Description: The Core Samples feature class is a collection of sediment core and borehole locations and their respective summary attributes. These data were compiled from multiple agencies conducting investigations and studies relevant to outer continental shelf (OCS) non-energy mineral resource (e.g. sand, gravel, shell) management. Many of these efforts were funded at least partially by the Bureau of Ocean Energy Management (BOEM) (formerly known as the Minerals Management Service). The summary information for each core and boring location includes (but is not limited to) core/borehole ID, state, date/time, x/y coordinates (and horizontal datum), method of sampling, sampling device, elevation (and vertical datum), penetration depth, percent recovery, study name, and source agency contact information. Digitized core/borelogs and sediment sample data (if available; e.g. layer descriptions, grain-size analyses, Munsell color, etc.) are contained in the related Core Layers and Samples tables, respectively. The associated study report(s) are linked via the Link Documents table. This feature class will be updated as new data are received.
Description: The Geological Survey of Alabama contracted the APTIM Team to conduct a reconnaissance geophysical and geological survey. This project is funded by the Resources and Ecosystem Sustainability, Tourist Opportunities, and Revived Economics (RESTORE) of the Gulf Coast States Act of 2012 under the “State Expenditure Plan #5: Characterization and Delineation of Significant Sand Resource Areas Essential for Beach Restoration”. Alabama offshore sand reserves are essential to the maintenance of amenity beaches, to the intertidal and beach ecosystem functions, and to the services beaches provide. The purpose of this project is to locate and identify beach compatible sands which can aid in future beach restoration projects for the State of Alabama by initiating a bathymetric and sand sediment sampling and analysis program. This project collected 123 nm (228 km) of high-resolution geophysical data aboard Florida State University’s (FSU) R/V Apalachee. These data were collected between January 13 and January 19, 2024. To properly address GSA’s needs as well as state and local agencies, APTIM first conducted a detailed desktop study in the area. The desktop study is part of Phase 1 and is intended to identify historical datasets and reports within the area of interest that help to clarify the geological framework and potential resources within the area. Once the results of the desktop study were reviewed and study areas and plans established, APTIM proceeded to Phases 1 and 2, which included geophysical and geological data collection. Geotechnical data was collected between September 14 and October 1, 2024.
Description: The Grab Samples feature class is a collection of sediment grab locations and their respective summary attributes. These data were compiled from multiple agencies conducting investigations and studies relevant to outer continental shelf (OCS) non-energy mineral resource (e.g. sand, gravel, shell) management. Many of these efforts were funded at least partially by the Bureau of Ocean Energy Management (BOEM) (formerly known as the Minerals Management Service). The summary information for each grab location includes (but is not limited to) grab ID, state, date/time, x/y coordinates (and horizontal datum), sampling device, elevation (and vertical datum), penetration depth, study ID, and source agency contact information. Laboratory analyses of sediment sample data (if available; e.g. textural classification, grain-size analyses, Munsell color, etc.) are contained in the related Samples table. The associated study report(s) are linked via the Link Documents table. This feature class will be updated as new data are received.
