Health Assessment of Subsistence Resources
Marine mammals, fish, and terrestrial mammals are important subsistence resources for residents of the North Slope. These animals help fill an important nutritional and cultural... -
Western Yellow-billed Loon Monitoring in the Arctic Network of National Parklands
The enabling legislation of the parks specifies protection for bird habitats and populations for all 5 Arctic Network of Alaska Parklands (ARCN). Under ANILCA [Section 201(8)],... -
Contaminants, and Habitat Characteristics in Yellow-billed Loon, 2002-2012
The Yellow-billed Loon (Gavia adamsii) is one of the rarest breeding birds in North America. Because of the small population size and patchy distribution, any stressor to its... -
Heavy metal and mineral concentrations and their relationship to histopathological findings in the bowhead whale (Balaena mysticetus)
This study evaluated the concentration of six essential and non-essential elements (Zn, Hg, Ag,Se, Cu, and Cd) in liver and kidney of 64 bowhead whales. Rosa, C., Blake, J.E.,... -
Vitamin A and E tissue distribution with comparisons to organochlorine concentrations in the serum, blubber and liver of the bowhead whale
Some persistent organic contaminants can have a negative effect on retinol concentration in serum of pinnipeds and cetaceans. Rosa, C., Blake, J.E., L. Mazzaro, P. Hoekstra,... -
Trace elements in tissues of phocid seals harvested in the Alaskan and Canadian Arctic - Influence of age and feeding ecology
Selected trace elements (Ag, Cu, Cd, Se, An, THg, and MeHg) were measured in subsistence harvested seals. Ringed, bearded and spotted seals were obtained from Alaska along with... -
Organic nutrients and contaminants in subsistence species of Alaska: Concentrations and relationship to food preparation method
To determine nutrient and contaminant concentrations, document concentration changes related to common preparation methods and provide a basic risk-benefit analysis for select... -
Serum thyroid hormone concentrations and thyroid histomorphology as biomarkers in bowhead whales.
Serum thyroid hormone (TH) concentrations have been used alone or with other measurements to assess health status or effects of toxicant exposure in marine mammals. Rosa, C.,... -
Persistent organic pollutants in Alaskan ringed seal (Phoca hispida) and walrus (Odobenus rosmarus) blubber
Since 1987, the Alaska Marine Mammal Tissue Archival Project (AMMTAP) has collected tissues from 18 marine mammal species. Specimens are archived in the National Institute of... -
Trophic relationships in an Arctic food web and implications for trace metal transfer
Arctic mammals that were harvested for subsistence were analyzed for Ag, Cd, and THg. Stable carbon and nitrogen isotopes were evaluated to establish trophic interactions within... -
Mercury concentrations in Southern Beaufort Sea polar bears:Variation based on stable isotopes of carbon and nitrogen
Total Hg was measured in 52 adult polar bears captured during 2005 to assess feeding ecology and other biological factors. Cardona-Marek, T., K. K. Knott, B. E. Meyer, T. M.... -
Organohalogen concentrations in blood and adipose tissue of Southern Beaufort Sea polar bears
151 organohalogen chemicals (OHCs) in whole blood and subcutaneous fat of 57 polar bears sampled along the Alaskan Beaufort Sea coast in spring, 2003 were analyzed for major... -
Persistent organochlorine pollutants in ringed seals and polar bears collected from northern Alaska
Blubber samples from ringed seal (Phoca hispida; n=8) and polar bear subcutaneous fat (Ursus maritimus; n=5) were collected near Barrow, Alaska in 1996 as part of the Alaska... -
Establishing precision shoreline GPS coordinates for infrastructure and sites of interest experiencing accelerated erosion
Legacy well sites, former DEW-Line sites, staging areas, roads, airstrips, landfills, dumps, and/or cultural sites experiencing sea, lake, or river shoreline erosion are being... -
Circumpolar pattern of mercury and cadmium in ringed seals
Mercury (Hg) and cadmium (Cd) concentrations in ringed seal liver and kidney were compared from 11 locations across the Arctic, from Alaska, Canada, Greenland, Svalbard to the... -
Concentrations and interactions of selected essential and non-essential elements in bowhead and beluga whales of Arctic Alaska
Concentrations of 12 essential and non-essential elements were studied (As,Cd, Co, Cu, Pb, Mg, Mn, Hg, Mo, Se, Ag and Zn) in bowhead (41) and beluga whale (50). Woshner, V.M.,... -
Bioaccumulation of Organochlorine Contaminants in Bowhead Whales ( Balaena mysticetus ) from Barrow, Alaska
Bowhead whale blubber and liver samples were collected during seven consecutive subsistence harvests (1997–2000) in Barrow, Alaska, to investigate the bioaccumulation of... -
Heavy Metals Concentrations in Alaskan Fishes
Supported by funding from EPA, NOAA and BOEMRE (formerly MMS), The Alaska Department of Environmental Conservation analyzes salmon (all five species), halibut, pacific cod,... -
Dietary biomagnification of organochlorine contaminants in Alaskan polar bears
The variation in PCB153 and oxychlordane concentration are strong indicators of variation in diet and biomagnification of organochlorines among polar bears related to their sex,... -
Investigation of Heavy Metals in a Large Mortality Event in Caribou
