Data for: Investigating the molybdenum and uranium redox proxies in a modern shallow anoxic carbonate rich marine sediment setting of the Malo Jezero (Mljet Lakes, Adriatic Sea)

Table 1. H2S concentrations in Malo Jezero water column from 1951 to 1961 (concentrations were taken from Buljan and Špan, 1976).
Table 2. Vertical distribution of trace elements (Al, Ti, Li Sr Mo, U and V) and CaCO3 content (wt%) in Malo Jezero sediments from 30, 20 and 13 m depth. Porewater Mo, U, Fe and Mn concentrations were taken from Sondi et al. (2017) while the porewater [H2S] was obtained within this study as described within the ‘methods’ section.
Table 3. Al, Ti, Li, Sr, Mo, V and U concentrations in the catchment Malo Jezero samples as well as dissolved Mo and U concentrations in the Malo Jezero water column (0, 12 and 25 m depth).
Table 4. Sedimentary Mo and U bulk isotopic composition (δ98Mobulk and δ238Ubulk) as well and 234U/238U activity ratio, (234U/238U)act in Malo Jezero sediments from 30, 20 and 13 m depth. The isotopic composition of U and Mo in Malo Jezero water samples taken from 0, 12 and 25 m depth and catchment soil samples (terra rossa and humus soil) are given together with the corresponding (234U/238U)act.
Table 5. Sedimentary Mo and U authigenic isotopic composition (δ98Moauth and δ238Uauth) as well and sedimentary Mo and U authigenic concentration ([Mo]auth and [U]auth) in Malo Jezero sediments from 30, 20 and 13 m depth.
Table 6. Sedimentary lithogenic Mo and U fractions ([Mo]lith and [U]lith – estimated using linear regression equations presented in Figure 3, Molith/Al and Ulith/Al ratios and estimated Mo and U enrichment factors (MoEF and UEF).
