A high-resolution time series of oxygen isotopes from the Kolyma River: Implications for the seasonal dynamics of discharge and basin-scale water use. Geophysical Research Letters 32, L14401, doi:10.1029/2005GL022857.

Investigators performed a stable isotope analysis of rain, snow, the Kolyma River, and a local stream near Cherskii, Siberia from 30 June 2002 through 27 April 2004. As part of the Russian-American Initiative on Shelf-land Environments (RAISE) program, this research was designed to quantify the impacts of disturbance on the seasonal cycle of atmospheric carbon dioxide and the discharge of carbon and nitrogen into the Arctic Ocean in forest and shrubby tundra regions. Monitoring the stable isotopic composition of water runoff from Arctic rivers provides a means to investigate integrated basin-scale changes. Investigators measured river water and precipitation δ¹⁸O and δD to partition the river flow into snow and rain components in the Kolyma River basin (Welp et al. 2005). Data are tab-delimited ASCII text files and are available via FTP. A supplementary graph of the data is also provided in JPEG format.
