Part 1: Remote tagging. We would like to use remote tags to gather information about the dive behaviour of narwhals. Our goal would be to deploy the tags on the whales before an aerial survey (NIRB File #23YN020) so that we can get locations of the whales at the same time the survey is being flown. Tags usually last a few weeks but have lasted for many months in the past. The tags provide information on location when the whale surfaces, as well as information on the depth and time of their dives. Our team would attempt to deploy tags on the narwhals backs using a crossbow, from either shore, boat, or kayak. Although we have never tried to remotely tag narwhals, we have had success with this method on belugas, killer whales and bowhead whales. We would like to try this method because it is less invasive and less stressful for the animals than capturing them in a net to put a tag on their back. In this way there would be no direct contact between the human and the whale. Part 2: Drone work. We have two goals for the drone work: 1) To collect footage of narwhals swimming at and near the surface of the water, to follow them for as long as possible and get information on their dive behaviour and how long they stay underwater. If successful, this information can be useful in narwhal abundance estimate, by correcting for the time the animals spend underwater versus at the surface. 2) To collect footage of narwhals to look at their body condition by comparing their length to width at different points along the body. We can also determine the number of males, females and calves in groups .We would fly the drone from shore or boat at a height of 20 meters or more to ensure we do not disturb the animals. The drone will fly directly overhead to ensure we get a straight down view of the whales, and will follow the whales until they cannot be seen or the drone battery runs out, usually a maximum of 20 minutes.
