Quantitative proxy extraction and environmental time-series analysis
Multivariate sediment records contain mixtures of climate, catchment and depositional signals. Independent component analysis, spectral methods and multiproxy comparisons can help separate those signals and test their temporal structure.
Lake Hazar ICA
Independent component analysis extracts climate-sensitive signals from μXRF records.
Lake Van ICA
A 250 kyr record is decomposed into statistically independent temperature- and precipitation-related components.
Spectral analysis
Lomb–Scargle analysis evaluates orbital and shorter-period cyclicity in Lake Van sediments.
Multiproxy synthesis
The Seki Basin study integrates pollen, μXRF and carbon records with human-impact evidence.
