This report contains all of the available daily sulfur dioxide andcarbon dioxide emission rates from Cook Inlet volcanoes asdetermined by the U.S. Geological Survey (USGS) from March 1990through July 1994. Airborne sulfur dioxide gas sampling of theCook Inlet volcanoes (Redoubt, Spurr, Iliamna, and Augustine)began in 1986 when several measurements were carried out atAugustine volcano during the eruption of 1986. Systematic monitoringfor sulfur dioxide and carbon dioxide began in March 1990 atRedoubt volcano and continues to the present. Intermittentmeasurements at Augustine and Iliamna volcanoes began in 1990 andcontinues to the present. Intermittent measurements began at Spurrvolcano in 1991, and were continued...
This publication contains previously unpublished geochemical analyses or re-analyses of lavas, magmatic inclusions, and a few gabbroic cumulate inclusions from Alaska volcanoes (Akutan, Augustine, Buzzard Creek, Dana, Douglas, Fourpeaked, Frosty, Great Sitkin, Iliamna, Kaguyak, Kiska, Okmok, Prindle Cone, Recheshnoi, Redoubt, Spurr, Ukinrek Maars, Vsevidof, Westdahl, Wrangell) collected by the authors and others over the past 35 years. It provides substantial data sets for three volcanoes (Vsevidof, Westdahl, and Douglas) for which little or no published data exist. All analyses were made by the GeoAnalytical laboratory at Washington State University in Pullman, WA. The ICP/MS data have been reduced using the 2006...

Between 1979 and 1982, the Alaska Division of Geological & Geophysical Surveys (DGGS) and the Geophysical Institute, University of Alaska Fairbanks, undertook an assessment of the states geothermal resources under a program jointly sponsored by the U.S. Department of Energy and the State of Alaska. During this period, reconnaissance investigations of more than 100 thermal spring sites and fumarole fields located in Alaska were conducted by DGGS.

The 2009 eruption of Redoubt Volcano included 19 major tephra-producing explosions. Mass per unit area (MPUA) ash fall sampling of the resulting deposits allowed us to create isomass contours of the ash fall. This dataset contains the vector digital shapefiles of the ash fall contours for the explosive events. In addition, a point digital shapefile is included that describes more than 400 ash fall samples that were collected. For a detailed account of the 2009 eruption of Redoubt Volcano, see Schaefer, J.R., ed., 2012, The 2009 eruption of Redoubt Volcano, Alaska, with contributions by Bull, Katharine, Cameron, Cheryl, Coombs, Michelle, Diefenbach, Angie, Lopez, Taryn, McNutt, Steve, Neal, Christina, Payne, Allison,...
