Method synopsis

Systematic collection of snowpack samples across elevation gradients using snow pits dug at 10 cm increments to obtain SWE-weighted composite isotopic signatures representative of accumulated snowpack.

Synthesized from method descriptions across 6 papers using this protocol.

Procedure from a recent peer-reviewed implementation

Steps below were extracted from the most recent peer-reviewed implementation of this protocol in the corpus — Stream water sourcing from high-elevation snowpack inferred from stable isotopes of water: a novel application of d-excess values (2024), Hydrology and Earth System Sciences. The protocol was originally introduced by The Snowmelt Niche Differentiates Three Microbial Life Strategies That Influence Soil Nitrogen Availability During and After Winter (2020), Frontiers in Microbiology. doi 10.3389/fmicb.2020.00871. Implementations in other papers (listed below) may differ.

1. Snowpack sampling across elevation gradient
   Snow pits were dug at flat areas with samples collected in duplicate at 10 cm depth increments to tabulate snow density, temperature, and stable isotope ratios. Snow isotopic content represents the SWE-weighted composite value across the entire snow column.
   Quantities: 53 snow pits across 1324m elevation gradient from 2347 to 3671m elevationDuration: Sampling generally took place between early February and late May, with 80% of samples taken ±30 d from 1 AprilConditions: Peak snow accumulation timing, assumed to be timing of peak SWE
   Equipment: shovels for digging snow pits, sampling containers, thermometer, density measurement tools
