Temperature data from Toolik Lake, Lake N2, Lake E1, Lake E5, and Lake E6, North Slope, Alaska (2010 - 2012)

Lakes are abundant in the terrestrial arctic, extending over about one quarter of the territory. For approximately nine months of the year, the waters of arctic lakes are under ice. Despite the duration of the ice-covered period, few studies have addressed the limnology (biological, chemical, and physical) features of these lakes during winter and how conditions under ice affects summer conditions and vice versa. Our research is being conducted in lakes studied by the Arctic Long Term Ecological Research (ARC LTER). The selected lakes are: Toolik Lake, Lake E1, Lake E5, Lake E6 and Lake N2. The Lakes range in size from 1 to 1500 hectares. We present here time series of water temperatures at several depths obtained from a taut-line mooring in different seasons (summer and winter) across multiple years (summer 2010 until spring 2012).

陆地北极地区湖泊资源丰富，覆盖该区域约四分之一的面积。该区域的湖泊一年中约有九个月处于冰封状态。尽管冰封期漫长，目前鲜有研究探讨这些北极湖泊冬季的湖沼学（limnology）特征——涵盖生物学、化学与物理学维度——以及冰下环境如何影响夏季状况，反之亦然。本研究的调研对象均取自北极长期生态研究（Arctic Long Term Ecological Research, ARC LTER）项目已考察的湖泊，入选的研究湖泊包括图利克湖（Toolik Lake）、E1湖、E5湖、E6湖以及N2湖。这些湖泊的面积介于1至1500公顷之间。本研究公开了2010年夏季至2012年春季多年间，不同季节（夏季与冬季）利用紧绳锚系浮标采集的多深度水温时间序列数据。
