Fingered Flow in Two Dimensions 2. Predicting Finger Moisture Profile

Creator:: Selker, J., Parlange, J.-Y., and Steenhuis, T.
Abstract:: An exact integral solution for the moisture profile in growing fingers in sandy soil is derived from Richards' equation. The solution provides moisture content along a finger as a function of position and time and provides applicable results, including the calculation of the asymptotic matric potential of a growing finger...

North-south variability in the history of deformation and fluid venting across Hydrate Ridge, Cascadia margin

Creator:: Johnson, Joel E., Goldfinger, Chris, Tréhu, Anne M., Bangs, Nathan Lawrence Bailey, Torres, Marta E., and Chevallier, Johanna
Abstract:: Hydrate Ridge is an accretionary thrust ridge located on the lower slope of the central Cascadia convergent margin. Structural mapping based on two-dimensional and three-dimensional multichannel seismic reflection profiles and gridded bathymetry coupled with deep-towed sidescan sonar data and Ocean Drilling Program (ODP) biostratigraphy suggests that seafloor fluid venting patterns...

Lipid/bitumen maturation by hydrothermal activity in sediments of Middle Valley, leg 139

Creator:: Simoneit, Bernd R. T.
Abstract:: The accelerated diagenesis, maturation, and catagenesis of organic matter to hydrothermal petroleum was studied in sediments from Ocean Drilling Program Leg 139 in Middle Valley, northern Juan de Fuca Ridge. Sediments at Sites 855 and 856 have experienced high heat flow resulting in accelerated diagenesis of the immature organic matter...

Ice Sheet Sources of Sea Level Rise and Freshwater Discharge During the Last Deglaciation

Creator:: Carlson, Anders E. and Clark, Peter U.
Abstract:: We review and synthesize the geologic record that constrains the sources of sea level rise and freshwater discharge to the global oceans associated with retreat of ice sheets during the last deglaciation. The Last Glacial Maximum (~26–19 ka) was terminated by a rapid 5–10 m sea level rise at 19.0–19.5...

Spatial and temporal variability of late Neogene Equatorial Pacific carbonate : ODP Leg 138

Creator:: Hagelberg, T. K., Pisias, Nicklas G., Mayer, L. A., Shackleton, N. J., and Mix, Alan C.
Abstract:: High resolution, continuous records of GRAPE wet bulk density (a carbonate proxy) from Ocean Drilling Program Leg 138 provide one the opportunity for a detailed study of eastern equatorial Pacific Ocean carbonate sedimentation during the last 6 m.y. The transect of sites drilled spans both latitude and longitude in the...

Sediment depths determined by comparison of grape and logging denisty data during Leg 138

Creator:: Mix, Alan C., Harris, Sara E., Hagelberg, T. K., Pisias, Nicklas G., and Shackleton, N. J.
Abstract:: Establishing true depths of recovered sediments is critical to determining sedimentation rates for high-resolution paleoclimatic studies. We have corrected the composite depth scale, which accounts for the entire continuous sedimentary sequence, so that sediment depths are consistent with logging depths, or "true" depths. We accomplished this by taking advantage of...

Combinatorial resveratrol and quercetin polymeric micelles mitigate doxorubicin induced cardiotoxicity in vitro and in vivo

Creator:: Cote, Brianna, Carlson, Lisa Janssen, Rao, Deepa A., and Alani, Adam W. G.
Abstract:: Doxorubicin hydrochloride (ADR) is an anthracycline antibiotic used to treat various cancers. However, due to its extensive cardiotoxic side effects a lifetime cumulative dose limit of 450–550 mg/m2 exists. The postulated mechanism of the cardiotoxicity is generation of reactive oxygen and nitrogen species. Natural products like resveratrol (RES), and quercetin...

Dissolved organic carbon in interstitial waters from sediments of Middle Valley, leg 139

Creator:: Ran, Baiyun and Simoneit, Bernd R. T.
Abstract:: High-temperature combustion oxidation measurements of nonvolatile dissolved organic carbon (DOC) have been determined for pore waters from sediments of Middle Valley, Ocean Drilling Program Leg 139, as well as for overlying and near-bottom seawater. The DOC values in the interstitial waters are generally greater than those in the overlying water...

Alkenones in sediments of Middle Valley, Leg 139 : application as thermal sensors

Creator:: Simoneit, Bernd R. T., Prahl, Fredrick, Leif, R. N., and Mao, S. Z.
Abstract:: The shallow sections of most holes drilled during Ocean Drilling Program Leg 139 contain alkenones derived from prymnesiophyte algae. The alkenones indicate a paleotemperature of the photic zone in the upper ocean during primary carbon fixation of 7°-15°C, with an average of 10.7°C. Based on laboratory hydrous pyrolyses these alkenones...

Thermogenic and bacterial hydrocarbon gases (free and sorbed) in Middle Valley, Juan De Fuca Ridge, Leg 139

Creator:: Whiticar, Michael J., Faber, Eckhard, Whelan, Jean K., and Simoneit, Bernd R. T.
Abstract:: The sorbed gases at all four Ocean Drilling Program Leg 139 sites (855, 856, 857, and 858) showed the unmistakable presence of thermogenic hydrocarbons. No indication of abiogenic gas was found. The evidence for the thermogenic hydrocarbons includes elevated contents of higher hydrocarbons (i.e., C₁/[C₂ + C₃] ca. 2-20), δ¹³CCH₄...
