Wreck Monitoring

Contribute to preserving history

The long-term survival of wrecks depends on involvement from the diving community

2004 scheme

In 2004, Wessex Archaeology set up a series of 23 monitoring points around the Iona II wreck. This was to check the sediment level and structural collapse on the wreck site. The points were chosen to be clearly identifiable features of the wreck and relatively easy to find in the future.

Wessex Archaeology and a local dive club have photographed these points to monitor the changes to the site but there proved to be too many points to cover within a dive.

Iona II Monitoring Points


An improved version of the monitoring system has been created for the diver trail. The 12 monitoring points are shown below with the angle at which photographs should be taken. Divers are welcome to contribute to this archive of monitoring photos by uploading photos of the points here to our Flickr groups:
