Extended Data Fig. 5: Greyscale data in relation sedimentological changes at the site.
From: Sensitivity of Holocene East Antarctic productivity to subdecadal variability set by sea ice
Greyscale data compared to various sedimentological proxies of the core. (a) GRA Bulk Density (b) Natural Gamma Radiation (NGR) (c) XRF peak area of silicon (d) XRF peak area of titanium (e) XRF peak area of silicon/titanium ratio used to indicate long-term changes in biological productivity (f) Greyscale curve from the CT images. XRF, GRA Bulk Density, and Greyscale interpolated to 5 cm. Black curves indicate a robust LOESS smoothing using 2% of the data points for all data sets. GRA Bulk Density and NGR data from ref. 17.
