Florida Geological Survey receives national grant to map in NE Florida

Grant will increase knowledge of geology, which helps improve land-use planning in northeastern area of Florida

TALLAHASSEE – The Department of Environmental Protection’s Florida Geological Survey has been awarded $193,183 by the U.S Geological Survey to produce a detailed geologic map of a portion of northeast Florida. The STATEMAP grant is the fourth-highest award amount distributed nationwide this year for work that will begin in September and is expected to be publicly available for digital download by December 2014.

“The funding provided by the USGS allows us to produce a geologic map in support of the societal, economic and scientific welfare needs of Florida,” said STATEMAP Project Manager Rick Green. “Our goal is to make these findings readily available and accessible to the public.”

The benefits of this type of mapping include a more comprehensive understanding of the distribution of rock, mineral and groundwater resources, including vulnerability of aquifers to contamination. These maps are also important in providing shallow subsurface geological information that can be used in understanding sinkholes and other geologic hazards.

The mapping effort involves extensive field work over a 12 month period, including visits to accessible rock and sediment exposures in mines and other excavated areas, as well as natural exposures in rivers, streams, sinkholes and springs. To better understand the underlying geologic units, project staff inspect rock and sediment samples from hundreds of wells, including new wells drilled in support of the project to fill data gaps. Extensive data management and map making in a geographic information system platform is also involved.

This work is conducted under the STATEMAP component of the National Cooperative Geologic Mapping Program, which serves to create a national geologic database that is accessible to the public. The STATEMAP Advisory Council, which is comprised of geologists and engineers in Florida, prioritized the St. Augustine quadrangle as the primary focus for this year’s work.

The approximately 2,000 square mile area was approved due to its location adjacent to current project mapping underway in the Daytona Beach area, as well as an additional project being conducted along the northeast coast of Florida funded by the National Park Service and Florida Geological Survey. This will allow the Florida Geological Survey to maximize its resources and expand upon existing data.

Since its inception in 1994, this component of the National Cooperative Geologic Mapping Program has funded more than $4.6 million in support of mapping to benefit Florida’s residents and environment, covering an area of more than 13,000 square miles.

Data gathered by the STATEMAP program is also used by other agencies in Florida. The Florida Department of Transportation used information from mapped STATEMAP projects for an assessment of strategic aggregate reserves in the state and to develop a better understanding of the geology in support of projects, such as the Florida Future Corridors program.

The maps are published annually and released in segments online.
