After a short revue on the biological exploration of Surtsey, 1964–1970, a report is given of a stay on Surtsey in 1969, the collecting of samples and the microbiological examination of the samples. The main problem is to recognize the pioneer organisms of the colonization of the ashes, the tephra and lava away from the coast where no permanent accumulation of fresh water exists and the process of mechanical and chemical weathering is just beginning. Several biotops have been characterized by germ numbers and biochemical groups of bacteria. The most active, biologically, was the biotop of the fumaroles. The results have been discussed and a program for further exploration has been outlined.
