Global Lake-Level Variations from 18,000 to 0 Years Ago: A Palaeoclimatic Analysis

Lake-Level fluctuations have been recognized as an indicator of climate change on time scales ranging from 10 to 10^6 years. This is especially true of hydrologically-closed basins in which water-level fluctuations are not damped by varying rates of surface outflow. Evidence of past fluctuations occurs in a wide variety of forms, ranging from old shorelines and lake-side archaeological sites to geochemical, mineralogical, isotopic and palaeoecological analyses of sediment cores.

背景概述

该数据集聚焦于过去18,000年全球湖泊水位变化，作为古气候分析的关键指标。它特别关注封闭水文盆地的水位波动，因为这些波动不受地表流出速率的影响，能更准确地反映气候变化。数据集涵盖多种证据类型，包括古海岸线、考古遗址以及沉积物岩心的多学科分析，为研究长期气候演变提供了综合数据。
