The invisible carbon in Ireland’s waters

Dissolved organic carbon may be one of the most underestimated pressures on Irish waters. About 20% of our land area is covered by peat and peaty soils, which are among the most carbon-rich ecosystems on Earth. That makes Ireland uniquely vulnerable to large losses of carbon from land to water
