Summary
Submarine groundwater discharge (SGD) is the flow of fresh or recirculated groundwater into the ocean. This process introduces substantial amounts of nutrients to coastal areas, which significantly influences ecological systems. In karstic settings SGD dominantly occurs from submarine springs that manifest as point source discharge sites. Their identification generally relies on sea-surface changes (e.g. visual sea-surface anomalies or changes in sea-surface temperature) and is therefore confined to shallow areas with high discharge rates. As a result the distribution of offshore freshwater springs in karstic environments, which is crucial for determining the architecture and dissemination of offshore groundwater systems, is usually poorly constrained. Similarly, the negative effects of groundwater springs on seagrass diversity and biomass have been investigated at individual springs but have not been characterised over larger areas. This proposal focuses on the identification, characterisation and distribution of submarine springs and their influence on local ecosystems in karstic environments. KARST will make use of state of the art geophysical and remote sensing techniques for optimal imaging at various depths. In the shallow coastal areas (
