Östergarnsholm

Östergarnsholm is an uninhabited island off the eastern coast of Gotland used as a research station for climate and environmental studies. The island houses several measurement instruments and features a tall tower for collecting data from the air and sea.

The research facility on the island was established in the 1990s to conduct systematic observations of Baltic Sea conditions. Since then it has provided continuous data about climate and environmental changes in this marine region.

Scientists from multiple institutions conduct essential climate research on this isolated island, contributing to international databases and environmental understanding.

The island is uninhabited and accessible only for scientific work, not open to visitors. The facility operates independently using wind turbines and solar panels that enable year-round measurements.

The station monitors carbon exchange between the sea and atmosphere, capturing different patterns across seasons. During warmer months the sea absorbs carbon dioxide, while in colder periods it releases it back.
