Leg 202 synthesis: Southeast Pacific paleoceangraphy

Creator:: Tiedemann, Ralf and Mix, Alan C.
Abstract:: Ocean Drilling Program (ODP) Leg 202 has opened a new window into understanding late Paleogene and Neogene global environmental change by providing high-quality sediment sequences from a previously unsampled region, the eastern South Pacific. Eleven sites (1232– 1242) that record variations on timescales ranging from decades to tens of millions...

Comment on "Do geochemical estimates of sediment focusing pass the sediment test in the equatorial Pacific?" by M. Lyle et al.

Creator:: Francois, Roger, Frank, Martin, Rutgers van der Loeff, Michiel, Bacon, Michael P., Geibert, Walter, Kienast, Stephanie, Anderson, Robert F., Bradtmiller, Louisa, Chase, Zanna, Henderson, Gideon, Marcantonio, Franco, and Allen, Susan E.
Abstract:: Accurately estimating the vertical flux of material reaching the seafloor from the overlying surface waters is essential for the paleoceanographic reconstruction of a wide variety of oceanic processes. Two approaches are currently being used. One consists of estimating mass accumulation rates (MAR) between dated horizons as the product of linear...

Thorium-230 normalized particle flux and sediment focusing in the Panama Basin region during the last 30,000 years

Creator:: Kienast, S. S., Kienast, M., Mix, Alan C., Calvert, S. E., and Francois, R.
Abstract:: Application of the ²³⁰Th normalization method to estimate sediment burial fluxes in six cores from the eastern equatorial Pacific (EEP) reveals that bulk sediment and organic carbon fluxes display a coherent regional pattern during the Holocene that is consistent with modern oceanographic conditions, in contrast with estimates of bulk mass...

Production and export of biogenic silica in the Southern Ocean

Creator:: Sigmon, Daniel E.
Abstract:: Dissolved silicic acid (Si(OH)4) and biogenic silica (BSiO2) concentrations were measured on four different cruises in the Southern Ocean along 1700 W from late October 1997 to mid-March 1998. These data were used to construct a vertically integrated Si budget in the surface layer from 58° to 68° S. Throughout...

Phosphorus availability in biosolids-amended soils

Creator:: Choate, Jeff
Abstract:: Quantifying labile phosphorus (P) pools in biosolids is needed to manage biosolids for both agronomic and environmental purposes. Phosphorus indices originated in an effort to protect surface water quality from-non-point-agricultural P inputs. The objectives of this research were to: (1) evaluate soil test components of the western Oregon P index...

Regulation of inositol phospholipid hydrolysis by extended treatment with angiotensin II in human aortic smooth muscle cells

Creator:: Niibori, Yoshiko
Abstract:: Long-term stimuli of many systems leads to decreased cellular responsiveness, or desensitization. We characterized the desensitization of angiotensin II (Ang 11)-mediated inositol phospholipid (IP) hydrolysis in cultured human aortic smooth muscle cells (HASMC). Although it has been suggested that the desensitization induced by long-term Mg II exposure may result partially...

Maturity and stability evaluation of composted yard debris

Creator:: Brewer, Linda J.
Abstract:: Compost maturity is an important determinant of end use for composted municipal yard debris, and generally refers to the effect the compost has on plants. The rate of microbial respiration is an indicator of compost stability. The objectives of this research were to: i) determine whether continuous aeration resulted in...

Susceptibility of golden chinquapin (Chrysolepis chrysophylla) to Phytophthora cambivora

Creator:: Saavedra, Angel Luis
Abstract:: In early 2000, unusual mortality of a native North American tree, golden chinquapin, was reported by the USDA-Forest Service. Dying trees exhibited girdling cankers in the inner bark of the lower bole, branch flagging and defoliation. Isolations from necrotic tissues and soil associated with diseased or killed trees yielded Phytophthora...

Characterization of the molecular foundations and biochemistry of alkane and ether oxidation in a filamentous fungus, a Graphium species.

Creator:: Skinner, Kristin M.
Abstract:: Graphium sp., a eukaryotic alkanotroph, is able to oxidize small-molecular weight gaseous n-alkanes, diethyl ether and the branched ether, methyl tert butyl ether (MTBE). However, information regarding the biochemistry of fungal-mediated alkane and ether metabolism is limited, and questions regarding the identity of alkane oxidation catalysts and the genetic underpinnings...

Histological examination of Phytophthora ramorum in Notholithocarpus densiflorus bark tissues

Creator:: Botts, Molly M.
Abstract:: Colonization of N. densiflorus tissues by P. ramorum is not well understood. The pathogen is able to colonize nearly all tissues of this host but it is unclear how a tree is ultimately killed. Because this is such a destructive invasive pathogen, it is important to investigate its pathogenic strategy....
