Ecoregional-scale monitoring within conservation areas, in a rapidly changing climate
Erik A. Beever, Andrea Woodward
2011, Biological Conservation (144) 1255-1257
Long-term monitoring of ecological systems can prove invaluable for resource management and conservation. Such monitoring can: (1) detect instances of long-term trend (either improvement or deterioration) in monitored resources, thus providing an early-warning indication of system change to resource managers; (2) inform management decisions and help assess the effects of...
The Cannery Formation: Devonian to Early Permian arc-marginal deposits within the Alexander Terrane, southeastern Alaska
Susan M. Karl, Paul W. Layer, Anita G. Harris, Peter J. Haeussler, Benita L. Murchey
2011, Professional Paper 1776-B
The Cannery Formation consists of green, red, and gray ribbon chert, siliceous siltstone, graywacke-chert turbidites, and volcaniclastic sandstone. Because it contains early Permian fossils at and near its type area in Cannery Cove, on Admiralty Island in southeastern Alaska, the formation was originally defined as a Permian stratigraphic unit. Similar...

Conceptual ecological models to support detection of ecological change on Alaska National Wildlife Refuges
Andrea Woodward, Erik A. Beever
2011, Open-File Report 2011-1085
More than 31 million hectares of land are protected and managed in 16 refuges by the U.S. Fish and Wildlife Service (USFWS) in Alaska. The vastness and isolation of Alaskan refuges give rise to relatively intact and complete ecosystems. The potential for these lands to provide habitat for trust species...

Review of the origin of the Braid Scarp near the Pebble prospect, southwestern Alaska
Peter J. Haeussler, Christopher F. Waythomas
2011, Open-File Report 2011-1028
A linear geomorphic scarp, referred to as the 'Braid Scarp,' lies about 5 kilometers north of Iliamna Lake, Alaska, and has been identified as a possible seismically active fault. We examined the geomorphology of the area and an 8.5-meter-long excavation across the scarp. We conclude that the scarp was formed...

Timothy Collett, Ray Boswell, Myung W. Lee, Brian J. Anderson, Kelly K. Rose, Kristen A. Lewis
2011, Conference Paper, OTC Arctic Technology Conference 2011
The results of short duration formation tests in northern Alaska and Canada have further documented the energy resource potential of gas hydrates and justified the need for long-term gas hydrate production testing. Additional data acquisition and long-term production testing could improve the understanding of the response of naturally-occurring gas hydrate...
