Core images of lacustrine sediments and lithological descriptions. (a) Cross-section of a core sample obtained from L. Maruwan (sample Mw5S) and (b) lithological descriptions and uncorrected 14C ages (years BP) of organic carbon. The color data in (a) were obtained with a digital color meter (Konica Minolta, SPAD 503) and revised Standard Soil Color Charts (Oyama and Takehara 2005).
