Seafloor habitat mapping and classification in Glacier Bay, Alaska: Phase 1 & 2 1996-2004
Philip N. Hooge, Paul R. Carlson, Jennifer Mondragon, Lisa L. Etherington, G.R. Cochran
2004, Report
Glacier Bay is a diverse fjord ecosystem with multiple sills, numerous tidewater glaciers and a highly complex oceanographic system. The Bay was completely glaciated prior to the 1700’s and subsequently experienced the fastest glacial retreat recorded in historical times. Currently, some of the highest sedimentation rates ever observed occur in...
Acidity and Alkalinity in mine drainage: Practical considerations
III Cravotta, Carl S. Kirby
2004, Conference Paper, Proceedings America Society of Mining and Reclamation
In this paper, we emphasize that the Standard Method hot peroxide treatment procedure for acidity determination (hot acidity) directly measures net acidity or net alkalinity, but that more than one water-quality measure can be useful as a measure of the severity of acid mine drainage. We demonstrate that the hot...
Strength and acoustic properties of Ottawa sand containing laboratory-formed methane gas hydrate
William J. Winters, William F. Waite, David H. Mason
2004, Book chapter, Advances in the study of gas hydrates
Although gas hydrate occurs in a wide variety of sediment types and is present and even pervasive at some locations on continental margins, little is known about how it forms naturally. Physical properties of the resultant gas hydrate-sediment mixtures, data needed for input into models that predict location and quantity...
Analysis of summer 2002 melt extent on the Greenland ice sheet using MODIS and SSM/I data
D. K. Hall, R.S. Williams, K. Steffen, Janet Y.L. Chien
2004, Conference Paper, IGARSS '04 Proceedings
Previous work has shown that the summer of 2002 had the greatest area of snow melt extent on the Greenland ice sheet ever recorded using passive-microwave data. In this paper, we compare the 0deg isotherm derived from the Moderate-Resolution Imaging Spectroradiometer (MODIS) instrument, with Special Sensor Microwave/Imager (SSM/I)-derived melt, at...

Weathering of the meade peak phosphatic shale member, phosphoria formation: Observations based on uranium and its decay products
Robert A. Zielinski, James R. Budahn, Richard I. Grauch, J. B. Paces, K. R. Simmons
2004, Book chapter, Handbook of exploration and environmental geochemistry
Variably weathered outcrop samples of the Meade Peak Phosphatic Shale Member of the Phosphoria Formation have 5-10% of the contained uranium (U) in a form readily extractable by 0.1 M sodium bicarbonate. Fission track radiography of outcrop samples and other less-weathered channel and core samples indicate that this mobile fraction...
User's Guide for the MapImage Reprojection Software Package, Version 1.01
Michael P. Finn, Jason R. Trent
2004, Open-File Report 2004-1394
Scientists routinely accomplish small-scale geospatial modeling in the raster domain, using high-resolution datasets (such as 30-m data) for large parts of continents and low-resolution to high-resolution datasets for the entire globe. Recently, Usery and others (2003a) expanded on the previously limited empirical work with real geographic data by compiling and...

Book review: Earth’s magnetism in the age of sail
Jeffrey J. Love
2004, Physics of the Earth and Planetary Interiors (147) 354-364
For many centuries, the source, behavior, and even the essential nature of geomagnetism were enigmatic. Despite this, the effect of geomagnetism was familiar, by imparting a directional preference on the magnetized needle of the compass and providing a useful, if somewhat annoyingly complicated, reference for navigators. Although the compass seems...
Fluctuations in a metapopulation of nesting four-toed salamanders, Hemidactylium scutatum, in the Great Smoky Mountains National Park, USA, 1999-2003
Jeffrey D. Corser, C.K. Dodd Jr.
2004, Natural Areas Journal (24) 135-140
We tested two predictions associated with the hypothesis that certain populations of pond-breeding amphibians are structured into metapopulations using minimum relative abundance estimates of nesting four-toed salamanders (Hemidactylium scutatum Schlegel) from 11 different ponds in the Great Smoky Mountains National Park. Coefficients of variation (CV) for counts at individual ponds...

Inversion of data from electrical resistivity imaging surveys in water-covered areas
M. H. Loke, John W. Lane Jr.
2004, Exploration Geophysics (35) 266-271
Electrical resistivity imaging surveys widely used in many environmental and engineering studies have also been conducted in water-covered areas. Surveys in water-covered areas include conventional surveys using multi-electrode resistivity systems where part of the survey line crosses a river or stream, and surveys conducted entirely within a water-covered environment. Surveys...

Yariv Hamiel, Yunfeng Liu, V. Lyakhovsky, Yehuda Ben-Zion, David Lockner
2004, Geophysical Journal International (159) 1155-1165
A viscoelastic damage rheology model is presented that provides a generalization of Maxwell viscoelasticity to a non-linear continuum mechanics framework incorporating material degradation and recovery, transition from stable to unstable fracturing and gradual accumulation of non-reversible deformation. The model is a further development of the damage rheology framework of Lyakhovsky et...
