Recent advances in the study of coastal groundwater: Argentona research site and geophysical in the land-ocean transition zone.
Abstract: Coastal groundwater is important not only as a water resource for shore populations, but also as a source of solutes and nutrients to coastal ecosystems. To improve understating in the processes taking place in the land-ocean interface, the GHS together with other national and international research groups, developed a unique highly monitored research site in a coastal aquifer (15 boreholes in 60X40 meters). For a period of 10 years several geophysical, hydraulic, (bio)geochemical methods and techniques have been applied to the research site in order to study sea water intrusion and submarine groundwater discharge. In 2020, the site the was improved with the construction of new boreholes, applying new isotopic, chemical and microbial techniques and the area of investigation was increased applying different geophysical techniques offshore. In this seminar, we will explain: 1) the improvements of the site, open to the research community, with recent and ongoing related advances and 2) the initial results of different geophysical techniques applied in the land-ocean transition zone and offshore in different study areas.
