Marcacocha palaeoenvironmental proxy dataset (NERC grant NE/J014206/1)

Concentration and accumulation palaeoenvironmental proxy data derived from a 6.3m sedimentary core drilled at Marcacocha, a present-day wetland (formerly a small lake) located at 3355m above sea-level in the Cordillera Oriental of the Peruvian Andes. Multi-proxy analysis of the sediments at decadal to sub-decadal temporal resolution has provided detailed datasets that include sedimentology, palynology, geochemistry, plant macrofossils, diatoms and oribatid mite remains (Chepstow-Lusty et al., 2003, 2007, 2009; Sterken et al., 2006). Select data are presented here relating to the uppermost 1.9m of the sequence (ca. the last 1200 years). The data relate specifically to: Chepstow-Lusty, A., Frogley, M.R., Baker, A.S.

Statement
: In 1993, a series of overlapping sedimentary cores were recovered from the centre of the Marcacocha basin using a 5 cm diameter Livingstone corer. The overall composite length of the sequence was 8.25m, consisting of an upper 50cm horizon of dense peat, underlain by a series of highly organic lake muds (with occasional relatively fine-grained inorganic horizons) to a depth of 6.3m; sediments below this level consisted solely of gravels. The uppermost peats were too fibrous to core, so were sub-sampled continuously from a hand-dug pit at 4cm intervals. A chronology for the sequence was developed using a combination of seven 210-Pb determinations (applying the Constant Rate of Supply model) and six radiocarbon dates from bulk organic carbon (five conventional dates and one AMS), demonstrating that the sequence extended back continuously for the past ca. 4200 years.
