Mapping nuclear craters on Enewetak Atoll, Marshall Islands
John C. Hampson
1986, Conference Paper, Proceedings International Symposium on Marine Positioning
In 1984, the U.S. Geological Survey conducted a detailed geologic analysis of two nuclear test craters at Enewetak Atoll, Marshall Islands, on behalf of the Defense Nuclear Agency. A multidisciplinary task force mapped the morphology, surface character, and subsurface structure of two craters, OAK and KOA. The field mapping techniques include...
Processing techniques for the production of an experimental computer-generated shaded-relief map
Damon D. Judd
1986, American Cartographer (13) 72-79
An experimental computer-generated shaded-relief map of a topographic quadrangle of Nome, Alaska, at 1:1,000,000 scale was created to demonstrate current capabilities of map production. This paper describes the techniques used to produce the map product. The data consisted of forty-eight 1° by 1° blocks of resampled digital elevation model (DEM) data....
Vegetation mapping of Nowitna National Wildlife Refuge, Alaska using Landsat MSS digital data
Stephen S. Talbot, Carl J. Markon
1986, Photogrammetric Engineering and Remote Sensing (52) 791-799
A Landsat-derived vegetation map was prepared for Nowitna National Wildlife Refuge. The refuge lies within the middle boreal subzone of north central Alaska. Seven major vegetation classes and sixteen subclasses were recognized: forest (closed needleleaf, open needleleaf, needleleaf woodland, mixed, and broadleaf); broadleaf scrub (lowland, alluvial, subalpine); dwarf scrub (prostrate...
Application of the Flory-Huggins theory to the solubility of solids in glyceryl trioleate
Cary T. Chiou, Milton Manes
1986, Journal of the Chemical Society, Faraday Transactions I (82) 243-246
The conventional thermodynamic deviation for ideal solid–liquid solubilities is modified by substituting the Flory–Huggins model for Raoult's law. A comparison of published data for eleven solides in glyceryl trioleate with the predictions of the conventional and modified equations shows that the significantly higher athermal solubilities from the modified...
Alaska goose populations: Past, present and future
James G. King, Dirk V. Derksen
1986, Conference Paper, Transactions of the fifty-first North American wildlife and natural resources conference
Many people think Alaska remains a pristine wilderness and that wildlife populations are still at prehistoric levels. This very likely is not true for the 11 species and subspecies of geese that nest in Alaska. Large, widely dispersed populations of geese were observed near the turn of the century. Even...
Rb-Sr, K-Ar, and stable isotope evidence for the ages and sources of fluid components of gold-bearing quartz veins in the northern Sierra Nevada foothills metamorphic belt, California
J.K. Bohlke, R. W. Kistler
1986, Economic Geology (81) 296-322
Gold-bearing quartz veins occur in and near major fault zones in deformed oceanic and island-arc rocks west of the main outcrop of the Sierra Nevada composite batholith. Veins typically occupy minor reverse faults that crosscut blueschist to amphibolite-grade metamorphic rocks whose metamorphic ages range from early Paleozoic to Jurassic. Vein...
Late Cretaceous stratigraphy, deformation and intrusion in the Madison Range of southwestern Montana ( USA).
R. G. Tysdal, R. F. Marvin, E. Dewitt
1986, Geological Society of America Bulletin (97) 859-868
Dating of orogenic rock units in the central part of the Madison Range shows that Laramide deformation was virtually completed by the end of the Cretaceous. Early Campanian K-Ar dates of about 79 m.y. were obtained from welded tuffs in the basal part of the Livingston Formation, a volcanic and...
Research on polar bears in Alaska, 1983-1985
Steven C. Amstrup
1986, Conference Paper, Polar bears: Proceedings of the ninth working meeting of the IUCN/SSC Polar Bear Specialist Group
Research on the ecology and status of polar bear populations in Alaska has continued since 1967. Research was a joint U.S. Fish and Wildlife Service/Alaska Department of Fish and Game effort until passage of the Marine Mammal Protection Act in 1972, and has been largely a Federal effort since then....
Inductively coupled plasma atomic fluorescence spectrometric determination of cadmium, copper, iron, lead, manganese and zinc
R. F. Sanzolone
1986, Journal of Analytical Atomic Spectrometry (1) 343-347
An inductively coupled plasma atomic fluorescence spectrometric method is described for the determination of six elements in a variety of geological materials. Sixteen reference materials are analysed by this technique to demonstrate its use in geochemical exploration. Samples are decomposed with nitric, hydrofluoric and hydrochloric acids, and the residue dissolved...
Digital image measurement of the area and anatomical structure of tree rings
Thomas M. Yanosky, Charles J. Robinove
1986, Canadian Journal of Botany (64) 2896-2902
A microcomputer coupled to a video digitizer was used to develop methods for measuring areas of tree rings and for delineating and measuring microscopic anatomical features. Digitally imaged areas of individual rings of a loblolly pine cross section were within 2.6% of areas measured with a planimeter and were more...
Aqueous geochemistry and diagenesis in the eastern Snake River Plain aquifer system, Idaho
Warren W. Wood, Walton H. Low
1986, Bulletin (97) 1456-1466
Water budget and isotopic analyses of water in the eastern Snake River Plain aquifer system confirm that most, if not all, of the water is local meteoric in origin. Solute mass-balance arguments suggest that ∼5 × 109 moles of calcite and 2.6 × 109 moles of silica are precipitated annually...
Influence of irrigation on salinity and nitrate in a stream-aquifer system
Leonard F. Konikow, M.A. Person
1986, Conference Paper, Conjunctive water use: understanding and managing surfacewater-groundwater interactions
Changes in salinity and nitrate concentration in groundwater and surface water in the semiarid Arkansas River valley of southeastern Colorado, USA were related primarily to irrigation practices. Water is applied to fields by flood irrigation through ditches and furrows. Irrigation water is derived in nearly equal amounts from surface water...

Hydrogeologic framework of the Floridan aquifer system in Florida and in parts of Georgia, Alabama, and South Carolina
James A. Miller
1986, Professional Paper 1403-B
The Floridan aquifer system of the Southeastern United States is comprised of a thick sequence of carbonate rocks that are mostly of Paleocene to early Miocene age and that are hydraulically connected in varying degrees. The aquifer system consists of a single vertically continuous permeable unit updip and of two...
A new view for resource managers
Robert H. Haas
1986, Rangelands (8) 99-102
In decades past, the rancher depended upon reports from cowboys to gather information he needed to make management decisions. Today, the vast open ranges of the cowboy era are mostly gone in the United States-fenced into pastures, paddocks, or fields that are now discrete management units. But fencing in the...
Effect of seasonally changing tissue weight on trace metal concentrations in the bivalve Macoma balthica in San Francisco Bay
Daniel J. Cain, Samuel N. Luoma
1986, Marine Ecology Progress Series (28) 209-217
The influence of seasonal changes in the weight of soft tissues on temporal fluctuations in tissue concentrations of Cu and Zn was examined in 4 populations of the clam Macoma balthica sampled in San Francisco Bay for a period of 2 to 5 yr. Fluctuations in metal concentration expected from...
Interannual variability in biochemistry of partially mixed estuaries: Dissolved silicate cycles in northern San Francisco Bay
David H. Peterson, Daniel R. Cayan, John F. Festa
Douglas A. Wolfe, editor(s)
1986, Book chapter, Estuarine variability
Much of the interannual variability in partially mixed estuaries in dissolved inorganic nutrient and dissolved oxygen patterns results from an enhancement or reduction of their annual cycle (generally via climatic forcing). In northern San Francisco Bay estuary the annual cycle of dissolved silicate supply peaks in spring and the effect...

Ground Water
Water Resources Division, U.S. Geological Survey
1986, Report
Some water underlies the Earth's surface almost everywhere, beneath hills, mountains,plains, and deserts. It's not always accessible, or fresh enough for use without treatment, and it's sometimes difficult to locate or to measure and descri be. This water may occur close to the land surface, as in a marsh, or...
