(2021). Sampling depths and laboratory numbers are given. \r\nGrain size was measured with a Laser Diffraction Particle Size Analyzer (Beckman Coulter LS 13 320) calculating the percentaged size frequency of 116 classes within a size range of 0.04\u20132000.00 \u00b5m (2% uncertainty). The measurement accuracy was increased by measuring each sample four times in two different concentrations. The grain size distributions were determined using the Mie theory (ISO International Standard 13320, 2009; Fluid RI: 1.33; Sample RI: 1.55; Imaginary RI: 0.1; \u00d6zer et al., 2010; cf. Schulte et al., 2016). \r\nThe colorimetric properties of the sediments were determined as described in e.g. Eckmeier et al. (2013) and Vlaminck et al. (2016) using a Konica Minolta CM-5 spectrophotometer after the samples were homogenized and dried. The L*a*b* values indicate the extinction of light, on a scale from L* 0 (absolute black) to L* 100 (absolute white) and express color as chromaticity coordinates on red-green (a*) and blue-yellow (b*) scales. \r\n\r\nReferences\r\nEckmeier, E., Mavris, C., Krebs, R., Pichler, B., and Egli, M.
