Discovery of a Late Triassic basin north of Boston and some implications as to post-Paleozoic tectonics in northeastern Massachusetts (USA)
Clifford A. Kaye
1983, American Journal of Science (283) 1060-1079
As deduced from various data the Triassic-Jurassic Middleton basin-trends NE and is probably approx 5.7km in length and no >0.5km in width. Two sets of dikes which have been K/Ar dated as Late Triassic-Early Jurassic have the same NNE strikes as strike-slip faults. There are indications that a tectonic event...

A gravity survey of the Jiddah area between lat 21°23' and 21°48' N., long 39°03' and 39°20' E., carried out in early 1977, covers an area of 744 km2 and includes 215 stations, at an average spacing of 1.9 km. The resulting simple Bouguer gravity anomaly map shows a series...
Precision of geodolite surveys: A reply to Jackson and Cheng
James C. Savage, W.H. Prescott
1983, Journal of Geophysical Research B: Solid Earth (88) 10478-10484
Jackson and Cheng have suggested that the changes in areal dilatation measured in Geodolite surveys by the U.S. Geological Survey may be simply an artifact of the measuring system. Although systematic error could conceivably account for the observed excursions in dilatation, we maintain that the specific criticisms by Jackson and...
Rhodamine-WT dye losses in a mountain stream environment
Kenneth E. Bencala, Ronald E. Rathburn, Alan P. Jackman, Vance C. Kennedy, Gary W. Zellweger, Ronald J. Avanzino
1983, Journal of the American Water Resources Association (19) 943-950
A significant fraction of rhodamine WT dye was lost during a short term multitracer injection experiment in a mountain stream environment. The conservative anion chloride and the sorbing cation lithium were concurrently injected. In-stream rhodamine WT concentrations were as low as 45 percent of that expected, based on chloride data....

R. H. Haas, F. A. Waltz
1983, Conference Paper, Pecora VIII Symposium
The U.S. Geological Survey EROS Data Center evaluated the utility of Landsat Thematic Mapper (TM) date for natural resource assessment, emphasizing manual interpretation and digital classification of the data for U.S. Department of the Interior applications. Substantially more information was derived from TM data than from Landsat Multispectral Scanner...
Thematic mapper: detailed radiometric and geometric characteristics
Hugh Kieffer
1983, Pecora VIII Symposium 75-75
Those radiometric characteristics of the Landsat 4 Thematic Mapper (TM) that can be established without absolute calibration of spectral data have been examined. Subscenes of radiometric all raw data (B-data) were examined on an individual detector basis: areas of uniform radiance were used to characterize subtle radiometric differences and...

1983, Pecora VIII Symposium 28-30
The U.S. Geological Survey (USGS) and the Department of the Interior (DOI) were among the earliest to recognize the potential applications of satellite land remote sensing for management of the country's land and water resources…not only as a user but also as a program participant responsible for final data processing,...
Some observations on the use of discriminant analysis in ecology
Byron K. Williams
1983, Ecology (64) 1283-1291
The application of discriminant analysis in ecological investigations is discussed. The appropriate statistical assumptions for discriminant are illustrated, and both classification and group separation approaches are outlined. Three assumptions that are crucial in ecological studies are discussed at length, and the consequences of their violation are developed. These assumptions are:...

1983, Science (221) 1383-1385
The monitoring of gas emissions from Mount St. Helens includes daily airborne measurements of sulfur dioxide in the volcanic plume and monthly sampling of gases from crater fumaroles. The composition of the fumarolic gases has changed slightly since 1980: the water content increased from 90 to 98 percent, and the...

1983, Marine Micropaleontology (8) 89-119
Epibathyal ostracodes from the Florida-Hatteras slope, the Blake Plateau and the Straits of Florida were studied to determine the relationship of numerous genera and species to bottom-water environmental conditions such as dissolved oxygen and bottom-water temperatures. From a total of 100 samples, 44 samples evenly distributed between 200 and 1100...
Density estimation of small-mammal populations using a trapping web and distance sampling methods
David R. Anderson, Kenneth P. Burnham, Gary C. White, David L. Otis
1983, Ecology (64) 674-680
Distance sampling methodology is adapted to enable animal density (number per unit of area) to be estimated from capture-recapture and removal data. A trapping web design provides the link between capture data and distance sampling theory. The estimator of density is D = Mt+1f(0), where Mt+1 is the...
Organochlorine pesticides and PCB's: A continuing problem for the 1980s
W. James Fleming, D. R. Clark Jr., Charles J. Henny
1983, Transactions of the North American Wildlife and Natural Resources Conference (48) 186-199
In general. decreases in OC contamination in North America are unmistakable. This is documented by the NPMP. but. more importantly. it is borne out by improvements in the reproduction and population status of the brown pelican. bald eagle, peregrine falcon, and osprey. However, some OC contamination still persists, and several...
Airborne biogeophysical mapping of hidden mineral deposits
William Collins, Sheng-Huei Chang, G. L. Raines, Frank C. Canney, Roger P. Ashley
1983, Economic Geology (78) 737-749
Airborne survey techniques have been developed to detect and map forest canopies affected by metal-induced stress. A high spectral resolution airborne spectroradiometer system, used over a known forest-covered copper soil anomaly, has revealed previously unknown spectral changes in the near-infrared chlorophyll absorption spectrum. The metal-induced spectral shifts have subsequently been...
The relationship between harvest and survival rates of mallards: A straightforward approach with partitioned data sets
James D. Nichols, James E. Hines
1983, Journal of Wildlife Management (47) 334-348
We randomly partitioned mallard (Anas platyrhynchos) bandings and recoveries from each of a number of selected reference areas into 2 groups and estimated survival and harvest rates for each area and group. This procedure produced independent vectors of survival- and harvest-rate estimates, which were used to test the general hypothesis...

D.P. Adam, G. James West
1983, Science (219) 168-170
Modern pollen surface samples from six lake and marsh sites in the northern California Coast Ranges establish a linear relation between elevation and the oak/(oak + pine) pollen ratio. Modern temperature and precipitation lapse rates were used to convert variations in the pollen ratio into temperature and...

T. L. Vallier, Walter E. Dean, David K. Rea, Jorn Thiede
1983, GSA Bulletin (94) 1289-1307
Cores from four Deep Sea Drilling Project (DSDP) sites (310, 464, 465, and 466) and seismic-reflection profiles provide data that are used to interpret the geological evolution and paleoenvironments of Hess Rise, a prominent oceanic plateau in the central North Pacific Ocean. Hess Rise apparently formed in the Southern Hemisphere...
