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).
