Uncertainties in, and interpretation of, carbon flux estimates using the eddy covariance technique

Creator:: Loescher, H. W., Law, B. E., Mahrt, Larry, Hollinger, D. Y., Campbell, J., and Wofsy, S. C.
Abstract:: Whole ecosystem carbon dioxide (CO₂) exchange estimated with the eddy covariance (EC) technique has been central to studies on the responses of terrestrial ecosystems to disturbance and intra‐annual and interannual variations in climate, but challenges exist in understanding and reducing the uncertainty in estimates of net ecosystem exchange (NEE) of...

Crustal wedging triggering recent deformation in the Andean thrust front between 31°S and 33°S: Sierras Pampeanas-Precordillera interaction

Creator:: Verges, J., Ramos, V. A., Meigs, A., Cristallini, E., Bettini, F. H., and Cortes, J. M.
Abstract:: We document a new model of crustal structure of the Andean front in Argentina where numerous historic earthquakes destroyed the cities of Mendoza in 1861 (M[subscript s] = ~7) and San Juan in 1944 (M[subscript w] = 7.0). The Cerro Salinas anticline is formed above the west directed Cerro Salinas...

p-type conductivity in wide-band-gap BaCuQF (Q=S,Se)

Creator:: Yanagi, Hiroshi, Tate, Janet, Park, Sangmoon, Park, Cheol-Hee, and Keszler, Douglas A.
Abstract:: BaCuQF (Q=S,Se) materials, candidate transparent p-type conductors, were prepared by solid-state reaction, and their bulk electrical and optical properties were evaluated. The room-temperature Seebeck coefficient and electrical conductivity of undoped BaCuQF pellets were +56 μV/K and 0.088 S/cm, respectively, for the sulfide fluoride, and +32 μV/K and 0.061 S/cm, respectively,...

Spatial and temporal distribution of a C-like asthenoshpheric component in the Rano Rahi Seamount Field, East Pacific Rise, 15°-19°S

Creator:: Hall, L. S., Mahoney, J. J., Sinton, J. M., and Duncan, Robert A.
Abstract:: Lavas of the Rano Rahi seamount field define a Nd-Pb-Sr isotopic array that connects, and substantially overlaps, the arrays of the nearby East Pacific Rise axis and 5.6–28 Ma lavas of the Pukapuka ridge system, situated between the seamount field and French Polynesia. Dating of Rano Rahi samples by ⁴⁰Ar-³⁹Ar...

Composition and major sources of organic compounds of aerosol particulate matter sampled during the ACE-Asia campaign

Creator:: Simoneit, Bernd R. T., Kobayashi, Minoru, Mochida, Michihiro, Kawamura, Kimitaka, Lee, Meehye, Lim, Ho-Jin, Turpin, Barbara J., and Komazaki, Yuichi
Abstract:: The organic compound tracers of atmospheric particulate matter, as well as organic carbon (OC) and elemental carbon (EC), have been characterized for samples acquired during the Asian Pacific Regional Aerosol Characterization Experiment (ACE-Asia) from Gosan, Jeju Island, Korea, from Sapporo, Japan, and from Chichi-jima Island in the western North Pacific,...

Wildlife Encounters by Lewis and Clark: A Spatial Analysis of Interactions between Native Americans and Wildlife

Creator:: Laliberte, Andrea S. and Ripple, William J.
Abstract:: The Lewis and Clark journals contain some of the earliest and most detailed written descriptions of a large part of the United States before Euro-American settlement.We used the journal entries to assess the influence of humans on wildlife distribution and abundance. Areas with denser human population, such as the Columbia...

Climate change in India inferred from geothermal observations

Creator:: Roy, Sukanta, Harris, Robert N., Rao, R. U. M., and Chapman, David S.
Abstract:: Temporal variations in surface ground temperature impart a signal to the subsurface thermal regime that is captured in borehole temperature-depth profiles. Seventy temperature-depth profiles in India, located between 12° and 28°N, are analyzed to infer past changes in ground temperature. These profiles exhibit predominantly positive anomalous temperatures relative to the...

Water vapor transport in the vicinity of imbibing saline plumes: Homogeneous and layered unsaturated porous media

Creator:: Weisbrod, Noam, Niemet, Michael R., McGinnis, Thomas, and Selker, John S.
Abstract:: Water vapor transport in the vicinity of imbibing saline solutions was investigated in two-dimensional (2-D) chambers using a light transmission technique. Concentrated NaNO3 solutions (brines) were applied as point sources to the surface of homogenous packs of prewetted silica sand for four different sand grades. The same solutions were applied...

Methods for colloid transport visualization in pore networks

Creator:: Ochiai, Naoyuki, Kraft, Erika L., and Selker, John S.
Abstract:: Prediction of colloid transport in the subsurface is relevant to researchers in a variety of fields such as contaminant transport, wastewater treatment, and bioremediation. Investigations have traditionally relied on column studies whereby mechanistic inferences must be drawn on the basis of colloid behavior at the outlet. Over the past decade,...

Short-lived and discontinuous intraplate volcanism in the South Pacific: Hot spots or extensional volcanism?

Creator:: Koppers, Anthony A. P., Staudigel, Hubert, Pringle, Malcolm S., and Wijbrans, Jan R.
Abstract:: South Pacific intraplate volcanoes have been active since the Early Cretaceous. Their HIMU-EMI-EMII mantle sources can be traced back into the West Pacific Seamount Province (WPSP) using plate tectonic reconstructions, implying that these distinctive components are enduring features within the Earth's mantle for, at least, the last 120 Myr. These...
