Element ratios from XRF-scan of sediment core MVSEIS08_TG-2 from Gulf of Cadiz

The content of a series of elements, included Zr (30 kV) and Ca, Al, Si, Fe (10 kV), were measured by non-destructive, continuous X-ray fluorescence (XRF) in cts (counts per second per unit area) every 1 cm, using an Avaatech core scanner at the University of Barcelona

Reflectance of sediment core MVSEIS08_TG-2 from Gulf of Cadiz

Optical properties of sediment give 2 RGB colour combinations (L*a*b* system for sediment color analyses) which characterize particular features of the mineralogical and geochemical composition of the sediment. The CIE (Commission Internationale d'Eclairage) L* lightness parameter, partly correlated with CaCO3, organic carbon and oxides content, was measured with a Linescan V1.8 of Avaatech, in the visible spectrum, lens aperture of 8 mm, 5 msec time of exposure, and space resolution of 0.07m, at the University of Barcelona, Spain

Stable isotopes of planktonic and benthic foraminifera of sediment core MVSEIS08_TG-2 from Gulf of Cadiz

For stable O and C isotopes analysis, 25 planktonic and 10 benthic foraminifera of the species Globigerina bulloides and Cibicides pachyderma were picked primarily in the fraction >250 μm, and occasionally in the interval 150–250 μm, in 113 samples, at the IGME. The analyses were performed in a Finnigan MAT 252 mass spectrometer at Marum (University Bremen, Germany), coupled to an automated Kiel-carbonate preparation system. The long-term precision is ±0.07‰ for δ18O and ±0.05‰ for δ13C based on repeated analyses of internal and external (NBS-19) carbonate standards. The stable O and C ratios are expressed as δ in permil (‰), relative to Vienna Peedee Belemnite (VPDB) standard. Nine duplicated samples in TG2 give a standard deviation between 0.07 and 0.12‰
