BOREAS Soil Carbon Data with Fire Chronosequence Analysis

This dataset contains physical soil parameters for calculating carbon and nitrogen inventories in the Boreal Ecosystem-Atmosphere Study (BOREAS) Northern Study Area. Measurements were taken discontinuously from August 1993 to July 1996 by the TGB-12 team, focusing on sites with local fire chronosequences to study carbon accumulation in moss regrowth. The data supports estimation of carbon turnover rates using both post-fire accumulation and radiocarbon analysis of soil CO2.

Use Cases

• Calculating carbon and nitrogen inventory in moss and mineral soil layers using soil bulk density and chemistry measurements.
• Determining carbon input and turnover rates by analyzing data from fire chronosequence sites.
• Studying seasonal variations in soil respiration via radiocarbon content of CO2 in the soil atmosphere.
• Modeling carbon accumulation rates in regenerating moss layers after stand-killing fires.

Strengths

• Data collection leverages local fire chronosequences, enabling direct study of carbon accumulation over time.
• Includes radiocarbon content of soil CO2, providing a method for estimating carbon turnover rates.
• Covers a multi-year period from 1993 to 1996 across several tower and auxiliary sites in the NSA.

Limitations

• Exact row count, column names, and dataset size are unknown across all sources.
• Sources conflict on the last updated date: one states 1996-07-21, another states 2026-03-13.
• Data collection was discontinuous over the three-year period.
