README Grigoriev data Overview The Grigoriev data collection consists of the following files, which are briefly explained further below.From a relatively large number of files and for clarity, we provide mainly those files which have been directlyused in the generation of figures contained in Machguth et al. (2024). While the use in figurecreation was the main selection criteria, the files have not been truncated to data shown in the figures. The files contain more information than shown in the figures. A few files have been added for completeness althoughnot used to create figures (see below). The data sets provided in this repository are listed in the following. Most of these tables contain relatively raw data. The suggested citations are added in brackets. Please also check Table 1 in Machguth et al. (2024) for potential further references. - 1990_GRG_90_H1-BETA.xlsx (Arkhipov et al., 1996; Thompson et al., 1997)- 1990_GRG_90_H1-CHM.xlsx (Arkhipov et al., 1996; Thompson et al., 1997)- 1990_GRG_90_H1-STRAT.xlsx (Arkhipov et al., 1996; Thompson et al., 1997)- 1990_GRG_90_H2-CHM.xlsx (Arkhipov et al., 1996; Thompson et al., 1997)- 1990_GRG_90_H2-STRAT.xlsx (Arkhipov et al., 1996; Thompson et al., 1997)- 1990_H1-H2_2018_Grigoriev_MI-decadal.xlsx (Arkhipov et al., 1996; Thompson et al., 1997; Machguth et al., 2024)- 2001_GRG_01_S1-EE.xlsx (Arkhipov et al., 2004; Mikhalenko et al., 2005)- 2001_metals.pdf (Usubaliev, 2003)- 2003_GRG03-S1-EE_001.xlsx (Mikhalenko et al., 2005; Kutuzov, 2005)- 2003_GRG03-S2-EE 001.xlsx (Mikhalenko et al., 2005; Kutuzov, 2005)- 2003_pits.xlsx (Mikhalenko et al., 2005; Kutuzov, 2005)- 2003_temperature_density.xlsx (Mikhalenko et al., 2005; Kutuzov, 2005)- 2003_temperature_logger_data.xls (Mikhalenko et al., 2005; Kutuzov, 2005)- 2018_density_stratigraphy_field_and_PSI_by_centimeter.xlsx (Machguth et al., 2024)- 2018_PSI_dating_20230517.xlsx (Eichler et
