“…However, some abrupt climatic events like H1 and YD were not captured clearly in these two records, perhaps due to the special location or sample resolution (Cook et al, ; Q. Wang et al, ). Interestingly, mineralogical and geochemical records from Baoxiu peat in Yunnan Province also provided information on changes in paleoclimate in south‐west China spanning the interval from 32.7 to 11.4 cal ka BP (Huang, Wei, Ma, & Liu, ). Multiproxy records also indicate that cold and dry climate conditions prevailed over the LGM between 23 and 18 cal ka BP.…”

“…Multiproxy records also indicate that cold and dry climate conditions prevailed over the LGM between 23 and 18 cal ka BP. Furthermore, two cold events as indicated by K/Rb ratio could be identified at about 16.1 to 15.0 cal ka BP and 13.0 to 11.8 cal ka BP, roughly corresponding to the H1 and YD, respectively (Huang et al, ). Whereas, pollen diagrams from Erhai Lake and Tiancai Lake demonstrates detailed paleoclimate conditions covering the past 13 cal ka BP (Shen et al, ; X. Y. Xiao, Haberle, Shen, et al, ).…”

High‐resolution paleoclimatic records spanning the past 30 cal ka BP inferred from Qionghai Lake sediments in south‐west China: Insights from geochemical investigations and grain‐size characteristics

There have been few high‐resolution investigations covering the last glacial and Holocene from Sichuan, Yunnan, or south Asia area in the south‐west monsoon domain region. High‐resolution analyses of lake sediments retrieved from Qionghai Lake, Sichuan Province, were conducted using a combination of variables including total organic carbon (TOC) and total nitrogen (TN) concentration, low frequency magnetic susceptibility (χLF), particle size, carbonate content, and δ13C value of organic matter (δ13Corg), to provide a new perspective on the detailed paleoclimate history of south‐west China spanning the past 30 cal ka BP. Our findings suggest that organic matter in the Qionghai Lake was mainly derived from microorganisms, aquatic macrophytes, and terrestrial C3 plants. From 29.1 to 23.2 cal ka BP, low carbonate contents, high median grain size (Md values), and χLF values indicated a warm and wet climate. During the period 23.2 to 15.4 cal ka BP, low χLF, Md values, and high carbonate contents suggested a decrease in temperature and humidity. The cold and dry Last Glacial Maximum (LGM) and Heinrich 1 event (H1) were captured between 21.6 and 19.4 cal ka BP and 17.6 and 15.8 cal ka BP, respectively. During the interval 15.4 to 9.7 cal ka BP, low level of χLF values and Md values, together with relatively high carbonates, demonstrated that a dry climate prevailed in this period. Since 9.7 cal ka BP, the climate was warm and humid in the early to mid‐Holocene and shifted towards cold and dry condition in the late Holocene. A cold and dry period at 8.5 to 8.1 cal ka BP and warm and wet interval at 6.6 to 4.6 cal ka BP were identified, corresponding to the 8.2‐ka cold event and Holocene climatic optimum (HCO), respectively. These climate changes may reflect variations of the intensity of the south‐west summer monsoon, primarily in response to the Northern Hemisphere solar insolation on a millennial scale induced by orbital forcing. The position of the Intertropical Convergence Zone (ITCZ) may add a complementary effect on the evolution of the monsoon strength in the Holocene.

Coastal aquifers are globally subject to considerable stress. The population density is often high in coastal areas, and in addition, the coastal plains often have good agricultural soils demanding irrigation. While a portion of the irrigation can be provided by rivers, local groundwater is also used adding to the water requirement. Many coastal aquifers are large with a slow turnover of the groundwater and recharge is difficult to assess. This review is aimed at giving an overview of the hydrochemistry with an emphasis of giving insight into the groundwater recharge and the sustainability of the groundwater quality. The past climate history has given an imprint of hydrochemistry of especially coastal aquifers.
