Barrel staves

Barrel staves are common finds on "Fredricus". Mostly they are found in a collapsed state prompting careful recording underwater prior to raising the remains.

Macro-phossil samples are taken from every stratigraphical layer and from the areas surrounding (collapsed) stave-built receptacles. Samples are also taken from the sediments within intact receptacles.

These samples might reveal the original contents of the receptacles and perhaps the composition of the ship's victuals.
