Short summary

This study used mass spectrometry imaging (MSI) to detect spatial patterns of biomarkers used for sea surface temperature (SST) reconstructions. The observed proxy heterogeneity was bigger than expected within layered marine sediments. The data was used to estimate the climate signal content of individual MSI based reconstructions. The results can be used to inform sampling decisions or to derive uncertainty estimates for high-resolution SST reconstructions and climate variability estimates.
