Greenland ice core dating

Common global stratigraphic markers are palaeo-events that occur worldwide synchronously, and can allow wiggle-matching between ice cores and other palaeo archives (e.g., marine sediment cores).

As the ice must be melted for analysis, the sample is usually destroyed during analysis. Consistent dating for Antarctic and Greenland ice cores.

Ice cores found at the poles are thought to show 100,000 years of annual snow accumulation.

Ice cores are expensive to collect, house and keep.

They must be stored continuously at a specific temperature.

During snowfall on top of the ice sheets, dust, air, acids, etc.

are added and eventually incorporated into the ice.The reason for this is because uniformitarian scientists view the ice sheet as maintaining equilibrium, about the same height and shape, for a few million years.Thus they view each annual layer as becoming greatly compressed the deeper in the ice sheet.It is further claimed that the very basal ice is 250,000 years old (Dansgaard et al., 1993), or possibly 2.4 million years, back to the time of the original buildup of the ice sheet (Souchez, 1997).This is obviously much too old for the short Biblical time scale. I will show that the interpretation of annual layers is good near the top of the ice cores, but becomes increasingly in error the lower down the core.Oxygen-18 has two more neutrons than oxygen-16 and has a higher mass.
