Online preconcentration ICP-MS analysis of rare earth elements in seawater

Creator:: Hathorne, Ed C., Haley, Brian, Stichel, Torben, Grasse, Patricia, Zieringer, Moritz, and Frank, Martin
Abstract:: The rare earth elements (REEs) with their systematically varying properties are powerful tracers of continental inputs, particle scavenging intensity and the oxidation state of seawater. However, their generally low (similar to pmol/kg) concentrations in seawater and fractionation potential during chemical treatment makes them difficult to measure. Here we report a...

Sources and input mechanisms of hafnium and neodymium in surface waters of the Atlantic sector of the Southern Ocean

Creator:: Stichel, Torben, Frank, Martin, Rickli, Jorg, Hathorne, Ed C., Haley, Brian A., Jeandel, Catherine, and Pradoux, Catherine
Abstract:: Radiogenic isotopes of hafnium (Hf) and neodymium (Nd) are powerful tracers for water mass transport and trace metal cycling in the present and past oceans. However, due to the scarcity of available data the processes governing their distribution are not well understood. Here we present the first combined dissolved Hf...

High-resolution infrared studies of perdeutero-spiropentane, C₅D₈

Creator:: Erickson, B. A., Ju, X., Nibler, J. W., Beaudry, C. M., and Blake, T. A.
Abstract:: Perdeutero-spiropentane (C₅D₈) has been synthesized, and infrared and Raman spectra are reported for the first time. Wavenumber assignments are made for most of the fundamental vibrational states. Gas phase infrared spectra were recorded at a resolution (0.002 cm⁻¹) sufficient to resolve individual rovibrational lines and show evidence of strong Coriolis...

Inhibitory Effects of C₂ to C₁₀ 1-Alkynes on Ammonia Oxidation in Two Nitrososphaera Species

Creator:: Taylor, A. E., Taylor, K., Tennigkeit, B., Palatinszky, M., Stieglmeier, M., Myrold, D. D., Schleper, C., Wagner, M., and Bottomley, P. J.
Abstract:: A previous study showed that ammonia oxidation by the Thaumarchaeota Nitrosopumilus maritimus (group 1.1a) was resistant to concentrations of the C₈ 1-alkyne, octyne, which completely inhibits activity by ammonia-oxidizing bacteria. In this study, the inhibitory effects of octyne and other C₂ to C₁₀ 1-alkynes were evaluated on the nitrite production...

¹⁴C and ¹³C characteristics of higher plant biomarkers in Washington margin surface sediments

Creator:: Feng, Xiaojuan, Benitez-Nelson, Bryan C., Montlucon, Daniel B., Prahl, Fredrick G., McNichol, Ann P., Xu, Li, Repeta, Daniel J., and Eglinton, Timothy I.
Abstract:: Plant wax lipids and lignin phenols are the two most common classes of molecular markers that are used to trace vascular plant-derived OM in the marine environment. However, their ¹³C and ¹⁴C compositions have not been directly compared, which can be used to constrain the flux and attenuation of terrestrial...

Interlaboratory comparison study of calibration standards for foraminiferal Mg/Ca thermometry

Creator:: Greaves, M., Caillon, N., Rebaubier, H., Bartoli, G., Boharty, S., Cacho, I., Clarke, L., Cooper, M., Daunt, C., Delaney, M., deMenocal, P., Dutton, A., Eggins, S., Elderfield, H., Garbe-Schoenberg, D., Goddard, E., Green, D., Groeneveld, J., Hastings, D., Hathorne, E., Kimoto, K., Klinkhammer, Gary P., Labeyrie, L., Lea, D.

Abstract:: An interlaboratory study of Mg/Ca and Sr/Ca ratios in three commercially available carbonate reference materials (BAM RS3, CMSI 1767, and ECRM 752-1) was performed with the participation of 25 laboratories that determine foraminiferal Mg/Ca ratios worldwide. These reference materials containing Mg/Ca in the range of foraminiferal calcite (0.8 mmol/mol to...

Characterizing perpendicular-to-grain compression (C⊥) behavior in wood construction

Creator:: Basta, Craig Thomas, Gupta, Rakesh, Leichti, Robert J., and Sinha, Arijit
Abstract:: Current compression perpendicular-to-grain (C⊥) design values for wood members are based on mean stress obtained from ASTM D143 specimen. The standard ASTM test with metal on wood bearing has limited applicability in modern construction assemblies with C⊥ loading scenarios. Previous work has shown that end-bearing conditions and wood-on-wood C⊥ bearing...

Generalized Inversion of Tropical Atmosphere–Ocean Data and a Coupled Model of the Tropical Pacific

Creator:: Bennett, Andrew F., Chua, Boon S., Harrison, D. Ed, and McPhaden, Michael J.
Abstract:: It is hypothesized that the circulation of the tropical Pacific Ocean and atmosphere satisfies the equations of a simple coupled model to within errors having specified covariances, and that the Tropical Atmosphere–Ocean array (TAO) measures the circulation to within errors also having specified covariances. This hypothesis is tested by finding...

Generalized Inversion of Tropical Atmosphere–Ocean (TAO) Data and a Coupled Model of the Tropical Pacific. Part II: The 1995–96 La Niña and 1997–98 El Niño

Creator:: Bennett, Andrew F., Chua, Boon S., Harrison, D. Ed, and McPhaden, Michael J.
Abstract:: The investigation of the consequences of trying to blend tropical Pacific observations from the Tropical Atmosphere–Ocean (TAO) array into the dynamical framework of an intermediate coupled ocean–atmosphere model is continued. In a previous study it was found that the model dynamics, the prior estimates of uncertainty in the observations, and...
