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).

Investigator collected data from 30 June 2002 through 27 April 2004.
Investigators performed a stable isotope analysis of rain, snow, the Kolyma River, and a local stream near Cherskii, Siberia. They surveyed the following parameters:
Analytical error of 18O and D measurements is 0.1 ‰ and 1.6 ‰, respectively.
