GEOTRACES-related session:

HS8.2.7 : Submarine and Sublacustrine Groundwater Discharge
Convener: Ulf Mallast
Co-Conveners: Christian Siebert, Yossi Yechieli, Pieter van Beek, Jean Wilson
Link: http://meetingorganizer.copernicus.org/EGU2015/session/18450

Over the last years, near-shore and offshore submarine and sublacustrine groundwater discharge (more generally referred to as SGD) has been recognized as an important component of the hydrological cycle. Total SGD fluxes are proposed to be similar in or even exceed the volume of riverine flux in certain regions. These fluxes do not only comprise a significant water volume loss being essential for e.g. semi(-arid) regions and the increasing population and industrial water demands along coastlines, but likewise, can contain a significant concentration of nutrients, organic compounds and heavy-metals that may deteriorate coastal zone environments.
These aspects call for qualitative and quantitative SGD investigations on different temporal and spatial scales to gain reliable information that could be integrated into groundwater and coastal water management plans.

With the session we want to provide a basis for scientist from different disciplines to report about their approaches and results in regard to SGD. The session is not intended to cope with aspects of sea-water intrusion into aquifers but is focused on submarine or sublacustrine discharge and the herein involved processes and effects.

Topics include but are not limited to:
• Monitoring and measuring techniques (remote sensing, in-situ sensor arrays, seepage meter experiments, ACDP measurements etc.)
• Hydrochemical and microbacterial investigation concerning groundwater characterization
• Numerical modeling including aspects of recirculation, plume distribution and SGD quantification
• Ecological processes and effects
