The use of 230Th-normalized fluxes reduces uncertainties that many prior studies faced by accounting for the effects of sediment redistribution by bottom currents and minimizing the impact of age model uncertainty. Here we employ a recently compiled global dataset of 230Th-normalized fluxes with an updated database of seafloor surface sediment composition to derive global maps of the burial flux of calcium carbonate, biogenic opal, total organic carbon (TOC), non-biogenic material, iron, mercury, and excess barium (Ba xs). The spatial patterns of burial of the major components are consistent with prior work, but the new quantitative estimates allow evaluations of global elemental budgets, refining prior assessments. Sedimentary Fe fluxes are largely consistent with the bulk non-biogenic burial flux, except in coastal settings or locations with significant hydrothermal inputs. The fluxes of some commonly used paleo-productivity proxies (TOC, biogenic opal, and Ba xs) do not demonstrate spatially-significant relationships with satellite-based productivity estimates Our new compilation of sedimentary fluxes provides more detailed information on burial fluxes, which should lead to substantial improvements in the understanding of how preservation affects these paleoproxies.","pubRank":"1"}],"site":[{"NOAASiteId":"58403","siteName":"Global Ocean Sites","siteCode":null,"mappable":"N","locationName":"Geographic Region>Global Ocean","geo":{"geoType":"Feature","geometry":{"type":"POLYGON","coordinates":["-90","90","-180","180"]},"properties":{"southernmostLatitude":"-90","northernmostLatitude":"90","westernmostLongitude":"-180","easternmostLongitude":"180","minElevationMeters":null,"maxElevationMeters":null}},"paleoData":[{"dataTableName":"Global surface sediments Hayes2020","NOAADataTableId":"43057","earliestYear":12100,"mostRecentYear":-52,"timeUnit":"cal yr BP","earliestYearBP":12100,"mostRecentYearBP":-52,"earliestYearCE":-10150,"mostRecentYearCE":2002,"coreLengthMeters":null,"dataTableNotes":"About 6% of the data have ages; others are assumed to be modern core-tops","species":[],"dataFile":[{"fileUrl":"https://www.ncei.noaa.gov/pub/data/paleo/contributions_by_author/hayes2020/hayes2020-surface-noaa.txt","urlDescription":"NOAA Template File","linkText":"Global Ocean Surface Sediment Data","variables":[{"cvDataType":"PALEOCEANOGRAPHY","cvWhat":"chemical composition>element or single-element molecule>zirconium","cvMaterial":"geological material>bulk geological material>sediment","cvError":null,"cvUnit":"concentration unit>parts per notation unit>parts per million","cvSeasonality":null,"cvDetail":null,"cvMethod":null,"cvAdditionalInfo":null,"cvFormat":"Numeric","cvShortName":"Zr"},{"cvDataType":"PALEOCEANOGRAPHY","cvWhat":"chemical composition>element or single-element molecule>mercury","cvMaterial":"geological material>bulk geological material>sediment","cvError":null,"cvUnit":"concentration unit>parts per notation unit>parts per billion","cvSeasonality":null,"cvDetail":null,"cvMethod":null,"cvAdditionalInfo":null,"cvFormat":"Numeric","cvShortName":"Hg"},{"cvDataType":"PALEOCEANOGRAPHY","cvWhat":"formation property>formation rate>accumulation rate","cvMaterial":"geological material>bulk geological material>sediment","cvError":null,"cvUnit":"rate unit>mass per area per time unit>gram per square centimeter per kiloyear","cvSeasonality":null,"cvDetail":null,"cvMethod":null,"cvAdditionalInfo":"thorium-230-normalized sediment flux; Flux is an interpolated value based on the site's location and water depth","cvFormat":"Numeric","cvShortName":"Mass_Flux"},{"cvDataType":"PALEOCEANOGRAPHY","cvWhat":"sampling metadata>notes","cvMaterial":null,"cvError":null,"cvUnit":null,"cvSeasonality":null,"cvDetail":null,"cvMethod":null,"cvAdditionalInfo":"Note on type of method used of biogenic opal analysis; MF89 = Mortlock & Froelich (1989); D81 = DeMaster (1981); XRD = X-ray Diffraction; MS93 = Mueller & Schneider (1993); SS = Smear Slide Analysis; SiAl = normative calculation based on measured silicon and aluminum; CE68 = Chester & Elderfield (1968); 0_1NNaOH = Alkaline leach method using 0.1 N sodium hydroxide; MA04 = Michalopoulos & Aller (2004); %5NaCO3Leach = Alkaline leach method using 5% sodium carbonate solution; FTIR = Fourier Transform Infrad Analysis; 1MKOH = Alkaline leach method using 1 M potassium hydroxide; L88 = Lyle et al.
