The ASTE‐BGC Data‐Assimilative Regional Ocean Biogeochemical Model

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 8, August 2026.
Abstract We present a data‐assimilative regional ocean biogeochemical model, ASTE‐BGC, which simulates the physical and biogeochemical state of the North Atlantic Ocean from 2002 to 2017. Model physics are provided by a physical state estimate (ASTE), which assimilates O(109) in situ and satellite‐based observations over the model domain and time ...

Terrain forms and spatial variability of soil properties in an area cultivatedwith citrus Formas do relevo e variabilidade espacial de propriedades do solo em área cultivada com citros

Engenharia Agrícola, 2011
The technique of precision agriculture and soil-landscape allows delimiting areas for localized management, allowing a localized application of agricultural inputs and thereby may contribute to preservation of natural resources.

The Effects of Late Pleistocene Sea‐Level Fluctuations and Sediment Transport Processes on the Sequestration of Fresh and Brackish Water in Continental Shelf Environments

Water Resources Research, Volume 62, Issue 8, August 2026.
Abstract Offshore fresh groundwater (OFG) is regarded as a significant, albeit typically non‐renewable, unconventional water resource stored within continental shelves. Many models of offshore freshwater emplacement use present‐day stratigraphy while applying Pleistocene sea‐level fluctuations.

Spatio-temporal variability of erosivity in Mato Grosso, Brazil

Revista Ambiente & Água, 2018
The impact of rainfall on surfaces lacking vegetal cover can dissociate soil particles, thereby initiating the erosion process. This is known as rainfall erosivity and is expressed by the R factor in the Universal Soil Loss Equation.

From Resistivity to Hydraulic Properties: Calibrating a Groundwater Flow Model by Integrating Airborne Electromagnetic and Borehole Data Into a Probabilistic Multi‐Texture Framework

Water Resources Research, Volume 62, Issue 8, August 2026.
Abstract Airborne electromagnetic (AEM) surveys offer rapid, cost‐effective subsurface imaging, yet converting their electrical resistivity (ER) models into physically meaningful hydraulic property fields for groundwater models remains a challenge. We develop and demonstrate a data‐driven workflow for an unconsolidated sedimentary aquifer system in ...

CyberGeoAI For Intelligent Spatial Decision Support

Transactions in GIS, Volume 30, Issue 5, August 2026.
ABSTRACT The evolution of spatial decision support systems (SDSS) is being rapidly shaped by the integration of Cyberinfrastructure (CI) and Geospatial Artificial Intelligence (GeoAI), collectively referred to as CyberGeoAI. The rise of big data, complex decision environments, and computing power gives opportunities for advanced tool development to ...

Spatial patterns and GIS habitat modelling of Solea solea, Pleuronectes flesus and Limanda limanda fish larvae in the eastern English Channel during the spring

Scientia Marina, 2006
The spring distribution of larval fish stages of flatfishes in the Dover Strait (eastern English Channel) was studied in 1995 and 1999. Fish larvae were identified and sorted according to developmental stages in order to study their ontogenic ...

Invisible Ship Tracks Produce Mean‐State Cloud Microphysics Perturbation in Tropical Trade Cumulus

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Aerosol effects in cumulus‐topped boundary layers remain relatively unconstrained and drive uncertainty in climate modeling. We assess the impacts of shipping aerosol on trade cumulus, combining satellite retrievals and large eddy simulations (LES).

Crop-management factor calculation using weights of spatio-temporal distribution of rainfall erosivity

Soil and Water Research, 2018
Inappropriate integration of USLE or RUSLE equations with GIS tools and Remote Sensing (RS) data caused many simplifications and distortions of their original principles. Many methods of C and R factor estimation were developed due to the lack of optimal
