Paleo Subglacial Groundwater Exfiltration Time Series, Sediment Permeability = 1×10⁻¹² m², 20 ka to Present

Modeled paleo subglacial groundwater exfiltration rates for each retained study site, computed by forcing the one-dimensional hydromechanical model with the reconstructed ice-thickness time series at a fixed sediment permeability of 1×10⁻¹² m², the second-highest permeability value in the tested range (1×10⁻¹¹ to 1×10⁻¹⁵ m²). Each row gives site number, age (years before present), site coordinates, and exfiltration rate (mm yr⁻¹); positive values indicate exfiltration, negative values indicate infiltration. This deposit contains the posterior-mean, lower 95% CI, and upper 95% CI exfiltration trajectories for this permeability scenario, computed from the corresponding thickness reconstructions.
