Uranium, Thorium and Protactinium isotopes of ODP Site 172-1063
Ocean circulation may have undergone reductions and reinvigorations in the past closely tied to regional climate changes. Measurements of 231Pa/230Th ratios in a sediment core... -
Activity of isotopes of U, Th and Pa versus depth in bottom sediments from Co...
A sediment core from the European Basin with alternation of biogenic calcareous oozes and terrigenous sediments is studied by several methods. Isotopic age is determined by... -
(Table S1) Uranium and Thorium isotopes and U/Th ages of IODP Exp310 cores fr...
The timing of sea-level change provides important constraints on the mechanisms driving Earth's climate between glacial and interglacial states. Fossil corals constrain the... -
Uranium and strontium concentrations of ODP Hole 117-722B (Appendix B)
High resolution sampling of the upper 10 m of Hole 722B has provided information on the extent of 234U/230Th disequilibrium in Owen Ridge sediments accumulating over the last... -
(Table 2) Uranium concentrations and isotopic ratios in surface waters of the...
Uranium concentrations and isotope ratios were measured in thirteen surface-water samples collected across the entire Atlantic Ocean. The mean isotope ratio was 1.15+/-0.01, and... -
U and Th concentrations and U-TH ages for bulk carbonate samples from ODP Hol...
Thirty-one new bulk-sediment U–Th dates are presented, together with an improved d18O stratigraphy, for ODP Site 1008A on the slopes of the Bahamas Banks. These ages supplement... -
(Supplementary Table 1) 230Th/U results for stalagmite Cuba Grande (CG) from ...
We present 22 U-series ages for a stalagmite from north-western Cuba based on multi-collector inductively coupled plasma mass spectrometry (MC-ICPMS) and thermal ionisation mass... -
(Table 1) Th and U concentrations and activity ratios in deep-sea sediments a...
The Labrador Sea is a particularly suitable high-latitude basin for investigating U and Th behavior in deep-sea sediments. During the late Quaternary, the cyclic development and... -
Radionuclides measured on 37 water bottle profiles during POLARSTERN cruise A...
The loss of Arctic sea ice has accelerated in recent years. With the decline in sea ice cover, the Arctic Ocean biogeochemistry is undergoing unprecedented change. A key... -

Th-U ages of a stalagmite from the Kleegruben Cave (Table 1)
A mass-spectrometric uranium-series dated stalagmite from the Central Alps of Austria provides unprecedented new insights into high-altitude climate change during the peak of...
