Does 234Th/238U disequilibrium provide an accurate record of the export flux of particulate organic carbon from the upper ocean?
The magnitude of the flux of biogenic particulate organic carbon (POC) exported from the surface waters of the world ocean and remineralized at depth is critical to constraining models of the global carbon cycle, yet remains controversial. The use of upper ocean sediment traps is still one of the primary tools for determining this export flux, although trap fluxes have been shown to vary signif...

متن کاملHow does Product Innovation Affect Export Margins?
The previous studies on the factors affecting trade margins emphasize the importance of exogenous trade costs; however, the role of product innovation has not been thoroughly investigated. Product innovation activities of a firm directly determine how efficiently its product matches the target consumers’ preferences and in turn significantly affects a country's trade growth patter. Therefore, w...
متن کاملHow Does Spatial Study Design Influence Density Estimates from Spatial Capture-Recapture Models?
When estimating population density from data collected on non-invasive detector arrays, recently developed spatial capture-recapture (SCR) models present an advance over non-spatial models by accounting for individual movement. While these models should be more robust to changes in trapping designs, they have not been well tested. Here we investigate how the spatial arrangement and size of the ...
متن کاملUpper ocean carbon flux determined by the 234Th approach and sediment traps using size-fractionated POC and 234Th data from the Gulf of Mexico
Size-fractionated particulate 234Th and particulate organic carbon (POC) fluxes were measured in the Gulf of Mexico during 2000 and 2001 in order to obtain a better estimation of upper ocean organic carbon export out of the euphotic zone within cold core and warm core rings, and to assess the relative merit of sediment trap and POC/234Th methods. In 2000, the flux of POC measured by sediment tr...
