Using a new 65 m long sediment core from the Lena delta apex (Samoylov Island), NE Siberia, this project uses a range of sediment and ground ice properties to help reconstructing the history of the lower Lena River. The analysis includes ( i ) 14C-AMS radiocarbon dating from organic detritus, (ii) grain size composition, (iii) magnetic susceptibility, (iv) XRD (x-ray diffractometry) measurements from the fraction <2 mm, (v) XRF (x-ray fluorescence) measurements from the fraction <2 mm, (vi) TOC (total organic carbon) from bulk sediment, (vii) d13Corg from bulk sediment, (viii) TN (total nitrogen) from bulk sediment, (ix) heavy mineral composition from the fraction 63-125 µm), ( x ) pH from ground ice, (xi) electrical conductivity from ground ice, (xii) the stable water isotope composition (d18O and dD) from ground ice, (xiii) sulfate and chlorine from ground ice, (xiv) DOC (dissolved organic carbon) from ground ice. ...
