FY 2000 The water-column chemical signature after the 1998 eruption of Axial Volcano Resing, J.A., R.A. Feely, G.J. Massoth, and E.T. Baker Geophys. Res. Lett., 26(24), 3645–3648, doi: 10.1029/1999GL002350 (1999) The eruption of Axial Volcano in January 1998 produced extensive plumes in the overlying water column with large anomalies in Fe, Mn, pH, light attenuation, and temperature. A strong correlation between total iron and light attenuation (dc) suggests a low abundance of particulate sulfur (PS) in the plumes. Because total carbon dioxide (ΣCO2) samples were not collected, high-precision pH measurements were used to estimate maximum CO2 anomalies (ΔCO2) which, when compared to the other physical and chemical data, suggest that the fluids being vented 3 weeks after eruption were formed by the interaction between an intruded dike and a mixture of interstitial seawater and mature hydrothermal fluids.
