Rapid response to the onset of volcanic activity allows for the early assessment of hazard and risk [Tilling, 1989]. Data from remote volcanoes and volcanoes in countries with poor communication infrastructure can only be obtained via remote sensing [Harris et al., 2000]. By linking notifications of activity from ground-based and...

B. J. Buratti, Christophe Sotin, R. H. Brown, M.D. Hicks, R. N. Clark, J. A. Mosher, T. B. McCord, R. Jaumann, K. H. Baines, P. D. Nicholson, T. Momary, D.P. Simonelli, B. Sicardy
2006, Planetary and Space Science (54) 1498-1509
Cassini observations of the surface of Titan offer unprecedented views of its surface through atmospheric windows in the 1-5 ??m region. Images obtained in windows for which the haze opacity is low can be used to derive quantitative photometric parameters such as albedo and albedo distribution, and physical properties such...

Springs along the south rim of the Grand Canyon, Arizona, are important ecological and cultural resources in Grand Canyon National Park and are discharge points for regional and local aquifers of the Coconino Plateau. This study evaluated the applicability of electrical resistance (ER) sensors for measuring diffuse, low-stage (<1.0 cm)...

A search for scale in sea-level studies
C.E. Larsen, I. Clark
2006, Journal of Coastal Research (22) 788-800
Many researchers assume a proportional relationship among the atmospheric CO2 concentration, temperature, and sea level. Thus, the rate of sea-level rise should increase in concert with the documented exponential increase in CO2. Although sea surface temperature has increased in places over the past century and short-term sea level rose abruptly...

The role of fire refugia in the distribution of Pinus sabiniana (Pinaceae) in the southern Sierra Nevada
Dylan W. Schwilk, Jon E. Keeley
2006, Madroño (53) 364-372
Although widespread throughout the interior foothills of central and northern California, Pinus sabiniana Dougl. has a disjunct distribution in the southern Sierra Nevada, where it is abundant in the Kern River and Tule River watersheds, but is absent from the Kaweah River watershed between 36° and 37°N. This gap in the pine's...

Productivity of Black Oystercatchers: Effects of recreational disturbance in a National Park
J.A. Morse, A.N. Powell, M.D. Tetreau
2006, Condor (108) 623-633
National parks in Alaska are generally assumed to be high-quality, undisturbed wildlife habitats. However, these parks attract recreational users, whose presence may reduce the suitability of key habitats for nesting shorebirds. In Kenai Fjords National Park, Black Oystercatchers (Haematopus bachmani) often breed on gravel beaches that are also popular campsites....

Relations between climatic variability and hydrologic time series from four alluvial basins across the southwestern United States
R. T. Hanson, M. D. Dettinger, M.W. Newhouse
2006, Hydrogeology Journal (14) 1122-1146
Hydrologic time series of groundwater levels, streamflow, precipitation, and tree-ring indices from four alluvial basins in the southwestern United States were spectrally analyzed, and then frequency components were reconstructed to isolate variability due to climatic variations on four time scales. Reconstructed components (RCs), from each time series, were compared to...
Salinity effects on viability, metabolic activity and proliferation of three Perkinsus species
Peyre M. La, S. Casas, Peyre J. La
2006, Diseases of Aquatic Organisms (71) 59-74
Little is known regarding the range of conditions in which many Perkinsus species may proliferate, making it difficult to predict conditions favorable for their expansion, to identify conditions inducing mortality, or to identify instances of potential cross-infectivity among sympatric host species. In this study, the effects of salinity on viability,...

We report measurements and analysis of a boreal forest fire, integrating the effects of greenhouse gases, aerosols, black carbon deposition on snow and sea ice, and postfire changes in surface albedo. The net effect of all agents was to increase radiative forcing during the first year (34 ?? 31 Watts...

2006, Conference Paper, Proceedings of the 11th International High Level Radioactive Waste Management Conference, IHLRWM
Following a 5-month period of above-average precipitation during the winter of 2004-2005, water was observed seeping into the South Ramp section of the Exploratory Studies Facility of the proposed repository for high-level radioactive waste at Yucca Mountain, Nevada. Samples of the seepage were collected and analyzed for major ions, trace...

By 1973, radio telemetry was regarded as an important potential tool for studying the elusive, nocturnal, and semifossorial black-footed ferret (Mustela nigripes), but fears of using invasive techniques on this highly endangered mammal caused delays. We began radio collaring ferrets in 1981. Use of radio telemetry on ferrets proved to...

The black-footed ferret (Mustela nigripes) is a member of the weasel family (Mustelidae) and is closely related to the Siberian polecat (M. eversmannii) of Asian steppes and the European polecat (M. putorius). Compared to its relatives, the black-footed ferret is an extreme specialist, depending on the prairie dogs (Cynomys spp.)...
Frictional strength of cuttings and core from SAFOD drillhole phases 1 and 2
S. Tembe, D.A. Lockner, J.G. Solum, C.A. Morrow, T.-F. Wong, Diane E. Moore
2006, Geophysical Research Letters (33)
We investigated the frictional properties of drill cuttings and core obtained from 1.85-3.1 km true vertical depth in the SAFOD scientific borehole in central California. Triaxial frictional sliding experiments were conducted on samples from primary lithologic traits and significant shear zones, including the inferred active trace of the San Andreas...

The San Francisco Bay and delta system comprises the largest estuary along the Pacific Coast of the Americas and the largest remaining area for tidal-marsh vertebrates, yet tidal marshes have been dramatically altered since the middle of the 19th century. Although recent efforts to restore ecological functions are notable, numerous...

Fuel loads, fire regimes, and post-fire fuel dynamics in Florida Keys pine forests
J.P. Sah, M.S. Ross, J.R. Snyder, S. Koptur, H.C. Cooley
2006, International Journal of Wildland Fire (15) 463-478
In forests, the effects of different life forms on fire behavior may vary depending on their contributions to total fuel loads. We examined the distribution of fuel components before fire, their effects on fire behavior, and the effects of fire on subsequent fuel recovery in pine forests within the National...

2006, Geochimica et Cosmochimica Acta (70) 6118-6135
The martian orbital and landed surface missions, OMEGA on Mar Express and the two Mars Explorations Rovers, respectively, have yielded evidence pointing to the presence of magnesium sulfates on the martian surface. In situ identification of the hydration states of magnesium sulfates, as well as the hydration states of other...

2006, Conference Paper, North American Journal of Aquaculture
We describe the resident heterotrophic aerobic microflora of the salmonid posterior intestine before, during, and after the administration of rations with erythromycin in a hatchery raceway environment. We compare the profiles of medicated Chinook salmon Oncorhynchus tshawytscha with those of control fish that were not fed erythromycin. The combined counts...
Coseismic and postseismic slip of the 2004 Parkfield earthquake from space-geodetic data

2006, Bulletin of the Seismological Society of America (96)
We invert interferometric synthetic aperture radar (InSAR) data jointly with campaign and continuous global positioning system (GPS) data for slip in the coseismic and postseismic periods of the 2004 Parkfield earthquake. The InSAR dataset consists of eight interferograms from data collected by the Envisat and Radarsat satellites spanning the time...
Alternate corrections for estimating actual wetland evapotranspiration from potential evapotranspiration
W. Barclay Shoemaker, D. M. Sumner
2006, Wetlands (26) 528-543
Corrections can be used to estimate actual wetland evapotranspiration (AET) from potential evapotranspiration (PET) as a means to define the hydrology of wetland areas. Many alternate parameterizations for correction coefficients for three PET equations are presented, covering a wide range of possible data-availability scenarios. At nine sites in the wetland...
