Diel and seasonal changes of dissolved oxygen an pH in relation to community metabolism of a shallow reservoir in southeast Missouri
G.D. Wylie, J.R. Jones
1987, Journal of Freshwater Ecology (4) 115-125
Diel changes of dissolved oxygen (DO) and pH were measured during 1981–1982 in Pool 1, a shallow reservoir in southeast Missouri. Diel changes in spring and fall were about half those of summer when extensive macrophyte biomass apparently had a strong influence on dynamics of DO and pH....
Stochastic model for the long-term transport of stored sediment in a river channel
Harvey M. Kelsey, Roland Lamberson, Mary Ann Madej
1987, Water Resources Research (2) 1738-1750
We develop a stochastic model for the transport of stored sediment down a river channel. The model is based on probabilities of transition of particles among four different sediment storage reservoirs, called active (often mobilized), semiactive, inactive, and stable (hardly ever mobilized). The probabilities are derived from computed sediment residence...
LEACHATE MIGRATION FROM A SOLID WASTE DISPOSAL FACILITY NEAR BISCAYNE NATIONAL PARK, SOUTH FLORIDA.
Bradley G. Waller, James L. Labowski
1987, Conference Paper
Leachate from the Dade County Solid Waste Disposal Facility (SWDF) is migrating to the east (seaward) and to the south from the currently active disposal cell. Water levels and ground-water flow directions are strongly influenced by water-management practices. The SWDF is constructed over the salt-intruded part of the highly transmissive...
Analysis of steady-state salt-water upconing with application at Truro well field, Cape Cod, Massachusetts
T. E. Reilly, M. H. Frimpter, D.R. LeBlanc, A.S. Goodman
1987, Groundwater (25) 194-206
Salt-water upconing describes the phenomenon where salt water is transported vertically upward under a well in response to pumpage in a fresh-water aquifer underlain by salt water. Sharp interface methods have been used successfully to describe the physics of upconing. A finite-element model is developed...
Unusual bed forms on the North Aleutian Shelf, Bristol Bay, Alaska
W. C. Schwab, B. F. Molnia
1987, Geo-Marine Letters (7) 207-215
Side-scan sonar records collected over an area of the North Aleutian Shelf, approximately 250 km west of the head of Bristol Bay, Alaska, identified widespread evidence of active sea floor erosion processes, including sediment transport. Thousands of sea floor depressions, many linear and some containing rippled floors, were identified in...

William R. Normark, Janet L. Morton, Stephanie L. Ross
1987, Journal of Geophysical Research B: Solid Earth (92) 11283-11290
In September 1984, the research submersible Alvin provided direct observations of three major hydrothermal vent areas along the southernmost segment of the Juan de Fuca Ridge (JFR). The submersible operations focused on specific volcanologie, structural, and hydrothermal problems that had been identified during the preceding 4 years of photographic, dredging,...

O.M. Johannessen, J.A. Johannessen, E. Svendsen, R.A. Shuchman, W. J. Campbell, E. Josberger
1987, Science (236) 427-429
Five prominent ice-edge eddies in Fram Strait on the scale of 30 to 40 kilometers were observed over deep water within 77°N to 79°N and 5°W to 3°E. The use of remote sensing, a satellite-tracked buoy, and in situ oceanographic measurements showed the presence of eddies with orbital speeds of...

D. J. Ackerman
1987, Water-Resources Investigations Report 87-4282
A map shows generalized contours of the altitude of water levels for wells completed in the Sparta-Memphis aquifer in eastern Arkansas. Most water-level measurements used in constructing the map were from the spring of 1980, but supplemental measurements from other years indicated no long-term change in water levels. Hydrographs for...

D.M. Fry, S.I. Fefer, L. Sileo
1987, Marine Pollution Bulletin (18) 339-343
Surveys of Laysan Albatross and Wedge-tailed Shearwaters on Midway and Oahu Island, Hawaii, identified a high proportion of birds with plastic in the upper gastrointestinal tract, representing hazards to the health of adult birds and their chicks. Fifty Laysan Albatross chicks were examined for plastic items lodged within the upper...

C.M. Rascher, C. T. Driscoll, N.E. Peters
1987, Biogeochemistry (3) 209-224
Decreases in pH and increases in the concentration of Al and NO3- have been observed in surface waters draining acid-sensitive regions in the northeastern U.S. during spring snowmelt. To assess the source of this acidity, we evaluated solute concentrations in snowpack, and in meltwater collected from snow and forest floor...

L. M. Nelson
1987, Water-Resources Investigations Report 86-4179
Inundation from 25-, 50-, 100-, and 500-year floods at Sunshine Point and Longmire facilities and the Longmire visitors ' center and ranger station generally is not a serious hazard as long as the existing dikes and banks of the Nisqually River and Tahoma Creek remain intact and flood capacities of...
EFFECTS OF LAND SUBSIDENCE ON FLOOD PROFILES.
M. N. Landers
1987, Conference Paper
In this study, the effects of land subsidence on water-surface elevation and depth profiles during flood conditions were investigated for a large, hypothetical, slope-controlled stream. Subsidence depressions, with a range of vertical magnitudes and areas were imposed on a hypothetical stream reach. Step-backwater computations were made to determine water-surface and...
Some effects of climate variability on hydrology in western North America
D. H. Peterson, D.R. Cayan, J. S. Dileo-Stevens, T.G. Ross
1987, Conference Paper, The influence of climate change and climatic variability on the hydrologic regime and water resources (Proceedings of the Vancouver Symposium, August 1987), IAHS Publication no. 168
The strong north-south gradient in precipitation along the West Coast makes this region an interesting laboratory for studying the influence of climate on runoff variability in general and riverine chemistry in particular. Interannual fluctuations in large-scale atmospheric circulation and associated precipitation and runoff can produce major disruptions in the "average"...

P. J. Quinterno, J.V. Gardner
1987, Journal of Foraminiferal Research (17) 132-152
We analyzed benthic foraminifers from 71 surface samples collected from the sea floor of the continental margin. One hundred and six different taxa were identified, and Q-mode factor analysis was used to identify assemblages. Six foraminiferal assemblage factors explain 94% of the variation in the data matrix. The Inner Shelf...
