Abstract:
Presented are analytical data from lacustrine sediment cores, retrieved from Lake Nam Co (Tibetan Plateau). The sediment core is a composite of one gravity core, taken with a Rumohr-Meischner gravity corer (63 mm diameter) and a piston core, retrieved using an uwitec piston coring system (http://www.uwitec.at; 90 mm diameter). The composite core labelled <NC 08/01> comprises a total length of 10.378 m. The cores were obtained at N 30.737417, E 090.790333 at a water depth of 93 m on 2008-09-15. The purpose of obtaining this sediment core was to establish a high-resolution record of climate (monsoonal) and environmental change using multiple proxy data. The dataset comprises analytical data based on sedimentological, inorganic geochemical, mineralogical and isotope-geochemical methods. Specifically: sediment water content & density; magnetic susceptibility; particel size data; quantitative inorganic geochemical data (ICP-OES aqua regia and HCL digestions); semi-quantitative XRF elemental data; carbon, nitrogen, sulfur contents; qualitative mineralogical data; bulk sediment stable carbon and oxygen isotope data.

Comment:
Total carbon (TC), total organic carbon (TOC), total nitrogen (TN), and total sulfur (TS) were measured with a CNS elemental analyzer (Vario El, Elementar Analysensysteme GmbH). Total inorganic carbon (TIC) content was calculated by subtracting TOC from TC. 10 to 20 mg dry and ground sediment of each sample was used for the measurement. In total 10 triplicate measurements were carried out to quantify the analytical error.
