Geochemical evidence for gas hydrate in sediment near the Chile Triple Juction

Creator:: Froelich, Philip N., Kvenvolden, Keith A., Torres, Marta E., Waseda, Amane, Didyk, Borys M., and Lorenson, Thomas D.
Abstract:: Coring at ODP Sites 859, 860, and 861 near the Chile Triple Junction failed to recover anticipated gas hydrate that was inferred to be present from two lines of geophysical evidence: pre-cruise observation of a weak to strong bottom simulating reflector (BSR) marking the predicted base of the gas-hydrate stability...

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...

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...

Chemical characteristics of ice residual nuclei in anvil cirrus clouds: evidence for homogeneous and heterogeneous ice formation

Creator:: Twohy, Cynthia and Poellot, M. R.
Abstract:: A counterflow virtual impactor was used to collect residual particles larger than about 0.1 μm diameter from anvil cirrus clouds generated over Florida in the southern United States. A wide variety of particle types were found. About one-third of the nuclei were salts, with varying amounts of crustal material, industrial...

Predicting global atmospheric ice nuclei distributions and their impacts on climate

Creator:: DeMott, P. J., Prenni, A. J., Liu, X., Kreidenweis, S. M., Petters, M. D., Twohy, Cynthia, Richardson, M. S., Eidhammer, T., and Rogers, D. C.
Abstract:: Knowledge of cloud and precipitation formation processes remains incomplete, yet global precipitation is predominantly produced by clouds containing the ice phase. Ice first forms in clouds warmer than −36 °C on particles termed ice nuclei. We combine observations from field studies over a 14-year period, from a variety of locations...

Temporal variability of Cd, Pb, and Pb, isotope deposition in central Greenland snow

Creator:: Sherrell, R. M., Boyle, E. A., Harris, N. R., and Falkner, Kelly
Abstract:: We present a decade-long (1981–1990) high-resolution (subseasonal) record of Pb and Cd concentrations and Pb isotopic composition in a series of 119 snow samples from a 6-m snow pit at Summit, Greenland. Both metals show order of magnitude seasonal variability, with maxima in spring of every year, coinciding with sulfate...

Ice Initiation by Aerosol Particles: Measured and Predicted Ice Nuclei Concentrations versus Measured Ice Crystal Concentrations in an Orographic Wave Cloud

Creator:: Eidhammer, T., DeMott, P. J., Prenni, A. J., Petters, M. D., Twohy, Cynthia, Rogers, D. C., Stith, J., Heymsfield, A., Wang, Z., Pratt, K. A., Prather, K. A., Murphy, S. M., Seinfeld, J. H., Subramanian, R., and Kreidenweis, S. M.
Abstract:: The initiation of ice in an isolated orographic wave cloud was compared with expectations based on ice nucleating aerosol concentrations and with predictions from new ice nucleation parameterizations applied in a cloud parcel model. Measurements of ice crystal number concentrations were found to be in good agreement both with measured...

Constraining recent lead pollution sources in the North Pacific using ice core stable lead isotopes

Creator:: Gross, B. H., Kreutz, K. J., Osterberg, E. C., McConnell, J. R., Handley, M., Wake, C. P., and Yalcin, K.
Abstract:: Trends and sources of lead (Pb) aerosol pollution in the North Pacific rim of North America from 1850 to 2001 are investigated using a high-resolution (subannual to annual) ice core record recovered from Eclipse Icefield (3017 masl; St. Elias Mountains, Canada). Beginning in the early 1940s, increasing Pb concentration at...

Aerosol particles collected on aircraft flights over the northwestern Pacific region during the ACE-Asia campaign: Composition and major sources of the organic compounds

Creator:: Simoneit, Bernd R. T., Kobayashi, Minoru, Mochida, Michihiro, Kawamura, Kimitaka, and Huebert, Barry J.
Abstract:: Atmospheric particulate matter, collected over the polluted east Asia/Pacific region in spring 2001 during research flights with the National Center for Atmospheric Research (NCAR) C-130 aircraft, was analyzed for different types of organic compounds using capillary gas chromatography–mass spectrometry. More than 70 organic species were detected in the aerosols and...
