Geochemical and isotopic analysis results for soil pore water samples collected in Barrow, Alaska during July and September 2013. The dataset covers 17 drainages across interlake and different-aged drained thaw lake basins, with samples taken at three depths per location. Data was produced by the NGEE Arctic project, supported by the Department of Energy, and used in a 2015 publication.
Use Cases
- Modeling carbon fluxes in polygonal tundra by analyzing inorganic carbon isotope ratios across different drainage flow types.
- Investigating permafrost thaw impacts by comparing geochemical data from young, medium, old, and ancient drained lake basins.
- Calibrating soil carbon process representations in models using depth-resolved pore water chemistry from three sample depths.
Strengths
- Data spans 17 distinct watershed drainages, providing spatial variety.
- Samples include three depth profiles per location, offering vertical resolution.
Limitations
- Limited temporal coverage to two months in 2013, lacking seasonal or interannual trends.
- Geographic scope is restricted to the Barrow, Alaska area, limiting pan-Arctic generalization.
