Most Recent Tracking Map
During the last fourteen days we have received locations for 1 ringed seal (solid red line) and 1 bearded seal (dashed blue line). The ringed seal, RS14-01-M, is near the mouth of Kotzebue Sound. Last week, the bearded seal, BS15-07-M, moved away from the coast and into the middle of Norton Sound, near a patch of remnant sea ice. An updated map showing recent movements is attached.

Project Overview

There are four species of seals in Alaska that are referred to as “ice associated seals” or “ice seals” because they use sea ice for some important life history events such as pupping, nursing, molting, and resting. Ringed (Pusa hispida), bearded (Erignathus barbatus), spotted (Phoca largha), and ribbon (Histriophoca fasciata) seals are all used for subsistence by coastal Alaska Natives for food, oil, materials, clothing, and handicrafts. Ice seals are found in the Bering, Chukchi, and Beaufort seas but little is known about the timing and magnitude of their movements by species and even less is known about movements by sex and age classes and whether individuals return to the same places seasonally and what important habitats are. Reductions in sea ice have increased interest in shipping and oil and gas activities, which increases the need to understand ice seal movements and habitat use in order to plan shipping lanes, oil and gas lease sales, and to develop effective mitigation measures for their protection. A combination of satellite tag technology and the skills of Native subsistence seal hunters to capture seals and deploy transmitters will greatly increase our knowledge of seal movements and behavior in a relatively short period of time. The focus of this study is to work with interested seal hunters at different villages along the west and north coasts of Alaska to capture and deploy satellite transmitters on ringed, bearded, spotted, and possibly ribbon seals. Tracking seals tagged at multiple locations, potentially as far south as Bristol Bay and as far north as Kaktovik, will allow us to better understand the range and timing of movements, use of sea ice including haulout behavior, important habitats, degree of seasonal site fidelity, and behavior near ships, including seismic and other petroleum related activities. Seal research is conducted under NMFS permit #15324 and ADF&G Animal Care and Use Permit #2014-03.

Tagging activities in 2015

May 2015: We tagged 1 young male ringed seal on 14 May. This seal was tagged near the community of Hooper Bay by Albert Simon 2nd. Albert 2nd was assisted by Mark Nelson (ADF&G).

August 2015: During August we tagged 8 bearded and 1 ringed seal in the Norton Sound region. We tagged 4 young bearded seals (2 male and 2 female) on 18–20 August about 15 miles up the Koyuk River from the community of Koyuk. These seals were tagged by a local seal hunter and reindeer herder Merlin Henry. We also tagged 4 young bearded seals (2 male and 2 female) and 1 young female ringed seal on 22 and 23 August in St. Michael Canal and Little St. Michael Canal, near the community of St. Michael. These seals were tagged by a local crew of seal hunters Alexander Niksik and Palsson Fitka. The hunter-taggers in both locations were assisted by Mark Nelson (ADF&G).

Tagging activities in 2014

June 2014: We tagged 4 adult ringed seals (2 male and 2 female) and 1 young male bearded seal on 18 and 19 June. The seals were tagged south of Kotzebue by the local crew consisting of John Goodwin, Pearl Goodwin, Boyuk Goodwin, Frank Garfield, Edward Ahyakak, and Denali Whiting with logistics assistance by Alex Whiting. The non-local crew included Kathy Frost and Mark Nelson.

September 2014: We tagged 3 young male bearded seals between 26 and 30 September about 15 miles up the Koyuk River from the community of Koyuk. The seals were tagged by a local seal hunter and reindeer herder Merlin Henry and Mark Nelson.

Previous Ice Seal Movement and Habitat Use Studies

We have worked with seal hunters from the Native Village of Kotzebue to capture and tag ringed seals to learn more about movements and habitat use. We are expanding this project to other villages.
