ABoVE: Seasonal Dissolved Gases and Isotopes in Arctic Alaska Rivers

Description

This dataset provides dissolved carbon dioxide (CO2) and methane (CH4) concentrations alongside their stable and radiocarbon isotopic compositions within the Arctic Sagavanirktok and Kuparuk River watersheds located on the North Slope of Alaska. The data were collected during the spring, fall, and summer seasons in 2022. In field separation of the bulk gaseous components (N2, CO2, and CH4) from the liquid phase was achieved using a degassing membrane contactor. Laboratory isotopic analyses were conducted at the W. M. Keck Carbon Cycle Accelerator Mass Spectrometer facility at UC Irvine. This collection aims to provide insights into the seasonal dynamics of greenhouse gas emissions in these critical Arctic environments, thereby contributing valuable information for climate change research and monitoring programs. The data are provided in comma separated values (CSV) format.

(2015) and (c) lithology percentages per sub-watershed. Sampling locations are marked as follows: a diamond for Atigun River, squares for Sagavanirktok River, and a circle for Kuparuk River. https://daac.ornl.gov/ABOVE/guides/Dissolved_Gases_Alaska_Rivers_Fig1.png
