The provided dataset contains surface water samples from lakes and ponds, streams and inflows in the Lucky Lake catchment (lake center coordinates: 72°17'56.1N; 126°10'29.7E) in the south of Kurungnakh Island, Lena River Delta, Russia. It includes concentrations of dissolved organic carbon (DOC) as well as stable isotopes of oxygen (δ¹⁸O) and hydrogen (δD). Samples of this dataset were collected during the Russian-German LENA expeditions in July and August 2013, June to September 2014, and in July 2016. For DOC measurements, we used the Shimadzu TOC-VCPH high-temperature catalytic combustion. Stable isotopes of oxygen (δ¹⁸O) and hydrogen (δD) were measured with a Finnigan MAT Delta-S mass spectrometer at the ISOLAB Isotope Facility AWI Potsdam. ...
