ABSTRACT

Due to climate change the high Arctic is experiencing growth in acoustic
anthropogenic disturbance that may affect aquatic species, such as Arctic cod
(Boreogadus saida), and Inuit residents. To our knowledge, no studies have been
conducted on this topic and species. Furthermore, there is urgent need for
conservation action through much needed collaboration between Inuit and
researchers, and an engagement of different audiences, and thus, a documentary
film was added to the project as means of communication. Resolute Bay is a small
Inuit community located just north of the Northwest Passage, where ships are often
visitors in the summer and the bay is a home to Arctic cod, making this the perfect
location to address this gap of knowledge and communication. In Chapter 2, we
show that Arctic cod was horizontally displaced from its home range and
individuals reduced the extent of their habitat use and changed their swimming
patterns during vessel presence and movement. In Chapter 3, we describe and put
into context the different techniques the film uses to accomplish the set objectives:
highlighting the issues facing the Inuit and the arctic ecosystem, the value of Inuit
traditional ecological knowledge and need for its incorporation into future studies
in the region. Arctic cod spatial distribution and behavioral changes carry
consequences for the whole Arctic ecosystem and need to be well understood by
scientists as well as by a wide range of audiences to allow for sustainable
management and timely conservation action.
