The soundscape is an important habitat component for marine animals. In the Arctic, marine conditions are changing rapidly due to sea ice loss and increased anthropogenic activities such as shipping, which will influence the soundscape. Here, we assess the contributors to the summer soundscape in the shallow waters of the Mackenzie River estuary within the Tarium Niryutait Marine Protected Area in the western Canadian Arctic, a core summering habitat for beluga whales (Delphinapterus leucas Pallas, 1776). We collected passive acoustic data during the summer over four years, and assessed the influence of physical variables, beluga whale vocalizations, and boat noise on sound pressure levels in three frequency bands (low: 0.2–1 kHz; medium: 1–10 kHz; high: 10–48 kHz) to quantify the soundscape. Wind speed, wave height, beluga vocalizations, and boat noise were all large contributors to the soundscape in various frequency bands. The soundscape varied to a lesser degree between sites, time of day, and with tide height, but remained relatively constant between years. This study is the first detailed description of a shallow summer soundscape in the western Canadian Arctic, an important habitat for beluga whales, and can be used as a baseline to monitor future changes during this season.

The harvest and consumption of wildlife are integral to the livelihood, culture, and nutritional status of the Inuit of northern Canada. When wildlife populations are perceived to be vulnerable, harvest restrictions may be enacted to protect species conservation interests. Such restrictions may also have consequences for the nutrition and food security of Inuit communities. This study aims to estimate the harvest numbers of key wildlife species needed to sustain the traditional diet of Inuit. Using responses to the food frequency questionnaire that were collected from 806 men and 1275 women during the Inuit Health Study of 2007 – 08, we characterized annual country food consumption in five Inuit regions of northern Canada. Data on average edible yield of food species and Inuit population demographics were compiled and used to estimate the total number of harvested animals. Caribou (Rangifer tarandus) was the species consumed with the highest prevalence (> 90%) and in greatest amounts (29.6 – 122.8 kg/person/yr), depending on sex and region. The annual consumption rate for beluga whale (Delphinapterus leucas) was 5.9 – 24.3 kg per person, depending on sex and region, and that for ringed seal (Pusa hispida) was 4.1 – 25.0 kg per person. To sustain this consumption rate, it is estimated that a mean total of 36 526 caribou, 898 beluga whales, and 17 465 ringed seals are required annually. These results provide a baseline for food security and resource management in the Canadian Arctic to balance Indigenous subsistence needs and wildlife conservation.

Beluga whales (Delphinapterus leucas) are an integral part of many Arctic Indigenous cultures and contribute to food security for communities from Greenland, across northern Canada and Alaska to Chukotka, Russia. Although the harvesting and stewardship practices of Indigenous peoples vary among regions and have shifted and adapted over time, central principles of respect for beluga and sharing of the harvest have remained steadfast. In addition to intra-community cooperation to harvest, process and use beluga whales, rapid environmental change in the Arctic has underscored the need for inter-regional communication as well as collaboration with scientists and managers to sustain beluga populations and their cultural and nutritional roles in Arctic communities. Our paper, written by the overlapping categories of researchers, hunters, and managers, first provides an overview of beluga hunting and collaborative research in seven regions of the Arctic (Greenland; Nunatsiavut, Nunavik, Nunavut, and the Inuvialuit Settlement Region, Canada; Alaska; and Chukotka). Then we present a more detailed case study of collaboration, examining a recent research and management project that utilizes co-production of knowledge to address the conservation of a depleted population of beluga in Nunavik, Canada. We conclude that sustaining traditional values, establishing collaborative management efforts, the equitable inclusion of Indigenous Knowledge, and respectful and meaningful collaborations among hunters, researchers and managers are essential to sustaining healthy beluga populations and the peoples who live with and depend upon them in a time of rapid social and environmental change.
