Summary of marine mammal aerial surveys in Norwegian Bay and Ellesmere Island, Nunavut in 2022 / by Katie R.N. Florko, Tera Edkins, Steven H. Ferguson, David J. Yurkowski, and Christine Michel. : Fs97-6/3534E-PDF
"We surveyed Norwegian Bay and the nearby fiords on Ellesmere Island, Nunavut, which is a region that has limited current data, for marine mammals in August 2022. We recorded the species, number of individuals, and distribution of marine mammals using visual observations, photography, and infrared imagery. We recorded 72 marine mammal observations including polar bears, ringed seals, narwhal (Monodon monoceros), and bearded seals (Erignathus barbatus). Most of our observations were in western and central Norwegian Bay, which is the only area in our study area with concentrated sea ice, perhaps highlighting the importance of summer sea ice for marine mammals. There were few marine mammal sightings in the nearby (open-water) fiords. Further reductions in sea ice may change the distribution and abundance of marine mammals throughout the Canadian High Arctic and thus, there is a need for continued monitoring of these regions to understand how marine mammals respond to reduced sea ice"--Abstract.
