Collects and interprets statewide surface and subsurface geophysical and geological data
The Geological Investigations Section of the Florida Geological Survey collects and interprets surface and subsurface
geologic data within upland, offshore, near shore, beach and estuarine environments to provide an understanding of
Florida’s three-dimensional geologic framework. This knowledge is necessary
to understand Florida’s ecosystems, watersheds, aquifer recharge and protection, and to provide or recommend effective
environmental remediation, where necessary.
Statewide coastal research is a part of the Geological Investigations Section that is
cooperatively funded by various federal agencies including the U. S. Geological Survey, the U.S. Bureau of Ocean Energy
Management, Regulation, and Enforcement, and the Environmental Protection Agency. These studies commenced 1991 in recognition
of the need for geologic information to further our understanding of coastal processes, resources and fragile coastal ecosystems.
Conducts statewide geologic, geomorphic and mineral resource mapping
The Geological Investigations Section works with the FGS Geological Sample Acquisition and Management
Section acquiring geological data and samples through auger and core-drilling supporting existing FGS research. Staff describe
these cores and cuttings as well as those archived in the FGS repository. The descriptions are entered into the FGS
lithologic database, which presently contains more than 5,000 records. These
descriptions are then used to create statewide maps.
The FGS statewide Geological Mapping Program (STATEMAP)
program was established in 1994. Its mission is "to establish a geologic framework through detailed mapping of areas determined
to be vital to the economic, societal, or scientific welfare of Florida. STATEMAP recently completed a project near St. Augustine.
The geomorphology of Florida is unique. As one of two states residing entirely within the Coastal Plain, Florida is part of
an enormous carbonate bank, called the Florida Platform, covered by a thin layer of younger quartz sand and clay sediments.
It is these carbonate rocks which are, in part, responsible for many of the karst features common to Florida, such as springs,
swallets and sinkholes. Identifying these landforms and completion of the
statewide geomorphic mapping project is important
for Floridians to better understand the state’s geologic history and why the landscapes of Florida occur where they do.
Conducts geologic hazard research
The section documents potential hazards such as coastal erosion and sinkholes, and currently maintains a database of statewide
Subsidence Incident Reports
Investigate and report on Florida’s stratigraphy, mineralogy, sedimentology, and paleontology
Research conducted by the Geologic Investigations Section sustains the core statutory mandate of FGS and includes: statewide
geologic mapping; reinterpretation of Florida’s geomorphic features; and aquifer-system framework delineation. Additional
functions of the section include compiling up-to-date mineral assessments as well as maintaining information on Florida’s
Provides geological expertise
Cores, cuttings, lithologic descriptions and geophysical logs are a valuable asset to the earth science community. These
fundamental geologic data support the needs of more than one third of the programs in the Florida Department of Environmental
Protection. The Geological Investigations Section provides geological expertise to these programs. When issues arise that
might impact or be impacted by the geology of Florida, the staff also acts as consultants or co-investigators to other local,
state and federal agencies.
Provides outreach and education opportunities for citizens highlighting the importance of geoscience
The FGS actively participates in educational opportunites throughout the year: presenting geologic information to citizens
and government officals; speaking to both local schools and institutes higher education; and developing posters and pamphets
that are used throughout the state to educate the public.
