6th Future Ocean Network Event: Land‐Ocean Connectivity through Groundwater

Jun 11, 2021 from 12:30 PM to 02:00 PM

Land‐Ocean Connectivity through Groundwater
We will provide insights into the social relevance of coastal groundwater interactions, present the current state for research, and discuss ideas of cross‐disciplinary engagements of Kiel scientists to help understand, monitor, manage and govern coastal groundwater under changing climatic conditions.

Open discussion
moderated by Prof. Dr. Nele Matz‐Lück

The quality of freshwater aquifers around the world is deteriorating due to overexploitation, salinization, as well as contamination with agricultural fertilizers. In coastal regions, this pressure is amplified by seawater encroachment due to sea‐level rise, precipitation shift, extreme storm events, and groundwater pumping. The exploitation of offshore freshened groundwater has been proposed as a potential freshwater source to mitigate seasonal water shortages in coastal regions most affected by low quality drinking water. At the same time, discharging terrestrial groundwater transports water and dissolved constituents to the coastal ocean, and can strongly affect coastal ecosystems. The flux of Fresh Submarine Groundwater Discharge (FSGD) exceeds river flux in many coastal areas and thus poses a serious risk of pollution and eutrophication for a significant fraction of coastal ecosystems such as estuaries, salt marshes and coral reefs. Examples of seawater intrusion into coastal aquifers, groundwater‐dominated coastal ecosystems, and the use of offshore groundwater as potential drinking water highlight that groundwater and ocean are intimately connected.
