Galapagos Hydrothermal Vents 9 F       0.072 0.074     Edmond et al. 1979
Galapagos Hydrothermal Vents 14 Si       0.165 0.775     Edmond et al. 1979
Galapagos Hydrothermal Vents 56 Ba       0.15 1.1     Barium concentration observed at the Galapagos Islands, which is a model for flux of Ba at hydrothermal ridge areas. Concentration values were calculated by Isotope dilution mass spectrometry at MIT campus. Edmond et al. 1979
Galapagos Hydrothermal Vents 37 Rb       1.32 1.88     Rubidium concentration range as is found at the Galapagos hydrothermal resirvoir. Concentrations used as a model for hydrothermal activity of minor elements in the ocean and are compared to concentrations found in major rivers and basalts. Rubidium is similar to Lithium in terms of its activity at the hydrothermal ridge crest where it is most enriched in deep sea clays. In comparison to values from rivers it is seen that Rb values in the ocean are roughly 4-7x greater. All values of Rb obtained by Isotope dilution mass spectrometry at MIT. Edmond et al. 1979
Galapagos Hydrothermal Vents 19 K       10.08 10.37     Potassium concentration range as studied at the Galapagos hydrothermal resirvoir as a model for ridge crest hydrothermal activity of minor elements. Concentrations increase as a function of temperature and the hydrothermal flux of Potassium is 65% of that which emits from continents. The major Potassium sink (that is seen in the Galapagos) is most likely due to low temperature alteration of oceanic crust which could very likely be attatched to all locales, not just hydrothermally active areas. Values obtained according to Microgravimetry as the tetra phenyl borate on pre weighed Nucleopore filters at MIT. Edmond et al. 1979
Galapagos Hydrothermal Vents 20 Ca       10.31 11     Calcium concentration observed at the Galapagos Islands which is used as a model for hydrothermal ridge activity of major and minor elements in the ocean. Calcium concentrations were obtained via EGTA/EDTA titration, electrometric endpoint, Hg electrode at MIT. Edmond et al. 1979
Galapagos Hydrothermal Vents 16 S       27.39 28.55     Edmond et al. 1979
Galapagos Hydrothermal Vents 17 Cl       34.41 34.74     Edmond et al. 1979
Galapagos Hydrothermal Vents 12 Mg       51.1 52.7     Magnesium concentration range as observed during this study of hydrothermal ridge activity. All values determined via EGTA/EDTA titration, electrometric endpoint, Hg electrode at MIT. Edmond et al. 1979
Galapagos Hydrothermal Vents 3 Li       28 59     Lithium concentration range at the Galapagos hydrothermal resirvoir. Considered a cyclic salt due to its input and impending uptake during low temperature alteration of the oceanic crust. Range values obtained according to Atomic Absorption Spectroscopy with internal additions performed at MIT. Edmond et al. 1979
