Stratigraphy Trench 2 Towards the starboard side the bricks were visible on the surface covered with only a light dusting of grey silt. The sediments between the bricks was a white buttery silt, possibly representing deposition within the hull of suspended sediment as the vessel was still a coherent structure.

This shelly layer may be seabed deposit formed when the upper structure had deteriorated, and the seabed became flat. Beneath this the bricks were stored within buttery silt which was noted by all divers as being cold to touch. Artefacts were within the brick silt/clay layer, Figure 11. Around the more scattered bricks on the east the sediment was white clay with sand contained within it, the bricks were too deeply stored on the west. The amount of sand increased towards the east. Excavations into this layer resulted in many objects although few of these seemed to be bulk cargo objects17 but either personal objects in use or for use within the ship (buckles, spoon, lead sheets (A0406, A0407). Features allocated within trench 2 and the explored area around it included the following: Feature 1 – ROV survey of what appeared to be of a brick structure rather than stored bricks. Feature 3 - Stored bricks Feature 4 – Cylindrical object 17 (B/5/6/7/8A) Dive 98, A0281-A0291, dive 100, A0300-A0307, dive 102,A0308-A0315, dive 103, dive 105, A0317-A0326, dive 104, A0328-A0342; dive 106; dive 111 A0379-A0396 and A0403; dive 114, A0417-A0419, dive 127, A0551-A0552, A0554, A0555, A0559-A0556, A0568, A0575, A0578- A0591 - 39 -
