Long-term monitoring of lakes and fjords on the northern coast of Ellesmere Island, Nunavut, provides information on the effects of climate change on these ecosystems and their seasonal and interannual dynamics. Lake ice cover is a sentinel variable with controlling effects on lake ecosystems, and it is especially sensitive to climate change. This dataset of ice imagery for Ward Hunt Lake (Ward Hunt Island) covers the period 2016-2022 and is a contribution to the NEIGE program (Northern Ellesmere Island in the Global Environment). Weather-resistant time-lapse cameras were installed on metal supports (rods) overlooking the lake in order to observe and document changes in the lake (ice and snow cover, water level) and its watershed (snow, vegetation, ground conditions, wildlife). The dataset has been separated into seasonal or monthly folders to facilitate downloading; note that there was a change of camera model and repositioning in 2017.
