Abstract:
New benthic foraminifera stable isotope data from Site IODP U1302. The data range from core top to the LGM (~ 22 ka BP at 3.73 metres composite depth). Benthic foraminifera from the grain size fraction >106 μm were analysed for their stable carbon and oxygen isotope signatures. Two different species were used separately: Hoeglundia elegans (HE) and Uvigerina spp. (U.spp). The raw data are measured isotopic signatures relative to VPDB and the data columns d18Ob and d13Cb (b for benthic) are the same values corrected for vital effects following refs [1,2,3] with the correction factors given in the correction columns, in per mil. Ages are given in ka BP and time slice interevals are indicated in the column time.
