Collaborative Research: Climatic History of the Western Amazon Basin and the Equatorial Andes Since 18k

将利用孢粉学和古湖沼学重建 亚马逊河流域西部的气候历史， 最大冰川期 沉积物芯将从亚马逊河 火山口湖Kumpaka，从一个古老的亚马逊河湖泊， Zancudococha和厄瓜多尔南部的湖泊 安第斯山脉。 放射性碳显示的含化石的亚马逊河暴露 将取样并进行探索。 花粉 和硅藻，并进行分析，以重建 植被和湖泊水位的历史，以测试 假设亚马逊西部的冰川气候是 比全新世气候凉爽而不是干燥。 这个项目很重要，因为它将描绘 这片广袤的热带地区的古气候史 对我们理解气候变化至关重要， 一个几乎不为人知的人 该研究将在 与俄亥俄州的Paul Colinvaux教授合作， 美国国家科学基金会授权号ATM-8709685。

Palynology and paleolimnology will be used to reconstruct the climatic history of the Western Amazon basin since the last glacial maximum. Sediments cores will be raised from Amazonian crater Lake Kumpaka, from an ancient Amazonian riverine lake, Zancudococha, and from the lakes in the southern Ecuadorian Andes. Fossiliferous Amazonian exposures shown by radiocarbon dating to be of glacial age will be sampled and explored. Pollen and diatom and analyses will be undertaken to reconstruct histories of vegetation and lake levels in order to test the hypothesis that glacial climates of the western Amazon were cooler rather than drier than Holocene climates. This project is important because it will delineate the paleoclimate history of this vast tropical region, a region critically important to our understanding of climate change and one virtually unknown. The research will be carried out in collaboration with Professor Paul Colinvaux at Ohio State under NSF grant number ATM-8709685.
