About 20% of the Arctic Coastal Plain is covered by thaw lakes developed overice-rich permafrost. A much larger proportion of this landscape is also scarred bydrained thaw-lake basins, which become sites for the accumulation of organic carbon aspeat deposits. For this interdisciplinary study of thaw lakes and thaw-lakebasins, the Principal Investigators will interview Inupiat Elders from the villages of Barrow and Atqasuk. The objective is to obtain first-hand accounts of lake drainage events, locate these basins, and, using these oral traditions, establish the date of lake drainage occurrence well before the earliest air photographs. This project is intellectually meritorious in that the results will add significantly to our understanding of the basic processes responsible for these important elements of the northern Alaskan landscape. Broader impacts include accessing traditional knowledge of local Elders in Barrow and Atqasuk, who have primary and secondary information on recent lake drainage and flooding events. This project fulfills SGER criteria of having a severe urgency with regard to availability of, or access to data, in that the Elders of the North Slope possess unique ecological and scientific knowledge which is disappearing rapidly.

大约20%的北极沿海平原被融化的湖泊覆盖，形成了富含冰的永久冻土层。这一景观的很大一部分也因融化湖盆地的排水而伤痕累累，这些盆地成为有机碳沉积物积累的场所。对于这项关于融湖和融湖盆地的跨学科研究，首席研究员将采访巴罗和阿特卡苏克村庄的因纽特长老。目的是获得湖泊排水事件的第一手资料，定位这些盆地，并利用这些口头传统，早在最早的航空照片之前确定湖泊排水发生的日期。该项目在智力上是有价值的，因为其结果将极大地加深我们对阿拉斯加北部景观这些重要元素的基本过程的理解。更广泛的影响包括获取巴罗和阿特卡苏克当地长老的传统知识，他们拥有有关最近湖泊排水和洪水事件的主要和次要信息。该项目符合 SGER 标准，即在数据的可用性或获取方面具有严重紧迫性，因为北坡长者拥有独特的生态和科学知识，但这些知识正在迅速消失。
