The sand grain and the butterfly. Instability in geodesy and geophysics
, 1997 The problems of convergence of series in celestial mechanics and of certain series in geodesy (Molodensky's series and spherical harmonics) show similar features, involving a curious instability. This is imaginatively expressed as the « butterfly effect»

Optimized J2 Recovery for Multi‐Decadal Geophysical Studies
Geophysical Research LettersThe time history of the Earth's dynamic oblateness, or J2, is a unique climate data record, with its estimation from satellite laser ranging (SLR) tracking data beginning in 1976.

Legacy effects of locally extinct flagship species on protected areas
Frontiers in Ecology and the Environment, EarlyView.Protected areas (PAs) are often established to conserve flagship megafauna so as to mobilize political support and secure sustained conservation investment, with the expectation that flagship‐centered governance will also protect habitat. Despite such efforts, flagship species can experience extirpation, raising a fundamental question: do conservation ...

Geological Journal, EarlyView.New zircon ages reveal that lacustrine sedimentation initiated in the Late Miocene (Messinian), revising earlier Pliocene age assignments. The study results support the interpretation of the northern BFSZ as a broad left‐lateral transtensional shear zone rather than a discrete sinistral fault or simple extensional graben array.

Earth, Planets and SpaceWe present a candidate mean secular variation (SV) model for the 2025.0 $$-$$ - 2030.0 period. The forecasted SV is produced with a data assimilation (DA) system built around a simple frozen-flux model of the core flow and magnetic field near the core ...

Intercomparison of a Regional Climate Model Ensemble for Selected European Catchments
International Journal of Climatology, EarlyView.This study analyzes a regional climate model ensemble for water cycle and water resource research with two models. Results show that ICON generally outperforms TSMP1 simulations, mainly with 2‐m temperature and precipitation. These findings serve as a baseline evaluation that shows how key structural differences influence the model skill.

Journal of Quaternary Science, EarlyView.ABSTRACT Glaciokarst landscapes pose distinctive challenges for cosmogenic dating because meltwater and runoff can be rapidly rerouted into ponors and conduit networks, weakening glacier–river coupling and promoting local sediment storage. We reconstruct glacier retreat and postglacial stabilization on the Snežnik Plateau (SW Slovenia) using in situ ...

Hearing the Serre Invariant of a Compact p‐Adic Analytic Manifold
Mathematische Nachrichten, EarlyView.ABSTRACT Using a previous novel way of defining kernel functions for Laplacian integral operators on a compact p$p$‐adic analytic manifold X$X$, one such operator Δ0s$\Delta _0^s$ with s∈R$s\in \mathbb {R}$ is applied to hearing the Serre invariant i(X)$i(X)$ by showing that a wavelet eigenvalue (with the wavelet having small support) is always ...
