Integrating precipitation, grazing, past effects and interactions in long-term vegetation change

Creator:: Morris, Christo, Badik, Kevin J., Morris, Lesley R., and Weltz, Mark A.
Abstract:: Determining the causes of vegetation change in arid and semi-arid environments can be difficult and may involve multiple factors, including disturbance, inter-annual climatic variation, soils, effects from years past and interactions between these factors. Theoretical models describing vegetation change in these systems have generally focused on a single aspect as...

Data report : trace element, Sr isotope, and Ge/SI composition of fluid and sediments in ridge-flank low-temperature hydrothermal environments

Creator:: Hulme, Samuel M., Wheat, C. Geoffrey, Coggon, Rosalind M., and McManus, James
Abstract:: The data presented in this report demonstrate significant improvements in the ability to constrain trace element and Sr isotopic concentrations in sediments overlying ridge-flank hydrothermal systems. Improved sampling methods orchestrated by the Integrated Ocean Drilling Program (i.e., advanced piston coring and anoxic sample processing) enabled the collection of reactive pore...

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...

Benthic foraminiferal stable isotope stratigraphy of Site 846 : 0-1.8 Ma

Creator:: Mix, Alan C., Le, J., and Shackleton, N. J.
Abstract:: A stable-isotope stratigraphy at Site 846 (tropical Pacific, 3°06'S, 90°49'W, 3307 m water depth), based on the benthic foraminifers Cibicides wuellerstorfi and Uvigerina peregrina, yields a high-resolution record of deep-sea δ¹⁸O and δ¹³C over the past 1.8 Ma, with an average sampling interval of 3 k.y. Variance in the δ¹⁸O...

Abstract:: A publication containing advice on a wide range of gardening topics, including composting, container gardens, fall/winter gardens, fertilizing, insect pests, plant diseases, planting guidelines, raised beds, site selection, slugs, soil improvement, tilling, warm-season crops, watering, and weeds. Includes regional tips for various parts of Oregon.

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...

A summary of ODP leg 141 hydrogeologic, geochemical and thermal results

Creator:: Brown, K. M., Bangs, Nathan Lawrence Bailey, Froelich, Peter N., Zheng, Y., Didyk, Borys M., Prior, D., Rochford, E. L., Torres, Marta E., Kurnosov, V. B., Lindsley - Griffin, N., Osozawa, S., and Waseda, A.
Abstract:: The subduction of the oceanic spreading center at the Chile Triple Junction is marked by a substantial thermal perturbation and marked changes in the hydrogeologic and aqueous geochemical regimes in the overthrust plate. Ridge subduction substantially changes the fluid chemistry in the wedge through variably hydrating the oceanic basement, accretionary...

Geological and geochemical contraints on the isotopic composition of interstitial waters from the Hydrate Ridge region, Cascadia Continental margin

Creator:: Tomaru, A. M., Matsumoto, R., Torres, Marta E., and Borowski, Walter S.
Abstract:: The isotopic compositions of interstitial waters collected from Hydrate Ridge during Ocean Drilling Program Leg 204 were measured to evaluate the fluid evolution of this accretionary prism. At shallow depths, the dissolved Cl- concentrations and δD and δ¹⁸O values of the interstitial water reflect changes in the salinity and the...

Color Reflectance Spectroscopy : a tool for rapid characterization of deep-sea sediments

Creator:: Mix, Alan C., Rugh, W., Pisias, Nicklas G., Veirs, S., and Leg 138 Scientific Party
Abstract:: During ODP Leg 138, we tested a prototype instrument, developed at Oregon State University, for measuring light reflectance in 511 channels of the visible and near-infrared bands. The technique of reflectance spectroscopy has been used for some time in chemistry and mineralogy (e.g., Hunt, 1977; Gaffey, 1986) and has found...
