The isotopic composition of carbon, δ13C, in seawater is used in reconstructions of ocean circulation, marine productivity, air-sea gas exchange, and biosphere carbon storage. Here, a synthesis of δ13C measurements taken from foraminifera in marine

Publikováno v: Earth and Planetary Science Letters
We report here the results of a multi-proxy study to reconstruct surface water pCO2 concentrations in the northern Arabian Sea. Our results show that [delta]11B and Mg/Ca measurements of the planktonic foraminifer Globigerinoides sacculifer yield con

A high-resolution calibration of Sr/Ca thermometry using the Caribbean coralMontastraea annularis
Autor: H. Elderfield, Mervyn Greaves, Peter K. Swart
Publikováno v: Geochemistry, Geophysics, Geosystems. 3:1-11
[1] A relationship has been established between the Sr/Ca ratio in the skeleton of the scleractinian coral Montastraea annularis and sea surface water temperature in south Florida. In order to obtain this correlation, specimens of Montastraea annular

Strontium isotope stratigraphy of Kita-daito-jima Atoll, North Philippine Sea: implications for Neogene sea-level change and tectonic history
Autor: S. Ohde, H. Elderfield
Publikováno v: Earth and Planetary Science Letters. 113:473-486
A detailed chronology of a 432 m core from Kita-daito-jima, an atoll on the Philippine Sea plate, has been obtained by strontium isotope stratigraphy. The atoll carbonate extends to late Oligocene age. The top ∼ 100 m Plio-Pleistocene section of th

Helium, radon and manganese at the TAG and Snakepit hydrothermal vent fields, 26° and 23°N, Mid-Atlantic Ridge
Autor: H. Elderfield, Mark Rudnicki
Publikováno v: Earth and Planetary Science Letters. 113:307-321
3 He, 4 He and 222 Rn have been measured in samples of vent fluids from the TAG and Snakepit hydrothermal vent fields and in samples from the neutrally buoyant plume at TAG. The hydrothermal end-member 3 /He 4 He at TAG, normalised to the ratio in ai
