Use of remote sensing for monitoring deforestation in tropical and subtropical latitudes
J. J. Talbot, Lawrence R. Pettinger
1981, Ciencia Interamericana (21) 63-71
Of the three types of remotely sensed data discussed here, Landsat data offers the greatest potential for monitoring broad changes in extensive tropical forest environments because of its low-cost, synoptic, repetitive coverage. Scientists from developing countries can choose from a variety of Landsat data classification techniques, thus enabling each country...

EROS: A space program for Earth resources
G.G. Metz, P.J. Wiepking
1980, Report
Within the technology of the space age lies a key to increased knowledge about the resources and environment of the Earth. This key is remote sensing detecting the nature of an object without actually touching it. Although the photographic camera is the most familiar remote-sensing device, other instrument systems, such...
Storm runoff as related to urbanization in the Portland, Oregon-Vancouver, Washington Area
Antonius Laenen
1980, Water-Resources Investigations Report 80-689
A series of equations was developed to provide a better method of determining flood frequencies in the Portland-Vancouver urban area than is now available. The resulting regression equations can be used to compute peak discharge and storm runoff with a standard error of estimate of approximately 30 percent. Basins used...
Estimating the size and trend of the California condor population, 1965-1978
S.R. Wilbur
1980, California Fish and Game (66) 40-48
During 1965-1978, three principal methods were used to measure the size and trend of the California Condor (Gymnogyps californianus) population. An October survey conducted by as many as 136 observers had limited value because daily activity patterns of condors were unpredictable and because analysis of results could not be...
Computer simulation models as tools for identifying research needs: A black duck population model
J.K. Ringelman, J. R. Longcore
1980, Transactions of the Northeast Section of the Wildlife Society, Annual Fish and Wildlife Conference (37) 182-193
Existing data on the mortality and production rates of the black duck (Anas rubripes) were used to construct a WATFIV computer simulation model. The yearly cycle was divided into 8 phases: hunting, wintering, reproductive, molt, post-molt, and juvenile dispersal mortality, and production from original and renesting attempts. The program computes...
Waterfowl production estimates on forested wetlands from pair and brood counts
R.E. Kirby
1980, Wildlife Society Bulletin (8) 273-278
Waterfowl pair and brood counts and estimates of total brood utilization were obtained from 10 beaver (Castor canadensis) flowages in north-central Minnesota and compared with rank correlation techniques. Summing the data for each species, correlation between pair and brood censuses was significant ( p = 0.8304, P < 0.025). Similarly,...
Survey of resampling techniques using MSS and synthetic imagery
Brian P. Bauer
1980, Report
The objective of this survey is to investigate the methods of interpolation and deconvolution for image restoration The methods evaluated are nearest neighbor, bilinear interpolation, cubic convolution, and two-dimensional deconvolution. The effects of these restoration methods are demonstrated using Landsat multispectral scanner (MSS) data and synthetic imagery. The effect of these...

1980, FWS/OBS 80/39
Summary: This report discusses the development of a coastal and marine bird data base at the Migratory Bird and Habitat Research Laboratory. The system is compared with other data bases, and suggestions for future development, such as possible adaptations for other taxonomic groups, are included....
Digital terrain tapes: user guide
Water Resources Division, U.S. Geological Survey
1980, Report
DMATC's digital terrain tapes are a by-product of the agency's efforts to streamline the production of raised-relief maps. In the early 1960's DMATC developed the Digital Graphics Recorder (DGR) system that introduced new digitizing techniques and processing methods into the field of three-dimensional mapping. The DGR system consisted of an...

Biostratigraphic correlation of Pleistocene marine deposits and sea levels, Atlantic coastal plain of the southeastern United States
T. M. Cronin
1980, Quaternary Research (13) 213-229
Marine ostracodes from 50 localities were studied to determine the age and elevation of Pleistocene sea levels in the Atlantic coastal plain from Maryland to northern Florida. Using ostracode taxon and concurrent ranges, published planktic biostratigraphic, paleomagnetic, and radiometric data, ostracode assemblage zones representing early (1.8-1.0 my), middle (0.7-0.4 my),...
