Iñupiaq, Yup'ik, and Cup'ik hunters in 14 Alaska Native communities described a rapidly changing marine environment in qualitative traditional knowledge interviews conducted over the course of a decade with individuals. Based on their observations, sea ice conditions are the most notable change, with later freeze-up, thinner and less reliable ice, and earlier and more rapid by: 6. Samples. Ringed seals, P. hispida, (n = 19), 12 young-of-the-year (YOY) or juvenile females (10 Age = 0 (YOY), 1 Age = 2, 1 Age = 4) and 7 YOY or juvenile males (6 Age = 0, 1 Age = 1), were collected by Inuit hunters and sampled in and at Salluit, Nunavik, Quebec (62°13′N, 75°39′W) ().In addition, tissues from four ringed seals were collected from Inukjuak, Nunavik, Quebec.
An intensive study combining aerial surveys and satellite tracking revealed strong seasonal changes in the abundance, distribution, and marine habitat use of harbor seals in Cook Inlet, a major estuarine system in the Gulf of Alaska. On J , the U.S. District Court for the District of Alaska overturned the National Marine Fisheries Service (NMFS) listing of the Beringia population of bearded seals as threatened under the Endangered Species Act. Arctic ringed seals can be .
Barrow Canyon is a submarine canyon that straddles the boundary between the Beaufort and Chukchi seas. Compared to other nearby areas and the Canada Basin, the highly productive Barrow Canyon supports a diversity of marine animals and invertebrates. Abstract. This chapter reviews the information on contaminants in Arctic ringed seals available till We have limited the contaminants to persistent organic pollutants (POPs), mercury (Hg), and cadmium (Cd) because the majority of studies have focused on these and they represent the contaminants of greatest concern both for the seals and for the exposure of humans consuming Cited by: 4.

Gilbert Department of Wildlife. The Arctic ringed seal (Pusa hispida hispida) is a subspecies of ringed seals (Pusa hispida).Arctic ringed seals inhabit the Arctic Ocean, and are the most abundant and wide-ranging seal in the Northern Hemisphere.
The ringed seal species is the smallest true seal, and gets its name from a distinctive patterning of light spots on dark grey colored : Mammalia. A survey in the late s resulted in a population estimate for the Okhotsk ringed seal P.h. ochotensis of about- 1, seals in the Okhotsk Sea and northern Japan (Bychkov, ), but present abundance must be considered to be unknown (Kovacs et al.
An Aerial Census of Ringed Northern Coast of Alaska Seals, JOHN J. BURNS and SAMUEL J. HARBO, JR.2 ABSTRACT. Aerial surveys of ringed seals, Phoca (Pusa) hispida Schreber, in areas of land-fast ice extending along the Alaskan coast from Point Lay to Barter Island.

SDA no Wilson, Pamela L. Between the late s and late s, declines of 60% to more than 80% were documented for harbor seals in some trend count areas in the northern Gulf of Alaska (PitcherFrost et al.
A total of 1, seals were counted, and when accounting for ice areas that were not covered by images, a total of 3, (95% Cl: 3,) ringed seals were estimated to be hauled out during.
Prioritizing habitats based on abundance and distribution of molting waterfowl in the Teshekpuk Lake Special Area of the National Petroleum Reserve, Alaska The National Petroleum Reserve in Alaska (NPR-A) encompasses more than million hectares of federally managed land on the Arctic Coastal Plain of northern Alaska, where it supports a.
Alaska's dynamic, often ice-covered seas are home to a remarkable diversity of life—crustaceans, fish, seals, sea lions, porpoises, whales, and more. Few places in the world offer such beauty and bounty. This region of nearly million square miles includes waters in the Gulf of Alaska, Bering Sea, Aleutian Islands, Chukchi Sea, and.
Lesions and other symptoms associated with sickened or dead ringed seals along Alaska's northern coast last year were probably not caused by radiation, the National Oceanic and Atmospheric.

Prepared by Western EcoSystems Technology, Inc. (WEST), Laramie, Wyoming. August 5, Ringed seals have the widest distribution, which includes the Bering, Chukchi, and Beaufort seas near Alaska, but they are also found throughout the Arctic, including Canada, Greenland, Svalbard, and Russia, and in freshwater lakes in Europe.
Ringed seals feed on. Baltic ringed seals: (1) Some protected areas in Sweden, Finland, the Russian Federation, and Estonia include Baltic ringed seal habitat; (2) the Baltic ringed seal is included in the Red Book of the Russian Federation as “Category 2” (decreasing abundance), is classified as “Endangered” in the Red Data Book of Estonia, and is listed as.
Peter Boveng is the leader of the Polar Ecosystems Program for research on harbor seals and ice-associated (ringed, bearded, spotted, and ribbon) seals in Alaska. His primary research interests are in the estimation of fundamental quantities for population assessment, such as abundance, trends, and vital rates, and in satellite telemetry.

continued monitoring of stable isotopes of ringed seals provides an archive of ecological changes within the Arctic food web. Current monitoring of UK harbour seals, using wider‐scale aerial survey techniques, has provided important estimates of site distribution and relative abundance at regional and national scales.
However, these larger‐scale surveys lack associated data Cited by: Ringed seals are facing predicted declines in their sea ice habitat due to climate change and possible threats from industrial development, such as increased shipping and oil and gas exploration.
What effects these changes in their environment might have on ringed seals can only be addressed appropriately when we understand the basic biology of. traditions with a profound respect for arctic ringed seals and other wildlife that share their habitat.

The report summarizes the investigations of the distribution, abundance, migration timing and route, behavior, and habitat relationships of endangered whales in the Alaskan Chukchi and western Beaufort seas (hereafter, study area); was the third year of a three year () study.
Called “kerosene seals” for rutting males in April and May who emit smelly scent from facial glands (ADF&G). “Ice seals” include ringed seals, ribbon seals, spotted seals and bearded seals.
These are also known as “hair seals” or “true seals” (ADF&G ). Older references (John Murdoch ’s) may call them phoca foetida.
