Mark J. Johnsson, Kevin R. Evans, H. R. Marshall
1999, Data Series 54
This CD-ROM is an updated re-release of three USGS publications on the thermal maturity of sedimentary rocks in Alaska: 1) Vitrinite reflectance and conodont color alteration index data from Alaska; data to accompany the thermal maturity map of Alaska; Open-File Report 92-409 (1992), version 1.1 (revised 1999), 2) Generalized thermal...
Sea-floor images and data from multibeam surveys in San Francisco Bay, Southern California, Hawaii, the Gulf of Mexico, and Lake Tahoe, California-Nevada
Peter Dartnell, James V. Gardiner
1999, Data Series 55
Accurate base maps are a prerequisite for any geologic study, regardless of the objectives. Land-based studies commonly utilize aerial photographs, USGS 7.5-minute quadrangle maps, and satellite images as base maps. Until now, studies that involve the ocean floor have been at a disadvantage due to an almost complete lack of...

Influence of externally attached transmitters on the swimming performance of juvenile white sturgeon
T.D. Counihan, C.N. Frost
1999, Transactions of the American Fisheries Society (128) 965-970
We measured the critical swimming speed of juvenile white sturgeons Acipenser transmontanus equipped with externally attached dummy ultrasonic transmitters and of untagged control fish in the laboratory. White sturgeons ranging from 31.9 to 37.0 cm fork length were subjected to one of three treatments: Control (handled but not tagged),...

Biomass of coastal cutthroat trout in unlogged and previously clear-cut basins in the central Coast Range of Oregon
P.J. Connolly, J.D. Hall
1999, Transactions of the American Fisheries Society (128) 890-899
Populations of coastal cutthroat trout Oncorhynchus clarki clarki were sampled in 16 Oregon headwater streams during 1991–1993. These streams were above upstream migration barriers and distributed among basins that had been logged 20–30 and 40–60 years ago and basins that had not been logged but had burned 125–150 years...
Geologic map of the Scotts Mills, Silverton, and Stayton Northeast 7.5 minute quadrangles, Northwest Oregon: A digital database
Terry Tolan, Marvin Beeson, Karen L. Wheeler
1999, Open-File Report 99-141
The Scotts Mills, Silverton, and Stayton NE 7.5 minute quadrangles are situated along the eastern margin of the Willamette Valley and adjacent lower foothills (Waldo and Silverton Hills) of the Cascade Range (Fig. 1). The terrain within this area is of low to moderate relief, ranging from 100 to more...

An evaluation of sand and gravel resources in and near the Prescott National Forest in the Verde Valley, Arizona, with a section on evaluation of sand and gravel resources using selected engineering variables
Leslie J. Cox, James D. Bliss, Robert J. Miller
1999, Open-File Report 99-127
This study was based on available published literature. Although no field investigation was conducted in the Prescott National Forest to the west of the Verde River, a field investigation was conducted in the summer of 1994 by this author on the Coconino National Forest, to the east of the Verde...

The effect of dietary protein and lipid source on dorsal fin erosion rainbow trout, Oncorhynchus mykiss
Frederic T. Barrows, William A. Lellis
1999, Aquaculture (180) 167-175
A study was conducted to determine the effect of dietary protein and lipid source on dorsal fin erosion in rainbow trout. Seven diets were each fed to four replicate lots of 300 first-feeding fry cultured in 75 l aluminum troughs for 8 weeks. Two basal diets were manufactured with approximately...

Bathymetric change off the Washington-Oregon coast
Ann E. Gibbs, Guy R. Gelfenbaum, Nicholas C. Kraus, William G. McDougal
1999, Conference Paper, 4th international symposium on Coastal engineering and science of coastal sediment processes; Scales of coastal sediment motion and geomorphic change
Historical hydrographic data from the Washington/Oregon shelf are compared for the first time to identify bathymetric change on a regional scale. Offshore data sets exist for four time periods: 1800s, pre-1950s, post-1950s, and 1990s. Data from only two time periods, 1868-87 and 1926-27, cover the...
Fishes of Missouri River, chute, and flood plain habitats: Chapter 4 in Initial biotic survey of Lisbon Bottom, Big Muddy National Fish and Wildlife Refuge
Joanne Grady, Jim Milligan, Duane Chapman, Ellen A. Ehrhardt, Douglas J. Dieterman, David L. Galat, John Hooker, John Kubisiak, Aaron DeLonay, Edward E. Little, Jack Robinson, John Tibbs
1999, Biological Science Report 2000-0001-4
The Lisbon Bottom Unit of the Big Muddy National Fish and Wildlife Refuge (Refuge) is approximately 2,200 acres and is the first complete unit of the Refuge. Primary objectives of the Refuge are to create and restore diverse riverine aquatic habitats and reconnect the Missouri River to its flood plain...
Short-term physiological responses of wild and hatchery-produced red drum during angling
E.A. Gallman, J. Jeffery Isely, J.R. Tomasso, T.I.J. Smith
1999, North American Journal of Fisheries Management (19) 833-836
Serum cortisol concentrations, plasma glucose concentrations, plasma lactate concentrations, and plasma osmolalities increased in red drum Sciaenops ocellatus (26.0-65.5 cm total length) during angling in estuarine waters (17-33 g/L salinity, 21-31??C). Angling time varied from as fast as possible (10 s) to the point when fish ceased resisting (up to...

Evaluation of landslide hazards with ground-penetrating radar, Lake Michigan coast
Walter A. Barnhardt, Bruce E. Jaffe, Robert Kayen
1999, Conference Paper, 4th international symposium on Coastal engineering and science of coastal sediment processes
Ground-penetrating radar (GPR) and boreholes were used to investigate a landslide-prone bluff at Sleeping Bear Dunes National Lakeshore on the northeastern coast of Lake Michigan. Based on borehole observations, sediment underlying the area is homogeneous, consisting of well-sorted, medium to coarse sand. GPR...

The modeler's influence on calculated solubilities for performance assessments at the Aspo Hard-rock Laboratory
A.T. Ernren, R. Arthur, P. D. Glynn, J. McMurry
1999, Materials Research Society Symposium - Proceedings (556)
Four researchers were asked to provide independent modeled estimates of the solubility of a radionuclide solid phase, specifically Pu(OH)4, under five specified sets of conditions. The objectives of the study were to assess the variability in the results obtained and to determine the primary causes for this variability.In the exercise,...

We assessed DNA repair and resistance to solar radiation in eggs of members of the western spotted frog complex (Rana pretiosa and R. luteiventris), species whose populations are suffering severe range reductions and declines. Specifically, we measured the activity of photoreactivating enzyme (photolyase) in oocytes of spotted frogs. In some species, photoreactivation...
