The following are a few representative geotechnical vibracore projects Athena has completed.
Hatteras Inlet Geotechnical Vibracoring
Athena collected 15 vibracore samples at Hatteras Inlet, North Carolina for a geotechnical pre-dregde assessment of sediments at the inlet. Athena was able to collect the cores while working in challenging conditions created by the close proximity to the surf-zone. Athena was charged with vibracore collection, core logging, core photography, laboratory oversight, and reporting of results.
Stono Inlet Borrow Area Evaluation
Athena collected 25 vibracores in the vicinity of Stono Inlet, on the western end of Folly Beach, South Carolina as part of an ongoing effort to expand sand borrow areas for use for beach renourishment at Folly Beach. Athena provided geological logging, core photography, and laboratory oversight during this project.
Folly Beach Borrow Area Evaluation
Athena completed a large-scale geotechnical evaluation sediments offshore and in the vicinity of Folly Beach, SC. 170 vibracores were collected offshore for the U.S. Army Corps of Engineers in order to delineate sand resources offshore and an additional 40 vibracores were collected in the vicinity of Stono Inlet under a contract issued by the City of Folly Beach to further assist in locating valuable sand resources. Athena provided geological logging, core photography, and laboratory oversight during this project.
Cape San Blas, Florida Vibracore Sampling
Athena collected 53 vibracore samples offshore of Cape San Blas, Florida for a geotechnical evaluation of several borrow areas. Athena also provided geological logging, core photography, and laboratory oversight services.
Vibracore Sampling In Delaware Bay
Athena mobilized to Milford, Delaware in early May to collect 50 vibracore samples, collected to a depth of 20 feet below sediment surface, for a sand source study in Delaware Bay. The dataset collected greatly expanded the Delaware Department of Natural Resources' (DNREC) knowledge of potential sand sources available for beach renourishment projects in the area.
