3D Model of the Shallow Crustal Density Distribution of the Krafla Volcanic System in Iceland
Journal of Geophysical Research: Solid Earth, Volume 130, Issue 7, July 2025.Abstract Krafla volcano, located in Iceland's North Volcanic Zone, has been extensively studied using static gravity surveys since 1975. This study integrates measurements acquired between 2022 and 2023 with legacy data to produce a new gravity map of the area. We produce gravity gradient maps to delineate shallow subsurface density features and invert

JAWRA Journal of the American Water Resources Association, Volume 61, Issue 3, June 2025.ABSTRACT Farm ponds are a common feature of agricultural landscapes for irrigation of crops. Yet small water bodies have been ignored as reservoirs and carbon balance features despite their ubiquity in the global landscape. These ponds contain surface water from precipitation and runoff, but in South Georgia, USA, groundwater supplementation is ...

A univariate quasi-multiquadric interpolationwith better smoothness
Computers & Mathematics with Applications, 2004 A univariate quasi-interpolation scheme is proposed which is derivative-free and efficient. Since it is a quasi-interpolation method, no linear systems need to be solved for computing the required coefficients; this makes it also suitable for smoothing.
