A standardized EGRIP density profile, true depth and ice-equivalent depth ...

We here report measured densities from a combination of records from the EastGRIP ice-core site. The data come from a trench and two ice cores: the shallow EGRIP-S6 core and the deep main core of the project. Based on these data, we parametrize the density as a function of depth, allowing us to prov...

Description
Summary:We here report measured densities from a combination of records from the EastGRIP ice-core site. The data come from a trench and two ice cores: the shallow EGRIP-S6 core and the deep main core of the project. Based on these data, we parametrize the density as a function of depth, allowing us to provide a standard transfer function between true depth and ice-equivalent depth which is consistent with the EGRIP density measurements. EGRIP density data are only available to 117 m depth, at which depth the density is about 900 kg/m^3 and the difference between true depth and ice-equivalent depth is about 22 m. The density and overburden profiles have been extended below this depth and all the way to 1200 m in order to provide a convenient, continuous and (mostly) smooth transfer function between true depth and ice-equivalent depth. See PDF file provided under 'Documentation' for full description of data and parametrization. ...
