Abstract

Limnological profile and cytometry of Ward Hunt Lake, located on Ward Hunt Island, Nunavut, Canada. Data were collected during a field campaign in July 2022. The various measurements were carried out for the lake water column, lake ice, soil water (Walker Hill runoff) and the marine environment (Lagoon and Arctic Ocean). The following measurements were taken : chlorophyll-a, coloured dissolved organic matter (CDOM), dissolved organic carbon (DOC), dissolved inorganic carbon (DIC, total nitrogen (TN), total phosphorus (TP), viral and cellular cytometry and stable isotopes of hydrogen and oxygen.
