He established a Japanese research team focused on marine pollution and hazardous chemicals using marine mammals as an indica- tor species. Dr. Miyazaki organized the research project “Coastal Marine Environment” that was conducted by United Nations University, Ocean Research Institute of The University of Tokyo, and Iwate Prefecture. He worked as general coor- dinator of the Japanese Society for Promotion of Science’s Multilateral Core Univer sity Program “Coastal Marine Science” with other distinguished scientists from five Asian countries. In collabora- tion with Dr. Y.

  • Ecology of Ringed Seals (Phoca Hispida) in Western Hudson Bay, Canada
    Ecology of ringed seals (Phoca hispida) in western Hudson Bay, Canada by Magaly Vincent-Chambellant A Thesis submitted to the Faculty of Graduate Studies of The University of Manitoba in partial fulfilment of the requirements of the degree of DOCTOR OF PHILOSOPHY Department of Biological Sciences University of Manitoba Winnipeg Copyright © 2010 by Magaly Vincent-Chambellant Abstract Recently, Hudson Bay experienced unidirectional trends in temperature, sea-ice extent, time of break-up, and length of the open-water season. Predicted impacts on population dynamics of ice-associated species include habitat loss and shift in prey availability. The ringed seal (Phoca hispida) depends on a stable ice platform with sufficient snow depth and a productive open-water season for reproduction and survival. Evidence of ringed seal sensitivity to environmental variations has been reported, but mechanisms involved were poorly understood. In western Hudson Bay, density, life-history traits, and diet of ringed seals were monitored over two decades, providing an opportunity to understand the effects of climatic variations on the population dynamics of this long-lived carnivore. Ringed seal density was estimated through strip-transect analyses after aerial surveys were flown in western Hudson Bay in late spring during the annual moult in the 1990s and 2000s. During these periods, ringed seals were also sampled from Inuit subsistence fall harvests In Arviat, NU, and ages, reproductive status, percentage of pups in the harvest, body condition, and diet were assessed. Strong inter-annual variations in these parameters were observed, and a decadal cycle was suggested and related to variations in the sea-ice regime.

  • Ringed Seal Winter Ecology and Effects of Noise Disturbance

Kelly, Principal Investigator with Lori T. Quakenbush and John R. Rose Institute of Marine Science University of Alaska Fairbanks, Alaska 99775-1080 December 1986 •• • ABSTRACT Ringed seals abandon subnivean breathing holes and lairs at higher than normal rates in response to seismic (Vibroseis) surveying and, probably, other human-made noises. The significance of such abandonment was assessed in a telemetric study of lair occupation by ringed seals. Temporal and spatial haul-out patterns of 13 radio-tagged seals were recorded from early March through early June in the Beaufort Sea and in Kotzebue Sound. Both male and female ringed seals haul out in more than one, and as many as four, alternative subnivean lairs. At least one lair was used by more than one seal. Distances between lairs used by individual seals were as great as 4 km with numerous breathing holes between those sites. The percentage of once-hourly monitoring periods in which seals were hauled out in lairs increased from 11.5% in March to 17.8% in April, 20.4% in May, and 27.2% in June. Individual haul-out bouts averaged 5.4 hours; nonhaul-out bouts averaged 18.9 hours. Post-parturient females hauled out most regularly and did so in significantly longer bouts during the nursing period than before or after that period. Diel haul-out patterns tended to be weak or absent in March and April but became pronounced with midday peaks in late May and early June.

  • The Subsistence Harvest of Seals and Sea Lions by Alaska Natives in the Norton Sound-Bering Strait Region, Alaska, 1996-97
    The Subsistence Harvest of Seals and Sea Lions by Alaska Natives in the Norton Sound-Bering Strait Region, Alaska, 1996-97 Technical Paper No. 242 by Susan Georgette, Michael Coff ing, Cheryl Scott, and Charles Utermohle Final Report NOAA Grant No. NA66FX0476 Prepared for the National Marine Fisheries Service Alaska Department of Fish and Game Division of Subsistence Juneau, Alaska April 1998 ABSTRACT This report describes the subsistence takes of bearded seal (Erignathus barbafus), ringed seal (Phoca hispicfa), spotted seal (Phoca largha), ribbon seal (Phoca fasciafa), and Steller sea lion (Eumefopias jubafus) by Alaska Natives in selected communities in the Norton Sound-Bering Strait region of northwest Alaska during the 1Bmonth period February 1996 through January 1997. The information, including size of take, seasons, geographic distribution, and age and sex of the harvest, derives from systematic interviews with hunters and users of marine mammals in 319 households in six of 16 communities in the Norton Sound-Bering Strait area (Brevig Mission, Gambell, Golovin, Savoonga, Shaktoolik, and Stebbins). The research was conducted cooperatively by Kawerak, Inc., a non-proft, regional Native organization, and the Division of Subsistence, Alaska Department of Fish and Game, under contract with the National Marine Fisheries Service. Local research assistants trained as part of the project assisted in the collection of information. During the study year, the estimated subsistence take of all seals by Alaska Natives in the six communities was 4,223 seals. Of the take, 86.7 percent (3,660 seals) were harvested and 13.3 percent (563 seals) were struck and lost. In terms of numbers, the regional seal take was fairly evenly divided among bearded seal (36.2 percent of total take), ringed seal (33.1 percent), and spotted seal (29.0 percent).
