The Project aims to obtain long-term data series from seagrass sedimentary archives in the Mediterranean region to answer key environmental and management questions. Globally, billions of euros are spent on understanding ecosystem services and responses to human and natural pressures, but the short time-span of contemporary datasets means they are often inadequate, since ecosystem changes occurs at multiple spatial and temporal scales. The Project aims to use seagrass archives to reconstruct the history of coastal ecosystems over millennia, identifying baseline conditions, the time-course of ecological change, cycles and thresholds of ecosystem dynamics driven by human and natural forces, and determining the role of seagrasses as biogeochemical sinks in the Mediterranean region.
