Updating the mapping of seagrass and saltmarsh areas in the Algarve's four wetlands. Sampling sediment and biomass in these ecosystems to assess carbon content and sequestration capacity. Creation of a complete blue carbon database of these four ecosystems and therefore an estimate of the total blue carbon available on the Algarve coast.

The seagrass and salt marshes of the Algarve store the equivalent of 1.58 million tonnes of carbon dioxide, an amount that corresponds to the annual emissions of 343,000 cars (5% of all vehicles in circulation in Portugal).
