Lab Report 1: Ice Cores and Climate Change Claudia Casaine September 17, 2023 Materials and Methods: In this second life lab, ice core samples were being collected at a drilling site in Antarctica using an ice drilling rig. After the sample was taken, it was then taken to the lab and studied on the lab bench. The sample was then placed into the Gas Chromatography-Mass Spectrometry or GC-MS to get data on the sample. Results: This table shows how the depth and age of the ice relates to the CO2 concentrations from the drilled ice core. Depth Age (years) CO2 (meters) Before present (ppmv) 0.4 1 400.8 1.8 2 398.6 3.2 3 396.5 4.6 4 393.8 6.0 5 391.6 7.4 6 389.9 8.8 7 387.4 10.2 8 385.6 11.6 9 383.8 13.0 10 381.9 14.4 11 379.8 15.8 12 377.5 17.2 13 375.8 18.6 14 373.2 20.0 15 371.1 21.4 16 369.5 22.8 17 368.3 24.2 18 366.7 25.6 19 363.7 27.0 20 362.6 28.4 21 360.8 29.8 22 358.8 31.2 23 357.1 32.6 24 356.4 34.0 25 355.6 35.4 26 354.4 36.8 27 353.1 38.2 28 351.6
