Forest to agriculture conversion in southern Belize: Implications for migrant land birds
J.P. Spruce, B.A. Dowell, C.S. Robbins, S.A. Sader
Jamie K. Doyle, John Schelhas, editor(s)
1993, Book chapter, Forest Remnants in the Tropical Landscape: Benefits and Policy Implications.
Central America offers a suite of neotropical habitats vital to overwintering migrant land birds. The recent decline of many forest dwelling avian migrants is believed to be related in part to neotropical deforestation and land use change. However, spatio-temporal trends in neotropical habitat availability and avian migrant habitat use are...

Raster profile development for the spatial data transfer standard
John A. Szemraj
1993, Pecora 12 Symposium 267-272
The Spatial Data Transfer Standard (SDTS), recently approved as Federal Information Processing Standard (FIPS) Publication 173, is designed to transfer various types of spatial data. Implementing all of the standard's options at one time is impractical. Profiles, or limited subsets of the SDTS, are the mechanisms by which...

1993, Remote Sensing of Environment (45) 165-175
Ground data from the Central Plains Experimental Range in northeast Colorado and Landsat satellite images of that area acquired in August 1989, June 1990, and September 1990 were used to evaluate the level of association that can be expected from a univariate model relating spectrally derived vegetation indices (difference, ratio,...
Sediment export by ice rafting from a coastal Polynya, Arctic Alaska, U.S.A.
Erk Reimnitz, Michael McCormick, Kristin McDougall-Reid, Elisabeth M. Brouwers
1993, Arctic and Alpine Research (25) 83-98
Strong offshore winds in early 1989 produced a shore polynya that reached along the entire north coast of Alaska and eastward beyond the mouth of the Mackenzie River in Canada. From January through April, this open water periodically exposed the shelf to sediment entrainment by suspension freezing. This process requires...
Velocity measurements and changes in position of Thwaites Glacier/iceberg tongue from aerial photography, Landsat images and NOAA AVHRR data
Jane G. Ferrigno, Baerbel K. Lucchitta, A. L. Mullinsallison, Robert J. Allen, W. G. Gould
1993, Annals of Glaciology (17) 239-244
The Thwaites Glacier/iceberg tongue complex has been a significant feature of the Antarctic coastline for at least 50 years. In 1986, major changes began to occur in this area. Fast ice melted and several icebergs calved from the base of the iceberg tongue and the terminus of Thwaites Glacier. The...
Surficial geology of the Safsaf region, south-central Egypt, derived from remote-sensing and field data
P. A. Davis, C. S. Breed, J.F. McCauley, G. G. Schaber
1993, Remote Sensing of Environment (46) 183-203
We used a decorrelation-stretched image of Landsat Thematic Mapper (TM) Bands 1, 4, and 7 and field data to map and describe the main surficial units in the hyperarid Safsaf region in south-central Egypt. We show that the near-infrared bands on Landsat TM, which are sensitive to very subtle changes...
Oblique synoptic images, produced from digital data, display strong evidence of a "new" caldera in southwestern Guatemala
W. Duffield, G. Heiken, D. Foley, A. McEwen
1993, Journal of Volcanology and Geothermal Research (55) 217-224
The synoptic view of broad regions of the Earth's surface as displayed in Landsat and other satellite images has greatly aided in the recognition of calderas, ignimbrite plateaus and other geologic landforms. Remote-sensing images that include visual representation of depth are an even more powerful tool for geologic interpretation of...
Antarctic glacier-tongue velocities from Landsat images: First results
Baerbel K. Lucchitta, K.F. Mullins, A.L. Allison, Jane G. Ferrigno
1993, Annals of Glaciology (17) 356-366
We measured the velocities of six glacier tongues and a few tongues within ice shelves distributed around the Antarctic coastline by determining the displacement of crevasse patterns seen on sequential Landsat images. The velocities range from less than 0.2 km a−1 for East Antarctic ice-shelf tongues to more than 2.5...

J. R. Wilford, C. F. Pain, J. C. Dohrenwend
1992, Exploration Geophysics (23) 441-445
Airborne gamma-ray spectrometric data (400-m line spacing), gathered for the National Geoscience Mapping Accord North Queensland Project, has proved invaluable for differentiating regolith types based on their potassium, thorium and uranium signatures. The ability of the gamma-ray signal to penetrate the vegetation cover and as much as 40 cm below...
