Age correction according to 232Th concentration and a seawater 230Th/232Th ratio of 8±4. Age correction is negligible within the uncertainties for all data. Laboratory...

This dataset contains 48 U-Th ages of 14 speleothems used to reconstruct past sea level between 9ka and 421ka ago. They were collected from submerged caves in an area (<20...

U-series datings were performed on Lophelia pertusa cold-water coral fragments.

Combined 230ThU and 14C ages in cold-water corals allow accurate reconstruction of ventilation in the past. Here we present a ventilation record of cold-water corals from...

Compilation of cold-water coral dated by U-series or radiocarbon of Northeast Atlantic Ocean. Age column corresponds to reported U-series corrected ages or calendar 14C ages...

The dataset presented here captures 114 uranium isotope ratio (234U/238U), expressed as δ²³⁴U, in a coral from northern Cuba, with data spanning the past 230 years. The primary...

The error is 2s error. U decay constants: l238 = 1.55125x10-10 (Jaffey et al., 1971) and l234 = 2.82206x10-6 (Cheng et al., 2013). Th decay constant: l230 = 9.1705x10-6 (Cheng...

Presented here are U-Th ages derived from the MV30 stalagmite. This sample was collected from Mata Virgem cave (11°37′27.07′′S, 47°29′19.04′′W) in the eastern region of the...

Presented here are U-Th ages derived from the MV1 stalagmite. This sample was collected from Mata Virgem cave (11°37′27.07′′S, 47°29′19.04′′W) in the eastern region of the...

Sediment depth is given in mcd. Raw age is calculated directly from the data in the previous two columns. Scavenging corrected age = the age corrected for initial 230Th by...

U and Th blanks are <1‰ of the measured sample and are corrected for. Raw ages and delta234U values are adjusted to account for initial 230Th to give the corrected numbers in...

U and Th blanks are <1‰ of the measured sample and are corrected for. Raw ages and delta234U values are adjusted to account for initial 230Th to give the corrected numbers in...

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...

Uranium series dated cold-water corals from Tropic Seamount, Reykjanes Ridge, and East Equatorial Atlantic. Ages are reported in years before present (BP; where present is the...

Uranium-thorium dating offers the possibility of absolute age determination of cold-water corals (CWCs). We present here the complementary dataset to "Radiocarbon dating of...

Notes: All given statistical errors are two standard deviations of the mean (2Sigma). The used decay constants are: Lamda234U = 2.8262 x 10-6 a-1 (Cheng et al., 2000b);...

Age corr.: Age correction according to 232Th concentration and 230Th/232Th ratio of 8±4.Laboratory code/label IUPH: Institute for Environmental Physics, University of...

The dataset includes speleothem U-Th ages used to reconstruct climate in southeastern Alaska during the past ~3,500 years. Speleothem WB-21-5-A was collected in Wishbone Cave...

The data sets include U-series and Neodymium isotope measurements in modern (n = 6) and fossil (n = 24) deep-coral (Desmophyllum dianthus) assemblages raised from the Orphan...
