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,...

Thermal effects of hydrothermal circulation and seamount subduction: Temperatures in the Nankai Trough Seismogenic Zone Experiment transect, Japan

Creator:: Spinelli, G. A. and Harris, R. N.
Abstract:: We examine the thermal effects of seamount subduction. Seamount subduction may cause transient changes in oceanic crust hydrogeology and plate boundary fault position. Prior to subduction, seamounts provide high-permeability pathways between the basaltic crustal aquifer and overlying ocean that can focus fluid flow and efficiently cool the oceanic crust. As...

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...

Thermal regime of the Costa Rican convergent margin: 2. Thermal models of the shallow Middle America subduction zone offshore Costa Rica

Creator:: Harris, Robert N., Spinelli, Glenn, and Ranero, César R.
Abstract:: At the Costa Rica margin along the Middle America Trench along‐strike variations in heat flow are well mapped. These variations can be understood in terms of either ventilated fluid flow, where exposed basement allows fluids to freely advect heat between the crustal aquifer and ocean, or insulated fluid flow where...

A synthesis of heat flow determinations and thermal modeling along the Nankai Trough, Japan

Creator:: Harris, Robert, Yamano, Makoto, Kinoshita, Masataka, Spinelli, Glenn, Hamamoto, Hideki, and Ashi, Juichiro
Abstract:: We review marine heat flow data along the Nankai Trough and show that observations >30 km seaward of the deformation front are 20% below conductive predictions (129–94 mW m⁻²) but consistent with the global heat flow average for oceanic crust of the same age (16–28 Ma). Heat flow values ≤30...
