FSU student Ben Tanner returns to the surface after a two-hour dive excavating at the deeper end of the shipwreck. Krister Efverstrom, who has been excavating along the keel at the shallow end of the wreck, has discovered an artifact. After mapping its location within the grid system, he brings it to the surface where it will be stored in water until it can be transported to the conservation laboratory. Sometimes the archaeologists are interrupted by the passage of massive cargo-laden barges, propelled by tugboats. These enormous vessels are the modern inheritors of the historic maritime trade of St. Mark s.
Divers continue to expose as much of the wreck as possible.
Deeper trenches are excavated at either end of the keel, in an attempt to study how the keel articulates to the rest of the hull in order to determine which end of the ship is which. Unfortunately, despite the relatively good preservation elsewhere in the hull, both ends of the keel are badly deteriorated. The shape of some of these make them look like rudder hardware. This, of course, would suggest that the stern of the vessel may be at the deeper end of the wreck. This concreted, U-shaped iron object, for example, may be a gudgeon, one of the straps attached to the stern post from which the rudder was hung.
