiers in Marine Science, 2019
We examine the dive and movement behavior of blue, fin, and humpback whales along the US West Coast in regions with high ship traffic where ship strikes have been identified as a major concern.
