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...

Eastern Pacific Warm Pool paleosalinity and climate variability: 0–30 kyr

Creator:: Benway, Heather M., Mix, Alan C., Haley, Brian A., and Klinkhammer, Gary P.
Abstract:: Multiproxy geologic records of δ18O and Mg/Ca in fossil foraminifera from sediments under the Eastern Pacific Warm Pool (EPWP) region west of Central America document variations in upper ocean temperature, pycnocline strength, and salinity (i.e., net precipitation) over the past 30 kyr. Although evident in the paleotemperature record, there is...

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...

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...
