description: terrestrial biomarker
basis: dDprecip reflects Australasian monsoon strength based on modern precipitation isotope data from nearby station (Bali). "At Bali, the closest isotopic monitoring site to Lake Lading, over 80% of precipitation measured from July 2003 to June 2006 fell between October and March (61% during Novembera€“February), coinciding with the southernmost extension of the ITCZ associated with summer intensification of the Australasian monsoon (Figure 1c). The weighted Octo- bera€“March average dDprecip during that time period was 18.72%, similar to the weighted annual (Julya€“June) average of 20.42%, reflecting the strong control of wet season dDprecip on the annual average dDprecip [Kurita et al., 2009]. While large-scale changes in atmospheric circulation could certainly cause the relationship between precipitation amount and dDprecip to vary, these modern observations indicate that dDprecip reflects Australasian monsoon strength."
