Also working with lake sediment data were Zhang et al. (2004), who developed a salinity history of Qinghai Lake (the largest inland saline lake in China) for the period AD 1100-2000 using ostracod shell-length information derived from a 114-cm sediment core and a relationship between ostracod shell-length and salinity that was developed by Yin et al. (2001) from data gathered from fifty lakes of different salinities scattered across the Tibetan Plateau. They report that "low salinity during 1160-1290 AD showed the humid climate condition [of] the Medieval Warm Period in this area, while the high salinity during 1410-1540 AD, 1610-1670 AD and 1770-1850 AD [corresponded with] the three cold pulses of the Little Ice Age with a dry climate condition," where the evidence for the occurrence of these warm and cold intervals comes from the climate change studies of Yao et al. (1990) and Wang (2001).
