在加勒比海南部缺氧的卡里亚科盆地，未受干扰的沉积物的大量钛含量反映了南美洲北部热带地区河流输入和水文循环的变化。钛的季节性解析记录表明，玛雅文明在古典末期的崩溃发生在一个延长的区域干旱期，中间穿插着更严重的多年干旱，集中在大约公元810年、860年和910年。这些新的数据表明，一个世纪的降雨量下降给该地区的资源带来了普遍的压力，然后突然的干旱事件加剧了这种压力，造成了玛雅灭亡的社会压力。
In the anoxic Cariaco Basin of the southern Caribbean, the bulk titanium content of undisturbed sediment reflects variations in riverine input and the hydrological cycle over northern tropical South America. A seasonally resolved record of titanium shows that the collapse of Maya civilization in the Terminal Classic Period occurred during an extended regional dry period, punctuated by more intense multiyear droughts centered at approximately 810, 860, and 910 A.D. These new data suggest that a century-scale decline in rainfall put a general strain on resources in the region, which was then exacerbated by abrupt drought events, contributing to the social stresses that led to the Maya demise.
