| - | * (1) The calculation only cares about grounded ice, so where it detects that the ice-model has ice that is below the predicted sea-level, it deems the ice to be melted and added to the ocean. The ice may be melted or be part of an ice-shelf eg the Ronne, Ross ice-shelves. This is a feature of the most recent version of the solver. | + | * (1) The version of the ICE-4G (VM2) model for which data are provided is not exactly the version that was employed in the original PMIP project but rather one from which a significant amount of Antarctic ice was simply eliminated (version employed for illustrative purposes in Peltier's paper for the Mt Hood volume of QSR). |

| * The large change between ICE-4G (VM2) and ICE-5G (VM2) is due to the introduction of Art Dyke's margin chronology which had the ice being eliminated from North America earlier than in the original chronology obtained from John Andrews. This meant that more ice had to be removed in order to have the same impact on RSL during the ice-free Holocene interval. | * The large change between ICE-4G (VM2) and ICE-5G (VM2) is due to the introduction of Art Dyke's margin chronology which had the ice being eliminated from North America earlier than in the original chronology obtained from John Andrews.
