Two new Miocene limpets (Fissurellidae) from southern California, with notes on other fossil occurrences of the family in northwestern North America [PDF]

open access: yes, 2019
Two new fissurellid limpets (Mollusca: Gastropoda: Fissurellidae), Fissurella? stantoni n. sp. and Scelidotoma aldersoni n. sp., are described from Miocene deposits in southern California. Fissurella? stantoni is described from a single specimen from the

Impacts of Spatial and Temporal Station Availability on Gridded Precipitation Products in Central America

open access: yesEarth and Space Science, Volume 12, Issue 12, December 2025.
Abstract Gridded precipitation data sets have become essential for understanding climate variability and long‐term trends; however, their accuracy and reliability strongly depend on the availability and the spatial and temporal distribution of in situ meteorological observations. Here, we evaluate the performance of four gridded precipitation products:

Ge Detectors and $0\nu\beta\beta$: The Search for Double Beta Decay with Germanium Detectors: Past, Present and Future [PDF]

open access: yes, 2019
High Purity Germanium Detectors have excellent energy resolution; the best among the technologies used in double beta decay. Since neutrino-less double beta decay hinges on the search for a rare peak upon a background continuum, this strength has enabled

The Silicon Isotopic Composition of the North Pacific: Insights From US GEOTRACES Section GP15 and Modeling

open access: yesGlobal Biogeochemical Cycles, Volume 39, Issue 12, December 2025.
Abstract Silicon isotopes within silicic acid, δ30Si, were measured on US GEOTRACES section GP15 from Alaska to Tahiti along 152°W. The distribution of silicic acid, Si(OH)4, exhibited a double Si(OH)4 maximum dominated by a midwater maximum that extended from 55°N latitude to the equator together with a bottom maximum north of 40°N latitude.

UCSB Restoration Register - July 2023

open access: yes, 2023
The Cheadle Center at UCSB manages more than 340 acres of open space between Ellwood Mesa and Goleta Slough, carrying out ecological restoration, research, and education projects at these sites. Characterized by a rich complex of oak woodland, coastal sage scrub, grassland, and wetland ecosystems, the area is known for its relatively high level of ...

DeepGEM‐EGF: A Bayesian Strategy for Joint Estimates of Source‐Time Functions and Empirical Green's Functions

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract An earthquake record is the convolution of source radiation, path propagation and site effects, and instrument response. Isolating the source component requires solving an ill‐posed inverse problem. Whether the instability of inferred source parameters arises from varying properties of the source, or from approximations we introduce in solving
