In 1963, fishermen off the southern coast of Iceland saw something unusual. The sea was bubbling and smoking. Within days, dark rock began rising above the surface. A volcanic eruption had started beneath the ocean, and over the next few years it built a brand-new island. That island was named Surtsey.
From the beginning, scientists realised this was a rare opportunity. Islands usually form far from human eyes, and by the time people arrive, plants and animals are already established. Surtsey was different. It was born in modern times, with researchers ready to observe every stage.
To keep the island as natural as possible, Iceland decided to restrict access. Only scientists are allowed to visit, and even they follow strict rules. The goal is to study how life colonises new land without interference. Seeds arrive by wind, birds carry plant material in their feathers or droppings, and insects drift in from the mainland. Over time, bare lava slowly turns into soil, and simple plant life begins to spread.
Because almost no one walks on Surtsey, the island acts like a living laboratory. Researchers can track exactly how ecosystems begin from scratch. It is one of the few places on Earth where scientists can watch nature build itself step by step.
Surtsey does not “belong” to scientists in a legal sense. It belongs to Iceland. But it is protected for research so that its story remains as untouched as possible.
