Organic material, sediment and ice characteristics of two permafrost cores from Yukechi Alas, Central Yakutia

These data are laboratory results for carbon characteristics (TOC, TC, TN, C/N ratio, stable carbon isotope ratio, radiocarbon ages from bulk organic material), sediment characteristics (mass specific magnetic susceptibility (4.65 kHz & 0.465 kHz), grain size measurements < 1 mm) and ice characteristics (sample mass (wet), sample mass (dry), absolute ice content, stable oxygen and hydrogen isotope ratios of pore ice, pH and conductivity of pore ice).Two cores were analyzed: Yedoma core YED1 N 61.75967° / E 130.47438°;h = 218 m asltotal length: 22,35 m (recovery 21,13 m)ice wedge included from ~7,14 to ~9,5 m Alas core Alas1drilled in the drained part of a thermokarst lake basinN 61.76490° / E 130.46503°total length: 19,80 m (recovery 11,14 m)unfrozen conditions from ~1,6 to ~7,5 m Both cores were drilled in March 2015 from dry land surface in a joint expedition of the ERC PETA-Carb poject and the DFG project UL426/1-1 "Short and long-term thermokarst dynamics due to climate changes and human impacts in Central Yakutia, Siberia (2013-2016)". The sample names are compiled as [campaign]-[core] [drive] [depth (top)] - [depth (bottom)]. Age calibration was done with Calib7.10. Grain size percentages were calculated using GRADISTAT (Blott and Pye, 2001). Missing carbon isotope and C/N ratio values are a result of carbon and/or nitrogen contents below detection limit (0.1 wt%).Missing ice characteristics values are a result of dry and/or fine material obstructing the pore ice/water extraction.
