Dynamics of ice cover over a far northern fiord: Direct observations of Disraeli Fiord, Canadian High Arctic, by automated camera

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. Ice cover is a sentinel variable with controlling effects on aquatic ecosystems, and it is especially sensitive to climate change. This dataset of ice imagery for Disraeli Fiord 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 fjord in order to observe and document changes in the fjord (ice shelf, sea ice and snow cover) and adjacent terrain (snow, vegetation, ground conditions, wildlife). The dataset has been separated into seasonal folders to facilitate downloading, for the periods: July 2011 to February 2013, July 2015 to September 2016, and July 2018 to September 2020.
