Time series of water temperature, specific conductance, and oxygen from Lake Toolik, North Slope, Alaska, 2013-2014.
Lakes are especially numerous in the arctic region, 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,...
