Colored dissolved organic matter (CDOM) absorption measurements of the Lena River in the Lena River Delta, Eastern Siberia, 2013-2016
The datasets present measurements of cDOM absorption in channels of the Lena River in the Lena River Delta during the summer periods from 2013-2016 and the spring periods from 2015-2016. River water samples were collected from Main Channel, Olenekskaya, Tumatskaya, Bikovskaya and Trofimovskaya Chann...

The datasets present measurements of cDOM absorption in channels of the Lena River in the Lena River Delta during the summer periods from 2013-2016 and the spring periods from 2015-2016. River water samples were collected from Main Channel, Olenekskaya, Tumatskaya, Bikovskaya and Trofimovskaya Channels. cDOM is operationally defined by the chosen filter pore size. Samples have been consistently filtrated through 0.7 µm pore size glas fibre filters. cDOM filtrates have been stored in darkness and have been measured after the expedition using the dual-beam Specord200 laboratory spectrometer (Jena Analytik) at the Otto Schmidt Laboratory OSL, Arctic and Antarctic Research Institute, St. Petersburg, Russia. The OSL cDOM protocol (Heim and Roessler, 2016) prescribes 3 Absorbance (A) measurements per sample from UV to 750 nm against ultra-pure water. The absorption coefficient, a, is calculated by a = 2.303A/L, where L is the path length of the cuvette [m], and the factor 2.303 converts log10 to loge.
