Abstract:

This table contains all high-resolution hyperspectral data accompanying Schouten et al., 2026 in prep. All analytical data were attained from a sediment core taken in Mezzano (42°36'42'' N, 11°46'12'' E, 452 m.a.s.l.); a small 'maar'-lake (0.5 km2; 31 m deep) lake in Lazio, located in Central Italy. The data was collected to get a comprehensive understanding of the interaction between, anoxia, temperature and total trophic productivity in the timeframe 12 ka BP - 15 ka BP. Data were attained in 2019 and 2020. Sediments were collected using a piston corer in 3m segments (UWITEC - style). The sediment cores were cut in 1m pieces and subsampled. The age-depth relationship is established with a Bayesian model blending 7 14C dates, 3 recalibrated bulk 14C dates, and an ash layer. XRF elemental composition was measured on clean surfaces of split cores using an ITRAX XRF core scanner at the University of Bern (5 mm resolution, 20 seconds integration time, Cr X-ray tube at 30 kV and 50 mA). We set elemental counts below a threshold of 100 counts to zero. The first and last 5 mm at the top and bottom of the sediment of each core segment were masked to remove edge effects, and cracks were removed.
