We are hosting a workshop/discussion group to address hydrogeologic issues related to Leaky Coastal Margins.
This event will take place concurrent to the Karst Interest Group (KIG) information transfer meeting (agenda available) in February 2001.
Purpose:

Example: A leaky coastal margin, from central Florida. large version

Organize a small group of invited scientists (USGS-wide, state, and other agencies/academia) that have
expertise in linking hydrologic and geologic processes in coastal carbonate settings. One 'product' of this
forum is to create a solid research agenda that includes key biologic, hydrologic and geologic components
important to Leaky Coastal Margins.
Background:
Leaky Coastal Margins (LCM) are defined here as a land-sea boundary in carbonate-based environments
where the underlying geologic framework consists of karstic features that uniquely define coastal
hydrogeologic processes. For example, extreme bedrock transmissivities, conduit flow, offshore seeps/springs
all complicate a sound understanding of coastal aquifer systems, especially in regards to coastal ground
water quality issues such as saltwater intrusion and reservoir capacity.
This workshop will focus
specifically on such LCM where the underlying geology is predominantly carbonate limestone, and where
the land-sea boundary often includes an additional complex subterranean/submarine component. Specific
themes that have current relevance in the USGS Strategic Plan such as: karstic wetland evolution,
pollution, ground water quality/quantity and coastal eutrophication, will be addressed first by a
series of keynote speakers, and then by an informal discussion group. Proceedings from this workshop
will help direct future USGS research efforts and collaborations to address the scientific implications
of Leaky Coastal Margins.
Objectives:
- To compare/contrast a wide range of geochemical techniques and equipment for coastal hydrogeology;
- To design an interdisciplinary research program that can successfully address most relevant issues
of Leaky Coastal Margins.
