A Watershed Database for National Parks in Southwestern Alaska and a System for Further Watershed-Based Analysis
A Watershed Database for National Parks in Southwestern Alaska and a System for Further Watershed-based Analysis David M. Mixon 2005 Introduction This document describes a project designed to delineate and quantitatively describe watersheds located within or flowing into or out of national park lands in the National Inventory and Monitoring program’s Southwest Alaskan Network (SWAN) of parks. The parks included in this study are Aniakchak National Monument & Preserve, Katmai National Park & Preserve, Lake Clark National Park & Preserve, and Kenai Fjords National Park. This effort was undertaken to support decision-making processes related to the Inventory and Monitoring program’s goals. A variety of environmental and physical attributes were collected for each watershed using remotely sensed data in the form of a geographic information system (GIS). The GIS data used is from a variety of sources with variable quality. The nature of GIS analysis is such that many times a newer, higher-resolution dataset may become available during the course of any given study. For this reason, a set of scripts and methods are provided, making the incorporation of newer datasets as easy as possible. The goal is to provide an initial analysis of park hydrology as well as a means for updating the database with a minimal amount of effort. It was necessary to choose a watershed size (stream order) that would provide sufficient detail for each park and allow useful comparison of basins within the parks while minimizing the complexity of the study. Review of standards for hydrologic unit delineation being used for the National Hydrography Dataset (NHD) (FGDC, 2002), suggested that the officially designated level 5 watersheds would provide the level of detail desired while minimizing redundancy. -
Alaska Range
Alaska Range Introduction The heavily glacierized Alaska Range consists of a number of adjacent and discrete mountain ranges that extend in an arc more than 750 km long (figs. 1, 381). From east to west, named ranges include the Nutzotin, Mentas- ta, Amphitheater, Clearwater, Tokosha, Kichatna, Teocalli, Tordrillo, Terra Cotta, and Revelation Mountains. This arcuate mountain massif spans the area from the White River, just east of the Canadian Border, to Merrill Pass on the western side of Cook Inlet southwest of Anchorage. Many of the indi- Figure 381.—Index map of vidual ranges support glaciers.

Index glaciers range in size from tiny unnamed cirque glaciers with areas of less map modified from Field than 1 km2 to very large valley glaciers with lengths up to 76 km (Denton (1975a).

Alaska Range glaciers extend in elevation from above 6,000 m, near the summit of Mount McKinley, to slightly more than 100 m above sea level at Capps and Triumvi- rate Glaciers in the southwestern part of the range. -

Southcentral Alaska Stock
Revised: April 2014 NORTHERN SEA OTTER (Enhydra lutris kenyoni): Southcentral Alaska Stock STOCK DEFINITION AND GEOGRAPHIC RANGE Sea otters occur in nearshore coastal waters of the U.S. along the North Pacific Rim from the Aleutian Islands to California. The species is most commonly observed within the 40-meter (approximately 12.2 feet [ft]) depth contour because the animals require frequent access to benthic foraging habitat in subtidal and intertidal zones (Reidman and Estes 1990). Sea otters are not migratory and generally do not disperse over long distances, although movements of tens of kilometers (km) (tens of miles [mi]) are common (Garshelis and Garshelis 1984). Annual home range sizes of adult sea otters are relatively small, with male territories ranging from 4 to 11 square kilometers (km2) (approximately 10.5 to 28.5 square miles[mi2]) and adult female home ranges from a few to 24 km2 (approximately 62 mi2) (Garshelis and Garshelis 1984; Ralls et al. 1988; Jameson 1989). Due to their benthic foraging, sea otter distribution is largely limited by their ability to dive to the sea floor (Bodkin et al. 2004). 1 Figure 1. Approximate distribution and stock boundaries of northern sea otters in Alaska waters (shaded area). The spatial scale at which sea otter populations are managed remains an important, although largely unexplored issue (Bodkin and Ballachey 2010) deserving further study. Bodkin and Ballachey (2010) used models of sea otter mortality to show that range-wide reductions and extirpations during the commercial fur trade of the 18th and 19th centuries occurred not simply because of excessive harvest, but because the harvest was not allocated proportional to the abundance and distribution of sea otters. -

ALDRIDGE, Sandia National Laboratories orting out source and path eff ects for seismic waves Sat volcanoes is critical for the proper interpretation of underlying volcanic processes. Source or path eff ects imply that seismic waves interact strongly with the volcanic subsurface, either through partial resonance in a conduit (Garces et al., 2000; Sturton and Neuberg, 2006) or by random scattering in the heterogeneous volcanic edifi ce (Wegler and Luhr, 2001). As a result, both source and path eff ects can cause seismic waves to repeatedly sample parts of the volcano, leading to enhanced sensitivity to small changes in material properties at those locations. Th e challenge for volcano seismologists is to detect and reliably interpret these subtle changes for the purpose of monitoring eruptions. We examine seismic records of repeating explosions from Pavlof volcano, Alaska, during its 2007 eruption. -

Para determinar el efecto de la actividad eruptiva en el régimen glaciar, se realizaron balances de masa empleando técnicas fotogramétricas, mediante la generación de modelos digitales de elevación (MDE). La compa- ración de MDEs permitió establecer los cambios glaciares en términos de área y volumen tanto temporales como espaciales. Así mismo, los cambios morfológicos del área glaciar fueron determinados con base en la fotointerpretación, de manera que los datos obtenidos por este procedimiento y los obtenidos mediante la comparación de los MDE se relacionaron con la actividad eruptiva a lo largo del periodo de estudio, estableciendo así la relación entre los fenómenos volcánicos y los cambios glaciares.
