PALMOD 130k: Marine Palaeoclimate Time Series from 475 Sites

2286 time series of eight palaeoclimate parameters provide a benchmark for climate models spanning the last 130,000 years. Lukas Jonkers from the University of Bremen compiled this synthesis, which includes benthic and planktonic foraminifera isotopes, sea surface temperatures, and sediment composition data. Version 2 offers increased spatial and temporal coverage with recalibrated radiocarbon ages and updated age-depth models.

Use Cases

• Benchmarking transient climate model simulations based on multi-parameter time series spanning 130,000 years.
• Assessing uncertainty in palaeoclimate reconstructions based on the provided age-depth model ensembles and metadata.
• Analyzing global comparability of sea surface temperature proxies based on the single-calibration recalculations for Mg/Ca and U37K′.
• Studying long-term trends in carbon cycle proxies based on benthic foraminifera δ13C time series.

Strengths

• Contains 2286 time series from 475 individual sites, markedly increasing coverage from version 1.
• Includes eight distinct palaeoclimate parameters, such as benthic δ18O (468 series) and sea surface temperature (423 series).
• Provides rich metadata, age-depth model ensembles, and chronologies to support transparent uncertainty assessment.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
