英文摘要	We analyzed the delta H-2 composition of n-alkanes isolated from Laguna Zoncho, a small lake in southern Pacific Costa Rica, to reconstruct paleohydrology. Using a core that spans the past 3600 years, we found evidence of dry periods, most notably during the Terminal Classic Drought (TCD; similar to 1200 cal yr BP) and the Little Ice Age (similar to 400 cal yr BP). Previous work at Laguna Zoncho, using bulk sedimentary delta C-13 and geochemical analysis, found that agriculture began to decline during the TCD. Our delta H-2 records confirm the occurrence of arid conditions coincident with the TCD at Laguna Zoncho and show that, despite receiving more than 3000 mm of precipitation per year, this region is susceptible to multidecadal droughts.
