Spatial And Temporal Distribution Of Essential And Non-Essential Elements Recorded In Western Arctic Bowhead Whales (Balaena Mysticetus), Samantha L. Shore
Spatial And Temporal Distribution Of Essential And Non-Essential Elements Recorded In Western Arctic Bowhead Whales (Balaena Mysticetus), Samantha L. Shore
HCNSO Student Theses and Dissertations
Western Arctic bowhead whales, Balaena mysticetus, migrate annually among the Bering, Chukchi, and Beaufort seas. Foraging along their route, they use keratinous baleen to filter microscopic zooplankton from the water column. A single baleen plate from an adult bowhead whale grows continuously and stores 20+ years of dietary and environmental data. This study utilized induced coupled plasma-mass spectrometry (ICP-MS) to evaluate concentrations of 14 essential and non-essential elements in baleen samples from nine subsistence-harvested whales, yielding continuous data from 1958–1999 (n=148). Stable isotope data previously reported on these samples provided information on location (Beaufort Sea; Bering/Chukchi seas), season (winter; …
Increasing Shipping Traffic Through The Bering Strait: Challenges Of International Policy In A Rapidly Changing Climate And Managing Impacts To Regional Cetacean Populations, Laura Morse
HCNSO Student Capstones
The Arctic region is experiencing growth in marine traffic as seasonal ice conditions shift to longer periods of open water and vessel improvements that have allowed for transit in heavier ice conditions. Regionally, Russia is improving existing transportation infrastructure to support increased traffic along the Northern Sea Route. As a result of these and other factors, shipping traffic is increasing through the Bering Strait and Bering Sea. Regulating traffic in these areas is more complex than most other areas in US waters given the presence of an international strait subject to international regulation through the International Maritime Organization. The US …
