Volcanic influence on seawater at Heimaey

VOLCANISM is a contributing factor in marine geochemical processes. It has been shown to contribute to the dissolved silicon in seawater¹, it has also been suggested as the cause of some anomalous fluoride concentrations observed in the sea² and it has been seen as a possible source of manganese, iron and other elements found in unusual concentrations in manganese nodules and some deep sea sediments^3,4. Moreover, it has been suggested that in the geological past volcanism has affected the microfauna of large oceanic areas⁵. Here I describe the effect of the recent Heimaey eruption on the waters nearby.
