Organic matter compositions and loadings in soils and sediments along the Fly River, Papua New Guinea

Creator:: Goni, Miguel A., Moore, Eric, Kurtz, Andrew, Portier, Evan, Alleau, Yvan, and Merrell, David
Abstract:: The compositions and loadings of organic matter in soils and sediments from a diverse range of environments along the Fly River system were determined to investigate carbon transport and sequestration in this region. Soil horizons from highland sites representative of upland sources have organic carbon contents (%OC) that range from...

Mineral changes in cement-sandstone matrices induced by biocementation

Creator:: Verba, C., Thurber, A. R., Alleau, Y., Koley, D., Colwell, F., and Torres, M. E.
Abstract:: Prevention of wellbore CO₂ leakage is a critical component of any successful carbon capture, utilization, and storage program. Sporosarcina pasteurii is a bacterium that has demonstrated the potential ability to seal a compromised wellbore through the enzymatic precipitation of CaCO₃. Here we investigate the growth of S. pasteurii in a...

Real-time monitoring of calcification process by Sporosarcina pasteurii biofilm

Creator:: Harris, Dustin, Ummadi, Jyothir Ganesh, Thurber, Andrew R., Allau, Yvan, Verba, Circe, Colwell, Frederick, Torres, Marta E., and Koley, Dipankar
Abstract:: Sporosarcina pasteurii is known to produce calcite or biocement in the presence of urea and Ca²⁺. Herein, we report the use of novel ultramicrosensors such as pH, Ca²⁺, and redox sensors, along with a scanning electrochemical microscope (SECM), to monitor a real-time, bacteria-mediated urea hydrolysis process and subsequent changes in...

Piscivorous colonial waterbirds in the Columbia River estuary : demography, dietary contaminants, and management

Creator:: Suzuki, Yasuko
Abstract:: Caspian terns (Hydroprogne caspia) and double-crested cormorants (Phalacrocorax auritus) nest in large colonies on East Sand Island in the Columbia River estuary, the largest known colonies for the two species in the world. Both species of piscivorous colonial waterbirds have been identified as predators with a significant impact on the...

Particle size characterization of historic sediment deposition from a closed estuarine lagoon, Central California

Creator:: Watson, Elizabeth Burke, Pasternack, Gregory B., Gray, Andrew B., Goñi, Miguel, and Woolfolk, Andrea M.
Abstract:: Recent studies of estuarine sediment deposits have focused on grain size spectra as a tool to better understand depositional processes, in particular those associated with tidal inlet and basin dynamics. The key to accurate interpretation of lithostratigraphic sequences is establishing clear connections between morphodynamic changes and the resulting shifts in...

The effects of wildfire on the sediment yield of a coastal California watershed

Creator:: Warrick, J. A., Hatten, J. A., Pasternack, G. B., Gray, A. B., Goni, M. A., and Wheatcroft, R. A.
Abstract:: The occurrence of two wildfires separated by 31 yr in the chaparral-dominated Arroyo Seco watershed (293 km²) of California provides a unique opportunity to evaluate the effects of wildfire on suspended-sediment yield. Here, we compile discharge and suspended-sediment sampling data from before and after the fires and show that the...

Analysis of particulate organic matter distribution along surface waters of the California Current

Creator:: Welch, Kylie
Abstract:: Water samples along the Washington, Oregon and California coastline were collected using high resolution sampling and analyzed to determine particulate organic carbon and nitrogen concentrations. Over 28 days during August 2011, nearly 1500 samples were collected aboard the R/V Wecoma (W1108C) using a semi-automated filtration system. Additional subsurface samples were...

Benthic oxygen consumption rates during hypoxic conditions on the Oregon continental shelf: Evaluation of the eddy correlation method

Creator:: Reimers, Clare E., Özkan-Haller, H. Tuba, Berg, Peter, Devol, Allan, McCann-Grosvenor, Kristina, and Sanders, Rhea D.
Abstract:: Three stations, at ∼80 m water depth on the Oregon shelf between 44.7°N and 43.9 N, were studied under hypoxic conditions in late spring and summer of 2009 to determine benthic oxygen consumption rates. Oxygen fluxes were derived from eddy correlation (EC) measurements made from an autonomous lander deployed for...

Lime application effects on soil aggregate properties: Use of the mean weight diameter and synchrotron-based X-ray mu CT techniques

Creator:: Ferreira, Talita R., Pires, Luiz F., Wildenschild, Dorthe, Brinatti, Andre M., Borges, Jaqueline A. R., Auler, Andre C., and dos Reis, Aline M. H.
Abstract:: The hierarchical organization of aggregates in soil is responsible for the presence of inter and intra-aggregate pores. This research aimed to investigate effects of soil surface liming, considering lime rates of 0, 10 and 15 t ha(-1), on the intra-aggregate porous system of soil aggregates with equivalent diameters of 2-4...

Benthic oxygen consumption rates during hypoxic conditions on the Oregon continental shelf: Evaluation of the eddy correlation method

Creator:: Reimers, Clare E., Özkan-Haller, H. Tuba, Berg, Peter, Devol, Allan, McCann-Grosvenor, Kristina, and Sanders, Rhea D.
Abstract:: Three stations, at similar to ~80 m water depth on the Oregon shelf between 44.7 degrees N and 43.9 N, were studied under hypoxic conditions in late spring and summer of 2009 to determine benthic oxygen consumption rates. Oxygen fluxes were derived from eddy correlation (EC) measurements made from an...
