  • Archaeology Resources
    Archaeology Resources Page Intentionally Left Blank Archaeological Resources Background Archaeological Resources are defined as “any prehistoric or historic district, site, building, structure, or object [including shipwrecks]…Such term includes artifacts, records, and remains which are related to such a district, site, building, structure, or object” (National Historic Preservation Act, Sec. 301 (5) as amended, 16 USC 470w(5)). Archaeological resources are either historic or prehistoric and generally include properties that are 50 years old or older and are any of the following: • Associated with events that have made a significant contribution to the broad patterns of our history • Associated with the lives of persons significant in the past • Embody the distinctive characteristics of a type, period, or method of construction • Represent the work of a master • Possess high artistic values • Present a significant and distinguishable entity whose components may lack individual distinction • Have yielded, or may be likely to yield, information important in history These resources represent the material culture of past generations of a region’s prehistoric and historic inhabitants, and are basic to our understanding of the knowledge, beliefs, art, customs, property systems, and other aspects of the nonmaterial culture. Further, they are subject to National Historic Preservation Act (NHPA) review if they are historic properties, meaning those that are on, or eligible for placement on, the National Register of Historic Places (NRHP). These sites are referred to as historic properties. Section 106 requires agencies to make a reasonable and good faith efforts to identify historic properties. Archaeological resources may be found in the Proposed Project Area both offshore and onshore.

  • Mussel Watchtand Chemical Contamination of the Coasts by Polycyclic Aromatic Hydrocarbons*
    IAEA-SM-354/117 "MUSSEL WATCHTAND CHEMICAL CONTAMINATION OF THE COASTS BY POLYCYCLIC AROMATIC HYDROCARBONS* FARRINGTON, J. W. XA9951933 Woods Hole Oceanographic Institution 360 Woods Hole Road - MS#31 Woods Hole, Massachusetts 02543-1541 U. S. A. Abstract Polycyclic aromatic hydrocarbons (PAH) enter the coastal marine environment from three general categories of sources; pyrogenic, petrogenic (or petroleum), and natural diagenesis. PAH from different sources appear to have differential biological availability related to how the PAH are sorbed, trapped, or chemically bound to particulate matter, including soot. Experience to date with bivalve sentinel organism, or "Mussel Watch", monitoring programs indicates that these programs can provide a reasonable general assessment of the status and trends of biologically available PAH in coastal ecosystems. As fossil fuel use increases in developing countries, it is important that programs such as the International Mussel Watch Program provide assessments of the status and trends of PAH contamination of coastal ecosystems of these countries. 1. INTRODUCTION Modern societies have deliberately and inadvertently discharged or released chemicals of environmental concern to the coastal ocean for decades. The serious nature of several of the ensuing problems identified in the 1960s and early 1970s demonstrated the need for an organized and systematic approach to assessing the status and trends of contamination of coastal and estuarine ecosystems by selected chemicals of major concern. Surveys in the 1960s and early 1970s involving sampling and analysis of various components of coastal and estuarine ecosystems led to the conclusion that much could be learned about spatial and temporal trends by sampling and analyzing carefully chosen populations of bivalves.

  • Canadian Beaufort Sea 2000: the Environmental and Social Setting G
    ARCTIC VOL. 55, SUPP. 1 (2002) P. 4–17 Canadian Beaufort Sea 2000: The Environmental and Social Setting G. BURTON AYLES1 and NORMAN B. SNOW2 (Received 1 March 2001; accepted in revised form 2 January 2002) ABSTRACT. The Beaufort Sea Conference 2000 brought together a diverse group of scientists and residents of the Canadian Beaufort Sea region to review the current state of the region’s renewable resources and to discuss the future management of those resources. In this paper, we briefly describe the physical environment, the social context, and the resource management processes of the Canadian Beaufort Sea region. The Canadian Beaufort Sea land area extends from the Alaska-Canada border east to Amundsen Gulf and includes the northwest of Victoria Island and Banks Island. The area is defined by its geology, landforms, sources of freshwater, ice and snow cover, and climate. The social context of the Canadian Beaufort Sea region has been set by prehistoric Inuit and Gwich’in, European influence, more recent land-claim agreements, and current management regimes for the renewable resources of the Beaufort Sea. Key words: Beaufort Sea, Inuvialuit, geography, environment, ethnography, communities RÉSUMÉ. La Conférence de l’an 2000 sur la mer de Beaufort a attiré un groupe hétérogène de scientifiques et de résidents de la région de la mer de Beaufort en vue d’examiner le statut actuel des ressources renouvelables de cette zone et de discuter de leur gestion future. Dans cet article, on décrit brièvement l’environnement physique, le contexte social et les processus de gestion des ressources de la zone canadienne de la mer de Beaufort.
