The intense synchrotron radiation produced by wiggler magnets at electron storage rings provides a new source of x-rays highly suited to iodine K-edge digital subtraction angiography. The monochromaticity and tunability provide maximum sensitivity to intraarterial iodine and virtually eliminate contrast due to soft tissue and bone. Visualization of arteries, in...

A review of remote sensing and grasslands literature
G. Gray Tappan, H. C. Kinsler
1982, Cooperator Report E82-10277
Studies between 1971 and 1980 dealing with remote sensing of rangelands/grasslands in the multispectral band are summarized and evaluated. Vegetation and soil reflectance properties are described. In the majority of the studies, the effect of the reflectance of green rangelands vegetation on the reflectance from the total scene is the...
Paleomagnetic study of some Cretaceous and Tertiary sedimentary rocks of the Klamath Mountains province, California
Edward A. Mankinen, William P. Irwin
1982, Geology (10) 82-87
Paleomagnetic investigation of Cretaceous outliers and Tertiary sedimentary strata of the Klamath Mountains province, and of onlapping Cretaceous strata, has shown the rocks to be largely remagnetized. Samples studied are from the Upper Jurassic to Upper Cretaceous Great Valley sequence, Upper Cretaceous Hornbrook Formation, Eocene Montgomery Creek Formation, and Oligocene(?)...
A new look at the Saturn system: The Voyager 2 images

1982, Science (215) 504-537
Voyager 2 photography has complemented that of Voyager I in revealing many additional characteristics of Saturn and its satellites and rings. Saturn's atmosphere contains persistent oval cloud features reminiscent of features on Jupiter. Smaller irregular features track out a pattern of zonal winds that is symmetric about...
A late Pleistocene glacial chronology for the southern Brooks Range: Stratigraphic record and regional significance
T. D. Hamilton
1982, GSA Bulletin (93) 700-716
Radiocarbon dates from 11 measured sections in the Koyukuk region provide a chronology of the last Pleistocene glaciation. Glaciers were advancing strongly by 24,000 yr ago; they built moraines near the south flank of the Brooks Range, retreated briefly about 22,000 to 20,000 yr B.P., then readvanced at least one...

Diverse basalt types from Loihi seamount, Hawaii
James G. Moore, D. A. Clague, W. R. Normark
1982, Geology (10) 88-92
Loihi seamount is the southeasternmost active volcano in the Hawaiian-Emperor volcanic chain. The seamount is considered representative of the early phase of Hawaiian volcanism because of its youth, small size, and location near the melting anomaly. Seventeen dredge stations recovered transitional basalt, alkalic basalt, and basanite, in addition to the...
Ancient plate boundaries in the Bering Sea region
M. S. Marlow, Alan K. Cooper, David W. Scholl, H. McLean
1982, Geological Society, London, Special Publications (10) 201-211
Plate tectonic models of the Bering Sea suggest that the abyssal Bering Sea Basin is underlain by oceanic crust, a supposition supported by refraction and magnetic data. The oceanic crust is thought to be a remnant of the Kula(?) plate that was isolated within what is now the Bering...

Deep artesian aquifers of Sanibel and Captiva Islands, Lee County, Florida
D. H. Boggess, T.H. O’Donnell
1982, Open-File Report 82-253
Sanibel and Captiva Islands, two of the barrier islands off the lower west coast of Florida, have a resident population of about 6,000 and an additional 6,000 visitors during the peak of the tourist season. Rapid growth and extensive development in recent years have imposed progressively greater stress on the...

Hydrologic data from monitoring of saline-water intrusion in the Cape Coral area, Lee County, Florida
Daniel J. Fitzpatrick
1982, Open-File Report 82-772
As a result of declining water levels and saline-water intrusion in the Cape Coral area, the U.S. Geological Survey in cooperation with the City of Cape Coral established a monitoring well network in Cape Coral and adjacent areas in 1978-79. The network was designed to provide indication of lateral movement...

Guidelines for determining flood flow frequency: Bulletin #17B of the Hydrology Subcommittee
Interagency Advisory Committee on Water Data
1982, Bulletin 17B
In December 1967, Bulletin No. 15, "A Uniform Technique for Determining Flood Flow Frequencies," was issued by the Hydrology Committee of the Water Resources Council. The report recommended use of the Pearson Type III distribution with log transformation of the data (log-Pearson Type III distribution) as a base method for...

Liming of acidified waters: issues and research - a report of the International Liming Workshop
R. Kent Schreiber
1982, FWS/OBS 80/40.14
Acidic deposition is a problem of significant national and international concern. It is strongly suspected that acidic deposition has adversely affected aquatic resources in Scandinavia and North America. While substantial resources are being devoted to understanding the causative factors associated with surface water acidification, much less research is being conducted...

1982, Conference Paper, The reef and man: proceedings of the Fourth International Coral Reef Symposium, Manila, Philippines, 18-22 May 1981
Six of 12 core holes drilled at Looe Key Reef (24°37'18"N. 81°24'24"W) by a diver-operated coring device penetrated a spur and groove system. Drilling indicated that: (II the spurs and grooves formed over at least 5 m of carbonate reef sand: (2) the underlying Pleistocene surface is essentially flat and...
