Colombian Soil Biomarker Data for Paleoclimate Reconstruction

NOAA/WDS Paleoclimatology archives branched GDGT data from modern soils in Colombia. The dataset provides biomarker parameters for paleoclimate studies, with a temporal reference point of 60 calendar years before present. NOAA National Centers for Environmental Information (NCEI) manages this collection, which was last updated in 2010.

Use Cases

• Calibrating the MBT/CBT paleothermometer using branched GDGT concentrations from Colombian soil samples.
• Analyzing spatial variation in soil biomarker parameters across the documented geographic locations in Colombia.
• Reconstructing past mean annual air temperature and soil pH by modeling relationships between branched GDGT indices and modern climate data.

Strengths

• Data is curated and archived by the authoritative NOAA National Centers for Environmental Information (NCEI).
• Provides a specific temporal reference point for calibration at 60 calendar years before present.

Limitations

• Dataset size, row count, and specific parameters are unknown from the provided metadata.
• The data is temporally stale, with a last update recorded in 2010.
