The SecuCoast project produces significant new understanding of groundwater and seawater interactions to enhance the management of coastal aquifers and marine ecosystem services under the cumulative human and climate change pressures. ​ ​

SecuCoast explores the groundwater-seawater interaction from three perspectives:
-The impact of sea water intrusion (SWI) on coastal groundwater quality.
-The impacts of submarine groundwater discharge (SGD) on the coastal sea ecosystem and ecosystem services.
-The corrosion risk of underground infrastructure by SWI and the liquefaction risk of seafloor infrastructure due to SGD.

SecuCoast covers wide spatial (Baltic Sea, Mediterranean Sea, Northern Atlantic) and temporal (seasonal to the last glacial cycle) scales scales.

Secucoast will apply a novel combination of recently-developed geophysical survey methods (FloaTEM, amphibious ERT) and sophisticated (isotope and radio)chemical analyses, microbiological and macrofaunal studies, and top-notch reactive transport modeling to better constrain and understand SWI and SGD and their effects to potable water abstraction and to eutrophication and acidification of coastal seas and consequences on marine ecosystem services.

The novel modeling capabilities allow the coupling to external physical forcings (e.g. sea-level rise and glacial dynamics), improving the prediction of groundwater systems for the foreseeable environmental changes over wide spatial and temporal scales. Our results help mitigate the pressures of human activities and climate change on coastal aquifers and coastal sea ecosystems.

​SecuCoast contributes to the UN Sustainable Development Goals (SDG 6, Clean water and sanitation; SDG 12, Responsible consumption and production; SDG 13, Climate action; SDG 14, Life below water).
