Short-lived and discontinuous intraplate volcanism in the South Pacific: Hot spots or extensional volcanism?

Creator:: Koppers, Anthony A. P., Staudigel, Hubert, Pringle, Malcolm S., and Wijbrans, Jan R.
Abstract:: South Pacific intraplate volcanoes have been active since the Early Cretaceous. Their HIMU-EMI-EMII mantle sources can be traced back into the West Pacific Seamount Province (WPSP) using plate tectonic reconstructions, implying that these distinctive components are enduring features within the Earth's mantle for, at least, the last 120 Myr. These...

A new mechanism for Dansgaard-Oeschger cycles

Creator:: Petersen, S. V., Schrag, D. P., and Clark, P. U.
Abstract:: We present a new hypothesis to explain the millennial-scale temperature variability recorded in ice cores known as Dansgaard-Oeschger (DO) cycles. We propose that an ice shelf acted in concert with sea ice to set the slow and fast timescales of the DO cycle, respectively. The abrupt warming at the onset...

Analytical solution and simplified analysis of coupled parent-daughter steady-state transport with multirate mass transfer

Creator:: Haggerty, Roy
Abstract:: In this technical note, a steady-state analytical solution of concentrations of a parent solute reacting to a daughter solute, both of which are undergoing transport and multirate mass transfer, is presented. Although the governing equations are complicated, the resulting solution can be expressed in simple terms. A function of the...

A-posteriori analysis of surface energy budget closure to determine missed energy pathways

Creator:: Higgins, Chad W.
Abstract:: The residual of the surface energy budget is represented as the linearized sum of energy losses due to storage, advection and flux underestimation. Individual contributions to the residual can be quantified through constrained multiple linear regression which identifies the site specific processes that are responsible for the lack of energy...

Storm-induced upwelling of high pCO2 waters onto the continental shelf of the western Arctic Ocean and implications for carbonate mineral saturation states

Creator:: Mathis, Jeremy T., Pickart, Robert S., Byrne, Robert H., McNeil, Craig L., Moore, G. W. K., Juranek, Laurie W., Liu, Xuewu, Ma, Jian, Easley, Regina A., Elliot, Matthew M., Cross, Jessica N., Reisdorph, Stacey C., Bahr, Frank, Morison, Jamie, and Lichendorf, Trina
Abstract:: The carbon system of the western Arctic Ocean is undergoing a rapid transition as sea ice extent and thickness decline. These processes are dynamically forcing the region, with unknown consequences for CO2 fluxes and carbonate mineral saturation states, particularly in the coastal regions where sensitive ecosystems are already under threat...

The paradox of cooling streams in a warming world:Regional climate trends do not parallel variable local trends in stream temperature in the Pacific continental United States

Creator:: Arismendi, Ivan, Johnson, Sherri L., Dunham, Jason B., Haggerty, Roy, and Hockman-Wert, David
Abstract:: Temperature is a fundamentally important driver of ecosystem processes in streams. Recent warming of terrestrial climates around the globe has motivated concern about consequent increases in stream temperature. More specifically, observed trends of increasing air temperature and declining stream flow are widely believed to result in corresponding increases in stream...

Global net community production and the putative net heterotrophy of the oligotrophic oceans

Creator:: Westberry, Toby K., Williams, Peter J. le B., and Behrenfeld, Michael J.
Abstract:: Reconciling rates of organic carbon export from the euphotic zone with the consumption of organic material in the dark ocean remains one of the major quantitative uncertainties of the ocean carbon cycle. Euphotic zone net community production (NCP) provides one broad constraint on export flux and potential carbon drawdown. However,...

Fuel moisture influences on fire-altered carbon in masticated fuels: An experimental study

Creator:: Brewer, Nolan W., Smith, Alistair M. S., Hatten, Jeffery A., Higuera, Philip E., Hudak, Andrew T., Ottmar, Roger D., and Tinkham, Wade T.
Abstract:: Biomass burning is a significant contributor to atmospheric carbon emissions but may also provide an avenue in which fire-affected ecosystems can accumulate carbon over time, through the generation of highly resistant fire-altered carbon. Identifying how fuel moisture, and subsequent changes in the fire behavior, relates to the production of fire-altered...

Nonlinear ⁴⁰Ar/³⁹Ar age systematics along the Gilbert Ridge and Tokelau Seamount Trail and the timing of the Hawaii-Emperor Bend

Creator:: Koppers. Anthony A. P., Staudigel, Hubert, Morgan, Jason Phipps, and Dunca, Robert A.
Abstract:: Over the last three decades the first-order correlation in morphology and orientation of seamount trails has been called upon to support the concept of a ‘‘fixed’’ Pacific hot spot frame of reference and to explain the Hawaii-Emperor bend (HEB) by a dramatic change in Pacific plate motion. In this paper,...

Implications of a nonlinear ⁴⁰Ar/³⁹Ar age progression along the Louisville seamount trail for models of fixed and moving hot spots

Creator:: Koppers, Anthony A. P., Duncan, Robert A., and Steinberger, Bernhard
Abstract:: The Louisville seamount trail has been recognized as one of the key examples of hot spot volcanism, comparable to the classic volcanic Hawaiian-Emperor lineaments. The published total fusion ⁴⁰Ar/³⁹Ar data of Watts et al. [1988] showed an astonishing linear age progression, firmly establishing Louisville as a fixed hot spot in...
