  • Aleutian Islands Expedition
    ALEUTIAN ISLANDS EXPEDITION Board your expedition ship in the stunning, remote fishing port of Seward, Alaska, and begin exploring the rugged Alaskan Peninsula coast, where deeply incised fjords give access to glaciers tumbling from icefields high above. Brown bears, whales, dolphins and seals are but some that call this coast home, and wildlife only increases as you traverse the Aleutians, a 1900-km chain of 14 large volcanic islands and 55 smaller ones that forms the Pacific Rim of Fire’s northern arc. This natural boundary separates the Pacific Ocean from the Bering Sea—a designated Mission Blue Hope Spot—creating a dynamic environment that supports amazing biodiversity, including caribou, sea otters, Steller sea lions, orca and gray whales. ITINERARY Delight in black-legged kittiwakes, tufted puffins, crested auklets, peregrine falcon, tundra swans and so much more. Day 1 Anchorage Landings reveal historical relics ranging from Aleut villages and Arrive in Anchorage and transfer to our group hotel. Upon check-in at Hilton Russian fur trade depots to remnants of World War II battles Anchorage Hotel, reception staff will provide you with Aurora Expeditions cabin and Cold War bases.

  • Kelp-Fed Beef, Swimming Caribou, Feral Reindeer, and Their Hunters: Island Mammals in a Marine Economy
    sustainability Article Kelp-Fed Beef, Swimming Caribou, Feral Reindeer, and Their Hunters: Island Mammals in a Marine Economy Katherine Reedy Department of Anthropology, Idaho State University, 921 S. 8th Ave, Stop 8005, ID 83209-8005, USA; [email protected]; Tel.: +1-208-282-2629; Fax: +1-208-282-4944 Academic Editor: Werner T. Flueck Received: 8 December 2015; Accepted: 19 January 2016; Published: 26 January 2016 Abstract: Aleutian Islands and Alaska Peninsula residents have selectively introduced land mammals to their primarily marine based economy over the past two centuries. This paper describes these many introductions, contexts, and the longer term roles of these cattle, sheep, reindeer, and other land mammals in discrete island settings and the regional food economy based upon interviews in ten communities and comprehensive household surveys in eight of these. Caribou are indigenous and traditionally hunted in other parts of the state but are legally “invasive” in island contexts now managed by the federal government. Access to land and natural resources by Alaska Natives and rural peoples is regulated by state and federal agencies, but Aleutian residents have shaped their environment and engineered food sources to support their communities. This paper demonstrates that hardline approaches to removing invasive land mammal species will have human consequences and an integrated management policy emphasizing food security and conservation that includes reducing the density of these introduced species is most appropriate. Keywords: aleutians; introduced species; invasive species; subsistence; conservation; food security 1. Introduction In March 2010, former graduate student Crystal Callahan and I were staying in a Port Heiden, Alaska, bed and breakfast working on a subsistence project when the telephone rang.

  • Postglacial Climate and Vegetation of the Western Alaska Peninsula
    POSTGLACIAL CLIMATE AND VEGETATION OF THE WESTERN ALASKA PENINSULA James W. Jordan, Department of Environmental Studies, Antioch New England Graduate School, Keene, NH 03431 Andrea Krumhardt, Geophysical Institute, University of Alaska, Fairbanks, AK 99775 Abstract: Pollen analysis of a sediment core at Cold Bay, Alaska, indicates a sequence of four vegetation zones representative of trends in postglacial climate. The sequence suggests cool, relatively dry conditions from 9000 – 6200 yr B.P. (14C years); warmer, moister conditions from 6200 – 3200 yr B.P.; cool, moist conditions from 3200 – 2100 yr B.P.; and cool, wet conditions from 2100 – 0 yr B.P. Vegetation throughout the record consisted of treeless tundra dominated by shrubs, herbs, and grasses. Regional pollen records are influenced both by climatic factors and volcanism. The lack of visible volcanic ash deposits in the core described here, and its evidence of a regionally documented shift toward sedge-dominated vegetation about 3000 yr B.P., suggest that the site provides a good approximation of regional climate change during the Holocene. The transition to cooler moister conditions after 3200 yr B.P. is also recorded by coastal dune stabilization on the western Alaska Peninsula, and is broadly correlative with Neoglacial indicators in southern and western Alaska. Changes in solar radiation and shifts in the position and intensity of the Aleutian low-pressure and North Pacific high-pressure centers are the dominant mechanisms of postglacial climate change. Key words: Disturbance, Effective Moisture, Neoglacial Climate INTRODUCTION Investigations of paleoclimatic change are important compared with previous records from the nearest sites in for understanding the mechanisms and consequences of the region – Umnak Island in the eastern Aleutian chain global environmental change.

    The Ninth North American Caribou Workshop, S1 Kuujjuaq, Québec, Canada, 23–27 April, 2001. Rangifer and man: An ancient relationship Bryan Gordon Canadian Museum of Civilization, 100 Laurier st., Gatineau, Québec, Canada J8X 4H2 ([email protected]); home address: 38 Revol Road, Ottawa, Ontario, K2G 0B9. Abstract: A long-term relationship between Rangifer and humans is documented in three case studies: the Canadian Barrenlands (8000 years ago to Historic period), Ice-Age France (11 000-19 000 years ago) and Mesolithic Russia (7000- 10 000 years ago). Ancient human and herd migration occurred in all areas, based upon Rangifer remains and seasonal variations in tools along reconstructed migration routes, with few if any hunting camps outside the routes. An April peak of ancient human births is inferred from the historic record where we see births occurring nine months after peak nutri- tional states in herds and people. The origin of reindeer domestication and breeding in Eurasia is discussed. Key words: Barrenlands, caribou, herd following, hunters, Magdalenian, Mesolithic, reindeer.
