Changes in Sea Ice and Range Expansion of Sperm Whales in the Pond Inlet Region of Baffin Bay, Canada
Sperm whales are a cosmopolitan species only found in ice-free regions. Understanding the distribution of sperm whales in regions undergoing rapid loss of sea ice and ocean warming is important. In 2014 and 2018, sperm whales were sighted in the Pond Inlet, Baffin Bay: the first recorded uses of thi...

Sperm whales are a cosmopolitan species only found in ice-free regions. Understanding the distribution of sperm whales in regions undergoing rapid loss of sea ice and ocean warming is important. In 2014 and 2018, sperm whales were sighted in the Pond Inlet, Baffin Bay: the first recorded uses of this region. We investigated sperm whale distribution near the Pond Inlet using visual sighting and passive acoustic data from two recording sites between 2015 and 2019. We found no records of sperm whale sightings near Pond Inlet outside of the 2014/2018 observations.
