Using innovative forensic markers to safeguard maritime artefacts

English shipwrecks, submerged for centuries off the coast, hold the secrets of history in the form of artefacts like cannons. However, organised looting poses a significant threat.

To counter this, Historic England and British specialist contractor MSDS Marine have embarked on a ground-breaking project involving underwater forensic tagging technology. This technology, developed over eight years, traces its roots to methods used to protect heritage assets on land. It is applied directly to the marine artefacts and wrecks by divers, and had been trialled on dives this summer.

What does a “frame within a frame” look like in underwater photography? We asked our contributors to share their favorite photos that use “framing” to draw attention to the subject in the image, and they came back with a range of macro to wide-angle shots, featuring a variety of marine life, as well as divers, in wrecks and on reefs.
