Stochastic forcing of Pleistocene Ice Sheets

The model is that of Tarasov and Peltier ("Terminating the 100 kyr ice-age cycle", JGR, 102, 21665, 1997) with all parameters and input values barring the above random forcing left unchanged. The data presented here is the flux of fresh water delivered to the oceans by the ice sheets minus the freshwater flux from the unperturbed run (as in Tarasov and Peltier, above).

The ensemble consists of thirty simulations. Column one of each file is the time in thousands of years (negative = before present), column two is the anomalous fresh water flux in Sverdrups. Positive numbers represent a flux to the ocean (corresponding to shrinking ice volume).
