Abstract

The influence of the recent Surtsey eruption on the nutrient content of the surrounding seawater was studied over a period of one year. During the first months, while the eruption was explosive and when seawater flooded the vents, a significant increase in reactive silicates was observed within 30 km of the eruption center, and the silicate concentration had increased by a factor of three near the island. After the eruption changed to an effusive phase, in early April 1964, the amounts dissolved were negligible, except close to the island where bot lava entered the sea....
