2 Click to edit Objectives Master title style to establish the degree of mutual benefit in integrating AML and archaeological interpretations of seabed features; to develop compatibility in methodologies, data standards and metadata standards, covering: archaeological methodologies for discerning, discriminating and characterising seabed features; representation of seabed features as points and polygons at different scales; incorporation of digital imagery; accommodating copyright and licensing requirements; to develop good practice in reporting new and/or enhanced wreck data from archaeological sources to the UKHO; to develop good practice in preparing and submitting digital archives to recognised data centres. 2

A number of magnetic anomalies were observed on the wreck site, the largest measuring 155nT. A number of features are visible in the depression, the most prominent ones possibly representing guns. A 11m x 4m depression around 0.4m deep with a number of upstanding features is visible to the west of the main site. The prominent feature within the depression measures 2.3 x 0.7 x 0.3m, orientated west to east. A small depression, measuring 2.5m x 3.5m is situated approximately 15m north of the main site.
