Charles E. Wivell, Coert Olmsted, Daniel R. Steinwand, Christopher Taylor
1993, Photogrammetric Engineering and Remote Sensing (59) 527-528
Because the pixel location in a line of Synthetic Aperture Radar (SAR) image data is directly related to the distance the pixel is from the radar, terrain elevations cause large displacement errors in the geo-referenced location of the pixel. This is especially true for radar systems with small angles between...
Allogenic and autogenic controls on sedimentation in the central Sumatra basin as an analogue for Pennsylvanian coal-bearing strata in the Appalachian basin
C. Blaine Cecil, Frank T. Dulong, James C. Cobb
1993, GSA Special Papers (286) 3-22
Recent sedimentation patterns in the central Sumatra basin, Republic of Indonesia, may help to explain the cyclic stratigraphy of the Pennsylvanian System of the eastern United States. Modern influx of fluvial siliciclastic sediment to the epeiric seas of the Sunda shelf, including the Strait of Malacca, appears to be highly...
Evidence for late Holocene relative sea-level fall from reconnaissance stratigraphical studies in an area of earthquake-subsided intertidal deposits, Isla Chiloé, southern Chile
L.E. Frostick, R.J. Steel, S. Bartsch-Winkler, H. R. Schmoll
1993, Book chapter, Tectonic controls and signatures in sedimentary successions
At Río Pudeto and Quetalmahue, two estuaries along the northern shore of Isla Chiloé that subsided as much as 2 m in the great 1960 earthquake, reconnaissance stratigraphical studies reveal evidence of a regressive, nearshore marine sequence. The intertidal deposits include a peat-bearing, high-intertidal marsh sequence as thick as...

1993, Earthquakes & Volcanoes (USGS) (24) 270-291
When the seismograph began to record the violent earth-shaking caused by yet another eruption of the Nevado del Ruiz volcano in Colombia, no one thought that a few hours later more than 23,000 people would be dead, killed by lahars (volcanic debris flows) in towns and villages several tens of...
Patterns of orographic uplift in the Sierra Nevada and their relationship to upper-level atmospheric circulation
Edward Aguado, Daniel R. Cayan, Brian D. Reece, Larry Riddle
1993, Conference Paper, Proceedings of the ninth annual pacific climate (PACLIM) workshop
We examine monthly and seasonal patterns of precipitation across various elevations of the eastern Central Valley of California and the Sierra Nevada. A measure of the strength of the orographic effect called the “precipitation ratio” is calculated, and we separate months into four groups based on being wet or dry...
Restoration ecology: longterm evaluation as an essential feature of rehabilitation
John E. Gannon
1993, Buffalo Environmental Law Journal (1) 267-277
In its brief existence as a recognized scientific discipline, restoration ecology has focused almost exclusively on terrestrial and wetland habitat. As a consequence, aquatic restoration and rehabilitation, an important component of restoration ecology is a relatively new discipline. This article examines the ecosystem approach to rehabilitation of the...

Brown coal maceral distributions in a modern domed tropical Indonesian peat and a comparison with maceral distributions in Middle Pennsylvanian–age Appalachian bituminous coal beds
William C. Grady, Cortland F. Eble, Sandra G. Neuzil
1993, Special Paper of the Geological Society of America (286) 63-82
Analyses of modern Indonesian peat samples reveal that the optical characteristics of peat constituents are consistent with the characteristics of macerals observed in brown coal and, as found by previous workers, brown-coal maceral terminology can be used in the analysis of modern peat. A core from the margin and...
Reconnaissance investigation of water quality, bottom sediment, and biota associated with irrigation drainage in the Pine River Project area, Southern Ute Indian Reservation, southwestern Colorado and northwestern New Mexico, 1988-89
D. L. Butler, R. P. Krueger, B. C. Osmundson, A. L. Thompson, J. J. Formea, D. W. Wickman
1993, Water-Resources Investigations Report 92-4188
During 1988-89, water, bottom sediment, biota, soil, and plants were sampled for a reconnaissance investigation of the Pine River Project area in southwestern Colorado. Irrigation drainage does not seem to be a major source of dissolved solids in streams. Concentrations of manganese, mercury, and selenium exceeded drinking-water regulations in some...
Updating our thinking on the role of human activity in wolf recovery
L. David Mech
1993, Research Information Bulletin 57
It is common for land managers and administrators involved in wolf (Canis lupus) management to assume that human development within wolf habitat is a hindrance to wolf recovery. Thus, researchers are often asked questions like We are planning to build a new dock and parking area on Wolf Lake; how...

Large-scale deformation associated with ridge subduction
E.L. Geist, M. A. Fisher, D.W. Scholl
1993, Geophysical Journal International (115) 344-366
Continuum models are used to investigate the large-scale deformation associated with the subduction of aseismic ridges. Formulated in the horizontal plane using thin viscous sheet theory, these models measure the horizontal transmission of stress through the arc lithosphere accompanying ridge subduction. Modelling was used to compare the Tonga arc...
