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...

Comparison of Phellinus weirdi root rot damage in a 60-year-old Douglas-fir (Pseudotsuga menziesii) stand with the damage in the preceding old-growth stand

Creator:: Tkacz, Borys M.
Abstract:: Laminated root rot of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) caused by the fungus Phellinus weirii (Murr.)Gilbertson was studied in two successive stands in the Oregon Coast Range. Damage due to the disease in a 60-year-old second-growth stand was compared with incidence in the preceding 300-year-old stand on the same site....

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...

Pathogenicity of Phytophthora species from Oregon waterways

Creator:: Navarro, Sarah M.
Abstract:: Described as one of the most destructive pathogens of agricultural crops and forest trees, Phytophthora is a genus of microorganisms containing over 100 known species. Phytophthora alni has caused collar and root disease in alders throughout Europe and a form of the species has recently been isolated in North America....

Moving Towards Academic Success and Life Long Learning

Creator:: Becker, Derek R.
Abstract:: Early learning skills, such as executive function (EF), are a key component of healthy development and predict long-term academic success. Yet many children are entering kindergarten without the necessary skills (including EF) that are needed to set them on a successful learning trajectory. Early prekindergarten classrooms that encourage a high...

Pathogenesis and intertree transmission of Verticicladiella wageneri in Douglas-fir (Pseudotsuga menziesii)

Creator:: Hessburg, Paul F.
Abstract:: Verticicladiella wageneri Kendr. is a vascular wilt pathogen of Douglas-fir in the Pacific Northwest, The disease is characterized by black staining of colonized sapwood; crown symptoms are those typical of a wilting syndrome. Histopathological studies revealed that the pathogen is limited to the xylem but causes vascular dysfunction in both...

Pathological and ecological aspects of decline and mortality of Chamaecyparis nootkatensis in southeast Alaska

Creator:: Hennon, Paul Edward
Abstract:: Alaska-cedar (Chamaecvparis nootkatensIs (D. Don) Spach) is a valuable tree that is suffering from a serious decline and mortality of unknown cause throughout southeast Alaska. Epidemiological and pathological studies were initiated to determine if a pathogen is the primary cause of this problem. By examining old aerial photographs and by...

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...
