Tasiujarjuaq

In Nunavik, Tasiujarjuaq may refer to Hudson Bay instead.

Tasiujarjuaq (Inuktitut syllabics: ᑕᓯᐅᔭᕐᔪᐊᖅ,^[1] meaning "big lake-like lake") formerly Soper Lake^[2] is a large, irregularly shaped lake in the Qikiqtaaluk Region, Nunavut, Canada. It is located on Baffin Island's Meta Incognita Peninsula. The Inuit name references the lake's meromictic attribute, a mixture of fresh and salt water caused by a set of reversing falls and 9–10 m (30–33 ft) tides in Pleasant Inlet. The fresh water of Soper River drains into the lake which then drains into the salt water of Pleasant Inlet before reaching the Arctic Ocean.
