Radioactive isotope analysis of sediment core PS115/2_2
Sediment Core PS115/2-2 was recovered from the Amundsen Basin in 3600 m water depth at the eastern flank of the Gakkel Ridge during Polarstern Expedition PS115/2 in 2018 (Stein,... -
Uranium-Thorium series of sediment core Arc7-E25
*230Thxs is calculated by the subtraction of mean activity value of 234U from the total 230Th. -
U-Series isotopes analytical results (U & Th) on core PS2757-8 (KAL)
Core PS2757-8 was taken with a Kastenlot corer (KAL) on the Lomonosov Ridge next to the Russian continental shelf during the Polarstern expedition ARK-XI/1 in 1995. This... -
U-Series isotopes analytical results (U & Th) on core PS2757-6 (MUC)
Core PS2757-6 was retrieved with a multicorer (MUC) on the Lomonosov Ridge next to the Russian continental shelf during the Polarstern expedition ARK-XI/1 in 1995. This... -

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... -
(Table 1) Composition of volcanic glasses from the East Scotia Ridge
New U-series isotope data for lavas from the East Scotia backarc spreading center span a large range in (230Th/232Th) and (238U/232Th). Most of the backarc lavas have... -

U-Th ages were calculated using the initial detrital 230Th/232Th value of 111 ± 41 ppm, which was previously calculated for SC02 based on two isochrons measured in separate... -
Uranium-Thorium analysis from IODP Site 323-U1340
The Bølling-Allerød deglacial event is marked by high diatom productivity and opal deposition throughout the subarctic Pacific. To investigate the cause of this event, we... -

This dataset accompanies a manuscript submission to Paleoceanography and Paleoclimatology, in which a new 230Th-dating method for deep-sea sediments in analogy with 210Pb-CRS... -
(Table 1) Uranium-Thorium datings from corals of Hainan Island, South China Sea
All isotopic ratios are activity ratios. Errors are quoted as 2 sigma. Half lives used in the calculation are as follows: 230Th, 77381 ± 590 (2s); 234U, 244600 ± 490 (2s);... -
