Dynamic time warping to quantify age distortion in firn cores impacted by melt processes
Annals of Glaciology, 2023 As warming intensifies across the Greenland ice sheet, an increasing number of shallow coring and radar studies are targeting the melt-impacted firn column to investigate meltwater processes.

Joint inversion estimate of regional glacial isostatic adjustment in Antarctica considering a lateral varying Earth structure (ESA STSE Project REGINA) [PDF]
, 2017 A major uncertainty in determining the mass balance of the Antarctic ice sheet from measurements of satellite gravimetry, and to a lesser extent satellite altimetry, is the poorly known correction for the ongoing deformation of the solid Earth caused by

Accelerating growth of HFC-227ea (1,1,1,2,3,3,3-heptafluoropropane) in the atmosphere [PDF]
, 2010 We report the first measurements of 1,1,1,2,3,3,3-heptafluoropropane (HFC-227ea), a substitute for ozone depleting compounds, in air samples originating from remote regions of the atmosphere and present evidence for its accelerating growth.

Glacier Change, Concentration, and Elevation Effects in the Karakoram Himalaya, Upper Indus Basin [PDF]
, 2011 In recent decades the consequences of climate change for Himalayan glaciers has become of great concern. Glaciers in much of High Asia appear to be declining, some at globally extreme rates (Ageta 2001;Oerlemanns 2001).

Development of an atmospheric N2O isotopocule model and optimization procedure, and application to source estimation [PDF]
, 2015 This paper presents the development of an atmospheric N2O isotopocule model based on a chemistry-coupled atmospheric general circulation model (ACTM). We also describe a simple method to optimize the model and present its use in estimating the isotopic ...

Near Surface Geophysics, Volume 24, Issue 2, Page 170-186, April 2026.Abstract This study presents a methodological framework for estimating electromagnetic wave velocities in ground‐penetrating radar (GPR) data based exclusively on the analysis of diffractions. The approach integrates diffraction separation using the plane wave destruction algorithm and subsequent velocity refinement through the residual diffraction ...
