Method synopsis

Numerical modeling approach combining energy-mass balance calculations with ice-flow modeling to reconstruct past glacier extents and determine paleoclimate conditions. Uses digital elevation models and climate parameters to simulate glacier behavior.

Procedure from a recent peer-reviewed implementation

Steps below were extracted from the most recent peer-reviewed implementation of this protocol in the corpus — Latest Pleistocene glacial chronology and paleoclimate reconstruction for the East River watershed, Colorado, USA (2024), Quaternary Research. Implementations in other papers (listed below) may differ.

1. Glacier modeling
   Used coupled energy–mass balance and ice-flow models with monthly climate parameters. Applied PRISM mean monthly precipitation and temperature (1971–2000 CE) as inputs to energy–mass balance model. Ice-flow model uses finite-element approach with shallow-ice approximation to calculate ice thickness and extent.
   Quantities: Monthly climate data from 1971–2000 CE, depth-averaged bulk density of 1.9 g cm⁻³Duration: Model simulations run until steady-state glacier reachedConditions: Computational modeling
   Equipment: digital elevation model, PRISM climate data
