Stable isotope and gas properties of two climatically contrasting (Pleistocene and Holocene) ice wedges from Cape Mamontov Klyk, Laptev Sea, northern Siberia
This paper presents and discusses the texture, fabric, water stable isotopes (δ18O, δD) and gas properties (total gas content, O2, N2, Ar, CO2, and CH4 mixing ratios) of two climatically contrasted (Holocene vs. Pleistocene) ice wedges (IW-26 and IW-28) from Cape Mamontov Klyk, Laptev Sea, in northe...
