Vibracores and vibracore transects: constraining the geological and cultural history of St. Catherines Island

Vibracoring is a subsurface sediment acquisition (sediment coring) technique (Pierce and Howard, 1969; Howard and Frey, 1975; Dreher et al., 2008) that returns sediment preserved within its stratigraphic and sedimentologic context. This process (see appendix 1) generates a continuous, contiguous sediment sample at a point by vibrating an aluminum core barrel vertically into the sediment (fig. 10.1). One advantage of vibracoring is that core depths (up to ~7.5 m) can be extracted preserving stratigraphic layering, sedimentary structures, fossils, and lithology in their natural context.
