Wilmington Harbor 403 Vibracore SamplingAthena collected vibracore samples at 85 locations along the Cape Fear River as part of a beneficial use of dredge material study prior to dredging the navigiation channel. Core lengths ranged from 10-20 feet. Athena provided multiple vibracore vessels to collect the cores and provided geotechnical reporting services.
STA-1 L-4 & L-5 Canal Vibracore SamplingAthena provided vibracore services to collect samples at 40 locations along the L-4 and L-5 canals in the Florida Everglades. Athena provided vibracore services and geological reporting.
Deer Island Restoration ProjectAthena utilized our 35-foot research vessel, Artemis, to collect 73 vibracores up to 20 feet below sediment surface at four areas in Coastal Mississippi and Alabama. This included cores collected adjacent to Deer Island, Mississippi and offshore of Dauphin Island, Alabama. Athena provided geological reporting services in the form of geological logs and vibracore photomosaics. The completed cores were used to determine beneficial use options prior to dredging.
Sagaponack VibracoringAthena mobilized RV Artemis to Sagaponack, NY to collect 30 vibracores offshore for a borrow area evaluation and showing off our ability to get anywhere in the Eastern United States and collected sediment data quickly and cost effectively. This project also marks the farthest east Athena has travelled in the Continental United States.
Hilton Head Island Borrow Area EvaluationAthena collected 48 vibracore samples for a geotechnical evaluation of four borrow areas offshore of Hilton Head Island, South Carolina. Athena provided all vessel support using the company owned research vessel Artemis, which is outfitted with all vibracore systems, navigation systems, and RTK. Water depths ranged from 5 feet on shoal tops to 30+ feet offshore. Athena was then responsible for geotechnical reporting, including core logging, core photo-mosaic production, laboratory oversight, and final reporting of results.
San Juan Harbor Vibracore ProjectsAthena mobilized our highly portable 24-foot sampling vessel, along with equipment and personnel to Puerto Rico to collect sediment samples for vibracores studies in San Juan Harbor, Rio Piedras, and Cano Martin Pena. The vibracores collected in San Juan Harbor were in support of Section 103 studies supporting maintenance dredging and potential deepening of the shipping channel and adjacent berths. The work in Rio Piedras and Cano Martin Pena were studies to determine dredging options in both streams.
