Organic matter and carbon isotope composition of carbonate nodules and associated sediments from middle valley, leg 139

Creator:: Boni, M., Simoneit, Bernd R. T., Früh-Green, G. L., Lief, R. N., and McKenzie, J. A.
Abstract:: Carbonate nodules and associated sediments from Ocean Drilling Program Leg 139 sites of the Middle Valley, Juan de Fuca Ridge, were studied using a combination of inorganic and organic geochemical techniques. The mineralogy and stable isotopic compositions defined three types of nodules, reflecting the conditions of carbonate precipitation. Nodule ingrowth...

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...

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...

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...

Cupric Oxide (CuO) Oxidation Detects Pyrogenic Carbon in Burnt Organic Matter and Soils

Creator:: Hatten, Jeff and Goñi, Miguel
Abstract:: Wildfire greatly impacts the composition and quantity of organic carbon stocks within watersheds. Most methods used to measure the contributions of fire altered organic carbon–i.e. pyrogenic organic carbon (Py-OC) in natural samples are designed to quantify specific fractions such as black carbon or polyaromatic hydrocarbons. In contrast, the CuO oxidation...

Trends in the suspended-sediment yields of coastal rivers of northern California, 1955–2010

Creator:: Warrick, J. A., Madej, M. A., Goñi, M. A., and Wheatcroft, R. A.
Abstract:: Time-depe ndencies of suspended-sediment discharge from six coastal watersheds of northern Califor nia – Smith River, Klamath River, Trinity River, Redwood Creek, Mad River, and Eel River –were evaluated using monitoring data from 1955 to 2010. Suspended-sediment concentrations revealed ti me-dependent hysteresis and multi-year trends. The multi-year trends had two...

Intertidal zone particulate organic carbon redistribution by low-tide rainfall

Creator:: Chen, Si, Torres, Raymond, and Goñi, Miguel A.
Abstract:: We present field data and data from the literature to highlight the effects of low-tide rainfall on particulate organic carbon (POC) redistribution in intertidal landscapes. The POC exchanges reported from disparate but related studies were standardized to a storm-induced exchange rate (gPOC m⁻² mmRain⁻¹) and compared. Results show that these...
