Using western science and Inuit knowledge to model ship-source noise exposure for cetaceans (marine mammals) in Tallurutiup Imanga (Lancaster Sound), Nunavut, Canada
Tallurutiup Imanga (TI) is a National Marine Conservation Area (NMCA) established in 2019 at the eastern entrance of the Northwest Passage in Lancaster Sound, Nunavut, Canada, to protect 110,000 square kilometres of core habitat for cetaceans. This study examines the potential impacts of underwater noise from increased ship traffic in TI NMCA on three cetaceans: narwhal, beluga whale, and bowhead whale. Automatic Identification System data from 2…
Use of the Alaskan Beaufort Sea by Bowhead Whales (Balaena mysticetus) Tagged with Satellite Transmitters, 2006 – 18
We used satellite telemetry to examine bowhead whale movement behavior, residence times, and dive behavior in the Alaskan Beaufort Sea, 2006 – 18. We explored the timing and duration of use of three subregions (western, central, eastern) within the Alaskan Beaufort Sea and applied a two-state switching state-space model to infer bowhead whale behavior state as either transiting or lingering. Transiting whales made direct movements whereas lingeri…
Life around the North Water ecosystem
The formation of the North Water in Smith Sound about 4500 years ago, as evidenced by the establishment of bird colonies and human presence, also initiated a long-term anthropogenic agent as part of this High Arctic ecosystem. Different epochs have influenced the human occupation in the area: immigration pulses from Canada and Alaska, trade with meteorite iron throughout the Arctic, introduction of new technologies by whalers and explorers, explo…
Is sustainable resource utilisation a relevant concept in Avanersuaq? The walrus case
This article addresses the role of Atlantic walrus (Odobenus rosmarus rosmarus) in present-day Avanersuaq from anthropological and biological perspectives, and asks whether or not sustainable resource utilisation is a useful concept in northwest Greenland. We describe the relations that unfold around walrus and walrus hunting, in the communities living adjacent to the North Water polynya on the eastern side of Smith Sound. We examine the interpla…
Movements and Inferred Foraging by Bowhead Whales in the Canadian Beaufort Sea during August and September, 2006–12
Each spring, most bowhead whales of the Bering-Chukchi-Beaufort (BCB) population migrate to the southeast Beaufort Sea and summer in Canadian waters. In August and September, they form aggregations, which are known to occur mainly in the shallow, shelf waters when oceanographic conditions promote concentration of their zooplankton prey. The movements of individual bowheads while they occupy these late summer habitats are less well known; our know…
Walrus Movements in Smith Sound
Fifty of 58 walruses (Odobenus rosmarus rosmarus) instrumented with satellite-linked transmitters in four areas in eastern Smith Sound, Northwest Greenland, during May and June of 2010 – 13 and 2015 provided data for this study. These animals departed from the feeding banks along the Greenland coast in June – July (average 14th June), simultaneously with the disappearance of sea ice from these areas. Most of them moved to Canadian waters in weste…

Identification of Potential Foraging Areas for Bowhead Whales in Baffin Bay and Adjacent Waters
The bowhead whale (Balaena mysticetus) is the Arctic’s largest and most dependent predator on zooplankton; however, knowledge about its important foraging areas in Baffin Bay and adjacent waters is limited. Data on movement, horizontal velocity (ms-1), dive depth (m), and dive rate (dives h-1) were obtained from 39 bowhead whales (31 females, 6 males, and 2 of undetermined sex) instrumented with satellite-linked time-depth recorders (SLTDRs) in s…
Lost Highway Not Forgotten
The Spitsbergen bowhead whale stock is critically endangered. It is believed to number in the tens. Here we report results from the first satellite transmitter ever deployed on an individual from this stock. A female whale was tagged on 3 April 2010 (at 79 ̊54' N, 01 ̊03' E), but no locations were transmitted by the tag until 30 April 2010, after which data were received continuously for 86 days. Additionally, three small clusters of locations we…
Winter Movements of Bowhead Whales ( Balaena mysticetus ) in the Bering Sea
Working with subsistence whale hunters, we tagged bowhead whales (Balaena mysticetus) with satellite-linked transmitters and documented their movements in the Bering Sea during two winters. We followed 11 whales through the winter of 2008 – 09 and 10 whales in 2009 – 10. The average date that bowhead whales entered the Bering Sea was 14 December in 2008 and 26 November in 2009. All but one tagged whale entered the Bering Sea west of Big Diomede I…
Fall and Winter Movements of Bowhead Whales ( Balaena mysticetus ) in the Chukchi Sea and Within a Potential Petroleum Development Area
Working with subsistence whale hunters, we tagged 19 mostly immature bowhead whales (Balaena mysticetus) with satellite-linked transmitters between May 2006 and September 2008 and documented their movements in the Chukchi Sea from late August through December. From Point Barrow, Alaska, most whales moved west through the Chukchi Sea between 71 ̊ and 74 ̊ N latitude; nine whales crossed in six to nine days. Three whales returned to Point Barrow fo…
Baffin Bay Narwhal Population Distribution and Numbers
Aerial surveys of narwhals (Monodon monoceros) were conducted in the Canadian High Arctic during the month of August from 2002 to 2004. The surveys covered the waters of Barrow Strait, Prince Regent Inlet, the Gulf of Boothia, Admiralty Inlet, Eclipse Sound, and the eastern coast of Baffin Island, using systematic sampling methods. Fiords were flown along a single transect down the middle. Near-surface population estimates increased by 1.9 %– 8.7…
Resighting of a Narwhal ( Monodon monoceros ) Instrumented with a Satellite Transmitter
On 9 August 2001, a male narwhal (Monodon monoceros) was instrumented with a satellite transmitter attached to the dorsal side of the tusk in Creswell Bay on Somerset Island in the Canadian High Arctic. The whale was identified five years later, on 22 June 2006, in a photo of a group of narwhals taken from the ice edge in Lancaster Sound. Examination of the position of the transmitter on the tusk showed that the tusk had grown approximately 17 cm…
Declining Extent of Open-water Refugia for Top Predators in Baffin Bay and Adjacent Waters
Global climate change is expected to severely impact Arctic ecosystems, yet predictions of impacts are complicated by region-specific patterns and nonuniform trends. Twentyfour open-water overwintering areas (or “microhabitats”) were identified to be of particular importance for eight seabird and marine mammal species in the eastern Canadian High Arctic and Baffin Bay. Localized trends in the available fraction of open-water were examined in Marc…

From Greenland to Canada in Ten Days
Five bowhead whales (Balaena mysticetus) were instrumented with satellite transmitters in northwestern Disko Bay, West Greenland, in May 2001. Best results were obtained when tags were deployed with a pole rather than a pneumatic gun. At least three of the tagged whales remained in the northwestern part of the bay for one to two weeks after tagging. A male and a female whale moved from Disko Bay to northern Canada. They left Disko Bay 11 days apa…
Surfacing Times and Dive Rates for Narwhals ( Monodon monoceros ) and Belugas ( Delphinapterus leucas )
Time spent at and near the sea surface was measured for 25 narwhals, Monodon monoceros, and 39 belugas or white whales, Delphinapterus leucas, in West Greenland and Canada from 1993 through 1999, using satellite-linked data recorders. Narwhals spent less time at the surface than belugas did, and the surfacing time of belugas also varied between localities. No clear differences in surfacing time were associated with the time of day, but belugas te…
Summer and Fall Movements of Narwhals ( Monodon monoceros ) from Northeastern Baffin Island towards Northern Davis Strait
Ten narwhals (Monodon monoceros) were instrumented with satellite-linked radio transmitters in Tremblay Sound in August 1997 (N = 5) and August 1998 (N = 5). All whales stayed in the waters around Bylot Island until the end of September. On the basis of these animals and others tagged previously (total N = 24), it is believed that the Bylot Island summering population has limited or no contact with other summering populations in Canada or Greenla…
Summer and Autumn Movements and Habitat Use by Belugas in the Canadian High Arctic and Adjacent Areas
Twenty-one adult belugas (8M, 13F) were live-captured and instrumented with satellite-linked transmitters in the summer and fall of 1996. Twelve were captured in estuaries along the coast of Somerset Island in July and nine were captured in September in Croker Bay, SE Devon Island. This paper reports on the summer and autumn movements and dive depths of these animals from late July 1996 until the last tags ceased transmitting in November 1996. Of…
Fall Movements of Belugas ( Delphinapterus leucas ) with Satellite-linked Transmitters in Lancaster Sound, Jones Sound, and Northern Baffin Bay
Six adult belugas, Delphinapterus leucas, (2 males, 4 females) were instrumented with satellite-linked transmitters in Croker Bay, southeastern Devon Island in the Canadian High Arctic in mid-September 1995. Some days, the animals remained close to shore along the southeastern and eastern shoreline of Devon Island, presumably foraging for arctic cod (Boreogadus saida) and other prey. They spent the rest of the time in the deep waters of Lady Ann …
Dive Patterns of Belugas ( Delphinapterus leucas ) in Waters Near Eastern Devon Island
Data were obtained for six belugas or white whales (Delphinapterus leucas) instrumented with satellite-linked dive recorders in September-November 1995 in waters near eastern Devon Island, Canada. The mean of the daily maximum depths of dives was 483-665 m for the 31-51 days when maximum depth measurements were taken. The deepest dive recorded was 872 m. Both the dive rate (number of dives per hour to depths > 8 m) and the time at surface (time s…
Photographic Reidentification of a Bowhead Whale in Davis Strait
An adult bowhead whale photographed at Isabella Bay, Baffin Island, on 28 September 1986 was reidentified from a photograph taken off West Greenland on 10 April 1990. The "recapture" distance was about 460 km across Davis Strait. The recapture is consistent with historical knowledge of the seasonal distribution of bowhead whales and is supportive of the hypothesis that bowheads circulate within the Baffin Bay - Davis Strait area as part of a disc…
