Ice Seal Research Results 2019 Tagging

Results from the Summer of 2019:

In June 2019, the NSB DWM commenced seal capture work. We deploy monofilament drift nets along the ice edge during breakup to capture ringed seals, and near sandy spits to capture spotted seals that are hauled out. Length, girth and weight measurements are taken, as well as blood samples for health assessment. Satellite tags are attached to record movements and habitat use and CTD tags include information on water chemistry. The CTD tags are made by the Sea Mammal Research Unit in St. Andrews, Scotland, and the flipper-SPOT tags are made by Wildlife Computers in Redmond, WA. We will continue to send maps throughout the season until the satellite tags stop transmitting. Please feel free to contact Andy Von Duyke at 852-0350 if you have any questions or comments. These seals were tagged as part of a collaborative effort between Alaska Department of Fish and Game, Arctic Marine Mammal Program and North Slope Borough, Department of Wildlife Management staff.

The tagging team consists of staff from the North Slope Borough Department of Wildlife Management (NSB-DWM), Alaska Native hunters from Utqiaġvik, and staff from the Marine Mammal Program at the Alaska Department of Fish and Game (ADFG-MMP): Andy Von Duyke, Joe Skin, Isaac Leavitt, Bobby Sarren, Billy Adams, Vernon Long, Craig George are all from NSB. Anna Bryan, Justin Crawford, and Ryan Adam are with the ADFG-AMMP program.

Funding for this work is provided by the NSB Shell Baseline Studies Program. This seal research is conducted under NMFS permit #20466 and ADF&G Animal Care and Use Committee Protocol #0027-2017-27.

From ADFG Tagging Program:

During the history of this project, seals were tagged in the following locations: Kotzebue Sound, in collaboration with the Native Village of Kotzebue, in 2014; near Koyuk in 2014, 2015, 2016, 2017, and 2018; near Hooper Bay in 2015; near St. Michael in 2015 and 2016; near Scammon Bay in 2016, 2017, and 2018; near Nome in 2016 and 2017; near Utqiaġvik (formerly Barrow) in 2016, 2017, 2018; near Buckland in 2017; and near Nuiqsut in 2017 and 2018. ADFG collaborated with the North Slope Borough Department of Wildlife Management to tag seals near Utqiaġvik and Nuiqsut. ADFG tagged seals in the south north western and south western locations. Funding for seal tagging has been provided by BOEM (SPLASH and SPOT tags, Wildlife Computers, Redmond, WA) and the Office of Naval Research (CTD tags, Sea Mammal Research Unit, University of St. Andrews, UK). The National Oceanic and Atmospheric Administration, Marine Mammal Laboratory provided 14 flipper (SPOT) tags that were deployed on spotted seals. Current seal research is conducted under NMFS permit #20466 issued to ADF&G and under an approved ADF&G Animal Care and Use Committee Protocol #0027-2019-41.

Current maps, archived maps, and additional project information, including the types of tags deployed, and links to updates for our other projects, Ice Seal Biological Monitoring and Harvest Monitoring, can be viewed on the ADFG webpage.

August 10, 2020

See the attached map. From 27 July to 10 August 2020, we received locations for 1 bearded, 4 ringed and 3 spotted seals, all were in the Chukchi and Beaufort seas. The adult bearded seal (BS19-01-M, red square) remained near heavy sea ice, north of the continental shelf, in the western Beaufort Sea. Two ringed seals, RS19-02-M (yellow arrow) and RS19-03-M (orange arrow), were in the western Beaufort Sea, near the shelf break. The remaining two ringed seals, RS19-04-M (blue arrow) and RS19-05-M (purple arrow), were in the northern Chukchi Sea. One spotted seal, SS19-01-M (red circle), was in the western Beaufort Sea and Dease Inlet. The remaining two spotted seals, SS19-04-M (pink circle) and SS19-05-M (purple circle), were near Icy Cape in the Chukchi Sea. These seals were tagged during the summer and fall of 2019. As expected, the primary tags we epoxied to their backs have since fallen off during the annual molt this spring. The locations we are currently receiving are from the SPOT tags we attached to their flippers. Because SPOT tags are attached to their flippers we only receive locations when the seal has hauled out of the water, either on sea ice or land.

July 27, 2020

See the attached map. From 13 to 27 July 2020, we received locations for 1 bearded, 2 ringed and 3 spotted seals, all in the northeast Chukchi and western Beaufort seas. These seals were tagged during the summer and fall of 2019. As expected, the primary tags we epoxied to their backs have since fallen off during the annual molt this spring. The locations we are currently receiving are from the SPOT tags we attached to their flippers. Because SPOT tags are attached to their flippers we only receive locations when the seal has hauled out of the water, either on sea ice or land. The adult bearded seal (BS19-01-M, red square) remained in heavy sea ice and moved off the continental shelf in the Beaufort Sea. The ringed seals, RS19-02-M (yellow arrow) and RS19-03-M (orange arrow), were in the western Beaufort Sea. One spotted seal, SS19-04-M (pink circle), was near Icy Cape in the Chukchi Sea while the two others, SS19-05-M (purple circle) and SS19-06-M (green circle), were in the western Beaufort Sea, generally in and near Dease Inlet.

June 24, 2019

See the attached map. We are pleased to announce that five adult male ringed seals were tagged near Utqiaġvik, Alaska, from 22 to 24 June. We deployed a CTD tag on RS19-01-M, RS19-02-M, and RS19-04-M, and a SPLASH tag on RS19-03-M and RS19-05-M. We also deployed flipper (SPOT) tags on all five seals. One of the five flipper tags was provided by the National Oceanic and Atmospheric Administration, Marine Mammal Laboratory. All five ringed seals made localized movements near Utqiaġvik. Because the tags deployed on these five ringed seals had only been transmitting for up to 3 days, the seals were still relatively close to their tagging location during this update period. Therefore, a second map shows the detail of their localized movements (“zoomed in”). From 10 to 24 June, we also received locations for seals tagged in 2017 and 2018: 2 bearded, 5 ringed, and 2 spotted seals. Bearded seal BS17-02-F, tagged near Koyuk in September 2017, was still in the southern Chukchi Sea, north of the Chukotka Peninsula. Bearded seal BS18-01-F (green square) was still in the northcentral Chukchi Sea, north of Wrangel Island, Russia. One spotted seal was in the Chukchi Sea; SS18-03-F (aqua circle) was near and hauled out on Icy Cape along the Alaskan coast. Spotted seal SS18-02-M (brown circle) made localized movements and hauled out near Scammon Bay. Maps can also be seen on the ADFG webpage.
