Statement

Methodology:

We undertook multi-proxy analyses (diatom, grain size, geochemical and sedimentological) on a 77 cm-long sediment record extracted from the flat-bottomed eastern basin depocentre of Kiteschsee Lake and compared data obtained with published lake records from the Fildes Peninsula. A chronology for the Kiteschsee Lake sediment record was based on two aquatic moss ages, six bulk sediment AMS radiocarbon ages, and four tephra correlation ages and established using Bayesian age-depth modelling in BACON v. 2.5 in R (Blaauw and Christen, 2011).

Data collection:

High resolution X-ray fluorescence (ITRAX) core scanning (XRF-CS) of bulk sediment was performed at contiguous 0.02 cm (200 micrometers) intervals following standard procedures on the ITRAX-XRF machine at Aberystwyth University.

Data quality:

To account for downcore variations in count rate, density, water and organic content, XRF-CS data are presented as relative changes in percentages of the Total Scatter Normalised ratio sum (%TSN), which is equivalent to the %cps sum and as natural log ratios and centred log ratios (clr). Log ratios have been shown to produce similar downcore patterns to more traditional, and fully quantitative, Wavelength Dispersive Spectroscopy, WDS-XRF, dry subsample analysis. Data were filtered to remove the small number of downcore spectra with kcps less than mean minus two-SD, caused mainly by small gaps in the core, and MSE values greater than mean plus four-SD as this represents a poor fit of the measured to theoretical energy spectra.
