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. Hyperspectral data were derived from scans made with Specim PFD-CL-65-V10E line scan camera, which measures the absorbance of light in the visible and near-infrared spectrum (400-1000nm; 1nm spectral resolution; 8 Hz; 120 seconds exposure). Index values of RABD667 (total chlorophyll a) and RABD844 (total bacteriochlorophyll a) were calibrated against pigment concentration values using linear regression to discrete samples, whereby pigment concentrations were measured using a UV-VIS Spectrophotometer Shimadzu UV-1800. RABD619 is a proxy for phycocyanin, a pigment produced by cyanobacteria.
