Repeated surging and rapid retreat of a tidewater glacier in Scotland (Younger Dryas/Greenland Stadial 1)

open access: yesJournal of Quaternary Science, Volume 40, Issue 4, Page 622-633, May 2025.
ABSTRACT This paper presents evidence of glacier surging in the British landform record. We use new high‐resolution multibeam‐echosounder bathymetry data to map the submarine geomorphology of a former tidewater glacier that drained the Skye Icefield, NW Scotland, during the Younger Dryas Stadial (Greenland Stadial 1) ca. 12.9–11.7 ka.

Link Between Stochastic Grid Perturbation and Location Uncertainty Framework

open access: yesJournal of Advances in Modeling Earth Systems, Volume 17, Issue 5, May 2025.
Abstract This paper investigates the relationship between a Stochastic Grid Perturbation (SGP) and Location Uncertainty (LU) in the context of ocean modeling. The LU formulation, which introduces random velocity fluctuations, has shown efficacy in organizing large‐scale flow and replicating long‐term statistical characteristics.
