    Wood conservation - the Mary Rose

    The Mary Rose is a wooden Tudor warship that sank off Portsmouth in 1545. While on the sea bed, most of her hull became covered in silt, which effectively sealed it and the artefacts it contained in anaerobic (air-free) conditions and preserved them from decay.
