The Spatiotemporal Evolution of Creep on the Southern San Andreas Fault Between 2015–2021

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract The Southern San Andreas fault (SSAF) in the Coachella Valley experiences shallow creep and slow slip events (SSE), which re‐distribute stresses in the seismogenic zone and affect the potential of future earthquakes. Although average creep rates are relatively well‐constrained, untangling the details of spatiotemporal variation in creep along ...

Variogram analysis of stochastic processes

open access: yesЖурнал Белорусского государственного университета: Математика, информатика, 2018
Properties of the semivariogram of an intrinsically stationary continuous-time random process with finite second moment are investigated. A necessary and sufficient conditions for a continuous function to be semivariogram are found.

A Classification for a Geostatistical Index of Spatial Dependence

open access: yesRevista Brasileira de Ciência do Solo
: In geostatistical studies, spatial dependence can generally be described by means of the semivariogram or, in complementary form, with a single index followed by its categorization to classify the degree of such dependence.

Interseismic Strain Accumulation and Partitioning in Hispaniola From GNSS and InSAR

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract We combine GNSS and InSAR observations to constrain the spatial distribution of strain across the northeastern Caribbean plate boundary, focusing on Hispaniola, to investigate strain partitioning and fault slip rates in an actively deforming tectonic setting with significant seismic hazard.

Uncertainty in Upscaling In Situ Soil Moisture Observations to Multiscale Pixel Estimations with Kriging at the Field Level

open access: yesISPRS International Journal of Geo-Information, 2018
Upscaling in situ soil moisture observations (ISMO) to multiscale pixel estimations with kriging is a key step in the comprehensive usage of ISMO and remote sensing (RS) soil moisture data. Scale effects occur and introduce uncertainties during upscaling

Spatial and Temporal Stability of Weed Patches in Cereal Fields under Direct Drilling and Harrow Tillage

open access: yesAgronomy, 2020
The adoption of conservation agriculture (CA) techniques by farmers is changing the dynamics of weed communities in cereal fields and so potentially their spatial distribution.

Surficial Substrate Complexity of the Central Gulf of Maine as Observed Through Video Observation During a Fisheries Survey

open access: yesMarine Ecology, Volume 47, Issue 5, September/October 2026.
ABSTRACT The Gulf of Maine is a geologically complex environment that supports a high diversity of plankton, invertebrates, and fish, including commercially important species. Its substrate heterogeneity is well known though existing high‐resolution substrate data are limited, hindering effective fisheries management.

Study of the spatial variability of moisture and compaction in soils with different plant covers

open access: yesAgronomía Colombiana, 2016
Soil is a dynamic system, with physical, chemical and biological properties that have high spatial variability, making necessary to use innovative methodologies to study this variability.

Development and Evaluation of an Urban Atmospheric Inverse Modeling Framework for the Washington, DC and Baltimore, MD Metropolitan Area: Initial Results From an Inert Tracer Case Study

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 16, 28 August 2026.
Abstract Accurate quantification of hazardous material releases in cities is critical for emergency managers aiming to mitigate health impacts and mortality in the population. Here, a study on the development and evaluation of a high‐resolution (1‐km, 1‐hr) urban‐scale atmospheric inverse modeling system for the Washington, DC, and Baltimore, MD ...
